STEVAL-IFP030V1

STEVAL-IFP030V1 High speed digital input current limiter evaluation board based on SCLT3-8BQ7 Data brief 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 SCLT3-8BQ7 device. The SCLT3-8BQ7 enhances the I/O module density by cutting the dissipation (78 mW per input) and reducing the opto-transistor count. An adjustable digital filter and an LED driver are embedded in each input section. Its 2 MHz SPI peripheral output serializes the input state transfer to the I/O module controller. Features             8 inputs - 8-bit SPI output High side input with common ground 5 V voltage regulator Package: QFN 7 x 7 - 48L 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 Input digital filter with adjustable 20 to 160 µs delay Power dissipation 78 mW per channel RoHS compliant December 2015 The STEVAL-IFP030V1 evaluation board illustrates the flexibility of the SCTL3-8BQ7 with: 8/16-bit mode with parity check, temperature and voltage alarms; daisy-chain capability; adjustable digital minimal filter time (20 µs /160 µs). The STEVAL-IFP030V1 evaluation board can be chained with many other STEVAL-IFP030V1 evaluation boards. The adapter board can be placed between the first STEVAL-IFP030V1 evaluation board of the chain and the STEVAL-PCC009V2 STM32x microcontroller evaluation board. This adapter provides 2 buses: isolated and non-isolated.
