25LC160DT-E/SN

Overview

The Microchip Technology 25LC160DT-E/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 at VCC levels between 4.5V and 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports a 32-byte page size. It is housed in an 8-lead SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz
• Includes built-in write protection mechanisms such as power-on/off data protection and a write enable latch
• Features a hold pin that allows pausing serial communication without resetting the sequence
• Provides block write protection allowing selection of none, 1/4, 1/2, or all array segments

Applications

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

Procurement Notes

Verify the specific suffix 'DT' indicates tape and reel packaging and 'E' denotes automotive temperature grade when cross-referencing official documentation. Confirm the exact operating temperature range and voltage specifications against the manufacturer's datasheet prior to integration to ensure compatibility with the target application environment.

Selection Notes

Select this component for applications requiring non-volatile memory with SPI interface compatibility. Ensure the design accommodates the 32-byte page write limitation and the internal write cycle time. Verify that the system voltage remains within the specified 2.5V to 5.5V range to maintain reliable operation and data integrity during read and write sequences.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. The family shares common architectural features including SPI interface and self-timed erase/write cycles. Variations within the family differ primarily by page size ('C' vs 'D'), voltage range (AA vs LC), and temperature grades (I vs E).

Replacement Considerations

Compatible substitutes include other 25LC160 variants with matching SOIC-8 packages and SPI interfaces. Ensure replacement parts support the required 32-byte page size and operate within the necessary voltage and temperature ranges.
