DEVICE OVERVIEW
This document contains device specific information for
the rfPIC12F675. Additional information may be found
in the PICmicroTM 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.
The rfPIC12F675 comes in a 20-pin SSOP package.
Figure 1-1 shows a block diagram of the rfPIC12F675
device. Table 1-1 shows the pinout description.
