C8051F320-GQR

C8051F320-GQR 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 25MHz performance along with 16KB flash, 2.25KB RAM. On-chip analogue features include a 10-bit, 17-channel, 200Ksps ADC, voltage reference, a ±1.5 internal oscillator, 2 comparators, and a temperature sensor. Integrating additional communication interfaces along with rich analogue in a 7x7 mm, QFP32 package, this provides a truly single-chip solution for embedded USB applications.

• VREF from external pin, internal reference, or VDD, built-in temperature sensor
• Two comparators, internal voltage reference, POR/brown-out detector
• USB specification 2.0 compliant, supports eight flexible endpoints
• On-chip debug circuitry facilitates full speed, non-intrusive in-system debug (no emulator required)
• Voltage regulator input is 4.0 to 5.25V
• Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
• Hardware enhanced SPI™, enhanced UART, and SMBus™ serial ports
• External oscillator: Crystal, RC, C, or Clock (1 or 2 pin modes)
• Can switch between clock sources on-the-fly; useful in power-saving strategies
• LQFP-32 package, temperature rating range from -40 to +85°C
