C8051F969-B-GM

Overview

The C8051F969-B-GM is an 8-bit microcontroller from the Silicon Labs C8051F96x series, utilizing a CIP-51 8051 core. It features 64 kB of in-system programmable Flash memory and 8.25 kB of RAM. The device operates at a maximum clock frequency of 25 MHz with a supply voltage range of 1.8 V to 3.8 V. It includes a 16-channel ADC with 10-bit or 12-bit resolution, four timers/counters, and interfaces such as I2C, SPI, and UART. The component is housed in a TQFP-80 package.

Feature Summary

• Integrates a high-speed 8051 CPU with up to 25 MIPS performance.
• Includes on-chip analog peripherals like a multi-channel ADC and comparators.
• Supports in-system programming via standard debug interfaces.

Applications

• Industrial control systems requiring analog signal processing
• Embedded sensor nodes with multiple input channels
• Data acquisition modules using internal ADC capabilities

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Confirm current availability status as many devices in this family are discontinued. Ensure compatibility with existing PCB footprints for the TQFP-80 form factor before procurement.

Selection Notes

Select this part when a balance of moderate Flash capacity and extensive analog inputs is required. The 16-channel ADC makes it suitable for applications needing multiple sensor readings without external multiplexers. Verify that the 25 MHz speed meets real-time processing requirements.

Part Context

This component belongs to the C8051F96x series, which focuses on mixed-signal applications. It shares architectural similarities with other members of the F9xx family but offers specific memory and peripheral configurations tailored for cost-sensitive embedded designs.

Replacement Considerations
