C8051F064-GQ

Overview

The C8051F064-GQ is an 8-bit microcontroller from the Silicon Labs C8051F06x family, featuring a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz clock. It includes 64 kB of in-system programmable Flash memory and 4352 bytes of internal data RAM. Key analog peripherals consist of two 16-bit SAR ADCs with up to 1 Msps throughput and three analog comparators. The device supports a 100-pin TQFP package, operates within a supply voltage range of 2.7 V to 3.6 V, and functions across a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated dual 16-bit SAR ADCs with direct memory access for high-speed data acquisition without software overhead
• On-chip JTAG debug circuitry enabling full-speed, non-intrusive in-circuit debugging with breakpoints and watchpoints
• Pipelined instruction architecture executing 70% of the instruction set in one or two system clocks
• Hardware support for SMBus, SPI, and multiple UART serial ports available concurrently

Applications

• High-precision data acquisition systems requiring simultaneous multi-channel sampling
• Industrial control applications utilizing CAN bus communication
• Embedded systems needing on-chip debugging capabilities
• Signal processing tasks involving windowed interrupt generation

Procurement Notes

Verify the specific suffix GQ corresponds to the 100-pin TQFP package variant. Confirm that the component meets RoHS standards as indicated in official documentation. Ensure compatibility with existing development tools supporting the C8051F06x family. Check for any obsolescence notices regarding new design recommendations.

Selection Notes

Select this model when dual 16-bit ADCs are required alongside standard 8051 compatibility. Consider the 100-pin form factor for designs needing extensive I/O or external memory interfaces. Evaluate power consumption requirements against the specified 2.7 V to 3.6 V operating range. Compare performance needs against the 25 MHz maximum clock speed.

Part Context

This component belongs to the C8051F06x series of mixed-signal microcontrollers. The family shares a common CIP-51 core architecture but varies in peripheral configurations and memory sizes. The C8051F064 variant specifically targets applications demanding high-resolution analog conversion capabilities integrated with digital control functions.

Replacement Considerations

Consult official substitution guides for compatible parts within the C8051F06x family. Verify pinout and peripheral compatibility before replacing. No public confirmed substitute part numbers are listed.
