25LC160B-I/SN

Overview

The Microchip Technology 25LC160B-I/SN 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 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 SOIC package.

Feature Summary

• Supports 32-byte page write operations for efficient data storage
• Includes hardware write protection via the WP pin and software block protection
• Features self-timed erase and write cycles with internal timing control

Applications

• Microcontroller system data logging
• Configuration parameter storage
• Calibration value retention

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade and 'SN' denotes the SOIC package. Confirm RoHS compliance status through official manufacturer documentation prior to integration into final assemblies.

Selection Notes

Select this component when a 32-byte page size is required over the 16-byte variant. Ensure the application environment remains within the specified industrial temperature limits and voltage constraints for reliable operation.

Part Context

This part belongs to the 25XX160A/B family of 16 Kbit EEPROMs. The 'B' designation specifically indicates support for 32-byte pages, distinguishing it from the 'A' version which uses 16-byte pages. It shares the same interface and core architecture as other members of the series.

Replacement Considerations

Direct substitutes include the 25LC160B-I/ST (TSSOP package) or 25LC160B-I/MS (MSOP package). Verify that any replacement maintains the identical 32-byte page size and voltage specifications.
