Product Summary
The PIC16F877A-IP is an Enhanced Flash Microcontroller. Additional information may be found in the PICmicro Mid-Range Reference Manual (DS33023), which may be obtained from your local Microchip Sales Representative or downloaded from the Microchip web site. The 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.
