25AA160DT-E/ST

Memory IC Overview

The Microchip Technology 25AA160DT-E/ST 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 supports a maximum clock frequency of 10 MHz and operates within a supply voltage range of 1.8V to 5.5V. It is housed in an 8-lead TSSOP package and is qualified for automotive applications, supporting an extended 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 built-in write protection mechanisms such as block protection, power-on data protection, and a hardware write-protect pin.
• Features self-timed erase and write cycles with internal write cycle time of up to 5 ms.

Memory IC Applications

• Automotive electronic systems requiring non-volatile memory
• Industrial control applications with wide temperature demands
• Embedded microcontroller systems needing persistent data storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm the device revision aligns with current manufacturing standards. Ensure compatibility with system voltage levels and SPI timing requirements before integration. Check for any recent product change notices affecting packaging or electrical characteristics.

Memory IC Selection Notes

Select this part when automotive qualification and extended temperature operation are mandatory. The 32-byte page size offers higher throughput compared to 16-byte variants. Ensure the design accommodates the 1.8V minimum supply voltage if operating at lower logic levels. Verify that the TSSOP package footprint fits the PCB layout constraints.

Memory IC Part Context

This component belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs. The 'A' designation indicates low-voltage operation starting at 1.8V, while the 'D' suffix specifies the 32-byte page architecture. The 'E' suffix denotes automotive-grade reliability and extended temperature performance.
