Overview

The IS25LP040E-JNLE is a 4Mbit (512 KB) Serial Flash memory designed for high-performance embedded systems. It supports Standard, Dual, and Quad SPI as well as QPI and Double Transfer Rate (DTR) modes, reaching clock speeds up to 104 MHz. This NOR flash is optimized for low power consumption, drawing only 6 mA during active reads and 17 uA in standby mode.

Why Choose This Part

It offers exceptional flexibility with support for SFDP and multiple I/O modes including Quad SPI and QPI for high throughput. The device includes advanced security features such as a 128-bit unique ID and a 4x256-byte OTP security area. Its wide voltage range of 2.3V to 3.6V makes it compatible with most modern 2.5V and 3.3V logic systems.

Applications

Execute-in-Place (XIP) Storage
Utilizes Quad I/O and QPI modes to allow microcontrollers to execute code directly from flash memory, reducing the need for internal SRAM.
Firmware Backup
Reliable non-volatile storage for bootloaders and system firmware in industrial and consumer electronics.
Data Logging
Small footprint storage for sensor data and configuration parameters, utilizing its 256-byte programmable pages.

Getting Started

To interface with the IS25LP040E-JNLE, configure your microcontroller's SPI peripheral for Mode 0 or Mode 3. Use the Standard SPI instruction set for initial configuration before switching to Quad SPI for higher performance. Review the SFDP tables to automatically discover device characteristics and timing parameters during system initialization.
