25LC160C-E/MS

Overview

The Microchip Technology 25LC160C-E/MS 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 access. 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 employs a 16-byte page write architecture and includes block write protection capabilities. The component is housed in an 8-lead MSOP package and operates within an extended temperature range of -40°C to +125°C.

Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz
• Features hardware-based write protection via the WP pin and STATUS register bits
• Includes power-on/off data protection circuitry and a write enable latch
• Provides sequential read capability with automatic address pointer increment

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage
• Device identification information logging

Procurement Notes

Verify the specific suffix 'E' indicates the Automotive temperature grade (-40°C to +125°C) rather than Industrial grade. Confirm the 'MS' suffix corresponds to the 8-lead MSOP package type. Ensure compatibility with the required supply voltage range of 2.5V to 5.5V for the target application environment.

Selection Notes

Select this part when an SPI interface EEPROM with automotive-grade temperature stability is required. The 16Kbit capacity suits applications needing moderate non-volatile storage. Consider the 16-byte page size limitation for write operations. Verify that the host microcontroller can support the necessary SPI clock speeds and voltage levels for reliable operation.

Part Context

This component belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs from Microchip Technology. The 'C' designation specifies a 16-byte page size, distinguishing it from the 'D' variant which offers 32-byte pages. The 'L' indicates a 2.5V minimum operating voltage, while 'AA' variants support lower voltages starting at 1.8V.

Replacement Considerations

Public confirmed substitute part numbers: 25LC160DT-I/MNY, 25LC160CT-I/ST, 25LC160C-E/P.
