(USB I&P Box) P1 has to be populated with a 2x8 pin header and is required for power supply as well as SPI, ABI, UVW/PWM interfaces. The connector JP1 allows to select between 5V or 3.3V operation. R1 and R2 are 0 ohm resistors in 0603 package. Depending on the supply voltage either R1 or R2 has to be populated. For 5V operation R1 has to be populated and R2 has to be removed (default case). Vice versa for 3.3V operation.

The airgap between the magnet surface and the package should be maintained in the range 0.5mm to 3mm. The magnet holder must not be ferromagnetic. Materials as brass, copper, aluminum, stainless steel are the best choices to make this part. ams Eval Kit Manual, Confidential [v1-0] 2015-Jan-14 Page 5 Document Feedback AS5147P Adapter Board 3 AS5147P adapter board and pinout Figure 4: AS5147P adapter board and sensor pinout B 3V3 A NC I/PWM CSn TEST CLK NC MOSI W/PWM MISO V GND CSn 1 14 I/PWM CLK 2 13 GND MISO 3 12 VDD3V MOSI 4 11 VDD TEST 5 10 U B 6 9 V A 7 8 W/PWM U 5V/3V3 AS5147P AS5147P 5V Pin# Board Pin# AS5147P Symbol board Type P1 - 1 11 5V Power supply Positive supply voltage P1 - 2 12 3V3 Power supply 3.3V LDO output P1 - 3 NC Description Not connected P1 - 4 1 CSn Digital input SPI chip select (active low) P1 - 5 2 CLK Digital input SPI Clock P1 - 6 4 MOSI Digital input SPI MOSI P1 - 7 3 MISO Digital output SPI MISO P1 - 8 13 GND Power supply Ground P1 - 9 6 B Digital output Incremental signal B (quadrature) P1 - 10 7 A Digital output Incremental signal A (quadrature) P1 - 11 14 I/PWM Digital output Incremental signal I (index) or PWM P1 - 12 5 TEST P1 - 13 Test pin NC Not connected P1 - 14 8 W/PWM Digital output Commutation signal W or PWM P1 - 15 9 V Digital output Commutation signal V P1 - 16 10 U Digital output Commutation signal U ams Eval Kit Manual, Confidential [v1-0] 2015-Jan-14 Page 6 Document Feedback AS5147P Adapter Board 4 Operation case 4.1 One device SPI mode, unidirectional – 3 wire The AS5147P adapter board can be directly connected to an industry standard SPI port of a microcontroller. The minimum connection requirements for unidirectional communication between the microcontroller and the AS5147P are MISO, CLK, CSn. In this case the MOSI pin is tied to VDD which will result in reading only the 14-bit Angle Register (0x3FFF). See AS5147P datasheet register table, register 0x3FFF.
