C8051F231-GQR Description

Short technical summary and product information.

The C8051F231-GQR is an 8-bit microcontroller from Silicon Labs, featuring a high-performance 8051 core operating at 25 MHz. It includes 8 KB of Flash program memory and 256 bytes of RAM, suitable for embedded control applications requiring moderate code and data storage.

 

The device offers a range of integrated peripherals including brown-out detect/reset, power-on reset (POR), and watchdog timer (WDT). It provides 22 general-purpose I/O pins and supports serial communication via SPI and UART/USART interfaces. The operating voltage range is 2.7V to 3.6V, and it includes an internal oscillator, eliminating the need for external clock components.

 

The microcontroller is housed in a 32-LQFP package with a 7x7 mm body, designed for surface mount assembly. It operates over an industrial temperature range of -40°C to 85°C, making it suitable for demanding environments. With its 8-bit architecture and peripheral set, it is well-suited for sensor interfacing, motor control, and other embedded control tasks.
