Micron M25P40-VMN6TPB Datasheet
The M25P40-VMN6TPB is a high-performance 4 Mbit (512K x 8) NOR Serial Flash memory accessed via an advanced SPI-compatible bus interface. Operating over a versatile supply voltage range of 2.3 V to 3.6 V, it delivers fast data throughput with clock frequencies up to 75 MHz. The memory structure is organized into 8 sectors of 512 Kbits each, enabling efficient page-programming (0.8 ms typical) and sector-erasing (0.6 s typical) operations.
Designed with robust hardware/software write-protection mechanisms (BP0, BP1, BP2 bits) and ultra-low power consumption (1 µA typical in Deep Power-Down mode), the M25P40-VMN6TPB is ideal for industrial control systems, automotive electronics, and embedded networking devices.
The M25P40-VMN6TPB is currently In Stock and ready for immediate shipping at ICHOME. As a leading independent distributor, we ensure 100% authenticity and rapid global delivery.

Supply Chain Insights & Market Trends
Factory lead times for mature 3V SPI NOR Flash parts across franchise channels average 16 to 24 weeks. Due to ongoing fabs re-allocation towards high-density NAND/DRAM, legacy sub-10Mbit SPI Flash series experience periodic spot-market tightness in North American and European production hubs.
Purchasing teams facing urgent BOM shortages or line-stop risks can leverage ICHOME's ready-to-ship inventory, verified origin sourcing, and ISO-compliant ESD packaging to bypass long factory queues.
Cross-Reference & Alternative Parts of M25P40-VMN6TPB
For procurement flexibility during component shortfalls, consider the following functional and drop-in replacements:
M25P40-VMN6P (Micron) — Direct Drop-In Replacement
Comparison: Identical silicon, electrical performance, and SO8 150 mil package. The only variation is packaging format ("P" for Tube vs. "TP" for Tape & Reel).
MX25L4006EM1I-12G (Macronix / MXIC) — Pin-to-Pin Equivalent
Comparison: 4Mbit 3V SPI Flash in SOP-8 150mil package. Supports clock speeds up to 86 MHz and matches the footprint and instruction set for standard SPI read/write commands.
W25Q40EWSNIG (Winbond) — Functional Equivalent
Comparison: 4Mbit SPI Flash in SOIC-8 150mil. Supports Dual/Quad SPI modes. (Note: Verify target system Vcc rail compatibility).
Applications of M25P40-VMN6TPB
The M25P40-VMN6TPB is extensively deployed sectors:
Industrial Automation & Smart Grid: Program memory for PLCs, power meters, drive inverters, and human-machine interfaces (HMIs).
Automotive Systems: Instrument clusters, infotainment bootloaders, and non-critical body electronics (Grade 6 temp range).
Networking & Telecom: Configuration storage for enterprise routers, optical transceivers, and base station modules.
Medical Electronics: Patient monitoring devices requiring robust long-term data retention (20 years).
What Is the Difference Between M25P40-VMN6TPB and M25P40-VMN6P?
Both parts feature identical core specifications: 4 Mbit density, 75 MHz maximum clock rate, 2.3V–3.6V supply range, and -40°C to +85°C industrial operating temperature in an SO8 150 mil package.
The key code breakdowns are:
"TP" vs. "P": TP indicates Tape & Reel carrier packaging (designed for automated high-speed SMT assembly), whereas P denotes standard Tube / Rail packaging.
"B": Represents the 110 nm process technology revision (Process Digit "4" / Process Letter "B"), which is fully backward-compatible with older 150 nm versions while enabling higher 75 MHz clock speeds in the 2.7V–3.6V range.
