Preliminary
2.1 56F8013
The 56F8013 Demonstration Board uses a Freescale 56F8013 part, designated as U1 on the board
and in the schematics. This part will operate at a maximum external bus speed of 60MHz. A full
description of the 56F8013, including functionality and user information, is provided in these
documents:

2.2 RS-232 Serial Communications
The 56F8013 Demonstration Board provides an RS-232 interface by the use of an RS-232 level
converter, Sipex SP3220EUCY, designated as U2. Refer to the RS-232 schematic details in
Appendix A
. The RS-232 level converter transitions the SCI port’s +3.3V signal levels to
RS-232-compatible signal levels and connects to the host’s serial port via connector P3. The SCI
ports signals, GPIOB6 and GPIOB7, can be disconnected from the RS-232 level converter by
cutting the JP1 and JP2 jumpers on the board. The pin-out of connector P2 is shown in
Table 2-1
