C8051F85x Small Form Factor MCUs

The C8051F85x is a highly integrated AEC-Q100 qualified MCU product family without any compromise on features or performance.

The C8051F85x/6x devices feature 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 analog 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). In addition, this product family supports three independently configurable enhanced resolution PWM channels and also has built-in hardware kill/safe state capability for overcurrent protection and fault detection.
