25LC160A-E/MS

Overview

The Microchip Technology 25LC160A-E/MS is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It utilizes an SPI-compatible serial bus for communication, featuring a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports an extended industrial temperature range from -40°C to +125°C. It incorporates a 16-byte page write buffer and offers high reliability with over 1,000,000 erase/write cycles and data retention exceeding 200 years.

Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz
• Includes built-in hardware write protection via the WP pin and software block protection
• Features self-timed erase and write cycles with automatic power-on/off data protection
• Provides hold functionality to pause serial transmission without resetting the sequence

Applications

• Microcontroller system data storage
• Industrial control applications requiring extended temperature ranges
• Automotive electronic modules
• Embedded systems requiring non-volatile parameter storage

Procurement Notes

Verify the Automotive grade designation 'E' corresponds to the required -40°C to +125°C operating range. Confirm the MSOP-8 package matches the PCB footprint. Ensure the specific revision suffix aligns with current manufacturing standards as this component may be subject to lifecycle changes.

Selection Notes

Select this part when an SPI interface is preferred over I2C or Microwire protocols. Choose the 'A' version specifically if the application requires a 16-byte page size rather than the 32-byte page size found in the 'B' variant. Ensure the system voltage remains within the 2.5V to 5.5V operational limits.

Part Context

This component belongs to the 25LC160A/B family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 25AA160A but differs in minimum operating voltage requirements. The 'E' suffix denotes the automotive-grade temperature rating, distinguishing it from standard industrial versions.

Replacement Considerations

Public confirmed substitute part numbers include 25LC160BT-E/MS.
