C8051F32x/34x USB Microcontrollers

Silicon Lab​s' USB Microcontrollers (MCUs), with embedded full-speed USB 2.0, make it easy to implement industry standard USB connectivity. USBXpress development software is available to provide a complete host and device side software solution.

The USB MCUs feature an on-board universal serial bus (USB) 2.0 function controller with an integrated transceiver and on-chip clock recovery. No external resistors, crystal, voltage regulator, EEPROM or other components are required. On-chip resources include a high-speed 8051 CPU with up to 64 kB Flash, UARTs, SMBus, SPI, timers, counters and PWM generators. On-chip analog features include a multi-channel 10-bit ADC, voltage reference, internal oscillator, comparators and a temperature sensor. Available in 28-pin QFN, 32-pin LQFP or 48-pin TQFP packages, these devices provide a single-chip solution for embedded USB applications.
