This document contains device specific information for
the following four devices:
1.
2.
3.
4.
These devices come in 28-pin and 40-pin packages.
The 28-pin devices do not have a Parallel Slave Port
(PSP) implemented and the number of Analog-to-
Digital (A/D) converter input channels is reduced to 5.
An overview of features is shown in Table 1-1.
