25AA160CT-I/MNY

Memory IC Overview

The Microchip Technology 25AA160CT-I/MNY is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It operates on an SPI-compatible serial bus with a maximum clock frequency of 10 MHz and supports a supply voltage range of 1.8V to 5.5V. The device utilizes a 16-byte page size for write operations and is housed in an 8-lead TDFN package. It supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes hardware write protection via WP pin and software block protection
• Features built-in power-on/off data protection circuitry
• Provides hold functionality to pause serial sequences without resetting

Memory IC Applications

• Microcontroller system data storage
• Industrial control parameter logging
• Embedded configuration memory
• Low-power portable device storage

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the 'C' version with 16-byte pages aligns with application buffer requirements. Cross-reference the MNY package code with the target PCB footprint specifications.

Memory IC Selection Notes

Select this component for applications requiring low-voltage operation down to 1.8V. The 16-byte page size suits smaller data updates compared to 32-byte variants. Verify that the host controller supports the standard SPI Mode 0,0 or Mode 1,1 timing requirements. Consider the TDFN package dimensions for space-constrained designs.

Memory IC Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs. The 'AA' prefix denotes 1.8V compatible logic levels, while 'C' specifies the 16-byte page architecture. The 'MNY' suffix identifies the 8-lead 2x3 TDFN package type used for surface-mount assembly.

Memory IC FAQ

How does the HOLD pin function during serial communication?

The HOLD pin suspends transmission when pulled low while SCK is low, tri-stating the SO line. Communication resumes when HOLD is brought high while SCK is low.

What is the purpose of the Write Enable Latch?

The Write Enable Latch must be set via the WREN instruction before any write operation can be completed. It resets automatically after power-up or a successful write cycle.
