25LC160D-E/MS

Overview

The Microchip Technology 25LC160D-E/MS is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It utilizes a 2048 x 8-bit organization with a 32-byte page size for efficient data handling. The device operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 10 MHz at higher voltages. It is housed in an 8-lead MSOP package and certified as Pb-free and RoHS compliant.

Feature Summary

• Supports serial communication via a standard SPI bus with separate data input and output lines.
• Includes hardware write protection mechanisms such as a write enable latch and dedicated write-protect pin.
• Features self-timed erase and write cycles that automatically complete without host intervention.

Applications

• Data storage in microcontroller-based systems requiring non-volatile memory
• Configuration parameter retention in industrial control devices
• Calibration data logging in automotive electronic modules

Procurement Notes

Verify the specific suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'MS' indicates the MSOP package. Confirm the 'D' designation aligns with the required 32-byte page size for your application architecture. Ensure compatibility with system voltage levels between 2.5V and 5.5V before integration.

Selection Notes

Select this component when a 16 Kbit capacity with high-speed SPI access is required. The 'D' variant provides a larger 32-byte page buffer compared to the 16-byte 'C' version, improving write throughput. The 'E' grade ensures reliability in environments exceeding standard industrial temperature limits.

Part Context

This part belongs to the 25XX160C/D family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 25AA160 series but differs in operating voltage requirements and temperature specifications. The family is designed for direct interfacing with popular microcontroller families including PIC devices.

Replacement Considerations

Public confirmed substitute part numbers: 25LC160C-E/MS (16-byte page), 25LC160D-I/MS (industrial temp). Verify package and temperature grade alignment before substitution.
