Description

The high performance of the PIC16F627 family can beattributed to a number of architectural featurescommonly found in RISC microprocessors. To beginwith, the PIC16F62X uses a Harvard architecture, inwhich, program and data are accessed from separatememories using separate buses. This improvesbandwidth over traditional Von Neumann architecturewhere program and data are fetched from the samememory. Separating program and data memory furtherallows instructions to be sized differently than 8-bitwide data word. Instruction opcodes are 14-bits widemaking PIC16F627 possible to have all single-word instructions.
