4位单片机

MOS集成电路

该

PD75068是75X系列的第4位单芯片微型计算机中的一员。

的最小指令执行时间

PD75068的CPU是0.95

秒。除了这种高速

能力，该芯片包含一个A / D转换器和配料高性能的功能，诸如串行

总线接口（ SBI ）函数符合NEC标准格式，提供了强大的功能和高

性能价格比。该

PD75068 （A ）是一种高可靠性版本

PD75068.

NEC还提供了适用于系统的小规模生产或评估样片的PROM版本

发展。该

PD75P068是PROM版本的

PD75064 ， 75066 ， 75068 ，以及

PD75P068(A)

是，对于

PD75064 （ A） ， 75066 （ A） ， 75068 （ A） 。

详细的功能说明将在下面的文档中描述。请务必阅读本
