25LC160BT-I/SN

Overview

The Microchip Technology 25LC160BT-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 for access. The device supports a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. It operates within a supply voltage range of 2.5V to 5.5V and includes a 32-byte page buffer. The component is housed in an 8-lead MSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed serial communication via a standard SPI interface with a maximum clock frequency of 10 MHz.
• Features a 32-byte page write capability for efficient data storage operations.
• Includes built-in hardware and software write protection mechanisms, including block protection and power-on data protection.
• Provides a Hold function that allows the host to pause serial communication without resetting the sequence.

Applications

• Microcontroller systems requiring non-volatile data storage
• Industrial control applications operating in harsh environments
• Embedded systems needing secure parameter retention

Procurement Notes

Verify the specific suffix 'BT' against official documentation to confirm it denotes tape-and-reel packaging or specific manufacturing lot attributes, as datasheets primarily list standard suffixes like SN or MS. Confirm the 'I' designation strictly corresponds to the -40°C to +85°C industrial temperature range. Ensure compatibility with the required 2.5V to 5.5V supply voltage before integration.

Selection Notes

Select this component when a 16 Kbit capacity is required with SPI interface compatibility. The 'B' version indicates a 32-byte page size, which differs from the 16-byte page size of the 'A' version. The 'MSOP' package offers a compact surface-mount solution suitable for space-constrained designs. Ensure the application environment remains within the specified industrial temperature limits.

Part Context

This part belongs to the 25XX160A/B family of 16 Kbit Serial EEPROMs from Microchip Technology. The family shares common electrical characteristics and instruction sets but varies by voltage range (LC vs AA), page size (A vs B), and physical package type. The 25LC160 variant specifically supports a 2.5V minimum supply voltage.

Replacement Considerations

Public confirmed substitutes include 25LC160BT-E/MS and 25LC160BT-I/ST. Verify pinout compatibility and ensure the replacement matches the required 32-byte page size and industrial temperature rating.
