C8051F967-B-GM

Overview

The C8051F967-B-GM is an 8-bit microcontroller based on the 8051 core, operating at a maximum frequency of 25 MHz. It integrates 32 KB of FLASH program memory and 8.25 KB of data RAM. The device features a mixed-signal system-on-chip architecture with 16 ADC channels supporting 10-bit and 12-bit resolution. It operates within a supply voltage range of 1.8 V to 3.8 V and is housed in a 40-pin QFN package.

Feature Summary

• Integrates high-resolution analog-to-digital conversion capabilities with multiple input channels for precise signal acquisition.
• Combines digital processing with analog peripherals on a single chip to reduce external component count.
• Utilizes a standard 8051 instruction set architecture for established software compatibility.

Applications

• Data acquisition systems requiring multi-channel sensor interfacing
• Industrial control applications involving analog signal monitoring
• Battery-powered devices utilizing low-voltage operation

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current documentation to confirm pinout and electrical characteristics, as suffixes often denote package variations or temperature grades. Ensure the QFN-40 footprint matches your PCB design constraints. Cross-reference the Mouser number 634-C8051F967-B-GM for accurate sourcing details.

Selection Notes

Select this component when an 8-bit MCU with integrated high-resolution ADCs is required. The 32 KB flash size suits moderate code complexity. Verify that the 1.8 V to 3.8 V supply range aligns with the target system power rails. Consider the 25 MHz clock speed relative to real-time processing requirements.

Part Context

This part belongs to the Silicon Labs C8051F9xx series of mixed-signal microcontrollers. These devices are designed for applications needing both digital control and analog precision. The series typically offers varying amounts of memory and peripheral counts while maintaining a consistent 8051-compatible core architecture.

Replacement Considerations

Check for C8051F967-B-GMR if reel packaging is preferred. Other members of the C8051F96x family may offer different memory sizes but share similar architectures.
