C8051T62x/T32x USB Microcontrollers

Silicon Labs' USB Microcontrollers (MCUs), contain an embedded full-speed USB 2.0, best-in class analog peripherals and a high performance CPU. In addition, USBXpress development kits are available to provide a complete host and device software solution.
The C8051T62x/T32x EPROM-based memory family is ideal for cost-sensitive applications requiring robust analog and digital peripherals and high performance processing capabilities. The USB MCUs feature an on-board, fully integrated universal serial bus (USB) 2.0, function controller and transceiver. No external resistors, crystal or voltage regulator are required. Best-in-class, on-chip analog peripherals include a multi-channel high performance ADC up to 500 Ksps, comparators and internal voltage reference (non-ADC versions are also available).
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.
