C8051F980-C-GMR

Overview

The C8051F980-C-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), SMBus/I²C, SPI, and UART/USART interfaces. Power supply ranges from 1.8V to 3.6V, and it functions within -40°C to 85°C temperature limits in a 20-QFN package.

Feature Summary

Integrates nine 12-bit ADCs for high-resolution analog signal acquisition.
Includes on-chip temperature sensor and power-on reset circuitry.
Supports multiple communication protocols including I²C, SPI, and UART.
Features in-system programmable Flash for flexible code storage.

Applications

Battery-powered sensor nodes requiring low voltage operation
Industrial control systems with analog input requirements
Data acquisition modules using integrated ADCs
Temperature monitoring applications leveraging internal sensors

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as moisture sensitivity may affect performance if packaging is compromised. Check revision status against official errata documents before integration into final designs.

Selection Notes

Select this MCU when nine 12-bit ADCs are necessary within an 8-bit architecture. Consider the 1.8V minimum supply voltage for battery applications. Evaluate pin count constraints due to the 20-QFN form factor. Ensure software tools support the CIP-51 core for development compatibility.

Part Context

This component belongs to the C8051F9xx family of mixed-signal microcontrollers. It shares architectural similarities with other members like the C8051F990 but differs in peripheral configuration. The series emphasizes high integration levels suitable for compact embedded designs.
