C8051F962-B-GQR Description

Short technical summary and product information.

The C8051F962-B-GQR is an ultra low power 8-bit microcontroller from Silicon Labs, based on the 8051 core. It operates at up to 25 MHz and features 128KB of Flash program memory and 8.25KB of internal data RAM. The device includes 57 general-purpose I/O pins, all 5V tolerant, and supports connectivity via I2C, SPI, and UART/USART interfaces.

 

Key analog peripherals include a 12-bit ADC with 16 channels (up to 75 ksps in 12-bit mode or 300 ksps in 10-bit mode), two low-power comparators, and an integrated temperature sensor. The MCU also features a hardware AES encryption engine, DMA controller, and CRC for data processing acceleration. An integrated LCD controller supports up to 128 segments (32x4).

 

The device is designed for ultra low power consumption, with active current of 130 µA/MHz (dc-dc enabled) and sleep currents as low as 120 nA with data retention. It includes a dc-dc buck converter for dynamic voltage scaling, a SmaRTClock oscillator, and multiple sleep modes. The package is 80-TQFP (12x12mm) surface mount, rated for -40°C to 85°C operation.
