C8051T616-GMR

Overview

The C8051T616-GMR is a mixed-signal microcontroller from the Silicon Labs C8051T61x family, featuring an 8-bit CIP-51 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 integrates a 10-bit ADC supporting up to 500 ksps with up to 13 external inputs, two comparators, and a built-in temperature sensor. Digital peripherals include a hardware-enhanced UART, SMBus, SPI, four 16-bit timers, and a 16-bit PCA with five capture/compare modules. It operates on a supply voltage of 1.8 V to 3.6 V within a temperature range of –40 °C to +85 °C.

Feature Summary

• Integrates a high-speed 8051-compatible CPU with pipelined architecture for efficient instruction execution.
• Includes analog peripherals such as a 10-bit ADC, programmable comparators, and a temperature sensor.
• Features comprehensive digital communication interfaces including UART, SMBus, and SPI.
• Provides non-volatile byte-programmable EPROM memory for code storage.

Applications

• Embedded systems requiring mixed-signal processing
• Industrial control applications
• Sensor interface circuits
• Battery-powered devices

Procurement Notes

Verify that the component matches the specific ordering suffix GMR for tape-and-reel packaging. Confirm the revision level against the latest datasheet Rev 1.1. Note that this series is marked Not Recommended for New Designs; evaluate long-term availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this model when a compact 24-pin QFN package is required alongside 8 kB of EPROM. Ensure the application utilizes the 10-bit ADC and comparator features available in the T616 variant. Verify that the 1.8 V to 3.6 V operating voltage range aligns with the system power supply constraints.

Part Context

This part belongs to the C8051T61x family of mixed-signal MCUs. It shares the same core architecture and peripheral set as other members like the C8051T610 and C8051T611, differing primarily in memory size and package type. The T616 specifically offers 8 kB EPROM in a 24-pin QFN form factor.

Replacement Considerations

Direct substitutes within the same family include C8051T617-GMR, which shares identical specifications but may differ in packaging or revision. Cross-family migration to C8051F series parts requires software adaptation due to architectural differences.
