This document contains device specific information for
the operation of the PIC16F87/88 devices. Additional
information may be found in the “PICmicro
MCU Family Reference Manual” (DS33023) which may
be downloaded from the Microchip web site. This
Reference Manual should be considered a comple-
mentary document to this data sheet and is highly
recommended reading for a better understanding of the
device architecture and operation of the peripheral
modules.
The PIC16F87/88 belongs to the Mid-Range family of

TABLE 1-1:
There are 16 I/O pins that are user configurable on a
pin-to-pin basis. Some pins are multiplexed with other
device functions. These functions include:
• External Interrupt
• Change on PORTB Interrupt
• Timer0 Clock Input
• Low-Power Timer1 Clock/Oscillator
• Capture/Compare/PWM
• 10-bit, 7-channel A/D Converter (PIC16F88 only)
• SPI™/I
• Two Analog Comparators
• AUSART
• MCLR (RA5) can be configured as an input
