C8051F388-B-GQ Product Details

Silicon Labs' USB microcontrollers (MCUs), with embedded full-speed USB 2.0, offer best-in-class analog peripherals with a high performance CPU. In addition, USBXpress development kits are available to provide a complete host and device software solution.

The C8051F38x microcontroller (MCU) family is ideal for applications requiring cost effective, robust analog and digital peripherals, and high performance processing capabilities. This family of MCUs provide solutions for both USB-based applications and broad-based applications that do not require USB. 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, and temperature sensor.
