25LC160DT-E/MNY16KVAO

Overview

The Microchip Technology 25LC160DT-E/MNY is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It utilizes a 2K x 8 organization with a 32-byte page size, characteristic of the 'D' version devices. The component operates within a supply voltage range of 2.5V to 5.5V and supports maximum clock frequencies up to 10 MHz at higher voltages. Designed for automotive applications, it functions reliably across an extended temperature range from -40°C to +125°C. The device is housed in an 8-lead TDFN package.

Feature Summary

• Supports high-speed serial communication via a standard SPI bus interface.
• Includes built-in hardware write protection mechanisms and power-on data protection circuitry.
• Features a hold pin capability to pause serial transmission without resetting the sequence.

Applications

• Automotive electronic systems requiring extended temperature reliability
• Industrial control units needing non-volatile data storage
• Microcontroller-based embedded memory expansion

Procurement Notes

Verify the specific suffix 'MNY' corresponds to the TDFN-8 package and reel packaging configuration. Confirm the 'E' designation indicates the automotive grade operating temperature range of -40°C to +125°C. Ensure compatibility with the required 32-byte page write architecture when integrating into the system design.

Selection Notes

Select this component for designs requiring automotive-grade reliability and extended temperature operation. The 32-byte page size offers efficient bulk writing compared to smaller page variants. Verify that the system voltage remains within the 2.5V to 5.5V operational window to ensure proper SPI timing and signal integrity.

Part Context

This part belongs to the 25LC160C/D family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'D' variant specifically denotes a 32-byte page size, distinguishing it from the 16-byte 'C' version. The 'E' suffix identifies the automotive qualification level, ensuring performance under harsh environmental conditions typical of vehicle electronics.

Replacement Considerations

Direct substitutes include other 25LC160D variants with different packages such as SOIC or TSSOP, provided the pinout remains compatible. Cross-family replacements like the 25AA160D are functionally similar but operate at lower minimum voltages.
