Specific Applications
HSCX with SAB 8051 Microcontroller
For cost-sensitive applications, the HSCX can be interfaced with a small SAB 8051
microcontroller system (without DMA support) very easily as shown in figure 3.
Figure 3
HSCX with 8051 CPU
Although the HSCX provides a demultiplexed bus interface, it can optionally be connected
directly to the local multiplexed bus of SAB 8051 because of the internal address latch function
(via ALE, compatibility to SAB 82520 HSCC).
The address lines A0 … A6 must be wired externally to the data lines D0 … D6 (direct
connection) in this case.
Intel bus mode is selected connecting IM1 pin to low (
