C8051F972-A-GM Description

Short technical summary and product information.

The C8051F972-A-GM is an 8-bit microcontroller based on the CIP-51 core from Silicon Labs. It features 32KB of Flash program memory and 8KB of RAM, making it suitable for embedded control applications. The device operates at a maximum speed of 25MHz and includes 19 general-purpose I/O pins. Connectivity options include I²C/SMBus, I²C Slave, SPI, and UART/USART interfaces. Peripherals include CapSense, DMA, POR, PWM, and WDT. The microcontroller operates from a supply voltage of 1.8V to 3.6V and has an internal oscillator. It is housed in a 24-WFQFN exposed pad package (24-QFN 4x4mm) for surface mount assembly. The operating temperature range is -40°C to 85°C. The device includes a 19-channel 10-bit A/D converter for analog signal acquisition. The CIP-51 core is pipelined for efficient execution. The integrated CapSense peripheral enables capacitive touch sensing. The DMA controller allows data transfers without CPU intervention. The PWM module is useful for motor control and power conversion.
