25LC160CT-I/MNY

Overview

The Microchip Technology 25LC160CT-I/MNY is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It utilizes an SPI-compatible serial bus for data access, supporting a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. The device features a 16-byte page write capability and operates within a supply voltage range of 2.5V to 5.5V. It is housed in an 8-lead TDFN package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes hardware write protection via WP pin and software block protection
• Features self-timed erase and write cycles with internal write cycle time of 5 ms max

Applications

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

Procurement Notes

Verify the specific suffix 'CT' indicates cut tape packaging against official Microchip documentation. Confirm the 'I' designation aligns with the required industrial temperature range (-40°C to +85°C). Ensure the 'MN' package code corresponds to the 8-lead TDFN form factor required for your PCB layout.

Selection Notes

Select this component when a 16 Kbit non-volatile memory solution with SPI interface is required. It is suitable for applications needing low power consumption and robust data retention. Consider the 16-byte page size limitation for write operations compared to the 32-byte variant.

Part Context

This part belongs to the 25LC160C/D family of 16 Kbit Serial EEPROMs. The 'C' version specifically denotes a 16-byte page size, distinguishing it from the 'D' version which offers 32-byte pages. All variants share the same core architecture and instruction set.

Replacement Considerations

The 25LC160DT-I/MNY serves as a direct functional substitute, offering identical specifications but with a 32-byte page size instead of 16 bytes.
