BR25H040FVM-5ACTR

Memory IC Overview

The BR25H040FVM-5ACTR is a 4Kbit (512 x 8 bit) serial EEPROM from the BR25H-5AC series, designed for automotive applications. It features an SPI bus interface with a maximum input frequency of 20 MHz and supports voltage ranges from 1.7 V to 5.5 V. The device operates within a temperature range of -40°C to 125°C and is AEC-Q100 Grade 1 qualified. Key electrical parameters include a maximum standby current of 10 μA, a write cycle time of 3.5 ms, and endurance of 4 million cycles. Data retention is specified at 100 years.

Memory IC Feature Summary

• Automotive-grade reliability with AEC-Q100 Grade 1 qualification and support for functional safety analysis.
• High-speed SPI bus interface supporting CPOL/CPHA modes (0,0) and (1,1) for efficient data transfer.
• Advanced write protection mechanisms including software-selectable block locking and power-on write prohibition.
• Integrated identification page and auto-increment read functions to streamline system integration.

Memory IC Applications

• Automotive electronic control units requiring durable non-volatile storage
• Industrial systems demanding high-temperature operation up to 125°C
• Data logging modules needing long-term data retention

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm that the component meets the required AEC-Q100 Grade 1 standards for your target automotive application. Ensure compatibility with the 1.7V to 5.5V supply voltage range and SPI protocol settings before finalizing procurement specifications.

Memory IC Selection Notes

Select this component for designs requiring robust automotive certification and wide operating temperatures. The 4Kbit capacity suits small configuration storage needs. Consider the MSOP8 package size for space-constrained PCB layouts. Verify that the 20 MHz SPI speed aligns with the host microcontroller's capabilities.

Memory IC Part Context

This part belongs to the BR25H-5AC series, which offers various densities from 2Kbit to 1Mbit. The series is characterized by high-speed writing and extended data retention, making it suitable for critical automotive memory tasks. The BR25H040 variant specifically provides 4Kbit density in a compact surface-mount package.

Memory IC Replacement Considerations

BR25H040FVT-5ACE2 is a confirmed substitute with the same pinout and package but uses TSSOP-B8 instead of MSOP8. BR25H04ANUX-5ACTR is another alternative within the same series offering similar functionality in a different package format.
