25LC160AT-I/MS

Overview

The Microchip Technology 25LC160AT-I/MS is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with a maximum clock frequency of 10 MHz and operates within a supply voltage range of 2.5 V to 5.5 V. The device supports industrial temperature ranges from -40°C to +85°C and is housed in an 8-lead MSOP package.

Feature Summary

• Supports sequential read operations and self-timed erase/write cycles
• Includes built-in write protection via power-on/off circuitry and a dedicated write-protect pin
• Features block write protection allowing selective array segment locking
• Provides hold functionality to pause communication without resetting the sequence

Applications

• Microcontroller data storage for system parameters
• Configuration memory in embedded systems
• Non-volatile data logging applications

Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature rating (-40°C to +85°C) and 'MS' denotes the 8-lead MSOP package. Confirm the 'A' variant designation aligns with the 16-byte page size requirement, as distinct from the 'B' version which utilizes a 32-byte page structure.

Selection Notes

Select this component when a low-pin-count EEPROM interface is required alongside standard SPI compatibility. Ensure the operating voltage falls within the 2.5 V to 5.5 V range and that the application environment remains within the specified industrial temperature limits for reliable operation.

Part Context

This part belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. These devices are designed for direct interfacing with microcontrollers possessing SPI ports or discrete I/O lines programmed for serial communication protocols.

Replacement Considerations

The 25AA160AT-I/MS serves as a functional substitute, offering identical specifications but supporting a lower minimum supply voltage of 1.8 V compared to the 2.5 V requirement of the 25LC160 series.
