C8051F326

C8051F32x/34x USB Microcontrollers

The C8051F326 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 25 MHz performance along with 16 kB Flash, 1.5 kB RAM. On-chip analog features include a — ADC, voltage reference, a ±1.5 internal oscillator, 0 comparators, and a temperature sensor. Integrating additional communication interfaces along with rich analog in a 5x5 mm, QFN28, the C8051F326 provides a truly single-chip solution for embedded USB applications.
