C8051F343-GM

C8051F32x/34x USB Microcontrollers

The C8051F343-GM microcontroller (MCU) features an on-board universal serial bus (USB) 2.0 function controller with an integrated transceiver and on-chip clock recovery. No external resistors, crystal, voltage regulator, EEPROM, or other components are required for USB applications. The MCU includes a powerful 8051 core with 50 MHz performance along with 32 kB Flash, 2.25 kB RAM. On-chip analog features include a 10-bit, 21-ch., 200 ksps ADC, voltage reference, a ±1.5 internal oscillator, 2 comparators, and a temperature sensor. Integrating additional communication interfaces along with rich analog in a 5x5 mm, QFN32, the C8051F343-GM provides a truly single-chip solution for embedded USB applications.
