PIC16F87/88
1.0 DEVICE OVERVIEW
This document includes programming specifications
for the following devices:
•PIC16F87
•PIC16F88
2.0 PROGRAMMING THE
PIC16F87/88
The PIC16F87/88 is programmed using a serial
method. The Serial mode will allow the PIC16F87/88 to
be programmed while in the user’s system, which
allows for increased design flexibility. This
programming specification applies to PIC16F87/88
devices in all packages.
2.1 Programming Algorithm
Requirements
The programming algorithm used depends on the
operating voltage (V
DD) of the PIC16F87/88 device.
Both algorithms can be used with the two available
programming entry methods. The first method, called
Low-Voltage ICSP
TM
(LVP for short), applies VDD to
MCLR
and uses the I/O pin RB3 to enter Programming
mode. When RB3 is driven to V
DD from ground, the
PIC16F87/88 device enters Programming mode. The
second method follows the normal Microchip
Programming mode entry of holding pins RB6 and RB7
low, while raising the MCLR pin from VIL to VIHH
(13V ± 0.5V).
2.2 Programming Mode
The Programming mode for the PIC16F87/88 allows
programming of user program memory, data memory,
special locations used for ID, and the Configuration
Words.
