C8051T606-GTR

Overview

The C8051T606-GTR is an 8-bit mixed-signal microcontroller from Silicon Labs, featuring a pipelined CIP-51 core operating at up to 25 MHz. It integrates 1.5 KB of byte-programmable EPROM and 128 bytes of internal SRAM. The device operates on a supply voltage range of 1.8 V to 3.6 V and supports an industrial temperature range of -40°C to +85°C. Key peripherals include a hardware-enhanced UART, SMBus interface, three general-purpose 16-bit timers, and a 16-bit Programmable Counter Array (PCA). It utilizes a priority crossbar decoder for flexible I/O mapping and includes an on-chip debug circuit.

Feature Summary

• Integrates a high-speed 8051-compatible CPU with pipelined architecture executing most instructions in one or two system clocks.
• Features a programmable priority crossbar decoder allowing flexible assignment of digital and analog peripheral functions to port pins.
• Includes on-chip debug circuitry supporting full-speed, non-intrusive in-system debugging via the C2 interface.
• Provides a calibrated precision internal oscillator with ±2% accuracy, enabling crystal-less UART operation.

Applications

• Embedded systems requiring compact form factors
• Battery-powered devices utilizing low-voltage operation
• Industrial control applications within specified temperature ranges

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package type matches design requirements, as this model is available in MSOP-10. Check datasheet revisions for updates regarding electrical characteristics. Ensure compatibility with existing development tools and programming interfaces before integration into production workflows.

Selection Notes

Select this component for designs prioritizing code density and flexibility over raw processing power. The EPROM memory allows for field reprogrammability without external storage. Consider the limited RAM size when evaluating complex algorithm requirements. The integrated oscillator simplifies board layout by reducing external component count compared to crystal-based solutions.
