EPROM Memory Programming Specification

This document includes the programming

specifications for the following devices:

1.2

Programming Mode

The Programming mode for the PIC16C50X allows

programming of user program memory, and the config-

uration word for the PIC16C50X.

Pin Diagram

PDIP, SOIC, Windowed CERDIP

The PIC16C50X can be programmed using a serial

method. Due to this serial programming, the

PIC16C50X can be programmed while in the user’s

system, increasing design flexibility. This programming

specification applies to PIC16C50X devices in all

packages.

Hardware Requirements

The PIC16C50X requires two programmable power

supplies, one for VDD (2.0V to 6.5V recommended) and

one for VPP (12V to 14V). Both supplies should have a

minimum resolution of 0.25V.
