25AA160DT-I/MNY

Memory IC Overview

The Microchip Technology 25AA160DT-I/MNY is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device supports 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 rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports block write protection allowing selection of none, 1/4, 1/2, or all array segments.
• Includes built-in power-on/off data protection circuitry and a write enable latch.
• Features a hold pin to pause serial communication without resetting the sequence.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'DT' confirms the TDFN package and 'I' indicates the industrial temperature grade. Confirm the 'MNY' designation matches the required 8-lead TDFN footprint. Ensure the source document explicitly lists this full part number as available, as datasheets often group variants under generic series codes like 25XX160D.

Memory IC Selection Notes

Select this component when a low-profile surface-mount package is required alongside a wide 1.8V to 5.5V operating voltage range. The 32-byte page size offers higher throughput compared to 16-byte variants. Verify that the host microcontroller supports the standard SPI Mode 0,0 or Mode 1,1 timing requirements specified in the AC characteristics.

Memory IC Part Context

This device belongs to the 25AA160C/D family of 16 Kbit Serial EEPROMs. The 'D' variant specifically provides a 32-byte page buffer, distinguishing it from the 'C' version which uses a 16-byte page. The 'AA' prefix denotes the 1.8V compatible voltage range, while 'LC' variants typically start at 2.5V.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: 25AA160CT-I/ST (TSSOP), 25AA160AT-I/MS (MSOP). These share identical electrical specifications but differ in physical package dimensions.
