This page was last edited on 10 November 2017, at 09:08. EPROM for program storage, some with provision for erasing memory. Program memory and data memory are separated.

Data memory is 8-bit, 16-bit, and, in latest models, 32-bit wide. Program instructions vary in bit-count by family of PIC, and may be 12, 14, 16, or 24 bits long. Low-power and high-speed variations exist for many types. Third party and some open-source tools are also available. PIC devices are popular with both industrial developers and hobbyists due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, serial programming, and re-programmable Flash-memory capability. O tasks from the CPU. In 2001, Microchip introduced Flash programmable devices, with full production commencing in 2002.

PIC and PICmicro are registered trademarks of Microchip Technology. Microchip CPU with on-chip EEPROM memory. By 2013, Microchip was shipping over one billion PIC microcontrollers every year. The baseline and mid-range families use 8-bit wide data memory, and the high-end families use 16-bit data memory. The program memory of “C” devices is variously described as OTP, ROM, or EEPROM.

As of October 2016, the only OTP product classified as “In production” is the pic16HV540. These devices feature a 12-bit wide code memory, a 32-byte register file, and a tiny two level deep call stack. They are represented by the PIC10 series, as well as by some PIC12 and PIC16 devices. Baseline devices are available in 6-pin to 40-pin packages. Generally the first 7 to 9 bytes of the register file are special-purpose registers, and the remaining bytes are general purpose RAM. If banked RAM is implemented, the bank number is selected by the high 3 bits of the FSR. 15 are global and not affected by the bank select bits.
