    产品信息

    The LE25U20AFD is a serial interface-compatible flash memory device with a 256K x 8-bit configuration. It uses a single 2.5 V power supply. While making the most of the features inherent to a serial flash memory device, the LE25U20AFD is housed in an 8-pin ultra-miniature package. These features make this device ideally suited to storing program codes in applications such as portable information devices, which are required to have increasingly more compact dimensions. Moreover, by using the small sector erase function this product is also suitable for the parameter or the date storage usage with comparatively little rewriting times that becomes acapacity shortage in EEPROM.
    • Read / write operations enabled by single 2.5 V power supply :
    • 2.30 to 3.60 V supply voltage range
    • Operating frequency : 30 MHz
    • Temperature range : -40 to 85°C
    • Serial interface : SPI mode 0, mode 3 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
    • Highly reliable read/write
    • Number of rewrite times : 100,000 times
    • Small sector erase time : 40 ms (typ), 150 ms (max)
    • Sector erase time : 80 ms (typ), 250 ms (max)
    • Chip erase time : 250 ms (typ), 1.6 s (max)
    • Page program time : 4.0 ms/256 bytes (typ), 5.0 ms/256 bytes (max)
    • Data retention period : 20 years
