25LC160DT-I/ST

Overview

The Microchip Technology 25LC160DT-I/ST is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It utilizes Low-Power CMOS technology with a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V, reducing to 5 MHz at 2.5V to 4.5V. The device offers a 32-byte page size for the 'D' version and supports industrial temperature ranges from -40°C to +85°C. It operates within a voltage range of 2.5V to 5.5V, housed in an 8-lead TSSOP package.

Feature Summary

• Supports serial communication via a standard four-wire SPI bus including Chip Select, Serial Clock, Serial Input, and Serial Output lines.
• Includes hardware write protection capabilities controlled by the Write-Protect pin and internal status register bits.
• Features a Hold input that allows suspension of serial data transmission without resetting the current sequence.

Applications

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

Procurement Notes

Verify the specific suffix 'DT' against official documentation to confirm tape and reel packaging details. Ensure the ordering code matches the required temperature grade and package type. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a 16 Kbit non-volatile memory solution with SPI compatibility is required. The 'D' variant provides a larger 32-byte page buffer compared to the 16-byte 'C' version. Verify that the system voltage remains within the 2.5V to 5.5V operating range to ensure proper functionality and endurance specifications are met.

Part Context

This part belongs to the 25LC160C/D family of serial EEPROMs manufactured by Microchip Technology. These devices are designed for applications requiring reliable data retention and high endurance. The family shares common instruction sets and electrical characteristics, differing primarily in page size and specific package options available for integration into various circuit designs.

Replacement Considerations

Compatible substitutes include other 16Kbit SPI EEPROMs from Microchip such as the 25AA160 series or variants with different suffixes like /ST or /MS, provided they match the required voltage and temperature specifications.
