Description
This evaluation board implements an 8-line
protected digital input termination with serialized
state transfer for Programmable Logic
Controllers. It is based on the CLT01-8SQ7
device, which enhances the I/O module density
by cutting dissipation (78 mW per input) and
reducing the number of opto-transistors. A LED
driver is embedded in each input section.
Its 6.25 MHz SPI peripheral output serializes the
input state transfer to the I/O module controller.
The STEVAL-IFP030V1 evaluation board
illustrates the SCTL3-8BQ7 flexibility with: 8/16-
bit mode with parity check, temperature and
voltage alarms; daisy chain capability; MISO-
MISO/.
The STEVAL-IFP031V1 evaluation board can be
chained with many other STEVAL-IFP031V1
evaluation boards.
The adapter board can be placed between the
first STEVAL-IFP031V1 evaluation board of the
chain and the STEVAL-PCC009V2 STM32x
microcontroller evaluation board. This adapter
offers 2 buses: isolated and non-isolated.
