DEVICE OVERVIEW
This document contains device-specific information.
Additional information may be found in the PICmicro
Mid-Range Reference Manual, (DS33023), which may
be obtained from your local Microchip Sales Represen-
tative or downloaded from the Microchip website. The
Reference Manual should be considered a comple-
mentary document to this data sheet, and is highly rec-
ommended reading for a better understanding of the
device architecture and operation of the peripheral
modules.
There are two devices (PIC16C62B, PIC16C72A) cov-
ered by this datasheet. The PIC16C62B does not have
the A/D module implemented.
Figure 1-1 is the block diagram for both devices. The
pinouts are listed in Table 1-1.
