ANGLE 4 CLICK AEAT-8800-Q24

[mco]

Hi Friends,

Angle 4 click have AEAT-8800-Q24 magnetic encoder.
My first question; I need 16bit resolution and absolute output mode. Angle 4 click's page says "The absolute angular position can be read from the SPI interface." and "in order to provide absolute angular position over the industry standard SPI interface"

But aeat-8800-q24 datasheet says "Three-wire SSI interface for absolute output" (Key Features part) and "When selected, its positioning data is then represented in its digital form to be assessed through a standard SSI 3 wire communication protocol."
and "The AEAT-8800-Q24 provides SSI 3 wires and PWM outputs to indicate absolute position of the motor."

For 16 bit-absolute output, I understand that SSI must be used for absolute output in the datasheet of the encoder. How to send 16 bit data over SPI interface?
At datasheet
"To read an address using SPI:
DIN: Read<2'b10>Address<5:0>; from 8 bits DIN
Read 8-bit data on DO by clocking 8 SPI_CLK clock.(Page 20)" Only 8 bits but i need 16bit resolution.



My second question;
Encoder recommended voltage value is 5.6V for OTP programming. My microcontroller operate with 3.3V then i don't know what will be the voltage of 10( SSI_SCL_SPI_CLK), 11(SSI_NSL_SPI_DI) , 12(SSI_DO_SPI_DO),21(SSI_SPI_SEL) at OTP mode. This mode can damage my processor, Do you have any idea about voltage of these pins at OTP mode ? They will be 5.6V all pins or different.


My third question;
Encoder datasheet says "An internal voltage regulator allows the AEAT-8800-Q24 to operate at either 3.3V or 5V supplies.(Page 1)"
What does it means. For give an example I give 3.3V VDDA pins. It converts lower than 3.3v then output pins give boost 3.3v ?


My last question;
Angle 4 click page says "However, the OTP memory will not be permanently written, unless appropriate programming voltage is applied to the VDDP pin." VDDP pins are #14 and #19 or different things ?

Thank you for concern.

Amazing.

Can the rest of us get in on this information?

Hi,

These questions are very specific to the sensor itself, therefore it was suggested that the customer contact Broadcom as they are the sensor manufacturer.
