25LC160D-I/P

Overview

The Microchip Technology 25LC160D-I/P is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with SCK, SI, SO, and CS signals for data access. The device supports a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. It operates within a supply voltage range of 2.5V to 5.5V and includes a 32-byte page size. The component is housed in an 8-lead PDIP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports sequential read operations with automatic address pointer incrementation
• Includes built-in write protection via power-on/off circuitry and a dedicated write-protect pin
• Features block write protection allowing selective array segment locking
• Provides a hold function to pause serial communication without resetting the sequence

Applications

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

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'P' denotes the PDIP package. Confirm the 'D' variant indicates the 32-byte page size rather than the 16-byte 'C' version. Ensure the datasheet revision matches the required specifications for your design implementation.

Selection Notes

Select this component when an SPI interface is required for non-volatile memory with moderate density. The industrial temperature rating suits general-purpose electronics. Consider the 32-byte page write capability for efficient data handling. Verify voltage compatibility with the host microcontroller logic levels before integration.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. It shares architectural similarities with the 25AA160 series but differs in minimum operating voltage requirements. The device is designed for direct interfacing with popular microcontroller families supporting standard SPI protocols.

Replacement Considerations

The 25LC160C-I/P serves as a functional alternative with identical electrical characteristics but utilizes a 16-byte page size instead of 32 bytes. Other variants within the 25LC160 family may offer different packaging options such as SOIC or TSSOP while maintaining the same core functionality.
