25LC160D-E/SN

Overview

The Microchip Technology 25LC160D-E/SN is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM accessed via an SPI-compatible bus. It features a 32-byte page size and operates within a voltage range of 2.5V to 5.5V. The device supports a maximum clock frequency of 10 MHz at VCC ≥ 4.5V, with read access times as fast as 50 ns. It is housed in an 8-lead SOIC package and rated for automotive temperatures from -40°C to +125°C.

Feature Summary

• Supports serial peripheral interface communication with hold functionality for interrupt servicing
• Includes hardware write protection via dedicated pin and software block protection registers
• Features built-in power-on/off data protection and self-timed erase/write cycles

Applications

• Automotive embedded systems requiring extended temperature operation
• Microcontroller data storage for configuration parameters
• Industrial control devices needing non-volatile memory retention

Procurement Notes

Verify the specific suffix 'E' confirms the automotive temperature grade (-40°C to +125°C) and 'SN' indicates the SOIC-8 package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability for automotive-grade components.

Selection Notes

Select this component when automotive reliability and wide operating voltage ranges are required. Compare against the 'I' variant if industrial temperature grades suffice. Verify that the 32-byte page size aligns with application write patterns to optimize performance. Ensure SPI master compatibility with Mode 0,0 or Mode 1,1 settings.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs. The 'D' designation specifies a 32-byte page buffer, distinguishing it from the 16-byte 'C' version. The 'LC' prefix indicates low-voltage CMOS technology compatible with standard logic levels.
