C8051F022-GQR

Overview

The C8051F022-GQR is a mixed-signal System-on-Chip microcontroller from the Silicon Labs C8051F02x family, featuring a high-speed 8051 core operating at up to 25 MHz. It integrates 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. The device includes a 10-bit SAR ADC with programmable throughput up to 100 ksps, two 12-bit DACs, and two analog comparators. Digital peripherals include hardware SMBus, SPI, and dual UARTs. It operates on a supply voltage of 2.7V to 3.6V within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated 10-bit SAR ADC with programmable gain amplifier and windowed interrupt generator
• Dual 12-bit DACs capable of timer-synchronized jitter-free waveform generation
• On-chip JTAG debug circuitry supporting full-speed non-intrusive in-circuit debugging
• Hardware serial interfaces including SMBus, SPI, and two concurrent UART ports

Applications

• Data acquisition systems requiring mixed-signal processing
• Industrial control applications utilizing analog sensor inputs
• Embedded systems needing in-system programmable Flash for field upgrades
• Precision measurement devices leveraging integrated voltage references and comparators

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against TQFP-64 specifications. Ensure compliance with RoHS directives and check for specific environmental certifications required by your region. Validate that the revision level matches your design documentation requirements.

Selection Notes

Select this component when a complete mixed-signal solution is required without external ADC/DAC chips. The 10-bit resolution suits moderate precision applications compared to the 12-bit variants in the same family. Consider the 64-pin TQFP package constraints for PCB layout. Evaluate power consumption profiles across different clock speeds and sleep modes for battery-operated designs.

Part Context

This part belongs to the C8051F02x series of fully integrated mixed-signal microcontrollers. It shares the same core architecture and digital peripherals as the C8051F020, F021, and F023, differing primarily in ADC resolution and port configurations. The GQR suffix indicates a Green (RoHS compliant) TQFP-64 package variant suitable for surface-mount assembly processes.

Replacement Considerations

Direct functional substitutes within the same family include C8051F020-GQR, C8051F021-GQR, and C8051F023-GQR. Note that these alternatives offer 12-bit ADC resolution instead of 10-bit. Verify pin compatibility and software register mapping before migration.
