25LC160CT-I/SN

Overview

The Microchip Technology 25LC160CT-I/SN 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. 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 size for write operations. The component is housed in an 8-lead TSSOP package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports sequential read operations and self-timed erase/write cycles with a maximum duration of 5 ms.
• Includes built-in write protection mechanisms such as power-on/off data protection, a write enable latch, and a dedicated write-protect pin.
• Features a hold pin that allows communication pausing without resetting the serial sequence, facilitating higher priority interrupt servicing.

Applications

• Data storage in microcontroller systems requiring non-volatile memory
• Industrial control applications operating within specified temperature ranges
• Embedded systems utilizing SPI bus interfaces

Procurement Notes

Verify the specific suffix 'CT' indicates cut tape packaging rather than standard reel quantities when sourcing. Confirm the 'I' designation aligns with industrial temperature requirements. Ensure the TSSOP package dimensions match the target PCB footprint. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with current design specifications.

Selection Notes

Select this component for designs requiring low-power CMOS technology with high reliability. Consider the 16-byte page size limitation for write operations compared to 32-byte alternatives. Evaluate the 10 MHz clock speed against system timing constraints. Verify compatibility with the host microcontroller's SPI mode and voltage levels before integration into the final assembly.

Part Context

This part belongs to the 25XX160C/D family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'LC' variant specifies a 2.5V to 5.5V operating voltage range. The 'I' suffix denotes the industrial temperature grade. The 'SN' suffix identifies the 8-lead SOIC package, while 'CT' typically refers to cut tape packaging variations within the distribution channel.
