Detailed Description

128-Mbit (16 MB) serial NOR Flash memory for code and data storage. SPI interface for simple, fast communication with MCUs, SoCs, and FPGAs. 3 V class device (V-range). Compact QFN-8 package for space-constrained designs. Part of the proven M25P family used widely in embedded systems. Ideal for boot code, firmware, parameters, and data logging.

Key Features

128-Mbit capacity (16 MB) for medium-to-large firmware and data sets

Standard SPI serial interface (single I/O), industry-common command set

High-speed read (fast read, continuous read) for quick boot and data access

Page program with typical 256-byte pages for efficient writes

Sector and bulk erase for flexible memory management

Hardware and software protection: WP#, status register protection bits

Deep power-down and low standby current for energy saving

JEDEC ID and standard opcodes for broad compatibility

Industrial operating temperature range (typically -40°C to +85°C)

RoHS-compliant, lead-free packaging; tape-and-reel for automated assembly

Key Advantages

Mature, dependable technology with broad ecosystem support

Easy drop-in integration with most MCU/SoC SPI controllers

Small footprint QFN-8 saves PCB space while keeping performance high

Reliable data retention and endurance suitable for long-life products

Cost-effective solution for firmware storage and field updates

Supports fast, continuous read enabling execute-in-place on systems that support it

Strong protection features reduce risk of accidental overwrite

Packaging

Type: QFN-8 (VFQFPN-8), tape-and-reel (TP) for pick-and-place lines

Material: Molded plastic, lead-free, RoHS compliant

Size: Compact low-profile 8-pin QFN footprint (space-saving on dense boards)

Pin configuration: CS#, SCLK, SI (MOSI), SO (MISO), WP#, HOLD#, VCC, GND

Thermal characteristics: Low thermal resistance typical of QFN; good heat spreading; suitable for industrial ambient ranges

Electrical properties: 3 V supply class (V-range); high-speed SPI (typically up to 75 MHz depending on revision); low standby power; robust ESD and latch-up immunity per industry standards (see datasheet)

Lifecycle

Status: The M25P family is mature and certain variants are NRND or approaching end-of-life in some regions. Availability can vary by date code and package.

Recommended action: Check current supply with Y-IC. If long-term support is required, consider verified alternatives below.
