    產(chǎn)品信息

    The LE25U40CMD is a SPI bus flash memory device with a 4M bit (512K x 8-bit) configuration that adds a high performance Dual output and Dual I/O function. It uses a single 2.5V power supply. While making the most of the features inherent to a serial flash memory device, the LE25U40CMD is housed in an 8-pin ultra-miniature package. All these features make this device ideally suited to storing program in applications such as portable information devices, which are required to have increasingly more compact dimensions. The LE25U40CMD also has a small sector erase capability which makes the device ideal for storing parameters or data that have fewer rewrite cycles and conventional EEPROMs cannot handle due to insufficient capacity.
    • Read/write operations enabled by single 2.5V power supply :
    • 2.3 to 3.6V supply voltage range
    • Operating frequency : 40MHz
    • Highly reliable read/write
    • Number of rewrite times : 100,000 times
    • Small sector erase time : 40ms (typ), 150ms (max)
    • Sector erase time : 80ms (typ), 250ms (max)
    • Chip erase time : 250ms (typ), 2.0s (max)
    • Page program time : 4.0ms/256 bytes (typ), 5.0ms/256 bytes (max)
    • Temperature range : -40 to 85°C
    • Data retention period : 20 years
    • Serial interface :
    • SPI mode 0, mode 3 supported / Dual Output, Dual I/O supported
    • Sector size : 4K bytes/small sector, 64K bytes/sector
    • Small sector erase, sector erase, chip erase functions
    • Page program function (256 bytes / page)
    • Block protect function
    • Status functions : Ready/busy information, protect information
