C8051F022-GQ

Overview

The C8051F022-GQ is a fully mixed-signal System-on-Chip microcontroller from the Silicon Labs C8051F02x family, featuring a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. Key analog peripherals include a 10-bit SAR ADC with up to 100 ksps throughput, an 8-bit ADC reaching 500 ksps, two 12-bit DACs, and two analog comparators. The device supports a supply voltage range of 2.7V to 3.6V and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a pipelined 8051 microcontroller core capable of executing 70% of instructions in one or two system clocks for high processing efficiency.
• Features dual analog-to-digital converters, including a 10-bit SAR ADC with programmable gain and an 8-bit ADC with high-speed throughput capabilities.
• Includes on-chip JTAG debug circuitry supporting full-speed, non-intrusive in-circuit debugging with breakpoints and single-stepping functionality.
• Provides comprehensive digital peripheral interfaces such as hardware SMBus, SPI, and two concurrent UART serial ports alongside multiple timer arrays.

Applications

• Data acquisition systems requiring simultaneous analog signal processing and digital control
• Industrial process control applications utilizing precision monitoring and feedback loops
• Embedded sensor interface designs leveraging integrated comparators and programmable amplifiers

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin alignment prior to installation. Ensure compatibility with existing design constraints regarding operating voltage and thermal management. Review end-of-life status documentation if sourcing from secondary markets to guarantee long-term availability and support continuity.

Selection Notes

Select this component when a fully mixed-signal solution is required without external analog components. Consider the specific ADC resolution requirements, noting that this variant utilizes a 10-bit converter unlike the 12-bit version in the same family. Evaluate memory needs against the fixed 64 kB Flash capacity. Verify that the 64-pin TQFP package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the C8051F02x series of fully mixed-signal microcontrollers. It shares architectural similarities with the C8051F020, F021, and F023 variants, differing primarily in ADC resolution and port configurations. The series is characterized by its monolithic integration of digital and analog functions on a single silicon die, reducing board space and component count.
