25C160T-E/SN

Memory IC Overview

The Microchip Technology 25C160T-E/SN is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM featuring an SPI-compatible interface. It operates within a supply voltage range of 4.5 V to 5.5 V with a maximum clock frequency of 3 MHz. The device supports industrial and automotive temperature ranges, specifically -40°C to +125°C for the 'E' grade. It utilizes low-power CMOS technology with typical standby current of 500 nA and read current of 500 µA. The component is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Integrated block write protection allowing selective array segmentation
• Hardware write-protect pin combined with status register control
• Power-on/off data protection circuitry prevents inadvertent writes
• Hold function capability allows serial communication suspension

Memory IC Applications

• Automotive electronic systems requiring extended temperature operation
• Industrial equipment needing reliable non-volatile data storage
• Microcontroller-based systems utilizing SPI bus interfaces

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging and 'SN' denotes the SOIC package. Confirm the 'E' suffix corresponds to the -40°C to +125°C automotive temperature rating. Ensure the datasheet revision matches the required specifications as this product family may have updates or replacements.

Memory IC Selection Notes

Select this component when a 5V-only supply system requires 16 Kbit of EEPROM storage. The automotive temperature grade is suitable for harsh environments. Consider the page write limit of 16 bytes per cycle. Verify that the SPI timing requirements align with the host controller's capabilities.

Memory IC Part Context

This part belongs to the 25XX160 family alongside 25AA160 and 25LC160 variants. It shares the same memory architecture but differs in voltage and temperature specifications. The 'T' suffix designates tape and reel packaging for automated assembly. The 'SN' suffix identifies the narrow plastic small outline package.

Memory IC Replacement Considerations

Microchip recommends using 25AA160A/B or 25LC160A/B for new designs. No direct official substitute part numbers are listed for this specific automotive variant in the provided documentation.
