25LC160CT-E/ST

Overview

The Microchip Technology 25LC160CT-E/ST is a 16 Kbit Serial Electrically Erasable PROM featuring a 2048 x 8-bit organization. It utilizes an SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device operates within a voltage range of 2.5 V to 5.5 V and supports industrial temperature ranges from -40°C to +85°C. It employs a 16-byte page size for write operations and is housed in an 8-lead TSSOP package.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes built-in hardware write protection via WP pin and STATUS register bits
• Features self-timed erase and write cycles with automatic completion
• Provides sequential read capability with automatic address pointer increment

Applications

• Microcontroller data storage systems
• Industrial control applications requiring non-volatile memory
• Automotive electronic modules operating at extended temperatures
• Embedded systems needing low-power EEPROM solutions

Procurement Notes

Verify the specific suffix 'CT' indicates tape and reel packaging configuration. Confirm the 'E' designation aligns with automotive temperature specifications if required by your design. Ensure the TSSOP-8 footprint matches your PCB layout constraints. Cross-reference the datasheet revision to confirm electrical characteristics match your system requirements.

Selection Notes

Select this component when an SPI interface is preferred over parallel architectures. Choose the 'C' version for 16-byte page writes rather than the 'D' version's 32-byte pages. Opt for the 'E' grade if operation beyond standard industrial limits is necessary. Consider the TSSOP package for surface-mount assembly efficiency compared to through-hole alternatives.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs. It shares core functionality with variants like the 25LC160C-I/ST but differs in temperature rating and packaging format. The 'L' variant typically denotes lower voltage support starting at 2.5V, distinguishing it from the 'AA' series which supports 1.8V inputs.

Replacement Considerations

The M95160-DWDW4TP/K is documented as a substitute option.
