C8051F001-GQR

Overview

The C8051F001-GQR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F0xx family, featuring a pipelined CIP-51 CPU core with up to 25 MIPS throughput at a 25 MHz clock. It integrates 32 KB of in-system programmable (ISP) Flash memory and 256 bytes of internal SRAM. The device includes a 12-bit SAR ADC with up to eight external inputs, two 12-bit DACs, and two analog comparators. Communication interfaces include hardware SMBus, SPI, and UART. It operates on a supply voltage of 2.7V to 3.6V within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated high-speed 8051-compatible CPU core capable of executing 70% of instructions in one or two system clocks for efficient processing.
• On-chip JTAG debug circuitry enabling full-speed, non-intrusive in-system debugging without requiring external emulation hardware.
• Comprehensive analog peripheral suite including a 12-bit ADC with programmable gain amplifier, dual 12-bit DACs, and precision voltage reference.

Applications

• Data acquisition systems requiring precise analog-to-digital conversion
• Industrial control applications utilizing multiple serial communication protocols
• Battery-powered devices leveraging low-power sleep modes

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Check revision markings against official datasheets to ensure compatibility with existing firmware and hardware designs.

Selection Notes

Select this component when a fully integrated mixed-signal solution is required to minimize external components. Consider the 256-byte RAM limitation for complex algorithms. Evaluate the 12-bit ADC resolution against application requirements compared to 10-bit variants in the same family.

Part Context

This part belongs to the C8051F0xx series of mixed-signal MCUs, which are known for their complete integration of digital and analog peripherals on a single chip. The GQR suffix indicates a specific tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Consult the official product selection guide for pin-compatible alternatives within the C8051F0xx family. Verify that substitute parts maintain identical Flash size, RAM capacity, and peripheral configurations before implementation.
