C8051F980-C-GM

Overview

The C8051F980-C-GM 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). Connectivity options consist of SMBus/I²C, SPI, and UART/USART interfaces. The unit supports 16 general-purpose I/O pins and integrates peripherals such as PWM, a temperature sensor, and watchdog timer. Operating voltage ranges from 1.8V to 3.6V within a -40°C to 85°C temperature range, housed 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 serial communication protocols including SPI and I²C.

Applications

• Battery-powered sensor nodes requiring low voltage operation
• Industrial control systems with analog input requirements
• Data acquisition modules using integrated ADCs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and check for relevant compliance certifications such as RoHS. Review official errata sheets for known silicon revisions prior to integration. Ensure supply chain stability as availability status may vary by region.

Selection Notes

Select this component when nine independent 12-bit ADC channels are required within a compact 20-pin footprint. It is suitable for designs needing 1.8V to 3.6V operation without external level shifters. Consider alternative pin counts if more than sixteen GPIOs are necessary.

Part Context

This part belongs to the C8051F9xx family of fully integrated mixed-signal microcontrollers. It shares architectural similarities with other members like the C8051F989 but offers specific memory and peripheral configurations tailored for cost-sensitive embedded applications.
