Product Overview

The Alliance Memory N25Q032A13EF440F is a 32M‑bit (4,194,304 bytes) serial NOR Flash memory built on advanced 65nm NOR technology. Operating from a standard 2.7V to 3.6V power supply, it supports extended SPI, Dual I/O, and Quad I/O protocols, with a maximum clock frequency of 108 MHz. In Quad I/O mode, the device delivers an effective throughput of up to 432 MHz, making it ideal for execute‑in‑place (XIP) applications, fast booting, and code shadowing in embedded systems.

The N25Q032A series is manufactured by Micron Technology and distributed by Alliance Memory, Inc., which specializes in extending the lifecycle of legacy memory products. Housed in a compact 8‑pin UDFN (4x3mm) package (EF440F suffix), it operates over the industrial temperature range of -40°C to +85°C. With 100,000 program/erase cycles and 20‑year data retention, this device provides the endurance and reliability required for industrial control, telecommunications, networking, and consumer electronics.

⚡ SPI Protocol & Performance Modes

Extended SPI (1-1-1)

Single I/O: 108 Mbps
Compatible with all SPI hosts

Dual I/O SPI (1-1-2)

2‑bit read: 216 Mbps
Good speed / pin trade‑off

Quad I/O SPI (1-4-4)

4‑bit read: 432 MHz effective (54 MB/s)
Optimal XIP performance

The N25Q032A supports XIP mode for all three protocols, configurable via volatile or nonvolatile registers, enabling the memory to work in XIP mode directly after power‑on. This feature eliminates the need to copy code from Flash to RAM before execution, reducing boot time and saving system memory.

🔒 Advanced Write Protection & Security

🛡️ Dual‑Level Write Protection
Software write protection is applicable to every 64KB sector via a volatile lock bit. Hardware write protection uses four nonvolatile bits to define the size of the protected area. Additional smart protection configurations are available upon customer request.

🔑 JEDEC Signature & Unique ID
The device features a JEDEC‑standard 2‑byte signature and a 17‑byte read‑only unique ID, which includes two extended device ID bytes and 14 bytes of customizable factory data. This enables device authentication and traceability.

📦 64‑byte One‑Time Programmable Area
An OTP area is available for permanent storage of encryption keys, serial numbers, or manufacturing data. These 64 bytes can be read and programmed using dedicated READ OTP and PROGRAM OTP commands, and can be permanently locked to prevent further modifications.

⏸️ Program/Erase Suspend & Resume
These instructions allow the system to interrupt a long erase or program operation to service a higher‑priority read request, then resume the operation later without data corruption.
