DEVICE MIGRATIONS
This document is intended to describe the functional differences and the electrical specification differences that are
present when migrating from one device to the next.
Table 1 shows the considerations that must be taken into account when migrating from the PIC16C56 to the
PIC16C56A.
TABLE 1: PIC16C56 → PIC16C56A DIFFERENCES
Note: This device has been designed to perform to the parameters of its data sheet. It has been tested to an elec-
trical specification designed to determine its conformance with these parameters. Due to process differ-
ences in the manufacture of this device, this device may have different performance characteristics than its
earlier version. These differences may cause this device to perform differently in your application than the
earlier version of this device.
Functional Differences
No. Difference H/W S/W Prog.
