angular measurement over a full turn of 360º and over an extended
ambient temperature range of -40ºC to +150ºC.
High precision analog output
SSI Interface
Low power mode
Two programmable output modes: Differential or Single ended
Wide magnetic field input range: 20 – 80 mT

An SSI Interface is implemented for signal path configuration as well
as a one time programmable register block (OTP), which allows the
customer to adjust the signal path gain to adjust for different
mechanical constraints and magnetic field.
Buffered Sine and Cosine signals
lv
Based on an integrated Hall element array, the angular position of a
simple two-pole magnet is translated into analog output voltages.
The angle information is provided by means of buffered sine and
cosine voltages. This approach gives maximum flexibility in system
design, as it can be directly integrated into existing architectures and
optimized for various applications in terms of speed and accuracy.

7 Detailed Description
The benefits of AS5115 are as follows:
Complete system-on-chip, no angle calibration required
Ideal for applications in harsh environments due to magnetic sensing principle
High reliability due to non-contact sensing
al
id
Robust system, tolerant to horizontal misalignment, temperature variations and external magnetic fields
7.1 Sleep Mode
lv
The target is to provide the possibility to reduce the total current consumption. No output signal will be provided when the IC is in sleep mode.
Enabling or disabling sleep mode is done by sending the SLEEP or WAKEUP commands via. the SSI interface. Analog blocks are powered
down with respect to fast wake up time.
7.2 SSI Interface

st
il
The setup for the device is handled by the digital interface. Each communication starts with the rising edge of the chip select signal. The
synchronization between the internal free running analog clock oscillator and the external used digital clock source for the digital interface is
done in a way that the digital clock frequency can vary in a wide range.

7.7 One Time Programming Content
The AS5115 die has an integrated 46-bit OTP ROM (Easyzapp) for trimming and configuration purposes. The PROM can be programmed via.
the serial interface. For irreversible programming, an external programming voltage at PROG pin is needed. For security reasons, the factory
trim bits can be locked by a lock bit.
ca
As shown in the table below, the OTP holds 46 bits. Bit number 44 and 45 are used for OTP testing purposes and ESD protection of the
remaining cells.

The AS5115 provides analog Sine and Cosine outputs (SINP, COSP) of the Hall array front-end for test purposes. 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 must be kept as
short as possible. In the case of longer lines, they must be shielded in order to achieve best noise performance.
Te
ch
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.

Remove for normal operation
ch
Note: The maximum capacitive load at PROG in normal operation should be less than 20pF. However, during programming the capacitors
C1+C2 are needed to buffer the programming voltage during current spikes, but they must be removed for normal operation. To
overcome this contradiction, the recommendation is to add a diode (4148 or similar) between PROG and VDD as shown in Figure 9
(special case setup), if the capacitors can not be removed at final assembly.
Te
Due to D1, the capacitors C1+C2 are loaded with VDD - 0.7V at startup, hence not influencing the readout of the internal OTP registers.
During programming the OTP, the diode ensures that no current is flowing from PROG (8V - 8.5V) to VDD (5V).
In the standard case (see Figure 9), the verification of a correct OTP readout can be done by analog readback of the OTP register.
As long as the PROG pin is accessible it is recommended to use standard setup. In case the PROG pin is not accessible at final
assembly, the special setup is recommended.

For programming of the OTP, an additional voltage has to be applied to the pin PROG. It has to be buffered by a fast 100nF capacitor (ceramic)
and a 10µF capacitor. The information to be programmed is set by command 25. The OTP bits 16 until 45 are used for AMS factory trimming and
cannot be overwritten.

After programming, the programmed OTP bits can be verified in two ways:
lv
By Digital Verification: This is simply done by sending a READ OTP command (#15). The structure of this register is the same as for the OTP
PROG or OTP WRITE commands.
am
lc s
on A
te G
nt
st
il
By Analog Verification: By switching into Extended Mode and sending an ANALOG OTP READ command (#9), pin PROG becomes an output,
sending an analog voltage with each clock representing a sequence of the bits in the OTP register (starting with D45). A voltage of <500mV
indicates a correctly programmed bit (“1”) while a voltage level between 2V and 3.5V indicates a correctly unprogrammed bit (“0”). Any voltage
level in between indicates incorrect programming.
