25LC160CT-E/SN16KVAO

Overview

The Microchip Technology 25LC160CT-E/SN16KVAO is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz. The device utilizes a 16-byte page size and is housed in an 8-lead SOIC package. It is qualified for automotive applications, supporting an extended temperature range from -40°C to +125°C.

Feature Summary

• Supports serial communication via a standard SPI bus with separate data input and output lines.
• Includes hardware write protection capabilities controlled by the WP pin and STATUS register bits.
• Features a HOLD pin that allows suspension of serial communication without resetting the sequence.

Applications

• Automotive electronic systems requiring non-volatile data storage
• Industrial control devices needing reliable parameter retention
• Microcontroller-based embedded systems utilizing SPI interfaces

Procurement Notes

Verify the specific suffix 'E' confirms automotive qualification and the 'SN' indicates the SOIC package type. Confirm the 'T' designation matches the required reel packaging format. Ensure the datasheet revision aligns with current manufacturing specifications before finalizing procurement orders.

Selection Notes

Select this component when automotive-grade reliability and wide operating temperatures are required. The 16-byte page size suits applications with smaller data updates. Verify system voltage compatibility with the 2.5 V to 5.5 V range and ensure SPI master timing meets the 10 MHz maximum requirement.

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. All variants share identical electrical characteristics and pinouts, differing primarily in page buffer capacity.

Replacement Considerations

The 25LC160DT-E/SN serves as a direct functional substitute, offering identical performance with a 32-byte page size instead of 16 bytes. Other family members like the 25LC160C-I/SN provide industrial temperature ranges but lack automotive qualification.
