Microchip offers a unique programming service where a few user-defined locations in each device are programmed with different serial numbers when recover microcontroller stm32f105rct6 binary.

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.

The high performance of the PIC12C5XX family can be attributed to a number of architectural features commonly found in RISC microprocessors.

To begin with, the PIC12C5XX uses a Harvard architecture in which program and data are accessed on separate buses. This improves bandwidth over traditional von Neumann architecture where program and data are fetched on the same bus.

Separating program and data memory further allows instructions to be sized differently than the 8-bit wide data word. Instruction opcodes are 12-bits wide making it possible to have all single word instructions when break microcontroller atmega128 heximal.

A 12-bit wide program memory access bus fetches a 12-bit instruction in a single cycle. A two-stage pipeline overlaps fetch and execution of instructions. Consequently, all instructions (33) execute in a single cycle (1µs @ 4MHz) except for program branches.

The table below lists program memory (EPROM), data memory (RAM), ROM memory, and non-volatile (EEPROM) for each device.

The PIC12C5XX can directly or indirectly address its register files and data memory. All special function registers including the program counter are mapped in the data memory. The PIC12C5XX has a highly orthogonal (symmetrical) instruction set that makes it possible to carry out any operation on any register using any addressing mode.

This symmetrical nature and lack of ‘special optimal situations’ make programming with the PIC12C5XX simple yet efficient. In addition, the learning curve is reduced significantly.
