Product details
Overview
AT25XV041B-MHV-Y from Renesas Electronics is a 4-Mbit serial SPI Flash memory IC operating from 1.65 V to 4.4 V, supporting Dual-I/O read at up to 85 MHz, with 7.5 ns clock-to-output delay and flexible erase granularity (256-byte page, 4/32/64-kByte blocks). It enables code shadowing, OTA firmware updates, and secure local data storage in battery-powered IoT edge nodes.
For engineers reviewing the AT25XV041B-MHV-Y datasheet, AT25XV041B-MHV-Y pinout, AT25XV041B-MHV-Y application, or AT25XV041B-MHV-Y equivalent, key selection criteria include ultra-low deep power-down current (200 nA), OTP security register (128 bytes), hardware write protection via WP pin, and JEDEC-standard ID read capability.
Technical Context
The AT25XV041B-MHV-Y implements a dual-I/O SPI interface compliant with Modes 0 and 3, enabling two-bit-per-clock read throughput without requiring quad I/O pins. Its internal architecture includes dedicated SRAM data buffers, Y/X-decoders, and control logic that supports concurrent status polling and active interrupt signaling during program/erase operations.
It features a hierarchical erase structure-256-byte pages for fine-grained data logging, uniform 4-kByte blocks for firmware segments, and 32/64-kByte blocks for bulk code updates-optimized for mixed code+data storage. Protection is enforced via both software-configurable sector registers and hardware-controlled locking through the WP pin.
Key Specifications

FAQ
What is the minimum operating voltage for the AT25XV041B-MHV-Y?
The AT25XV041B-MHV-Y operates down to 1.65 V, enabling direct compatibility with single-cell lithium batteries and energy-harvesting sources. This low-voltage capability allows the AT25XV041B-MHV-Y to remain functional during brown-out conditions where other Flash devices would reset or become unreliable, ensuring robust boot and data integrity in portable and remote systems.
Does the AT25XV041B-MHV-Y support Quad-I/O mode?
No, the AT25XV041B-MHV-Y supports only standard SPI and Dual-I/O modes (using SI and SO pins as I/O0 and I/O1). It does not implement Quad-I/O functionality. The AT25XV041B-MHV-Y achieves high read throughput via Dual-I/O at up to 85 MHz, balancing performance and pin count efficiency without requiring additional I/O lines.
How is the 128-byte OTP security register structured in the AT25XV041B-MHV-Y?
The AT25XV041B-MHV-Y's 128-byte OTP security register consists of 64 bytes factory-programmed with a unique device identifier and 64 bytes user-programmable for keys or custom data. Once written, OTP bytes cannot be erased or rewritten, making the AT25XV041B-MHV-Y suitable for secure boot, anti-counterfeiting, and disposable consumable authentication schemes.
What erase block sizes does the AT25XV041B-MHV-Y support?
The AT25XV041B-MHV-Y supports four erase granularities: 256-byte pages for fine-grained data logging, and uniform 4-kByte, 32-kByte, and 64-kByte blocks for firmware and configuration updates. This hierarchy allows developers to optimize wear leveling and minimize erase time-critical for applications like OTA updates and sensor data buffering where endurance and latency matter.
Can the AT25XV041B-MHV-Y be used in industrial temperature environments?
Yes, the AT25XV041B-MHV-Y is rated for the full industrial temperature range of –40°C to +85°C and complies with RoHS and green packaging standards. Its guaranteed 20-year data retention and 100,000 program/erase cycles make the AT25XV041B-MHV-Y appropriate for deployment in harsh environments such as factory automation controllers, outdoor metering, and transportation infrastructure.
