HSCX with SAB 80188 Microprocessor

A system with minimized additional hardware expense can be with a SAB 80188

microprocessor as shown in figure 4.

Figure 4

HSCX with SAB 80188 CPU

The HSCX is connected to the demultiplexed system bus. Data transfer for one serial channel

can be done by the 2-channel on-chip DMA controller of the SAB 80188, the other channel is

serviced by interrupt. Since the SAB 80188 does not provide DMA acknowledge outputs, data

transfer from/to HSCX is controlled via CS, RD or WR address information (A0 … A6) and the

DACKA, DACKB inputs are not used.

This solution supports applications with a high speed data rate in one serial channel with

minimum hardware expense making use of the on-chip peripheral functions of the SAB 80188

(chip select logic, interrupt controller, DMA controller).
