C8051F120 Description

Short technical summary and product information.

The C8051F120 is a high-performance 8-bit microcontroller from Silicon Labs, built around the 8051 core with a pipelined architecture that achieves up to 100 MIPS throughput. It integrates 128KB of in-system programmable Flash memory and 8.25KB of internal data RAM. The device includes a rich set of analog peripherals: two 12-bit DACs, a 12-bit SAR ADC (up to 100 ksps) and an 8-bit SAR ADC (up to 500 ksps), along with a temperature sensor and voltage reference. Digital peripherals include SMBus/I2C, SPI, two UARTs, a programmable counter/timer array with 6 capture/compare modules, and 64 I/O lines. The microcontroller operates from 3.0V to 3.6V and over a temperature range of -40°C to +85°C. It is available in a 100-pin TQFP package (14x14mm) for surface mount assembly. Typical applications include industrial control, data acquisition, and embedded systems requiring mixed-signal processing.
