This document introduces a small form factor product released by Silicon Laboratories in 2005. The product features 8kB flash, 256-byte SRAM, 10-bit ADC, and 10-bit DAC.
The C8051F330D is a 20‑pin mixed‑signal microcontroller featuring a 25 MIPS 8051 core, 8 kB flash memory, 10‑bit ADC and DAC, and a range of digital peripherals such as UART, SPI, I²C‑compatible SMBus, and multiple timers. It operates from a supply voltage of 2.7 V to 3.6 V and includes on‑chip debug circuitry for full‑speed, non‑intrusive debugging.
Key analog features include a programmable 10‑bit ADC with up to 200 ksps throughput and a current‑mode 10‑bit DAC. The device also provides a comparator with programmable hysteresis, a built‑in temperature sensor, and flexible clock sources that can be switched on‑the‑fly.
