IS25WP128-JBLE

Overview

The IS25WP128-JBLE is a 128Mbit (16MB) Serial Flash memory device featuring a high-speed SPI interface with Quad I/O and QPI support. It operates on a low-voltage 1.8V power rail, supporting clock speeds up to 133 MHz and Double Transfer Rate (DTR) for enhanced throughput. This memory is designed for high-performance applications requiring fast boot times and efficient data storage in a compact 8-pin package.

Why Choose This Part

This device offers a high-speed 133 MHz clock frequency and Quad SPI support, significantly reducing latency for read operations compared to standard SPI flash. Its wide operating temperature range and low-voltage operation make it highly versatile for modern energy-efficient designs.

Applications

Getting Started

To integrate this flash, ensure your host MCU or FPGA supports 1.8V logic levels on the SPI bus. Implementation typically involves using a standard SPI or QSPI driver, paying close attention to the instruction set for Quad I/O and DTR modes to maximize performance. Most major RTOS and filesystem drivers like LittleFS support these ISSI flash variants.
