C8051T611-GM

Overview

The C8051T611-GM is a mixed-signal microcontroller from the C8051T61x family, featuring an 8051 core with up to 25 MIPS throughput at a 25 MHz clock. It includes 16 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 17 external inputs, two comparators, and four 16-bit timers. It operates on a supply voltage of 1.8 V to 3.6 V and is housed in a 28-pin QFN package.

Feature Summary

• Features a high-speed pipelined 8051 core executing instructions in one or two system clocks for efficient processing.
• Includes integrated analog peripherals such as a 10-bit ADC with programmable window detector and low-current comparators.
• Provides comprehensive digital communication interfaces including hardware-enhanced UART, SMBus, and SPI.
• Supports non-intrusive in-system debugging via on-chip debug circuitry with breakpoint and memory inspection capabilities.

Applications

• Industrial control systems requiring mixed-signal processing
• Sensor interface applications utilizing built-in temperature sensing
• Battery-powered devices benefiting from low-voltage operation and power management modes

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors or certified partners. Confirm that the specific ordering suffix matches the required package type and temperature range. Ensure compliance with RoHS standards if applicable to your manufacturing process. Review the datasheet for any recent product change notices regarding assembly or sourcing updates before finalizing procurement orders.

Selection Notes

Select this model when byte-programmable EPROM is preferred over Flash for code storage requirements. Consider the 28-pin QFN package for compact board layouts. Evaluate the 10-bit ADC resolution and speed against application signal processing needs. Verify that the 1.8 V to 3.6 V supply range aligns with the system power architecture.

Part Context

This component belongs to the C8051T61x series of mixed-signal microcontrollers. It shares architectural similarities with other members of the T61x family but differs in pin count and peripheral availability. The series is designed for cost-sensitive applications requiring high integration and robust analog capabilities within a small form factor.

Replacement Considerations

Public documentation indicates this part is Not Recommended for New Designs. Consult official Silicon Labs resources for current alternative recommendations within the C8051F or EFM8 families that offer updated features and support status.
