The connector JP2 provides acces to PROG, CM_SIN1 and CM_SIN2. Resistors R1, R2 (100k) are used as Pull-up on CS pin and capacitors C1, C2 (2.2uF) are placed between VDD and GND.

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 [v1-1] 2014-Nov-18 Page 5 Document Feedback AS5215 Adapter Board 3 AS5215 adapter board and pinout PROG CM_2 AS5215 NC NC DCLK_1 VDD_2 DCLK_2 VDD_1 CS_1 26 25 24 NC DIO_2 2 23 NC TC_1 3 22 NC 21 NC 20 NC 6 19 NC 7 18 COSN_2/COSP_2/CM_COS_2 17 COSP_2/COSN_2 TC_2 4 A_TST_1 5 A_TST_2 PROG_1 PROG_2 8 AS5215 9 10 11 12 13 14 15 COSP_1/COSN_1 COS 27 SINN_2/SINP_2/CM_SIN_2 SIN 28 SINP_2/SINN_2 DIO 29 SINP_1/SINN_1 CS 30 SINN_1/SINP_1/CM_SIN_1 CLK 31 1 VSS_2 5V 32 DIO_1 VSS_1 GND CS_2 Figure 4: AS5215 adapter board and sensor pinout 16 COSN_1/COSP_1/CM_COS_1 CM_1 Pin# Board Pin# AS5215 Symbol board Type P1 - 1 9, 10 GND Power supply Ground (Die 1) P1 - 2 9, 10 GND Power supply Ground (Die 2) P1 - 3 27, 28 5V Power supply Positive supply voltage (Die 1) P1 - 4 27, 28 5V Power supply Positive supply voltage (Die 2) P1 - 5 29 CLK Digital input Clock for digital interface (Die 1) P1 - 6 30 CLK Digital input Clock for digital interface (Die 2) P1 - 7 31 CS Digital input Chip select for digital interface (Die 1) P2 - 8 32 CS Digital input Chip select for digital interface (Die 2) P2 - 9 1 DIO Digital input Data I/O for digital interface (Die 1) P2 - 10 2 DIO Digital input Data I/O for digital interface (Die 2) P2 - 11 11 SIN Analog output Switchable buffered analog outputs (Die 1) P2 - 12 13 SIN Analog output Switchable buffered analog outputs (Die 2) P2 - 13 15 COS Analog output Switchable buffered analog outputs (Die 1) P2 - 14 17 COS Analog output Switchable buffered analog outputs (Die 2) JP2 - 1 7, 8 PROG Power supply OTP programming pad JP2 - 2 14 CM_2 Analog output Switchable buffered analog outputs (Die 1) JP2 - 3 12 CM_1 Analog output Switchable buffered analog outputs (Die 2) ams Eval Kit Manual, Confidential [v1-1] 2014-Nov-18 Description Page 6 Document Feedback AS5215 Adapter Board 4 Operation case 4.1 Standalone sine-cosine output The AS5215 provides analog Sine and Cosine outputs (P1 – 11, P1 – 13 and P1 – 12, P1 - 14). These outputs allow the user to perform the angle calculation by an external ADC + μC, e.g. to compute the angle with a high resolution. The signal lines should be as short as possible, longer lines should be shielded in order to achieve best noise performance. Through the programming of one bit, you have the possibility to choose between the analog Sine and Cosine outputs (SINP, COSP) and their inverted signals (SINN, COSN). Furthermore, by programming the bits <9:10> you can enable the common mode output signals of SIN and COS (JP2 – 2 and JP – 3). The DC bias voltage is 1.5 or 2.5 V. For further information, please refer to datasheet.

It has to be buffered by a fast 100nF capacitor (ceramic) and a 10μF capacitor (as close as possible to PROG pin). Programming of the AS5215 OTP memory does not require a dedicated programming hardware. The programming can be simply accomplished over the serial 3-wire interface. For permanent programming (command PROG OTP, #25), a constant DC voltage of 8.0 – 8.5V (=100mA) must be connected to PROG. For temporary OTP write (“soft write”; command WRITE OTP, #31), the programming voltage is not required. For further information, please refer to datasheet.
