Silicon Labs C8051F320/1 MCU Family Manual
The C8051F320/1 family is a full‑speed USB microcontroller with a 10‑bit ADC, two comparators, internal voltage reference, POR/brown‑out detector, and a range of digital peripherals including UART, SPI, SMBus, and a programmable counter array. It supports USB 2.0 full‑speed (12 Mbps) or low‑speed (1.5 Mbps) operation with an integrated transceiver and 1 kB USB buffer.
The device includes 2304 bytes of internal RAM, 16 kB of flash memory programmable in‑system, and a voltage regulator that operates from 4.0 V to 5.25 V. Packages are offered in 32‑pin LQFP and 28‑pin QFN, and on‑chip debug circuitry provides breakpoints, single‑stepping, and memory inspection without an external emulator. Contact information and legal notices are provided at the end of the document.
