STEVAL-IFP031V1 STMicroelectronics

STEVAL-IFP031V1 Data brief High speed digital input current limiter evaluation board based on CLT01-38SQ7 Features 8 inputs - 8-bit SPI output High side input with common ground 5 V voltage regulator Package: QFN 7 x 7 - 48 L 30 V reverse polarity capable Adjustable current limiters LED output for visual status Optional 16-bit mode with parity check, temperature and voltage alarms Daisy chain capable Power dissipation 78 mW per channel RoHS compliant 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 CLT01-38SQ7 device, which enhances I/O module density by reducing dissipation (78 mW per input) and 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. Product summary The STEVAL-IFP031V1 evaluation board can be connected in daisy chain with other STEVAL-IFP031V1 evaluation boards. High speed digital input STEVAL- current limiter IFP031V1 The adapter board can be placed between the first STEVAL-IFP031V1 evaluation evaluation board based board in the chain and the STEVAL-PCC009V2 STM32x microcontroller evaluation on CLT01-38SQ7 board. This adapter offers two buses: isolated and non-isolated.
