C8051T603-GSR

Overview

The C8051T603-GSR is a mixed-signal microcontroller from the Silicon Labs C8051T60x family, featuring an 8-bit CIP-51 core with pipelined architecture. It includes 2 kB of byte-programmable EPROM and 256 bytes of internal data RAM. The device supports a maximum clock frequency of 25 MHz, delivering up to 25 MIPS throughput. It operates within a supply voltage range of 1.8 V to 3.6 V and functions across a temperature range of –40 °C to +85 °C. The component is housed in a 14-pin SOIC package.

Feature Summary

• Features a high-speed 8051-compatible core with pipelined instruction execution for efficient processing.
• Integrates on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Includes hardware-enhanced UART and SMBus serial communication interfaces for reliable data transfer.
• Provides a programmable counter array (PCA) supporting PWM generation, capture/compare, and watchdog timer functions.

Applications

• Embedded systems requiring non-volatile code storage via EPROM
• Industrial control applications utilizing onboard analog peripherals
• Battery-powered devices benefiting from low-voltage operation and power management modes

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature rating. Confirm that the design accounts for the component's status as not recommended for new designs. Ensure compatibility with existing development tools and verify all electrical specifications against the official datasheet before finalizing procurement decisions.

Selection Notes

Select this component when EPROM-based code retention is necessary rather than Flash memory. Consider the C8051T60x series for designs requiring integrated analog features like comparators and temperature sensors alongside standard digital I/O. Evaluate the 25 MHz performance limit and 1.8 V minimum supply voltage against system requirements.

Part Context

The C8051T603-GSR belongs to the C8051T60x mixed-signal MCU family by Silicon Labs. This series combines an 8051-compatible processor with various analog and digital peripherals on a single chip. The T60x variant specifically utilizes byte-programmable EPROM technology for program memory, distinguishing it from Flash-based counterparts in the broader portfolio.
