C8051F980-GMR

Overview

The C8051F980-GMR is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, utilizing the CIP-51 core. It features 8KB of in-system programmable Flash memory and 512 bytes of RAM. The device operates at a maximum clock speed of 25MHz with an internal oscillator. It includes nine 12-bit analog-to-digital converters (ADCs). Power supply voltage ranges from 1.8V to 3.6V. Connectivity options include SMBus/I²C, SPI, and UART/USART interfaces. The component is housed in a 20-QFN package measuring 3x3mm.

Feature Summary

• Integrates nine 12-bit ADCs for high-resolution analog signal acquisition.

Applications

• Battery-powered sensor nodes requiring low power consumption.

Procurement Notes

Verify the specific suffix against official documentation, as variations may exist between GMR and other packaging codes. Confirm current production status, as this part number has been marked obsolete in multiple distributor records. Ensure compatibility with existing firmware before procurement.

Selection Notes

Select this component when a compact 8-bit MCU with integrated high-resolution analog conversion is required. It serves as a suitable alternative to variants like the C8051F981-C-GMR if ADC functionality is necessary. Consider the 20-QFN footprint constraints during PCB layout design.

Part Context

This unit belongs to the C8051F9xx family of mixed-signal microcontrollers. These devices are designed for applications demanding precise analog control within a small form factor. The C8051F980 variant specifically targets systems needing multiple analog inputs without external components.
