4. Expansion I/O (M66500FP)
A. Outline
The expansion I/O converts data from the CPU into load control
signals and input signals from sensors and switches into data for the
CPU.
The expansion I/O uses the M66500FP.
B. Features
•
I/Os are expandable up to 44 bits
(8-bit I/O port × 3, 8-bit high-dielectric output port × 2, 4-bit input
port × 1)
•
Directly connectable to 12 MHz CPU without weight
•
Writable to output port in input mode
•
Output terminal status can be read from CPU
•
Possible to drive transistor array
•
24 mA high-dielectric output port (16 bits) is incorporated.
•
TTL level terminal at CPU side
•
I/O terminal is CMOS level schmitt trigger input
