C8051F963-B-GM

Overview

The C8051F963-B-GM is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, utilizing the CIP-51 core. It features 128KB of FLASH program memory and 8.25KB of RAM. The device operates on a supply voltage range of 1.8V to 3.8V with an internal oscillator supporting speeds up to 25MHz. It integrates 16 channels of 10-bit/12-bit ADCs and supports SMBus, SPI, and UART communication interfaces. The component is housed in a 40-WFQFN package.

Feature Summary

• Integrates high-resolution analog-to-digital conversion capabilities with multiple configurable channels for precision signal acquisition.
• Combines extensive non-volatile program storage with substantial data memory to support complex embedded applications.
• Includes comprehensive digital peripheral sets such as timers, counters, and standard serial communication interfaces.

Applications

• Industrial control systems requiring precise analog monitoring
• IoT sensor nodes with low power constraints
• Consumer electronics devices needing integrated LCD driving capabilities

Procurement Notes

Verify the specific revision suffix (B) against current Silicon Labs documentation to ensure compatibility with required errata updates. Confirm that the 40-QFN package dimensions match the target PCB footprint exactly. Check for any recent Product Change Notifications regarding pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when an 8-bit architecture suffices but high channel count ADC resolution is critical. Ensure the design accommodates the 1.8V to 3.8V operating range. Consider the 40-pin form factor for board space constraints compared to smaller MCU options in the same family.

Part Context

This part belongs to the C8051F9xx Ultra Low Power LCD MCU Family. It shares architectural similarities with other members like the C8051F965, differing primarily in memory size and peripheral configuration. The series targets battery-powered applications requiring mixed-signal processing capabilities within a compact footprint.

Replacement Considerations

Direct substitutes include other C8051F9xx variants with compatible pinouts, such as the C8051F965-B-GM, provided memory requirements are met. Verify software compatibility if migrating between different memory capacities within the same silicon generation.
