8/16 kB ISP FLASH MCU Family C8051F310/1/2/3/4/5 is a high-performance MCU developed by Silicon Laboratories. Its features include 10-bit ADC, comparators, on-chip debug circuit, high clock speed, and large memory.
The C8051F310/1/2/3/4/5 family is a 8051‑compatible microcontroller series featuring a high‑speed CIP‑51 core, on‑chip debug circuitry, and a range of analog and digital peripherals. It supports 2.7 V to 3.6 V supply voltage and includes up to 16 kB of flash memory with in‑system programming capability.
The handbook covers system architecture, memory organization, analog peripherals such as a 10‑bit ADC (up to 200 ksps), comparators, digital interfaces (UART, SMBus, SPI), timer blocks, power‑management modes, package pinouts, and detailed procedures for flash programming, reset handling, and peripheral configuration.
