25C160T/SN

Memory IC Overview

The Microchip Technology 25C160T/SN is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM accessed via an SPI-compatible serial bus. It operates within a voltage range of 4.5V to 5.5V with a maximum clock frequency of 3 MHz. The device supports industrial and automotive temperature ranges (-40°C to +85°C and -40°C to +125°C). Key electrical characteristics include a typical standby current of 500 nA, a maximum write current of 3 mA, and a maximum write cycle time of 5 ms. It features a 16-byte page buffer and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports block write protection for none, 1/4, 1/2, or all of the memory array
• Includes built-in power on/off data protection circuitry and a write enable latch
• Features a dedicated hold pin to pause serial communication without resetting the sequence
• Provides hardware write protection via the WP pin controlled by the Status register

Memory IC Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage
• Device identification information logging

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging and 'SN' denotes the 8-lead SOIC package. Confirm the temperature grade matches the required operational environment, as the base part number covers both Industrial and Automotive grades. Ensure the supply voltage aligns with the 4.5V to 5.5V specification. Check for any specific revision history or errata sheets associated with this datasheet version before finalizing procurement.

Memory IC Selection Notes

Select this component when a 5V-only SPI EEPROM is required for automotive or industrial applications. It is suitable for designs needing hardware write protection and sequential read capabilities. Consider the 16-byte page size for write efficiency. Note that this family is not recommended for new designs; verify if newer alternatives like the 25LC160A/B are more appropriate for long-term projects.

Memory IC Part Context

This device belongs to the 25XX160 family of 16 Kbit Serial EEPROMs from Microchip Technology. It shares architectural similarities with the 25AA160 and 25LC160 but is distinguished by its 4.5V to 5.5V operating voltage range. The 'T' suffix specifies tape and reel packaging, while 'SN' identifies the narrow SOIC package. The datasheet explicitly notes that this specific generation is not recommended for new designs.
