PCF8594C-2是一款浮动门控电可擦可编程只读存储器(EEPROM),具备4 kbits (512 x 8位)非易失性存储器。通过使用内部冗余存储代码,对单个位元错误具有容错功能。相比传统的EEPROM,此功能显著提升了可靠性。由于使用全CMOS技术,所以功耗很低。使用电压倍增器片上生成编程电压。
通过串行I²C总线接收和发送数据字节。可将最多四个PCF8594C-2器件连接至I²C总线。通过两个地址输入(A1和A2)完成芯片选择。
内部执行E/W周期的定时,所以无需外部组件。引脚7编程时间控制(PTC)必须连接至VDD或保持开路。也可选择使用外部时钟对E/W周期的时长进行定时。
部件编号包含: PCF8594C-2T.
