25AA160DT-I/MS

Memory IC Overview

The Microchip Technology 25AA160DT-I/MS is a 16 Kbit Serial Electrically Erasable PROM featuring a 2 k x 8 organization. It utilizes an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC ≥ 4.5V. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. It employs low-power CMOS technology with standby current as low as 1 µA. The component is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Supports sequential read operations and page write capabilities with up to 32 bytes per page for the 'D' version devices.
• Includes built-in write protection mechanisms such as a write enable latch, power-on/off data protection, and a dedicated write-protect pin.
• Features block write protection allowing selection of none, 1/4, 1/2, or all array segments via the STATUS register.

Memory IC Applications

• Data storage in microcontroller systems requiring non-volatile memory
• Configuration parameter storage in embedded applications
• Calibration data retention in industrial control systems

Memory IC Procurement Notes

Verify the specific suffix 'DT' 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 system design accommodates the 1.8V to 5.5V operating voltage range. Check for RoHS compliance requirements against the latest manufacturer documentation.

Memory IC Selection Notes

Select this part for applications requiring SPI interface compatibility with standard microcontrollers. Choose the 'D' variant if 32-byte page writes are preferred over 16-byte pages. Consider the MSOP package for space-constrained surface-mount designs. Verify that the 10 MHz clock speed meets the system timing requirements at the lowest expected supply voltage.

Memory IC Part Context

This component belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. It shares functional similarities with the 25LC160 series but differs in minimum operating voltage specifications. The device is designed for direct interfacing with popular microcontroller families including PIC® controllers.

Memory IC FAQ

How does the HOLD pin function during serial communication?

The HOLD pin suspends transmission without resetting the serial sequence. When pulled low while SCK is low, it places inputs in a high-impedance state. Communication resumes when HOLD is brought high while SCK is low.

What determines the page size for this device?

The 'D' version of the device supports a 32-byte page size, whereas the 'C' version supports a 16-byte page size. Page write operations must not cross physical page boundaries.
