The C8051F300/1/2/3/4/5 devices include on-chip Silicon Labs 2-Wire (C2) debug circuitry that provides non-intru-
sive, 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, breakpoints, and sin-
gle stepping. No additional target RAM, program memory, timers, or communications channels 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 C8051F300DK development kit provides all the hardware and software necessary to develop application code
and perform in-circuit debugging with the C8051F300/1/2/3/4/5 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 large 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 1.6, the PC is connected 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 and VDD and GND. The
Serial Adapter takes its power from the application board; it requires roughly 20 mA at 2.7-3.6V. 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.
