DEVICE OVERVIEW
This document contains device specific information for
the following devices:
These devices come in 28-pin and 40/44-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.
The following two figures are device block diagrams
sorted by pin count: 28-pin for Figure 1-1 and 40/44-pin
for Figure 1-2. The 28-pin and 40/44-pin pinouts are
listed in Table 1-2 and Table 1-3, respectively.
