17. Application information
17.1 Typical interface circuit
17.2 Interfacing a ISP1160 to a SH7709 RISC processor
This section shows a typical interface circuit between the ISP1160 and a RISC
processor. The Hitachi SH-3 series RISC processor SH7709 is used as the example.
The main ISP1160 signals to be taken into consideration for connecting to a SH7709
RISC processor are:
A 16-bit data bus: D15 to D0 for the ISP1160. The ISP1160 is ‘little endian’
compatible.
The address line A0 is needed for a complete addressing of the ISP1160 internal
registers:
– A0 = 0 will select the Data Port of the Host Controller
– A0 = 1 will select the Command Port of the Host Controller
For MOSFET, RDSon = 150 m.
