STEVAL-IFP030V1 STMicroelectronics

S T E VA L - I F P 0 3 0 V 1 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. The STEVAL-IFP030V1 evaluation board Features illustrates the flexibility of the SCTL3-8BQ7 with: 8/16-bit mode with parity check, temperature and 8 inputs - 8-bit SPI output voltage alarms daisy-chain capability adjustable High side input with common ground digital minimal filter time (20 s /160 s). 5 V voltage regulator Package: QFN 7 x 7 - 48L The STEVAL-IFP030V1 evaluation board can be 30 V reverse polarity capable chained with many other STEVAL-IFP030V1 Adjustable current limiters evaluation boards. LED output for visual status The adapter board can be placed between the Optional 16-bit mode with parity check, first STEVAL-IFP030V1 evaluation board of the temperature and voltage alarms chain and the STEVAL-PCC009V2 STM32x Daisy chain capable microcontroller evaluation board. This adapter Input digital filter with adjustable 20 to 160 provides 2 buses: isolated and non-isolated. s delay Power dissipation 78 mW per channel RoHS compliant December 2015 DocID028760 Rev 1 1/5 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-IFP030V1 1 Schematic diagram Figure 1: SCLT3-8BQ7 circuit schematic JP7 JP6 JP5 JP4 JP3 JP2 JP1 JP0 GSPG1412151150SG 2/5 DocID028760 Rev 1 Vcc Vcc R0 2.2K IN0 C0 R1 2.2K IN1 C1 J2 IN2 R2 2.2K C2 CN1 5 Connectable for 1 R3 2.2K IN3 C3 MOSI GND 4 2 Daisy Chain SCK INPUT0 3 3 R4 2.2K IN4 C4 /CS INPUT1 2 (Top Side) 4 INPUT2 1 5 IN5 R5 2.2K C5 INPUT3 GND BG302-05-A-L-G 6 INPUT4 7 IN6 R6 2.2K C6 INPUT5 8 INPUT6 VDD 9 R7 2.2K IN7 C7 INPUT7 1 0 J1 Vcc GND Vcc VCS 5 Connectable to MPT 0.5/10-2.54 MISO 4 Adapter board (Left Side) SCK 3 R8 /CS 2 (Right Side) VDD VDD 1 1.5M GND BG303-05-A-0300-L-G R9 64 Steps 8 bits 120K JMP1 JMP2 DVR SPM 8 Steps 16 bits 1K2 1K2 GND Vcc GND GND GND J3 Active Vcc 5 VCS VDD JMP3 MOSI Connectable for MISO 4 Daisy Chain Off SCK 1K2 3 U1 SCLT3-8BQ7 /CS 2 GND (Bottom Side) 2 1 DVR DVR VDD 1 3 4 8 OSC /CS /CS BG303-05-A-0300-L-G 4 4 7 R10 SPM SPM SCK SCK GND VCU1 1 3 4 6 VC MOSI 1 4 4 5 1.0K VCS /MISO 1 6 4 4 IN0 IN1 MISO MISO R11 1 7 4 2 IN1 IN2 REF C8 1 8 4 1 R12 IN2 IN3 LD1 15K 9 1 4 0 33nF IN3 IN4 LD2 51K 2 1 3 9 IN4 IN5 LD3 2 2 3 8 LED0 Green IN5 IN6 LD4 Miscellaneous GND GND 2 3 3 7 IN6 IN7 LD5 LED1 Green 2 4 3 6 F1 F3 IN7 IN8 LD6 7 3 5 SCR1 SCR3 LED2 Green COMP LD7 1 5 3 4 COMP LD8 LED3 Green 2 0 4 3 COMP COMS 3 1 3 3 LED4 Green COMP NC 5 3 2 SCR2 SCR4 F2 F4 NC NC LED5 Green 6 3 0 NC NC 8 2 9 LED6 Green NC NC 9 2 8 NC NC LED7 Green Mechanical Fiducial 1 0 2 7 NC NC 1 1 2 6 NC NC 1 2 2 5 NC NC TAB STEVAL-IFP030V1 4 9 GND GND GND GND
