C8051T617-GM

Overview

The C8051T617-GM is a mixed-signal microcontroller from the Silicon Labs C8051T61x series, featuring an 8051 core with up to 25 MIPS throughput at a 25 MHz clock. It includes 8 kB of byte-programmable EPROM and 1280 bytes of internal data RAM. The device operates on a supply voltage of 1.8 V to 3.6 V and supports a temperature range of –40 °C to +85 °C. It is housed in a 24-pin QFN package.

Feature Summary

• Features a high-speed pipelined 8051 core executing instructions in 1 or 2 system clocks for efficient processing.
• Includes a programmable precision internal oscillator with ±2% accuracy, supporting crystal-less UART operation.
• Provides hardware-enhanced serial communication interfaces including UART, SMBus, and SPI.
• Integrates four general-purpose 16-bit counter/timers and a 16-bit Programmable Counter Array (PCA) with PWM functionality.

Applications

• Battery-powered systems requiring low power consumption
• Industrial control applications
• Consumer electronics devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type and temperature grade. Check for current availability status as this family may be subject to lifecycle changes. Ensure compliance with relevant regulatory standards such as RoHS before integration into final products.

Selection Notes

Select this model when a compact 24-pin form factor is required alongside 8 kB of non-volatile memory. Consider alternatives within the C8051T61x series if additional ADC channels or larger memory sizes are needed. Evaluate the absence of an onboard ADC against application requirements, as this specific variant lacks analog-to-digital conversion capabilities found in other members of the family.

Part Context

This component belongs to the C8051T61x family of mixed-signal microcontrollers designed for cost-sensitive applications. The T617 variant specifically utilizes the 24-pin QFN package, distinguishing it from the 28-pin and 32-pin options available in the same series. It shares the same core architecture and peripheral set as its siblings, differing primarily in pin count and memory configuration.

Replacement Considerations

Direct substitutes include other variants within the C8051T61x series, such as the C8051T616-GM, which shares the same 24-pin QFN package and core specifications. Verify pin compatibility and memory size differences when selecting an alternative part number from the same manufacturer family.
