DEVICE OVERVIEW
This document contains device specific information for the operation of the PIC16F818/819 devices. Additional information may be found in the “PICmicro® Mid-Range MCU Family Reference Manual” DS33023 which may be downloaded from the 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
