C8051F002-GQR

Overview

The C8051F002-GQR is a mixed-signal System-on-Chip microcontroller from the Silicon Labs C8051F0xx family. It features a high-speed 8051-compatible CPU core operating at up to 25 MIPS with a 25 MHz clock frequency. The device integrates 32 KB of in-system programmable (ISP) Flash memory and 256 bytes of internal SRAM. Key analog peripherals include a 12-bit SAR ADC, two 12-bit DACs, and two analog comparators. Digital interfaces encompass SMBus, SPI, and UART serial ports. The unit operates within a supply voltage range of 2.7 V to 3.6 V and supports an industrial temperature range of –40°C to +85°C.

Feature Summary

• Integrates a high-speed pipelined 8051 CPU core capable of executing 70% of the instruction set in one or two system clocks for efficient processing throughput.
• Includes on-chip JTAG debug circuitry that facilitates full-speed, non-intrusive in-system debugging without requiring external emulation hardware.
• Features a complete mixed-signal peripheral suite including a 12-bit ADC with programmable gain amplifier, dual 12-bit DACs, and analog comparators with configurable hysteresis.
• Provides flexible digital I/O via a programmable crossbar that allows mapping of standard peripherals such as SMBus, SPI, and UART to available pins.

Applications

• Data acquisition systems utilizing the integrated 12-bit ADC and precision voltage reference.
• Embedded control applications requiring simultaneous serial communication via SMBus, SPI, and UART.
• Battery-powered devices leveraging multiple power-saving sleep and shutdown modes.
• Industrial monitoring circuits employing the built-in temperature sensor and voltage comparators.

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin alignment prior to installation. Ensure design compliance with absolute maximum ratings regarding supply voltage and temperature limits. Review the specific revision of the datasheet for any updates to electrical characteristics or register definitions before finalizing production integration.

Selection Notes

Select this component when a fully integrated mixed-signal solution is required to minimize external component count. The inclusion of ISP Flash allows for field updates without specialized programming hardware. Consider the 256-byte RAM limitation for complex software architectures. Evaluate the 12-bit ADC resolution against application signal requirements. Verify that the 64-pin TQFP package fits the target PCB layout constraints.

Part Context

This part belongs to the C8051F0xx mixed-signal MCU family, which combines a fast 8051 core with extensive on-chip analog and digital peripherals. The family is designed to reduce board space and cost by integrating functions typically found in discrete designs. The C8051F002 variant specifically offers 32 KB of Flash and 256 bytes of RAM, distinguishing it from other members with larger memory capacities.

Replacement Considerations

Consult the manufacturer's product selection guide for direct functional equivalents within the same family. Verify pin compatibility and memory size differences when substituting with other C8051F variants. Check for updated documentation regarding end-of-life status or recommended design alternatives if current stock is limited.
