C8051F85x/86x 8-bit Flash MCUs Silicon Labs C8051F85x and C805186x 8-bit Flash microcontrollers are highly integrated AEC-Q100 (automotive) qualified MCUs featuring a highly-efficient enhanced 8051 pipelined architecture. These Silicon labs MCUs offer 2 to 8kB Flash, 256/512b RAM, and a 12-bit multi-channel analog to digital converter (ADC). C8051F85x and C8051F86x operate over an extended temperature range (up to 125°C) and include a host of communication peripherals (SMBus/I2C, SPI, UART). This Silicon Labs MCU family also supports three independently configurable enhanced resolution PWM channels and has built-in hardware kill/safe state capability for overcurrent protection and fault detection. C8051F85x and C8051F86x MCUs are an ideal fit for low-memory, low-pin count applications. Development tools are available to evaluate the functionality of these high-performance MCUs.
