25AA160DT-I/SN

Memory IC Overview

The Microchip Technology 25AA160DT-I/SN is a 16 Kbit Serial Electrically Erasable PROM featuring a 2K x 8 organization and 32-byte page size. It operates via an SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device supports a supply voltage range of 1.8V to 5.5V and functions within an industrial temperature range of -40°C to +85°C. Packaged in an 8-lead SOIC, it offers high reliability with over 1 million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports sequential read operations and self-timed erase/write cycles with a maximum duration of 5 ms.
• Includes built-in write protection mechanisms such as power-on/off data protection, a write enable latch, and a dedicated write-protect pin.
• Features block write protection allowing configuration to protect none, one-quarter, one-half, or the entire memory array.

Memory IC Applications

• Data storage for microcontroller systems requiring non-volatile memory
• Configuration parameter storage in embedded devices
• Calibration data retention in industrial instrumentation

Memory IC Procurement Notes

Verify the specific suffix 'I/SN' corresponds to the Industrial temperature grade (-40°C to +85°C) and SOIC-8 package. Confirm the 'D' variant designation indicates the 32-byte page size rather than the 16-byte 'C' version. Ensure compatibility with the target system's SPI voltage levels and check for RoHS compliance requirements.

Memory IC Selection Notes

Select this component when a low-pin-count EEPROM with hardware write protection is required. The 1.8V minimum operating voltage makes it suitable for low-power applications compared to 2.5V-only alternatives. The 32-byte page size allows for more efficient bulk data writes compared to smaller page variants.

Memory IC Part Context

This part belongs to the 25XX160C/D family of 16 Kbit SPI Serial EEPROMs from Microchip Technology. It shares functional similarities with the 25LC160 series but differs in its lower 1.8V operating voltage capability. The 'D' suffix denotes the 32-byte page architecture, distinguishing it from the 16-byte page 'C' version.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: 25AA160C-I/SN (16-byte page), 25LC160DT-I/SN (2.5V min voltage).
