The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle.

The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

The ATtiny261/461/861 provides the following features: 2/4/8K byte of In-System Programmable Flash, 128/256/512 bytes EEPROM, 128/256/512 bytes SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one 8-bit Timer/Counter with compare modes, one 8-bit high speed Timer/Counter, Universal Serial Interface, Internal and External Interrupts, a 4-channel, 10-bit ADC, a programmable Watchdog Timer with internal Oscillator, and three software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counter, ADC, Analog Comparator, and Interrupt system to continue functioning.

The Power-down mode saves the register contents, disabling all chip functions until the next Interrupt or Hardware Reset. The ADC Noise Reduction mode stops the CPU and all I/O modules except ADC, to minimize switching noise during ADC conversions if Recover mcu at89c4051 heximal.

The fast-access register file concept contains 32 x 8-bit general purpose working registers with a single clock cycle access time. This means that during one single clock cycle, one ALU (Arithmetic Logic Unit) operation is executed. Two operands are output from the register file, the operation is executed, and the result is stored back in the register file – in one clock cycle.

Six of the 32 registers can be used as three 16-bits indirect address register pointers for Data Space addressing – enabling efficient address calculations. One of the three address pointers is also used as the address pointer for the constant table look up function after Recover 430g2452 Microcontroller heximal.

These added function registers are the 16-bits X-register, Y-register and Z-register. The ALU supports arithmetic and logic functions between registers or between a constant and a register. Single register operations are also executed in the ALU.

Figure 4 shows the AT90S2313 AVR Enhanced RISC microcontroller architecture. In addition to the register operation, the conventional memory addressing modes can be used on the register file as well. This is enabled by the fact that the register file is assigned the 32 lowermost Data Space addresses ($00 – $1F), allowing them to be accessed as though they were ordinary memory locations before break LPC2132FBD64 firmware.

The I/O memory space contains 64 addresses for CPU peripheral functions as Control Registers, Timer/Counters, A/D-converters, and other I/O functions. The I/O memory can be accessed directly, or as the Data Space locations following those of the register file, $20 – $5F.

The device is manufactured using Atmel’s high density non-volatile memory technology. The On-chip ISP Flash allows the Program memory to be re-programmed In-System through an SPI serial interface, by a conventional non-volatile memory programmer or by an On-chip boot code running on the AVR core.

The ATtiny261/461/861 AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators, and Evaluation kits.

Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port A output buffers have symmetrical drive characteristics with both high sink and source capability.

As inputs, Port A pins that are externally pulled low will source current if the pull-up resistors are activated. The Port A pins are tri-stated when a reset condition becomes active, even if the clock is not running after Recover MCU.

Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buffers have symmetrical drive characteristics with both high sink and source capability.

As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running.

For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses should never be written.

I/O Registers within the address range 0x00 – 0x1F are directly bit-accessible using the SBI and CBI instructions. In these registers, the value of single bits can be checked by using the SBIS and SBIC instructions.

Some of the Status Flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI instructions will only operation the specified bit, and can therefore be used on registers containing such Status Flags. The CBI and SBI instructions work with registers 0x00 to 0x1F only.

By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic mcu, the Atmel ATtiny2313A/4313 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.

The ATtiny2313A/4313 AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators, and Evaluation kits.

This documentation contains simple code examples that briefly show how to use various parts of the device. These code examples assume that the part specific header file is included before compilation. Be aware that not all C compiler vendors include bit definitions in the header files and interrupt handling in C is compiler dependent before attack st62t15c6 Mcu firmware.

Please confirm with the C compiler documentation for more details.

For I/O Registers located in the extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI” instructions must be replaced with instructions that allow access to extended I/O. Typically, this means “LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.

A variety of frequency ranges and packaging options are available. Depending on application and production requirements the proper device option can be selected using the information in this section. When placing orders, please use the “PIC16F8X Product Identification System” at the back of this data sheet to specify the correct part number.

There are four device “types” as indicated in the device number.

1. F, as in PIC16F84. These devices have Flash program memory and operate over the standard voltage range after Attack MCU.

2. LF, as in PIC16LF84. These devices have Flash program memory and operate over an extended voltage range.

3. CR, as in PIC16CR83. These devices have ROM program memory and operate over the standard voltage range.

4. LCR, as in PIC16LCR84. These devices have ROM program memory and operate over an extended voltage range if Attack attiny2313 MCU memory.

When discussing memory maps and other architectural features, the use of F and CR also implies the LF and LCR versions.

2.1 Flash Devices

These devices are offered in the lower cost plastic package, even though the device can be erased and reprogrammed. This allows the same device to be used for prototype development and pilot programs as well as production.

A further advantage of the electrically-erasable Flash version is that it can be erased and reprogrammed in-circuit, or by device programmers, such as Microchip’s PICSTART® Plus or PRO MATE® II programmers when copy avr atmega165a memory file.

2.2 Quick-Turnaround-Production (QTP) Devices

Microchip offers a QTP Programming Service for factory production orders. This service is made available for users who choose not to program a medium to high quantity of units and whose code patterns have stabilized.

The devices have all Flash locations and configuration options already programmed by the factory. Certain code and prototype verification procedures do apply before production shipments are available.

2.3 Serialized Quick-Turnaround-Production (SQTP SM ) Devices

Microchip offers the unique programming service where a few user-defined locations in each device are programmed with different serial numbers. The serial numbers  may  be  random,  pseudo-random or sequential.

Serial programming allows each device to have a unique number which can serve as an entry-code, password or ID number.

Some of Microchip’s devices have a corresponding device where the program memory is a ROM. These devices give a cost savings over Microchip’s traditional user programmed devices (EPROM, EEPROM) when Attack MCU. ROM devices (PIC16CR8X) do not allow serialization information in the program memory space.

The user may program this information into the Data EEPROM.

The high performance of the PIC16CXX family can be attributed to a number of architectural features commonly found in RISC microprocessors. To begin with, the PIC16CXX uses a Harvard architecture. This architecture has the program and data accessed from separate memories. So the device has a program memory bus and a data memory bus.

This improves bandwidth over traditional von Neumann architecture where program and data are fetched from the same memory (accesses over the same bus) after Attack MCU. Separating program and data memory further allows instructions to be sized differently than the 8-bit wide data word. PIC16CXX opcodes are 14-bits wide, enabling single word instructions.

The full 14-bit wide program memory bus fetches a 14-bit instruction in a single cycle. A two-stage pipeline overlaps fetch and execution of instructions (Example 3-1). Consequently, all instructions execute in a single cycle except for program branches when copy pic12c509 MCU program.

The PIC16F83 and PIC16CR83 address 512 x 14 of program memory, and the PIC16F84 and PIC16CR84 address 1K x 14 program memory. All program memory is internal.

XTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier which can be configured for use as an on-IC oscillator, as shown in Figure 1. Either a quartz crystal or ceramic resonator may be used. To drive the device from an external clock source, XTAL2 should be left unconnected while XTAL1 is driven as shown in Figure 2. There are no requirements on the duty cycle of the external clock signal, since the input to the internal clocking circuitry is through a divide-by-two flip-flop, but minimum and maximum voltage high and low time specifications must be observed.

In idle mode, the CPU puts itself to sleep while all the on-IC peripherals remain active. The mode is invoked by software. The content of the on-IC RAM and all the special functions registers remain unchanged during Break mcu pic16f876 memory.

Figure 2. External Clock Drive Configuration mode. The idle mode can be terminated by any enabled interrupt or by a hardware reset before Break IC. It should be noted that when idle is terminated by a hardware reset, the device normally resumes program execution, from where it left off, up to two machine cycles before the internal reset algorithm takes control. On-IC hardware inhibits access to internal RAM in this event, but access to the port pins is not inhibited.

To eliminate the possibility of an unexpected write to a port pin when Idle is terminated by reset, the instruction following the one that invokes Idle should not be one that writes to a port pin or to external memory. In the power down mode the oscillator is stopped, and the instruction that invokes power down is the last instruction executed. The on-IC RAM and Special Function Registers retain their values until the power down mode is terminated.

The only exit from power down is a hardware reset. Reset redefines the SFRs but does not change the on-IC RAM. The reset should not be activated before VCC is restored to its normal operating level and must be held active long enough to allow the oscillator to restart and stabilize if Break IC.
