PICI7C Processor Board
The PIC17C computer described in this article is a flexible and easily expandable system which is comfortably programmed by a PC rather than a costly, dedicated programmer. At the heart of the system is the extremely fast and powerful PIC17C756 microcontroller from Microchip Technology.With microcontroller systems featuring ‘in-system’ programming, the monitor program is usually stored in an external EPROM. This requires that the controller is capable of disabling its complete internal program memory, and fetch all instructions from an external memory. Furthermore, the external memory structure should be highly similar, if not equal, to that of the internal memory (in this case, having a width of 16 bits).
