Product Information

Back to top
The C8051F340-GQ 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 64 kB Flash, 4.25 kB RAM. On-chip analog features include a 10-bit, 20-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 7x7 mm, QFP48, the C8051F340-GQ provides a truly single-chip solution for embedded USB applications.

Symmetry Electronics is an authorized Silicon Labs distributor.
