In computing, a programmable interrupt controller (PIC) is an integrated circuit that helps a microprocessor (or CPU) handle interrupt requests (IRQs) coming from multiple different sources (like external I/O devices) which may occur simultaneously. [1]
Various older (EPROM) PIC microcontrollers. The original PIC was intended to be used with General Instrument's new CP1600 16-bit central processing unit (CPU). In order to fit 16-bit data and address buses into a then-standard 40-pin dual inline package (DIP) chip, the two buses shared the same set of 16 connection pins. In order to communicate ...
Some models support multiple ROM or RAM banks, in a manner similar to other PIC microcontrollers. There is also a 15-bit variant of the instruction set, which is almost identical except that the register numbers are enlarged to 8 bits and the call and jump addresses are enlarged to 12 bits.
The PIC16C84, PIC16F84 and PIC16F84A are 8-bit microcontrollers of which the PIC16C84 was the first introduced in 1993 [citation needed] and hailed [by whom?] as the first PIC microcontroller to feature a serial programming algorithm and EEPROM memory. [citation needed] It is a member of the PIC family of controllers, produced by Microchip ...
The intent of PICKitPlus is to facilitate the programming of any 8-bit PIC microcontroller using the PICkit™ 2 and PICkit™ 3 (ICSP) In-Circuit Debuggers/Programmers. The software extends the life of the existing PICkit2 and PICkit3 hardware devices by allowing them to work with the newer 8-bit PIC microcontrollers. The capabilities include:
PICAXE 20M2. PICAXE is a microcontroller system based on a range of Microchip PIC microcontrollers.PICAXE devices are Microchip PIC devices with pre-programmed firmware that enables bootloading of code directly from a PC, simplifying hobbyist embedded development (not unlike the Arduino and Parallax BASIC Stamp systems).
PIC: Board based on a PIC microcontroller, with native USB support and compatibility with the Arduino programming language plus an IDE built with Python and sdcc as compiler. Unduino [250] PIC: A board based on the dsPIC33FJ128MC202 microcontroller, with integrated motor control peripherals. Netduino N2 [251] Wilderness Labs [251] Yes Cortex M3 ...
Pic Micro Pascal a.k.a. PMP is a free Pascal cross compiler for PIC microcontrollers. It is intended to work with the Microchip Technology MPLAB suite installed; it has its own IDE (Scintilla-based) and it is a highly optimized compiler. It is intended to target 8-bit processors only: PIC10, PIC12, PIC16, PIC16 enhanced, PIC18.
