C8051F311-GMR Description

Short technical summary and product information.

The C8051F311-GMR is a high-performance 8-bit microcontroller based on the 8051 core, manufactured by Silicon Labs. It operates at a maximum speed of 25 MHz, delivering up to 25 MIPS throughput. The device includes 16 KB of in-system programmable Flash memory and 1.25 KB of internal RAM.

 

Analog peripherals include a 10-bit ADC with up to 200 ksps sampling rate and 17 external channels, a built-in temperature sensor, and comparators. Digital peripherals include SMBus (I²C), SPI, UART/USART interfaces, a programmable counter array (PCA) with PWM, and a watchdog timer. The microcontroller has 25 general-purpose I/O pins, all 5V tolerant.

 

Power management is efficient with typical active current of 5 mA at 25 MHz and 0.1 µA in stop mode. The supply voltage range is 2.7V to 3.6V. The device is housed in a 28-VFQFN exposed pad package (28-QFN, 5x5 mm) and is surface mountable. It operates over an industrial temperature range of -40°C to +85°C.
