C8051F32x/34x Microcontollers with USB, Silicon Labs

The Silicon Labs C8051F32x/34x families of microcontrollers (MCU) are embedded with full-speed USB 2.0, simplifying the implemention of USB into your design. Their USBXpress software enables a complete host and device side solution. No external resistors, crystal, voltage regulator, EEPROM or other components are required.

This family of microcontrollers includes a high-speed 8051 CPU with between 16 kB and 64 kB Flash. Together with UARTs, SMBus, SPI, timers, counters, PWM generators, multi-channel 10-bit ADC, voltage reference, internal oscillator, comparators and temperature sensor.

They are specified for 2.7 V to 3.6 V operation over the industrial temperature range (-45°C to +85°C). Available in 28-pin QFN, 32-pin LQFP or 48-pin TQFP packages.
