C8051F011-GQ

Overview

The C8051F011-GQ is a mixed-signal System-on-Chip microcontroller from the Silicon Labs C8051F0xx family. It features a high-speed 8051 CPU core with up to 25 MIPS throughput at 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 10-bit SAR ADC, two 12-bit DACs, two analog comparators, and a precision voltage reference. Digital interfaces comprise hardware SMBus, SPI, and UART ports. The component 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

• Integrated on-chip JTAG debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulation hardware.
• High-performance pipelined 8051 architecture executing 70% of the instruction set in one or two system clocks.
• Comprehensive analog subsystem featuring a 10-bit ADC with programmable gain amplifier and data-dependent windowed interrupt generator.
• Flexible digital I/O configuration via a programmable crossbar allowing dynamic assignment of peripheral signals to pins.

Applications

• Industrial process control systems requiring precise analog signal acquisition
• Battery-powered instrumentation utilizing low-power sleep modes
• Data acquisition modules integrating simultaneous digital and analog processing

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt, as the TQFP form factor requires careful handling during surface-mount assembly. Ensure design compliance with the specified 2.7 V to 3.6 V operating voltage limits. Review the datasheet for absolute maximum ratings to prevent damage during soldering or operation. Note that this specific part number may be subject to lifecycle status changes.

Selection Notes

Select this component when a complete mixed-signal solution is required without external ADCs or DACs. The 256-byte RAM limit necessitates evaluation against application stack requirements. Consider the 10-bit ADC resolution if higher precision is needed, as other family members offer 12-bit variants. Verify pin count compatibility with the target PCB layout, specifically for the 64-pin TQFP option.

Part Context

This microcontroller belongs to the C8051F0xx series, which provides fully integrated mixed-signal capabilities on a single chip. The family shares a common CIP-51 CPU core and peripheral set, differing primarily in memory sizes and ADC resolutions. The C8051F011 variant specifically targets applications balancing moderate code storage needs with versatile analog interface requirements.

Replacement Considerations

C8051F010-GQ: Identical specifications except for reduced RAM size.

FAQ
