25AA160D-I/SN

Memory IC Overview

The Microchip Technology 25AA160D-I/SN is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit 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 block write protection allowing selection of none, one-quarter, one-half, or all array segments.
• Includes built-in power-on/off data protection circuitry and a write enable latch for secure operations.
• Features a hold pin that pauses serial communication without resetting the sequence, enabling host interrupt servicing.

Memory IC Applications

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

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 RoHS compliance and Pb-free status as stated in the datasheet. Ensure the ordering part number matches the exact device variant required for your application's voltage and speed specifications.

Memory IC Selection Notes

Select this component when a 16 Kbit capacity with a 32-byte page size is required for SPI-based systems. It is suitable for applications needing low-power CMOS technology and robust write protection features. Consider the 1.8V minimum operating voltage for compatibility with lower voltage logic families compared to the 2.5V minimum of the LC series.

Memory IC Part Context

This device belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. The 'AA' designation indicates a 1.8V minimum operating voltage, distinguishing it from the 'LC' series which requires a minimum of 2.5V. The 'D' suffix specifies the 32-byte page size architecture.

Memory IC Replacement Considerations

The 25AA160C-I/SN serves as a direct functional substitute but utilizes a 16-byte page size instead of 32 bytes. Designers must adjust software page write algorithms accordingly to prevent data corruption across page boundaries.
