PIC16C62B/72A

1.0 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.
