versions of these chips can be ordered. The F in a PICMicro part number generally indicates the PICmicro uses flash memory and can be erased electronically

processor, and automatically executed by the microcontroller on startup. PICmicro chips have a Harvard architecture and instruction words have unusual sizes

microcontrollers that are still popular as of 2014[update], such as the PICmicro and 8051, are accumulator-based machines. Modern CPUs are typically 2-operand

microcontrollers with three very different architectures: 8-bit (8-bit data bus) PICmicro, with a single accumulator (8 bits): PIC10 and PIC12: 12-bit instruction

operation "subtract with carry" (SBWC, SUBC, SUBWC and SBC). The PA-RISC and PICmicro architectures use the carry bit convention, but call their a+not(b)+C operation
