This document contains device specific information for
the PIC12F635/PIC16F636/639 devices. Additional
information may be found in the “PICmicro
MCU Family Reference Manual” (DS33023), which may
be
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.
