C8051F350/1/2/3
1.2.
The C8051F350/1/2/3 devices include on-chip Silicon Labs 2-Wire (C2) debug circuitry that provides non-
intrusive, full speed, in-circuit debugging of the production part installed in the end application.
Silicon Labs' debugging system supports inspection and modification of memory and registers, break-
points, and single stepping. No additional target RAM, program memory, timers, or communications chan-
nels are required. All the digital and analog peripherals are functional and work correctly while debugging.
All the peripherals (except for the ADC and SMBus) are stalled when the MCU is halted, during single
stepping, or at a breakpoint in order to keep them synchronized.
The C8051F350DK development kit provides all the hardware and software necessary to develop applica-
tion code and perform in-circuit debugging with the C8051F350/1/2/3 MCUs. The kit includes software with
a developer's studio and debugger, an integrated 8051 assembler, and an RS-232 to C2 serial adapter. It
also has a target application board with the associated MCU installed and prototyping area, plus the RS-
232 and C2 cables, and wall-mount power supply. The Development Kit requires a Windows
95/98/NT/ME/2000 computer with one available RS-232 serial port. As shown in Figure 1.5, the PC is con-
nected via RS-232 to the Serial Adapter. A six-inch ribbon cable connects the Serial Adapter to the user's
application board, picking up the two C2 pins, V
application board. For applications where there is not sufficient power available from the target board, the
provided power supply can be connected directly to the Serial Adapter.
The Silicon Labs IDE interface is a vastly superior developing and debugging configuration, compared to
standard MCU emulators that use on-board "ICE Chips" and require the MCU in the application board to
be socketed. Silicon Labs' debug paradigm increases ease of use and preserves the performance of the
precision analog peripherals.
