C8051F126-GQ Description

Short technical summary and product information.

The C8051F126-GQ is a high-performance 8-bit microcontroller from Silicon Labs based on the 8051 core. It features 128KB of Flash program memory and 8.25KB of internal data RAM, with a maximum clock speed of 50MHz. The device includes a rich set of peripherals such as multiple ADC and DAC converters, SMBus/I2C, SPI, and UART serial interfaces, as well as 64 general-purpose I/O pins. It also integrates a brown-out detect/reset, power-on reset, PWM, temperature sensor, and watchdog timer.

 

The microcontroller operates from a 2.7V to 3.6V supply and is rated for industrial temperature range from -40°C to +85°C. It is housed in a 100-pin TQFP package (14x14mm) for surface mount assembly. The internal oscillator eliminates the need for external clock components. This microcontroller is suitable for embedded control applications requiring high integration and low power consumption.
