C8051T605-GSR

Overview

The C8051T605-GSR is a mixed-signal microcontroller from the Silicon Labs C8051T60x family, featuring an 8-bit 8051 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 and operates within a supply voltage range of 1.8 to 3.6 V. It integrates one SMBus interface, one UART, three 16-bit timers, and a programmable counter array. The component is housed in a 14-pin SOIC package and functions across a temperature range of –40 to +85 °C.

Feature Summary

• Features a high-speed 8051 core with pipelined instruction execution for efficient processing.
• Includes on-chip debug circuitry supporting non-intrusive in-system debugging and breakpoints.
• Integrates analog peripherals such as a comparator with programmable hysteresis and response time.
• Provides hardware-enhanced serial communication ports including SMBus and UART.

Applications

• In-circuit code development platform using compatible devices like C8051F300
• Systems requiring byte-programmable EPROM for firmware storage
• Applications needing low-current comparators and interrupt/reset sources

Procurement Notes

Verify that the ordering suffix GSR corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm the component status as Not Recommended for New Designs (NRND) before finalizing any long-term production plans. Ensure compatibility with existing design infrastructure given the legacy status of this silicon generation.

Selection Notes

Select this component only if the application specifically requires byte-programmable EPROM rather than standard Flash memory. Evaluate the 25 MHz performance ceiling against system timing requirements. Consider the limited pin count and peripheral set compared to newer Silicon Labs MCU families when assessing future scalability.

Part Context

This part belongs to the C8051T60x series of mixed-signal microcontrollers. The family shares a common architectural foundation but varies in memory size and package options. The C8051T605 variant specifically offers 2 kB of EPROM and utilizes the SOIC-14 package format, distinguishing it from QFN or MSOP variants in the same series.
