25AA160D-I/MS

Memory IC Overview

The Microchip Technology 25AA160D-I/MS 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. It utilizes low-power CMOS technology, offering high reliability with over 1 million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

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

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'MS' denotes the 8-lead MSOP package. Confirm RoHS compliance status for the specific manufacturing lot. Ensure the ordering quantity matches the required reel or cut tape specifications as defined by the manufacturer's standard packaging options.

Memory IC Selection Notes

Select this component when a 16 Kbit capacity with a 32-byte page size is required for SPI-based systems. The 1.8V minimum operating voltage makes it suitable for low-voltage applications compared to 2.5V variants. Consider the MSOP package dimensions for space-constrained surface-mount designs requiring industrial temperature stability.

Memory IC Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. The 'D' designation specifically indicates a 32-byte page size, distinguishing it from the 'C' version which uses a 16-byte page. The 'AA' prefix identifies the 1.8V compatible variant within the broader memory portfolio.

Memory IC Replacement Considerations

The 25AA160C-I/MS serves as a functional alternative but features a smaller 16-byte page size instead of 32 bytes. Other family members like the 25LC160D series operate at a higher minimum voltage of 2.5V.
