The 3DFS256M04VS1740 is a SPI Flash NOR. The memorie is organized respectively in 2 banks of 128 Mbit each with distinct chip enable CEn# control. Each memory requires only a single 3.0 V power supply for both read and write functions.
Thanks to dual SPI and quad SPI interfaces, and Fast Read mode feature, these serial NOR Flash memory can achieve highthroughput (up to 133 MHz), which makes them a perfect fit for high-speed circuit applications. They are highly suitable for code storage in embedded systems.
Radiation Tolerance
The memory module is available in a small dimension (SOP 20) package, optimized for minimal PCB real estate for Space applications.
Its memory density, its guaranteed data retention, its SEL immunity, SEE mitigation operations and space-qualified technology make it the ideal memory device for SRAM-based FPGA configuration. The device has also the capability to be easily switched-off after the boot code has been loaded to save the application power.
