C8051T617-GMR

Overview

The C8051T617-GMR is a mixed-signal microcontroller from the Silicon Labs C8051T61x family, 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 range of 1.8 V to 3.6 V and supports an industrial 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 capable of executing 70% of instructions in one or two system clocks.
• Includes hardware-enhanced serial communication interfaces such as UART, SMBus, and SPI.
• Integrates a 16-bit Programmable Counter Array (PCA) with capture/compare modules and PWM functionality.
• Provides on-chip debug circuitry for full-speed, non-intrusive in-system debugging.

Applications

• Embedded systems requiring byte-programmable memory
• Industrial control applications
• Sensor interface circuits
• Motor control systems

Procurement Notes

Verify component status before procurement as this part may be marked Not Recommended for New Designs. Confirm package type and suffix specifications against official documentation to ensure compatibility with existing designs. Check for end-of-life announcements or last-time buy notices prior to ordering.

Selection Notes

Select this model when an 8051 architecture with EPROM storage is required. Ensure the design utilizes the 24-pin QFN footprint. Verify that the 1.8 V to 3.6 V operating voltage aligns with system power rails. Consider the absence of an ADC in this specific variant compared to other members of the T61x family.

Part Context

This component belongs to the C8051T61x series of mixed-signal microcontrollers. It shares architectural similarities with variants like the C8051T610 through C8051T616 but differs in memory size and peripheral availability. The GMR suffix indicates a tape-and-reel packaging option suitable for automated assembly processes.

Replacement Considerations

Consult the manufacturer's product selection guide for direct functional equivalents within the C8051T61x family. Evaluate alternative packages such as LQFP-32 or QFN-28 if pin count flexibility is required. Verify cross-compatibility of software drivers and peripheral configurations.

FAQ

Does the C8051T617 include an analog-to-digital converter?

No, the C8051T617 does not include a 10-bit ADC. This peripheral is available only in the C8051T610, C8051T611, C8051T612, C8051T613, and C8051T616 variants.

What is the maximum instruction execution speed?

The core executes up to 25 MIPS throughput when driven by a 25 MHz clock source.
