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