概览

CAT28C512 是一款快速、低功耗，仅 5.0 V 的 CMOS 并行 EEPROM，组织为 64k x 8 位。它仅需简单的接口即可实现系统内编程。片上地址和数据锁存、带自动清除的自计时写循环，以及 VCC 通电/断电写保护，这些功能消除了附加的计时和保护硬件。数据轮询和切换状态位发送自计时写循环的开始和结束信号。另外，CAT28C512 具有硬件和软件写保护特性。CAT28C512 采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 100 年。该器件采用 JEDEC 认证的 32 引脚 DIP、PLCC 或 TSOP 封装。
