TIMING
The TWR-S12G128 internal timing source is active from RESET by default. An external 8MHz
crystal oscillator, configured for low-power operation, is also installed. Refer to the target
device RM for details on selecting and configuring the desired timing source.
COMMUNICATIONS
Communications options for the TWR-S12G128 include serial RS-232, LIN, and CAN. Serial
RS-232 communications is supported through a RS-232 physical layer device (PHY) and a 2x5
pin header. A high-speed, enhanced, LIN PHY provides LIN bus communications through a
2x2 Molex connector (pn 39-29-1048).
A high-speed CAN PHY provides CAN bus
communications through a 1 x 4 Molex connector (pn 39-30-3045).
Connecting LIN cables require Molex housing, pn 39-01-2040 and pins, pn 39-00-0217.
Connecting CAN cables require Molex housing, pn 39-01-4040, and pins, pn 39-00-0217.
The COM_SEL option header connects the MCU SCI signal to either the LIN PHY or the RS-
232 PHY. See Figure 6 below for jumper position options. See Figure 4 below for jumper
position options.
RS-232
The TWR-S12G128 applies the MAX3387E, RS-232 transceiver to support serial
communications. A standard 2x5 “Berg” pin - header on 0.1” centers and an IDC to DB9 cable
supports connecting standard serial cables to the target board. Figure 4 below shows the SCI
signal connections.
