C8051F968-B-GMR

Overview

The C8051F968-B-GMR is an 8-bit microcontroller from the Silicon Labs C8051F96x series, housed in a 76-VFQFN package. It features 16KB of flash memory and operates at a maximum clock frequency of 24.5 MHz. The device includes 16 ADC channels with 10-bit and 12-bit resolution options. It provides 57 I/O pins and supports supply voltages starting from 1.8 V.

Feature Summary

• Integrates multiple analog-to-digital conversion channels with selectable resolution for precision sensing applications.
• Offers extensive digital connectivity through a high count of general-purpose input/output pins.
• Supports standard serial communication protocols for system integration.

Applications

• Data acquisition systems requiring multi-channel signal monitoring
• Industrial control interfaces with multiple sensor inputs
• Embedded measurement devices utilizing high-resolution ADC capabilities

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet to ensure compatibility with your design requirements. Confirm that the 76-pin QFN package dimensions match your PCB footprint exactly. Check for any recent product change notices regarding assembly or material composition updates before finalizing procurement.

Selection Notes

Select this component when a high pin count and multiple ADC channels are required within an 8-bit architecture. Ensure the 1.8 V minimum supply voltage aligns with your system power rails. Compare the 24.5 MHz speed limit against your processing needs to determine if higher-performance alternatives are necessary.

Part Context

This part belongs to the C8051F9xx family of mixed-signal microcontrollers. These devices combine a standard 8051 core with on-chip peripherals. The C8051F968 variant specifically targets applications needing significant I/O expansion and analog input capacity without moving to a 32-bit processor.

Replacement Considerations

Check for direct cross-references within the C8051F96x series. Verify pinout compatibility if substituting with other 76-pin packages. Review errata sheets for known silicon revisions that may affect performance or functionality.
