8 Application Information
The benefits of AS5163 are as follows:
8.1 Programming the AS5163
The AS5163 programming is a one-time-programming (OTP) method, based on polysilicon fuses. The advantage of this method is that no
additional programming voltage is needed. The internal LDO provides the current for programming.
The OTP consists of 128 bits, wherein several bits are available for user programming. In addition, factory settings are stored in the OTP
memory. Both regions are independently lockable by built-in lock bits.
A single OTP cell can be programmed only once. By default, each cell is “0”; a programmed cell will contain a “1”. While it is not possible to reset
a programmed bit from “1” to “0”, multiple OTP writes are possible, as long as only unprogrammed “0”-bits are programmed to “1”.
Independent of the OTP programming, it is possible to overwrite the OTP register temporarily with an OTP write command. This is possible only
if the user lock bit is not programmed.
Due to the programming over the output pin, the device will initially start in the communication mode. In this mode, the digital angle value can be
read with a specific protocol format. It is a bidirectional communication possible. Parameters can be written into the device. A programming of the
device is triggered by a specific command. With another command (pass2funcion), the device can be switched into operation mode (analog or
PWM output). In case of a programmed user lock bit, the AS5163 automatically starts up in the functional operation mode. No communication of
the specific protocol is possible after this.
8.1.1 Hardware Setup
The pin OUT and the supply connection are required for OTP memory access. Without the programmed Mem_Lock_USER OTP bit, the device
will start up in the communication mode and will remain into an IDLE operation mode. The pull up resistor R
startup.
