The RS232 Serial Adapter (EC2) package contains the following items:
2. RS232 Serial Adapter (EC2)
The RS232 Serial Adapter provides the interface between the PC’s RS232 serial port and the target device’s in-
system debug/programming circuitry. The included 10-pin DEBUG ribbon cable connects the adapter to the target
board and the target device’s debug interface. The Serial Adapter supports both Silicon Laboratories JTAG and C2
debug interfaces. RS232 Serial Adapters can be powered from the target board, but they cannot provide power to
the target board. Table 1 shows the pin definitions for the DEBUG ribbon cable connector.
Notes:
Rev. 0.1 8/06
When powering the RS232 Serial Adapter via the DEBUG connector, the input voltage to the DEBUG
connector’s power pin must be 3.0 to 3.6 VDC. Otherwise, the Serial Adapter must be powered directly by
connecting the ac/dc adapter to the Serial Adapter’s dc power jack.
The RS232 Serial Adapter requires a target system clock of 32 kHz or greater.
