PIC16C5X
This document includes the programming
specifications for the following devices:
INTRODUCTION
Overview
The PIC16C5X Series is a family of single-chip CMOS
microcontrollers with on-chip EPROM for program stor-
age. The programming specification also applies to
ROM products for verification only.
Due to the special architecture of these microcontrol-
lers (12-bit wide instruction word) and the low pin
counts (starting at 18 pins), the EPROM programming
methodology is different from that of standard
(byte-wide) EPROMs (e.g., 27C256).
The PIC16C5X Series can be programmed by applying
the 12-bit wide data word to the 12 available I/O pins
while the address is generated by the on-chip Program
Counter. The MCLR
/V
PP
pin provides the programming
supply voltage (V
PP
). Programming/verify chip enable
is controlled by the T0CKI pin while the OSC1 pin con-
trols the Program Counter.
This document describes all the programming details
of the PIC16C5X Series and the requirements for pro-
gramming equipment to be used from programming
prototypes in the engineering lab up to high volume
programming on the factory floor.
