C8051F990-C-GMR Description

Short technical summary and product information.

The C8051F990-C-GMR is an 8-bit microcontroller from Silicon Labs based on the high-performance CIP-51 8051 core. It operates at up to 25MHz and includes 8KB of flash program memory and 512 bytes of RAM. The device offers 16 general-purpose I/O pins and integrates peripherals such as brown-out detect/reset, capacitive sensing, programmable counter array (PCA) with PWM, a temperature sensor, and a watchdog timer. It features 9-channel 12-bit analog-to-digital converters and supports SMBus (I²C), SPI, and UART/USART serial interfaces. The operating voltage range is 1.8V to 3.6V, making it suitable for low-power applications. Housed in a compact 20-UFQFN exposed pad package (3x3mm), the microcontroller is designed for surface-mount assembly and operates over a temperature range of -40°C to 85°C.
