The C8051F816-GS is a low-pin-count, low-power 8-bit microcontroller with a 16-bit CPU core from Silicon Labs. It has an 8051 core, 512 bytes of on-chip RAM, 8KB of Flash memory, and an LCD controller/driver. It offers an integrated 8-bit analog-to-digital converter (ADC) and four 8-bit digital-to-analog converters (DACs). The device includes four 16-bit timer/counters, two 16-bit counters, two 16-bit capture/compare modules, a programmable serial port, four general-purpose input/output (GPIO) ports, and a clock circuit with an internal oscillator. It operates over a wide range of supply voltages (2.5V to 3.6V). The device also operates over a wide temperature range (-40°C to +85°C).
