25AA160DT-E/MS

Memory IC Overview

The Microchip Technology 25AA160DT-E/MS is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It utilizes low-power CMOS technology with a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 10 MHz. The device offers 2048 x 8-bit organization, 32-byte page write capability, and block write protection. It operates within industrial (-40°C to +85°C) and automotive (-40°C to +125°C) temperature ranges, housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Supports high-speed serial communication via SPI bus with hold functionality for interrupt servicing
• Includes built-in hardware and software write protection mechanisms including power-on data protection
• Features self-timed erase and write cycles with automatic address pointer incrementation

Memory IC Applications

• Microcontroller system data storage
• Industrial control applications
• Automotive electronic modules

Memory IC Procurement Notes

Verify the specific suffix 'DT' indicates the 32-byte page size variant and 'E' denotes the extended temperature grade. Confirm the 'MS' suffix corresponds to the MSOP package type. Ensure compatibility with the required voltage levels and SPI timing parameters before integration into the design.

Memory IC Selection Notes

Select this component when a 16 Kbit EEPROM with SPI interface is required for environments demanding operation up to 125°C. The automotive-grade temperature rating distinguishes it from standard industrial versions. Consider the 32-byte page size for efficient bulk data writing compared to smaller page alternatives.

Memory IC Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs. It shares architectural similarities with the 25LC160 series but differs in minimum operating voltage and temperature specifications. The 'D' designation specifically identifies the 32-byte page structure within the product line.

Memory IC Replacement Considerations

Direct substitutes include other 25AA160 variants with matching package and temperature grades, such as 25AA160DT-I/MS if automotive rating is not critical.
