25AA160CT-I/SN

Memory IC Overview

The Microchip Technology 25AA160CT-I/SN 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 at VCC voltages between 4.5V and 5.5V. The device supports a supply voltage range of 1.8V to 5.5V and utilizes a 16-byte page size for write operations. It is housed in an 8-lead SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports sequential read operations with automatic address pointer incrementation across the memory array.
• Includes built-in hardware write protection via the WP pin and software-configurable block protection levels.
• Features a hold function that suspends serial communication without resetting the current sequence state.

Memory IC Applications

• Data storage for configuration parameters in microcontroller systems
• Logging operational data in industrial monitoring equipment
• Storing calibration constants in embedded sensor modules

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' against official documentation, as it typically indicates tape-and-reel packaging which may differ from standard tube quantities. Confirm the 'I' designation corresponds to the industrial temperature grade (-40°C to +85°C) required for your application environment. Ensure the 'SN' suffix matches the 8-lead SOIC package dimensions for PCB footprint compatibility.

Memory IC Selection Notes

Select this component when a low-pin-count non-volatile memory solution is needed for small data sets. The 16-byte page size limits efficient bulk writes compared to 32-byte variants. Verify that the host controller can support the required SPI timing constraints, particularly setup and hold times, across the full operating voltage range.

Memory IC Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs. The 'C' variant specifically denotes a 16-byte page size, distinguishing it from the 'D' variant which offers 32-byte pages. The 'AA' prefix indicates a wide voltage range starting at 1.8V, unlike the 'LC' series which starts at 2.5V.

Memory IC Replacement Considerations

The 25AA160DT-I/SN serves as a direct functional substitute within the same package, offering identical electrical characteristics but utilizing a 32-byte page size instead of 16 bytes. Application software must be adjusted to accommodate the different page boundary logic during write operations.
