1 Mb 批量擦除闪存

概览

CAT28F010 是一款高速 128k x 8 位可电子擦除和可重编程闪存,适用于需要系统内或售后代码更新的应用。完整内存内容的电子擦除通常可在 0.5 秒内实现。它可与标准的 EPROM 和 EEPROM 器件实现引脚和读取计时兼容。编程和擦除通过运算和验证算法执行。指令使用两次写入循环方案,通过 I/O 总线输入。写入操作期间,地址和数据进行锁存,以释放 I/O 总线和地址总线。CAT28F010 使用安森美半导体先进的 CMOS 浮动门极工艺制造。它可耐受 100,000 个编程/擦除循环,数据保留期为 10 年。该器件采用 JEDEC 认证的 32 引脚塑料 DIP、32 引脚 PLCC 或 32 引脚 TSOP 封装。
