Silicon Labs Microcontrollers C8051F968-A-GQ

The C8051F968-A-GQ is an 8-bit microcontroller from Quarktwin Technology Ltd. featuring a high-speed 8051 core that operates at up to 25 MHz. It includes 16 KB of in-system programmable Flash memory, 256 bytes of SRAM, and 8,092 bytes of XRAM. The microcontroller is designed for ultra-low power consumption, with a low-power active mode drawing 130 ¬µA/MHz and sleep currents as low as 110 nA with data retention. This device integrates a 12-bit, 16-channel analog-to-digital converter (ADC) capable of sampling rates up to 75 ksps in 12-bit mode and 300 ksps in 10-bit mode. It also features an internal temperature sensor, two low-current comparators, and a programmable current reference. The C8051F968-A-GQ supports various digital peripherals, including multiple serial communication interfaces such as SMBus, SPI, and UART. The microcontroller is available in a 80-pin TQFP package and operates within a temperature range of -40 to +85 ¬8C. Its built-in LCD controller supports up to 128 segments, making it suitable for applications requiring display functionality. The device is particularly well-suited for low-power applications, including metering and sensor interfacing, due to its efficient power management features.
