    Overview

    The USB Debug Adapter provides the interface between the PC's USB port and the C8051Fxxx’s in-system debug/programming circuitry. The attached 10-pin debug ribbon cable connects the adapter to the target board and the target device’s debug interface signals (the USB Debug Adapter supports both Silicon Labs JTAG and C2 debug interfaces.) Power is provided to the adapter from the USB connection to the PC. The USB Debug Adapter is capable of providing power to some of the Silicon Labs' circuit boards via pin 10 of the debug connector

    The 8-bit USB Debug Adapter (UDA) provides the interface between the PC’s USB port and the Silicon Labs 8-bit target device's in-system debug/programming circuitry. The 10-pin ribbon cable connects the adapter to the target board and the target device’s debug interface.

    The 8-Bit USB Debug Adapter supports both Silicon Laboratories JTAG and C2 debug interfaces, and the adapter is powered from the USB connection to the PC. The UDA is also capable of providing power to the target device or other circuitry via pin 10 of the connector.

    The USB Debug Adapter can automatically change the communication voltage level based on the level detected on pin 7 of the connector. As a result, this pin should be pulled high with a strong pull-up (~1 kΩ) for noise immunity purposes and not pulled down to ground.

    Notes:

    • The USB Debug Adapter requires a target system clock of 32 kHz or greater.
    • With the default settings, the USB Debug Adapter can supply up to 100 mA to a target system.
