25LC160D-I/SN

Overview

The Microchip Technology 25LC160D-I/SN is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization and 32-byte page size. It operates via an SPI-compatible serial bus with SCK, SI, SO, CS, and HOLD pins. The device supports a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. Operating voltage ranges from 2.5V to 5.5V. It functions within an industrial temperature range of -40°C to +85°C and utilizes an 8-lead SOIC package.

Feature Summary

• Supports self-timed erase and write cycles with a maximum duration of 5 ms.
• Includes built-in power-on/off data protection circuitry and a write enable latch.
• Provides block write protection allowing selection of none, 1/4, 1/2, or all array segments.
• Features a hold pin to pause communication without resetting the serial sequence.

Applications

• Microcontroller systems requiring non-volatile data storage
• Industrial control applications operating in wide temperature environments
• Embedded systems utilizing SPI bus interfaces

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'SN' denotes the 8-lead SOIC package. Confirm the 'D' variant indicates the 32-byte page size rather than the 16-byte page found in 'C' versions. Ensure the source document matches the DS22150B datasheet for accurate electrical specifications.

Selection Notes

Select this component when a 16 Kbit capacity with 32-byte page write capability is required. The industrial temperature rating suits environments exceeding standard commercial limits. Verify that the system voltage remains within the 2.5V to 5.5V range to ensure proper operation of the SPI interface and internal high-voltage generator.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants with different page sizes ('C' for 16 bytes, 'D' for 32 bytes) and voltage ranges (AA for 1.8V start, LC for 2.5V start). The 25LC160D specifically targets 2.5V to 5.5V applications.

Replacement Considerations

Public confirmed substitute part numbers: 25LC160D-I/MS, 25LC160D-I/ST, 25LC160D-E/SN.
