25AA160DT-E/SN

Memory IC Overview

The Microchip Technology 25AA160DT-E/SN is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It utilizes a 2048 x 8-bit organization with a 32-byte page size, characteristic of the 'D' version devices. The component operates within a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz at higher voltages. It is housed in an 8-lead TSSOP package and is rated for an extended industrial temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed serial communication via a standard SPI bus with hold functionality for interrupt servicing
• Includes hardware write protection mechanisms such as block protection and power-on data protection circuitry
• Features self-timed erase and write cycles with internal write cycle completion monitoring

Memory IC Applications

• Microcontroller system data storage requiring non-volatile memory retention
• Industrial control applications operating within extended temperature environments
• Embedded systems utilizing SPI interfaces for configuration parameter storage

Memory IC Procurement Notes

Verify the specific suffix 'DT' against official documentation to confirm tape-and-reel packaging and automotive-grade temperature rating. Confirm that the 'E' designation aligns with the required -40°C to +125°C operational range. Ensure compatibility with existing PCB footprints for the 8-lead TSSOP package before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an SPI EEPROM is required for applications demanding operation down to 1.8V and extended temperature ranges up to 125°C. The 'D' variant provides a 32-byte page buffer, which may improve write efficiency compared to 16-byte variants. Verify that the host microcontroller supports the necessary SPI modes and voltage levels for reliable data transfer.

Memory IC Part Context

This device belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants with different page sizes and voltage ranges, distinguished by suffixes such as 'C' or 'D'. The 25AA series specifically denotes low-voltage operation starting at 1.8V, distinguishing it from the 25LC series which typically requires a minimum of 2.5V.

Memory IC Replacement Considerations

Direct substitutes include other 25AA160D variants with compatible pinouts and specifications, such as 25AA160D-I/ST or 25AA160D-E/MS, provided they match the required temperature grade and package type.
