C8051F065-GQR

Overview

The C8051F065-GQR is a fully integrated mixed-signal System-on-a-Chip MCU from the Silicon Labs C8051F06x family. It features a high-speed pipelined 8051-compatible CIP-51 core operating at up to 25 MHz with 25 MIPS throughput. The device 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 1 Msps throughput and Direct Memory Access, alongside three analog comparators and a precision VDD monitor. Digital interfaces include hardware SMBus, SPI, and dual UARTs. It operates on a 2.7V to 3.6V supply within a -40°C to +85°C temperature range.

Feature Summary

• Integrated dual 16-bit SAR ADCs with DMA support for high-speed data acquisition without software overhead
• High-performance CIP-51 microcontroller core executing 70% of instructions in one or two system clocks
• On-chip JTAG debug interface enabling full-speed, non-intrusive in-circuit debugging and boundary scan
• Comprehensive digital peripheral set including CAN controller, multiple timers, and serial communication ports

Applications

• Industrial control systems requiring precise analog signal processing
• Data acquisition systems utilizing high-resolution ADCs
• Embedded applications needing robust in-system debugging capabilities
• Mixed-signal monitoring devices with voltage and temperature sensing requirements

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity upon receipt as moisture sensitivity is indicated. Check revision markings against datasheet Rev 1.3 specifications. Ensure ESD precautions are followed during handling. Validate pin compatibility before integration into existing PCB layouts.

Selection Notes

Select this model when 64 kB Flash and dual 16-bit ADCs are required. Suitable for designs needing 24 digital I/O pins in a compact form factor. Consider power consumption profiles relative to the 2.7V to 3.6V operating range. Evaluate thermal performance within the specified industrial temperature limits. Compare against other C8051F06x variants if different I/O counts or memory sizes are needed.

Part Context

Part of the C8051F06x family of fully integrated mixed-signal MCUs. Shares the CIP-51 core architecture with other members like C8051F060 and C8051F066. Differentiated by specific memory configurations and I/O pin counts within the series. Designed for applications demanding high-speed processing and precise analog conversion in a single chip solution.

Replacement Considerations

Check for official successor parts from Silicon Labs. Verify pin-to-pin compatibility if substituting within the same package type. Review updated datasheets for any changes in electrical characteristics or peripheral functionality.
