C8051F121-GQ General Description

The C8051F121-GQ is a microcontroller from Silicon Labs' C8051F12x series. It features a high-performance 8051 core with up to 25 MIPS throughput at 25 MHz. The device has 16 KB of flash memory for program storage and 256 bytes of RAM for data storage. It also includes integrated analog peripherals such as an 8-channel 10-bit ADC and a digital-to-analog converter (DAC).The C8051F121-GQ has a wide operating voltage range of 2.7 to 3.6 volts and is available in a 48-pin QFP package. It supports various communication interfaces including UART, SPI, and SMBus/I2C. Other features of this microcontroller include a programmable watchdog timer, brownout detection, and multiple timers/counters for controlling peripherals and generating interrupts.
