PIC12F635/PIC16F636/639

1.0 DEVICE OVERVIEW

This document contains device specific information for

the PIC12F635/PIC16F636/639 devices. Additional

information may be found in the “PICmicro® Mid-Range

MCU Family 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.
