IS25LX128-JHLE

The IS25LX128-JHLE is a 128Mbit serial NOR Flash memory device from ISSI, Integrated Silicon Solution Inc featuring an advanced Octal SPI interface for high-speed data transfer. Organized as 16M x 8, this non-volatile memory delivers fast read performance at up to 133MHz clock frequency, making it ideal for embedded systems requiring rapid code execution and data storage. With support for both traditional SPI and high-performance Octal I/O modes, this Flash memory provides design flexibility for applications ranging from industrial controllers to consumer electronics.

Operating across an extended temperature range of -40°C to 105°C and powered by a standard 2.7V to 3.6V supply, the IS25LX128-JHLE offers reliable performance in demanding environmental conditions. The compact 24-TFBGA (6x8) package minimizes PCM footprint while the Octal interface reduces pin count compared to parallel Flash alternatives.

Key Features

• High-Density Storage - 128Mbit (16 Megabyte) capacity provides ample space for firmware, configuration data, and data logging in embedded applications.
• Octal SPI Interface - Eight-bit wide SPI interface with support for up to 133MHz clock frequency enables faster data throughput compared to standard Quad SPI implementations, reducing boot times and improving system responsiveness.
• Dual Interface Compatibility - Supports both traditional SPI modes and Octal I/O operation, allowing designers to optimize the interface based on performance requirements and pin availability.
• Extended Temperature Range - Qualified for -40°C to 105°C ambient operation, ensuring reliable data retention and access in industrial, automotive, and outdoor applications.
• Wide Voltage Range - 2.7V to 3.6V supply voltage accommodates both 3.3V and lower-voltage system designs, simplifying power supply design.
• Compact TFBGA Package - 24-ball thin fine-pitch ball grid array (6x8mm) minimizes board space while providing excellent thermal performance.
