C8051F066-GQ

Overview

The C8051F066-GQ is a mixed-signal microcontroller from Silicon Labs featuring the CIP-51 core. It integrates 32 kB of in-system programmable Flash memory, 4352 bytes of internal data RAM, and two 16-bit SAR ADCs. The device provides 59 general-purpose I/O pins and supports multiple digital peripherals including SMBus, SPI, and dual UARTs. Operating within a supply voltage range of 2.7 V to 3.6 V, it functions across a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates two 16-bit SAR ADCs with direct memory access capability for high-speed data acquisition without software overhead.
• Features a fully 8051 compatible CIP-51 core with pipelined architecture executing up to 70% of instructions in one or two system clocks.
• Includes on-chip JTAG debug circuitry supporting breakpoints, single-stepping, and boundary scan compliance.

Applications

• Industrial control systems requiring precise analog signal processing
• Data acquisition modules utilizing high-resolution ADCs
• Embedded applications needing simultaneous serial communication via multiple UARTs

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements. Review datasheet specifications for absolute maximum ratings prior to integration. Validate pinout compatibility with target PCB layout constraints.

Selection Notes

Select this component for designs requiring high-resolution analog conversion alongside robust digital connectivity. The integrated 16-bit ADCs suit precision measurement tasks. Evaluate memory capacity against application code size. Consider the 59 available I/O lines for complex peripheral interfacing needs.
