PostHeaderIcon Recover MCU PIC16F648A Firmware

We can recover MCU PIC16F648A Firmware, please view the Microchip MCU PIC16F648A features for your reference:

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 the PIC16F648A Product Identification System, at the end of this data sheet. When placing orders, please use this page of the data sheet to specify the correct part number when recover MCU.

FLASH Devices

FLASH devices can be erased and re-programmed electrically. This allows the same device to be used for prototype development, pilot programs and production. A further advantage of the electrically erasable FLASH 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 after recover MCU.

Quick-Turnaround-Production

(QTP) Devices Microchip offers a QTP Programming Service for factory production orders. This service is made available for users who chose not to program a medium to high quantity of units and whose code patterns have stabilized. The devices are standard FLASH devices but with all program locations and configuration options already programmed by the factory. Certain code and prototype verification procedures apply before production shipments are available. Please contact your Microchip Technology sales office for more details if recover MCU.

Serialized Quick-Turnaround Production (SQTPSM) Devices

Microchip offers a 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 for the purpose of recover MCU.

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

Data memory is composed of registers or bytes of RAM. Therefore, data memory for a device is specified by its register file. The register file is divided into two functional groups: Special Function Registers (SFR) and General Purpose Registers (GPR) after Recover PIC MCU.

The Special Function Registers include the TMR0 register, the Program Counter (PCL), the STATUS register, the I/O registers (ports) and the File Select Register (FSR). In addition, Special Function Registers are used to control the I/O port configuration and prescaler options when Recover PIC MCU.

The General Purpose Registers are used for data and control information under command of the instructions. For the PIC12F510, the register file is composed of 10 Special Function Registers, 6 General Purpose if Recover PIC MCU.

Registers and 32 General Purpose Registers accessed For the PIC16F506, the register file is composed of 13 Special Function Registers, 3 General Purpose Registers and 64 General Purpose Registers accessed for Recover PIC MCU.

The Special Function Registers (SFRs) are registers used by the CPU and peripheral functions to control the operation of the device (see Table 4-1).

The Special Function Registers can be classified into two sets. The Special Function Registers associated with the “core” functions are described in this section for the purpose of Recover PIC MCU.

Those related to the operation of the peripheral features are described in the section for each peripheral feature.

This register contains the arithmetic status of the ALU, the Reset status and the page preselect bit.

The STATUS register can be the destination for any instruction, as with any other register. If the STATUS register is the destination for an instruction that affects the Z, DC or C bits, then the write to these three bits is disabled. These bits are set or cleared according to the device logic. Furthermore, the TO and PD bits are not writable. Therefore, the result of an instruction with the STATUS register as destination may be different than intended.

For example, CLRF STATUS, will clear the upper three bits and set the Z bit. This leaves the STATUS register

as 000u u1uu (where u = unchanged).

Therefore, it is recommended that only BCF, BSF and MOVWF instructions be used to alter the STATUS register. These instructions do not affect the Z, DC or C bits from the STATUS register. For other instructions which do affect Status bits.
