Specifications of MAX191EVKIT-DIP

• Interface Type: Parallel, QSPI, Serial (SPI, Microwire)

The MAX191 EV system includes a Maxim 80C32 µC
module and a MAX191 EV kit. The two connect through a
40-pin data connector on adjoining edges of the boards.
The EV system then connects to an IBM-compatible com-
puter running software provided with the MAX191 EV kit.
The following steps outline the procedure for using the
MAX191 EV system:
1) Copy the MAX191 software disk to another disk or
2) Read the README text file found on the floppy disk.
3) Connect the MAX191 evaluation board to the 40-pin
