This document describes the features and characteristics of the Small Form Factor product introduced by Silicon Laboratories in 2005. The product is a mixed-signal MCU with 25 MIPS processing power, 4 kB flash, and 256 bytes of SRAM. It also includes features such as a comparator, power-on reset/brown-out detector, and on-chip debug circuitry. The product is suitable for low-power and small-size applications.
The C8051F304 is an 11‑pin mixed‑signal microcontroller featuring a high‑speed 8051‑core capable of up to 25 MIPS at 25 MHz, 4 kB Flash, 256 bytes of data RAM, and a range of analog and digital peripherals such as comparators, programmable timers, and an on‑chip debugger. It operates from 2.7 V to 3.6 V and supports a temperature range of –40 °C to +85 °C.
The device is offered in a standard 11‑pin MLP package and a lead‑free variant (C8051F304‑GM). Electrical specifications include a typical operating current of 5.8 mA at 25 MHz and a shutdown current below 0.1 pA. Detailed pin‑out and package drawings are provided for hardware designers.
