C8051F960-B-GQ

Overview

The C8051F960-B-GQ is an 8-bit microcontroller from Silicon Labs featuring a high-performance 8051 core operating at up to 25 MHz. It integrates 128 kB of flash memory and 8.25 kB of SRAM within a 12x12 mm TQFP-80 package. The device includes a 12-bit, 16-channel ADC with a sampling rate of 75 ksps, two 12-bit DACs, and multiple communication interfaces including SPI, I²C, and UART. It supports a supply voltage range of 2.7 V to 3.6 V and operates between -40°C and +85°C.

Feature Summary

• Ultra-low power architecture optimized for battery-powered applications
• Integrated 12-bit analog-to-digital converter with 16 channels
• On-chip precision analog comparators and digital peripherals

Applications

• Battery-powered metering systems
• Portable medical devices
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm temperature grade and package variant. Ensure compatibility with 2.7V to 3.6V supply rails in final design. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component for designs requiring high-resolution analog acquisition alongside low-power processing. The integrated 12-bit ADC reduces external component count compared to lower-resolution alternatives. Evaluate pin count requirements as the TQFP-80 offers extensive I/O availability for complex peripheral interfacing.

Part Context

This part belongs to the C8051F9xx series of mixed-signal microcontrollers. It shares the 8051 core architecture with other members but distinguishes itself through higher flash capacity and specialized analog features tailored for measurement applications.

Replacement Considerations

Consult official substitution lists for direct equivalents. Verify pinout and register compatibility before replacing with similar 8-bit MCUs.
