25LC160CT-I/MS

Overview

The Microchip Technology 25LC160CT-I/MS is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It operates via an SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V, reducing to 5 MHz at 2.5V–4.5V. The device supports a 16-byte page size and functions within a supply voltage range of 2.5V to 5.5V. It utilizes an 8-lead MSOP package and maintains an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports sequential read operations with automatic address pointer incrementation across the memory array.
• Includes built-in write protection mechanisms such as a write enable latch and programmable block protection bits.
• Features a hold pin that allows suspension of serial communication without resetting the current sequence.

Applications

• Data storage for configuration parameters in microcontroller systems
• Logging operational data in industrial monitoring equipment
• Storing calibration constants in embedded sensor interfaces

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm the 'I' designation aligns with required industrial temperature specifications. Ensure the 'C' variant matches the necessary 16-byte page size requirement for the target application design.

Selection Notes

Select this component for applications requiring low-power CMOS technology and robust data retention capabilities. Consider the 16-byte page size limitation for write operations compared to the 32-byte alternative. Evaluate the MSOP package dimensions against available board space constraints during the layout phase.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. These devices are designed for direct interface with SPI ports found in popular microcontroller families. The family includes variants with different page sizes and voltage ranges to suit diverse system requirements.

Replacement Considerations

The 25LC160DT-I/MS serves as a functional substitute within the same family, offering identical electrical characteristics but utilizing a 32-byte page size instead of 16 bytes. Designers must verify software compatibility regarding page boundary handling when substituting this part.
