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 family is ideal for applications requiring cost effective, 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.
The C8051F38x family is pin and code compatible with the existing C8051F34x family, providing a seamless migration path for enhanced performance and additional features.
