C8051F011-GQR

Overview

The C8051F011-GQR is a mixed-signal System-on-Chip microcontroller from the Silicon Labs C8051F0xx family. It integrates a high-speed 8051-compatible CPU capable of up to 25 MIPS, 32 KB of in-system programmable Flash memory, and 256 bytes of internal SRAM. The device features a 10-bit SAR ADC with up to eight external inputs, two 12-bit DACs, two analog comparators, and an on-chip voltage reference. Digital peripherals include hardware SMBus, SPI, and UART interfaces, alongside four general-purpose 16-bit timers and a Programmable Counter Array. It operates within a supply voltage range of 2.7 V to 3.6 V and supports temperatures from -40°C to +85°C.

Feature Summary

• Integrates a pipelined 8051 core executing instructions in one or two system clocks for high throughput.
• Includes a 10-bit successive approximation ADC with programmable gain amplifier and windowed interrupt generator.
• Features dual 12-bit digital-to-analog converters and two analog comparators with configurable hysteresis.
• Provides full-speed non-intrusive in-system debugging via on-chip JTAG circuitry without requiring external emulation hardware.

Applications

• Industrial process control systems
• Medical instrumentation
• Data acquisition modules
• Battery-powered measurement devices

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt. Review the official datasheet for absolute maximum ratings and thermal handling requirements before integration. Ensure design compliance with RoHS directives. Note that this specific part number may be subject to end-of-life status; consult current manufacturer documentation for availability and lifecycle updates.

Selection Notes

Select this component when a fully integrated mixed-signal solution is required to minimize board space. It is suitable for applications needing simultaneous analog conversion and digital communication. Consider the 256-byte RAM limitation for complex software architectures. Verify that the 2.7V to 3.6V operating voltage aligns with the target power supply rails. Evaluate the pin count and peripheral availability against specific interface requirements.

Part Context

This device belongs to the C8051F0xx series of mixed-signal microcontrollers. It shares architectural similarities with the C8051F00x and C8051F01x families but is distinguished by its specific memory configuration and 10-bit ADC resolution. The GQR suffix indicates a 64-pin TQFP package variant. It represents a cost-effective alternative to discrete MCU and ADC combinations in embedded designs.

Replacement Considerations

Consult the manufacturer's product selection guide for direct functional equivalents within the C8051F0xx family. Verify pin compatibility and peripheral overlap before substitution. Check for updated revisions or successor models if the current part is discontinued.
