This document contains device-specific information for
the following four devices:
1.
2.
3.
4.
These devices come in 28 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.
