25AA160DT-E/MNY

Memory IC Overview

The Microchip Technology 25AA160DT-E/MNY is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It utilizes an SPI-compatible serial bus for data access, supporting clock frequencies up to 10 MHz at VCC levels between 4.5V and 5.5V. The device features a 32-byte page size and operates within a supply voltage range of 1.8V to 5.5V. It is housed in an 8-lead TDFN package and supports an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed SPI communication with sequential read capabilities and hold functionality for bus pausing.
• Includes hardware write protection via the WP pin and software block protection for array segments.
• Features built-in power-on/off data protection and a write enable latch to prevent inadvertent writes.

Memory IC Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Memory IC Procurement Notes

Verify the specific suffix 'DT' indicates tape-and-reel packaging and 'E' denotes automotive temperature grade when cross-referencing datasheets. Confirm that the MNY package corresponds to the 2x3 TDFN form factor. Ensure compatibility with the required voltage levels and interface protocols before integration into the design.

Memory IC Selection Notes

Select this component for applications requiring low-power CMOS technology and robust data retention exceeding 200 years. Consider the 32-byte page buffer for efficient bulk data writing compared to 16-byte variants. Verify that the operating temperature range meets the environmental requirements of the target application.

Memory IC Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs. It shares architectural similarities with other devices in the series but differs in page size and voltage specifications. The 'D' variant specifically provides a 32-byte page structure, distinguishing it from the 16-byte 'C' version.
