IS25WX256-JHLA3-TR

The IS25WX256-JHLA3-TR is a 256-megabit serial NOR flash memory with Octal SPI interface, organized as 32M x 8 bits. This high-performance non-volatile storage solution delivers up to 200MHz clock frequency, enabling data throughput of 400MB/s in Octal DTR mode. Designed for embedded systems requiring fast boot times and code execution, it operates across an extended temperature range of -40°C to 125°C (TA), making it suitable for both consumer and industrial applications.

Key Features

• High-Density Storage - 256Mbit (32MB) of non-volatile flash memory organized as 32M x 8, providing ample space for firmware, code execution, and data storage in embedded designs.
• Octal SPI Interface - Supports Octal I/O SPI with up to 200MHz clock frequency, delivering significantly higher bandwidth than traditional Quad SPI for faster boot and read operations.
• Low Operating Voltage - 1.7V to 2V supply voltage range reduces power consumption and aligns with modern low-power system designs.
• Extended Temperature Range - Operates reliably from -40°C to 125°C (TA), ensuring performance across industrial and automotive-adjacent environments.
• Compact Package - 24-pin TFBGA (6x8mm) footprint minimizes board space requirements while maintaining manufacturability.

Typical Applications

• Embedded Systems - This flash memory serves as boot code storage for microcontrollers and processors, where the Octal SPI interface enables fast system initialization and execute-in-place (XIP) capabilities.
• Industrial Control Systems - The extended temperature rating makes it suitable for storing firmware and configuration data in PLCs, motor drives, and industrial IoT devices that must operate reliably in harsh environments.
• Networking Equipment - High-speed Octal SPI access supports firmware storage in routers, switches, and access points where rapid boot times and firmware updates are critical to network uptime.
• Consumer Electronics - The 256Mbit capacity and compact TFBGA package fit space-constrained designs like smart home devices, wearables, and portable instruments requiring non-volatile program storage.
• Automotive Infotainment - Operating across wide temperature ranges, this flash memory handles code storage for dashboard displays, telematics modules, and ADAS systems where reliability is essential.

Unique Advantages

• Reduced Boot Time: Octal SPI at 200MHz delivers up to 2x faster read speeds compared to Quad SPI, accelerating system initialization and improving user experience.
• Simplified BOM: Single-chip integration of 256Mbit eliminates the need for multiple smaller flash devices, reducing component count and assembly costs.
• Design Flexibility: Wide voltage range (1.7V to 2V) allows compatibility with both 1.8V and newer ultra-low-power processor families without level shifters.
• Enhanced Reliability: Extended temperature operation (-40°C to 125°C) ensures consistent performance across diverse deployment environments without requiring thermal management.
• Board Space Optimization: The 6x8mm TFBGA package provides high density in a small footprint, freeing up board real estate for additional features or size reduction.
• Future-Proof Interface: Octal SPI support positions designs for next-generation processor interfaces while maintaining backward compatibility with standard SPI modes.
