概览

LE25U40CMC 是一款 SPI 总线闪存器件，带有 4MB （512K x 8 位）配置，增加了一个高性能双输出和双 I/O 功能。它使用 2.5v 单电源。LE25U40CMC 尽管可以在串行闪存器件内部提供大多数功能，但仍然采用了 8 引脚超微型封装。所有这些特性都使得此器件适用于存储便携信息设备等应用中的程序，在此类设备中，尺寸要求越来越紧凑。LE25U40CMC 具有小扇区擦写功能，使得该器件适用于存储具有更少重写次数且传统 EEPROM 因容量不足而无法处理的参数或信息。

  • Small sector erase, sector erase, chip erase functions
  • Page program function (256 bytes / page)
  • Block protect function
  • Highly reliable read/write
  • Status functions : Ready/busy information, protect information
  • Data retention period : 20 years
