C8051F127-GQR Description

Short technical summary and product information.

The C8051F127-GQR is a high-performance 8-bit microcontroller based on the 8051 core, manufactured by Silicon Laboratories. It operates at a maximum speed of 50MHz and features 128KB of Flash program memory and 8.25KB of internal data RAM. The device includes a rich set of analog peripherals: an 8-bit ADC with 8 inputs, a 10-bit ADC with 8 inputs, and two 12-bit DACs. It also integrates a temperature sensor, brown-out detect/reset, power-on reset, PWM, and watchdog timer. For connectivity, it supports EBI/EMI, SMBus (I2C), SPI, and two UART/USART interfaces. The microcontroller is housed in a 64-pin TQFP package (10x10mm) with surface mount mounting. It operates over a supply voltage range of 2.7V to 3.6V and a temperature range of -40°C to +85°C. The internal oscillator eliminates the need for external clock components. This MCU is suitable for embedded control applications requiring mixed-signal processing and multiple communication interfaces.
