![]() ![]() Low-power and high-speed variations exist for many types. The hardware capabilities of PIC devices range from 6-pin SMD, 8-pin DIP chips up to 144-pin SMD chips, with discrete I/O pins, ADC and DAC modules, and communications ports such as UART, I2C, CAN, and even USB. The instruction set also varies by model, with more powerful chips adding instructions for digital signal processing functions. Program instructions vary in bit-count by family of PIC, and may be 12, 14, 16, or 24 bits long. Data memory is 8-bit, 16-bit, and, in latest models, 32-bit wide. Program memory and data memory are separated (see Harvard architecture). All current models use flash memory for program storage, and newer models allow the PIC to reprogram itself. The first parts of the family were available in 1976 by 2013 the company had shipped more than twelve billion individual parts, used in a wide variety of embedded systems.Įarly models of PIC had read-only memory (ROM) or field-programmable EPROM for program storage, some with provision for erasing memory. The name PIC initially referred to Peripheral Interface Controller, Īnd is currently expanded as Programmable Intelligent Computer. ![]() PIC (usually pronounced as "pick") is a family of microcontrollers made by Microchip Technology, derived from the PIC1650 originally developed by General Instrument's Microelectronics Division.
