The microcontroller family features a highly efficient enhanced 8051 pipelined architecture with 2 to 8 kB flash, 256/512 byte RAM, a 12-bit multi-channel analog to digital converter (ADC), a precise internal voltage reference, two analogue comparators with programmable hysteresis and response time, an extended temperature range (up to 125 °C) and a host of communication peripherals (SMBus/I2C, SPI, UART).
Other features include: C8051F850 MCU Board, Wall-mounted universal power supply, USB cable and debug adapter, C8051F850 Development Kit Quick Start Guide and Development Kit CD
A host PC is required to run the development kit software and communicate with the debug adapter. The PC must run Windows 2000 or later and have one available USB port.
Since the MCU has built in debug capabilities, it can be installed into the end application. The kit supports the following debug features: Run, halt and single-step; Set hardware breakpoints; Inspect/Modify memory and registers; Download program memory.
