25LC160BT-I/MS

Overview

The Microchip Technology 25LC160BT-I/MS is a 16 Kbit Serial Electrically Erasable PROM featuring an SPI-compatible serial bus interface. It utilizes a 2048 x 8-bit organization with a 32-byte page size, characteristic of the 'B' version devices. The component operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz. It is housed in an 8-lead MSOP package and is rated for industrial temperature applications spanning from -40 °C to +85 °C.

Feature Summary

• Supports self-timed erase and write cycles with a maximum duration of 5 ms
• Includes programmable block write protection allowing selection of none, one-quarter, one-half, or all array segments
• Features built-in power-on/off data protection circuitry and a write enable latch mechanism
• Provides a HOLD input pin to pause serial communication without resetting the sequence

Applications

• Microcontroller systems requiring non-volatile data storage via SPI interfaces
• Industrial control environments operating within specified temperature ranges
• Embedded systems needing hardware-level write protection capabilities

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm that the 'I' designation aligns with required industrial operating conditions. Ensure compatibility with system voltage levels between 2.5 V and 5.5 V. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a 16 Kbit capacity with SPI interface is required. The 'B' variant offers a 32-byte page size compared to the 16-byte alternative. Ensure the application environment falls within the -40 °C to +85 °C range. Verify that the MSOP package dimensions fit the available PCB space constraints.

Part Context

This device belongs to the 25XX160A/B family of serial EEPROMs manufactured by Microchip Technology. The family includes variants with different voltage ranges and page sizes. The 'LC' designation indicates operation at 2.5 V minimum, distinguishing it from lower voltage options. The 'T' suffix typically denotes tape and reel packaging for automated assembly.

Replacement Considerations

Public confirmed substitute part numbers include 25LC160DT-E/MS.
