PIC16C781/782
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 website. The
Reference manual should be considered a comple-
mentary document to this data sheet. The Reference
manual is highly recommended reading for a better
understanding of the device architecture and operation
of the peripheral modules.
This data sheet covers two devices: PIC16C781 and
PIC16C782. Both devices come in a variety of 20-pin
packages.
The following figures are block diagrams of the
PIC16C781 and the PIC16C782.
