C8051F206R

Overview

The C8051F206R is an 8-bit mixed-signal microcontroller from Silicon Labs, part of the C8051F2xx family. It features a CIP-51 core operating at up to 25 MHz with 8 kB ISP Flash and 1.25 kB XRAM. The device includes a 12-bit SAR ADC with up to 32 channels and two comparators. Digital peripherals include hardware UART, SPI, three 16-bit timers, and a watchdog timer. It operates on 2.7V to 3.6V supply voltage within a -40°C to +85°C temperature range.

Feature Summary

• Integrated 12-bit SAR ADC with multi-channel input multiplexer
• Hardware-implemented UART and SPI serial interfaces
• On-chip JTAG debug circuitry for non-intrusive in-system debugging
• In-circuit reprogrammable Flash memory

Applications

• Data acquisition systems requiring high-resolution analog input
• Industrial control applications with sensor interface needs
• Portable instrumentation utilizing low-power modes
• Embedded systems requiring robust digital communication protocols

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the 48-TQFP specification. Check manufacturing date codes and lot traceability records. Ensure compliance with relevant environmental standards applicable to your region. Validate that the specific revision matches your design requirements.

Selection Notes

Select this model when 12-bit resolution is required for analog signals. Compare RAM sizes against other family members like the C8051F220 if memory constraints differ. Consider the 48-TQFP package dimensions for PCB layout compatibility. Evaluate power consumption profiles against system battery life requirements. Verify peripheral availability matches the specific application interface needs.

Part Context

This component belongs to the C8051F2xx series of fully integrated mixed-signal System-on-Chip MCUs. The family shares a common 8051-compatible core architecture but varies in analog peripherals and memory size. The C8051F206 specifically distinguishes itself by offering the highest resolution ADC within the base flash capacity models.

Replacement Considerations

Consult official Silicon Labs documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout and electrical characteristics. Verify software compatibility with the target instruction set architecture before implementation.
