Product Overview
N25Q256A11EF840F is a high-performance 256-Mbit low-voltage Serial NOR Flash from Micron Technology. Built on 65nm NOR architecture, this IC supports single, dual and quad SPI interfaces as well as XIP (Execute-In-Place) function with maximum clock speed up to 108MHz. Equipped with flexible 4KB subsector and 64KB sector erase structure, it protects critical firmware with hardware & software write protection. Packaged in VDFPN-8 (8mm × 6mm), ROHS-compliant, it provides reliable high-density non-volatile storage for communication devices, automotive systems, network equipment and wearable electronics.
Core Advantages
Ultra-Low Power 1.8V Operation
Operating at 1.7V to 2.0V (typical 1.8V), it reduces operating and standby power consumption compared with 3V flash chips, extending battery life for portable electronic devices.
High-Speed Quad-SPI & XIP Capability
Supports high-speed readout under Single/Dual/Quad SPI modes and XIP function, enabling microcontrollers to run code directly from flash without additional SRAM buffer.
Flexible Erase & Sector Management
Supports 4KB subsector and 64KB sector erase, convenient for parameter storage, remote firmware upgrade and efficient storage management.
Robust Hardware Security & Compact Form Factor
Features register lock, WP pin hardware write protection and sector protection. The compact 24-ball V-LBGA package saves PCB layout space for high-density SMT designs.

Frequently Asked Questions
Q1: What is the operating voltage difference between N25Q256A11EF840F and N25Q256A13 variants?
A: The “11” stands for 1.8V nominal supply (1.7V~2.0V). The “13” version uses standard 3.0V voltage (2.7V~3.6V).
Q2: What does the suffix “F” in the part number mean?
A: The “F” indicates Tape & Reel packaging, suitable for automated SMT production.
Q3: Can N25Q256A11EF840F work with standard single SPI controllers?
A: Yes. It is fully backward compatible with single-bit SPI Mode 0/3, also supports Dual and Quad SPI.
Q4: What temperature range does this flash support?
A: Industrial grade -40°C ~ +85°C, stable under harsh working environments.
Q5: What is the data retention time of this NOR Flash?
A: Minimum 20 years data retention under rated operating conditions.
Q6: How many write and erase cycles can the chip withstand?
A: Up to 100,000 erase/write cycles for each sector.
Q7: Does this component support XIP (Execute In Place) operation?
A: Yes, XIP function allows MCU to directly run firmware code stored inside the flash.
