USB Microcontrollers

Silicon Labs' SiM3U1xx 32-bit USB microcontrollers (MCUs) and C8051F3xx/T62x/T32x 8-bit USB Microcontrollers make it easy to implement industry standard USB connectivity. These devices feature an on-board universal serial bus (USB) 2.0 function controller with an integrated transceiver and on-chip clock recovery, and are available in a wide range of packages. No external resistors, crystal, voltage regulator, EEPROM or other components are required.

Development software is available to provide a complete host and device side software solution. USB class drivers, extensive libraries, example code and development kits all make it easy to add USB to your embedded system.

Customers may use their own vendor ID (VID), or they may use the Silicon Labs VID for USB products. If the Silicon Labs VID is used, the customer must request a unique product ID (PID).
