C8051F350-GQR

The Silicon Labs C8051F350-GQR is a high-performance 8-bit microcontroller built around the 8051 core. It operates at up to 50 MIPS throughput and includes 8 kB of in-system programmable Flash memory and 768 bytes of RAM. The device integrates a versatile set of analog peripherals, including a 24/16-bit delta-sigma ADC with an 8-input multiplexer and programmable gain amplifier (1x to 128x), two 8-bit current output DACs, and a built-in temperature sensor. The ADC supports conversion rates up to 1 ksps and offers selectable resolution for precision measurement applications. Power consumption is optimized with typical active current of 5.8 mA at 25 MHz and stop mode current of just 0.1 µA, making it suitable for battery-powered designs. The microcontroller provides 17 multifunctional I/O pins capable of 5 V tolerance, along with serial interfaces including SMBus (I2C), SPI, and UART/USART. Additional peripherals include a power-on reset (POR), programmable counter array (PCA) with PWM, watchdog timer (WDT), and flexible clock sources including an internal 24.5 MHz oscillator. The device is housed in a 32-lead LQFP package measuring 7x7 mm and operates over a temperature range of -40°C to 85°C with a supply voltage of 2.7 V to 3.6 V. This combination of features makes it ideal for industrial control, sensor interfacing, and data acquisition systems.
