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.
