N25Q512A83GSFA0F (referred to as N25Q) is a product of Micron Technology Inc. It belongs to the family of Serial NAND Flash service memory. It is suitable for a wide range of applications and is widely used in consumer electronics, industrial and automotive applications.

Introduction

The N25Q is a single-die serial NAND Flash memory device and the most advanced solution in the family of Serial NAND Flash memory. It features a 96-bit wide random-accessible data interface, utilizing serial double data rate (DDR) techniques. N25Q also features flexible control of write protection and data programming, as well as an easy-to-configure and unique block protection architecture.

The N25Q is offered in a variety of densities, ranging from 1 Gbit up to 16 Gbit. It is available in the traditional standard 8 x 20 mm package as well as in mini-TFBGA and WLP packaging solutions. The 1 Gbit and 2 Gbit devices are available in the standard 8 x 20 mm packages and the 8 Gbit, 16 Gbit and 32 Gbit devices are available in mini-TFBGA and WLP packages. The N25Q also supports a 5 V supply voltage, allowing flexibility for a wide range of applications.

Application Field

The N25Q is ideal for applications needing fast, reliable and cost effective non-volatile memory. It is a great solution for applications such as automotive infotainment, industrial control systems, internet of things (IoT) devices, audio, video and mobile devices, multi-function printers (MFPs), ad flash storage solutions. It is also suitable for medical, consumer, computer and industrial applications.

It has the ability to withstand operating temperature up to 105°C. It also features high write endurance of more than 10,000 cycles. This makes it perfect for rugged applications and use in automotive infotainment and mission-critical industrial designs.

Working Principle

The N25Q utilizes a 96-bit wide serial interface. The N25Q can be configured as either a synchronous or asynchronous device. As a synchronous device, it supports double data rate (DDR) mode and can provide a maximum of 66 MHz access frequency. As an asynchronous device, it operates at a maximum of 33 MHz.

The control interface of the N25Q comprises a Command Register (CR), an Address Register (AR) and a Data Register (DR). The CR consists of one register that holds command codes and other status information. The AR holds the address being used by the device and includes three registers that together accommodate 48 bits of memory address. The DR holds the data being transmitted and consists of two 8-bit registers. The N25Q also features an external write protection pin (WP#) that can be used to protect a portion of the N25Q memory array from being written to.

The N25Q also features an on-board Error Correction Code (ECC) engine for data protection. The ECC engine is designed to detect and correct single-bit errors as well as detect double-bit errors. This ensures data accuracy even when the N25Q is subject to harsh environmental conditions or operating temperature extremes.

Conclusion

The N25Q is the most advanced solution in the family of Serial NAND Flash memory. With its 96-bit wide random-accessible data interface, support for multiple voltage levels and powerful on-board ECC engine, it is ideal for a variety of applications. It is well suited for use in automotive infotainment, industrial control systems and other mission-critical environments. With its comprehensive protection features and high write endurance, the N25Q is the perfect choice for any application requiring high levels of reliability and performance.
