C8051F321 8051 8-bit Microcontroller, 25 MHz, 16 Flash(kB)

The C8051F321 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 25 MHz performance along with 16 kB Flash, 2.25 kB RAM. On-chip analog features include a 10-bit, 13-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, QFN28, the C8051F321 provides a truly single-chip solution for embedded USB applications.
