PIC16C712/716
1.0 DEVICE OVERVIEW
This document contains device-specific information.
Additional information may be found in the PIC
®
Mid-
Range Reference Manual, (DS33023), which may be
obtained from your local Microchip Sales Representa-
tive or downloaded from the Microchip web site. 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 (PIC16C712, PIC16C716)
covered by this data sheet.
Figure 1-1 is the block diagram for both devices. The
pinouts are listed in Table 1-1.
