25LC160BT-E/ST

Overview

The Microchip Technology 25LC160BT-E/ST is a 16 Kbit (2048 x 8-bit) Serial Electrically Erasable PROM. It utilizes an SPI-compatible serial bus for data access, supporting a maximum clock frequency of 10 MHz. The device features a 32-byte page size and operates within a supply voltage range of 2.5 V to 5.5 V. It is housed in an 8-lead TSSOP package and supports an extended temperature range from -40°C to +125°C.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes hardware write protection via dedicated pin and software control bits
• Features self-timed erase and write cycles with internal timing generation
• Provides hold functionality to pause serial communication without resetting the sequence

Applications

• Microcontroller system data storage
• Industrial control applications requiring extended temperature operation
• Automotive electronic systems
• Embedded devices needing non-volatile parameter retention

Procurement Notes

Verify the specific suffix 'E' indicates automotive grade qualification (-40°C to +125°C). Confirm the 'B' designation corresponds to the 32-byte page size variant. Ensure the 'ST' suffix matches the required 8-lead TSSOP package type. Cross-reference the datasheet revision to confirm compatibility with current manufacturing standards.

Selection Notes

Select this component when an SPI interface is preferred over I2C or Microwire protocols. Choose the 'E' grade version specifically for environments exceeding standard industrial temperatures. Verify that the 32-byte page buffer aligns with the application's write efficiency requirements compared to the 16-byte 'A' version.

Part Context

This part belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants with different voltage ranges, page sizes, and temperature grades. The 25LC160 series specifically denotes low-voltage CMOS technology compatible with 2.5V to 5.5V logic levels.
