BR25H040F-2LBH2

Memory IC Overview

The BR25H040F-2LBH2 is a 4kbit (512 x 8) serial EEPROM from ROHM Semiconductor, utilizing an SPI bus interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 10MHz. The device features a write cycle time of 4ms and offers data retention for 100 years with an endurance of 1 million cycles. Designed for industrial applications, it functions between -40°C and +125°C in an SOP-8 package.

Memory IC Feature Summary

• Supports high-speed SPI bus communication for efficient data transfer
• Provides non-volatile storage with extended data retention capabilities
• Engineered for reliable operation across wide industrial temperature ranges

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Automotive electronic modules needing durable memory solutions
• Consumer electronics devices storing configuration data

Memory IC Procurement Notes

Verify the specific suffix '2LBH2' against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for SOP-8 packages. Confirm that the NRND status does not impact long-term supply requirements for your production timeline.

Memory IC Selection Notes

Select this component when a 4kbit capacity is sufficient for application needs. Consider the 2.5V minimum operating voltage if designing for lower power systems compared to 1.7V variants. Verify that the SPI interface speed meets system timing requirements without exceeding the 10MHz limit.

Memory IC Part Context

This part belongs to the BR25H series of automotive-grade and industrial serial EEPROMs. It shares architectural similarities with other members like the BR25H160F-2LBH2 but differs in density. The series emphasizes reliability and durability for harsh environments.

Memory IC Replacement Considerations

Check for BR25H040FJ-5ACE2 as a potential replacement with similar pinout and package, though it offers higher endurance and wider voltage input. Verify availability and updated datasheet specifications before substitution.
