25AA160B-I/SN

Memory IC Overview

The Microchip Technology 25AA160B-I/SN is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It features an SPI-compatible interface with a maximum clock frequency of 10 MHz and a 32-byte page size. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperatures from -40 °C to +85 °C. It is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports block write protection for none, 1/4, 1/2, or all array segments
• Includes built-in power-on/off data protection circuitry
• Features a dedicated hold pin to pause serial communication without resetting the sequence

Memory IC Applications

• Microcontroller system configuration storage
• Data logging applications requiring non-volatile retention
• Parameter storage in industrial control systems

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the component meets the intended operating voltage and environmental specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this part when a 32-byte page size is required for efficient sequential writes. Choose the 'I' suffix for industrial temperature ranges and the 'SN' suffix for SOIC packaging. Verify compatibility with the host microcontroller's SPI voltage levels and timing requirements.

Memory IC Part Context

This component belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs. The 'B' version specifically utilizes a 32-byte page buffer, distinguishing it from the 16-byte page 'A' version. It shares the same pinout and instruction set as other members of the series.

Memory IC Replacement Considerations

The 25LC160B-I/SN serves as a functional substitute, offering identical specifications but with a minimum operating voltage of 2.5 V instead of 1.8 V.
