C8051F015-GQR

Overview

The C8051F015-GQR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F0xx family, featuring a high-speed CIP-51 core operating at up to 25 MIPS. It integrates 32 KB of in-system programmable flash memory and 2304 bytes of internal SRAM. The device includes a 10-bit SAR ADC with up to 8 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, housed in a 64-pin TQFP package.

Feature Summary

• Integrated JTAG debug circuitry enables full-speed, non-intrusive in-system debugging without external emulation hardware.
• Features a pipelined instruction architecture that executes 70% of the instruction set in one or two system clocks for high throughput.
• Includes a precision voltage reference and VDD monitor/brown-out detector for stable operation under varying power conditions.

Applications

• Portable battery-powered devices requiring low power consumption
• Industrial control systems utilizing analog signal processing
• Data acquisition systems employing the integrated SAR ADC

Procurement Notes

Verify component authenticity through authorized distributors. Confirm the datasheet revision matches the production batch. Check for end-of-life status as this part may be discontinued. Ensure ESD handling protocols are followed during storage and assembly. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this MCU for applications needing mixed-signal capabilities alongside an 8051-compatible core. Consider the 10-bit ADC resolution and 2304-byte RAM size against project requirements. Evaluate the 64-pin TQFP package constraints for board layout. Compare performance metrics with newer Silicon Labs alternatives if new designs are required.

Part Context

This component belongs to the C8051F0xx mixed-signal MCU family, which combines a high-speed 8051 core with extensive on-chip peripherals. The family is designed for cost-sensitive embedded applications requiring precise analog control and digital processing. The GQR suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

Replacement Considerations

Check for official Silicon Labs recommended replacements due to potential discontinuation. Verify pin-to-pin compatibility and register mapping equivalence. Assess firmware portability between the legacy C8051F series and modern EFM8 or C8051F3xx families.
