This document introduces the C8051F30x series of mixed-signal ISP Flash MCUs, which feature an 8-bit ADC, comparator, debug functionality, etc. They are suitable for various application scenarios.
The C8051F30x family combines a high‑speed 8051‑compatible core with a rich set of analog and digital peripherals. It includes an 8‑bit ADC (F300/2 only) up to 500 ksps, a 10‑bit ADC at 200 ksps, programmable amplifiers, temperature sensor, voltage comparator, UART, SMBus, and a programmable counter array. The devices operate from 2.7 V to 3.6 V and support in‑system programming via ISP flash.
The handbook describes the on‑chip debug circuitry, power‑management modes (idle, stop), flash programming procedures, oscillator options, and peripheral configuration. It also provides pin‑out and package information, electrical characteristics, and contact details for Silicon Laboratories support.
