C8051F353 is a 50 MIPS, 8 kB Flash, 16-Bit ADC, 28-Pin Mixed-Signal MCU.
The C8051F353 is a 28‑pin mixed‑signal microcontroller from Silicon Labs featuring a high‑speed 8051 core, up to 50 MIPS performance, 8 kB flash memory and a 16‑bit ADC with programmable gain. It includes on‑chip debug, multiple digital peripherals (UART, SPI, SMBus/I²C) and a flexible clock system with internal and external sources.
Key specifications include a supply voltage range of 2.7 V to 3.6 V, typical operating current of 17 mA at 50 MHz, and a temperature range of –40 °C to +85 °C. The ADC offers 16‑bit resolution with ±15 ppm INL and 110 dB CMRR, while the DACs provide 8‑bit resolution. The device is supplied in a lead‑free 28‑pin QFN package.
