    產(chǎn)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

    型號制造商描述購買
    LE25U20AFD-AHONLE25U20AFD 是一款可兼容串行接口的閃存器件，帶有 256K × 8 位配置。它使用 2.5 V 單電源。在充分利用串行閃存設(shè)備固有特性的同時，LE25U20AFD 采用 8 引腳超小型封裝。這些功能均使得此器件適用于便攜信息設(shè)備等應(yīng)用中的存儲程序代碼，在此類應(yīng)用中，尺寸越來越緊湊。而且，通過使用小扇區(qū)擦除功能，此產(chǎn)品還適用于參數(shù)和日期存儲用途，并且具有相對較小的重寫時間，而這點是 EEPROM 的能力短板。 立即購買
