Freescale Semiconductor

Preliminary

2.3 RS-232 Serial Communications

The 56F8357EVM provides an RS-232 interface by the use of an RS-232 level converter, Maxim
MAX3245EEAI, designated as U4. Refer to the RS-232 schematic diagram in

Figure 2-3

. The

RS-232 level converter transitions the SCI UART’s +3.3V signal levels to RS-232-compatible
signal levels and connects to the host’s serial port via connector P2. RTS/CTS flow control is
provided on JG11 as a jumper, but could be implemented using uncommitted GPIO signals. The
SCI0 port signals can be isolated from the RS-232 level converter by removing the jumpers in
JG9; see

Table 2-1

. The pin-out of connector P2 is listed in

Table 2-2

. The RS-232 level

converter/transceiver can be disabled by placing a jumper at JG10.
