SCANPSC100F集成电路（IC）的控制器规格书PDF中文资料

General Description

The SCANPSC100F is designed to interface a generic parallel processor bus to a serial scan test bus. It is useful in improving scan throughput when applying serial vectors to system test circuitry and reduces the software overhead that is associated with applying serial patterns with a parallel processor.
