1. Product profile
1.1 General description
The KMA200 is an angle sensor system. The MagnetoResistive (MR) element and the
mixed signal Integrated Circuit (IC) are integrated in one package. This angle system is
already pre-programmed, offsets are compensated and therefore, ready to use.
Via the Serial Peripheral Interface (SPI) the KMA200 is user programmable. This allows
user specific adjustments of the maximum angle, zero point, clamping level and a 32-bit
identifier. The data is stored permanently in an Electrically Erasable Programmable
Read-Only Memory (EEPROM).
The device can be programmed to work either in analog or digital (SPI) output mode.
Furthermore, different analog output characteristics are possible. The resolution is better
than 0.05.
The implemented online diagnosis supervises the input and output signals as well as the
data processing. Deviations and failures of the angle value are indicated in the output
signal. Overall temperature supervision is implemented.

5. Functional description
The KMA200 amplifies two orthogonal sinusoidal signals delivered by the MR-sensor
element and converts them into the digital domain. Using the COordinate Rotation DIgital
Computer (CORDIC) algorithm, the angle is calculated. Angle output is either analog or
digital. The KMA200 comprises diagnostic features that ensure a complete online
supervision of all essential functional blocks including verification of input and output
signals and temperature supervision. In addition, the circuit is protected against reverse
polarity, overvoltage and short circuit at all external pins.
Two instrumentation amplifiers and -modulators convert the amplified signals into two
high-speed digital bit streams. The bit streams are filtered and decimated by two digital
decimation filters to obtain digital signals with higher resolution at a lower speed.
Further processing is done within an on-chip calibration microcontroller. This includes
offset cancellation, calculation of the mechanical angle using the CORDIC algorithm,
zero-angle and angular-range adjustment.
In addition, the calibration microcontroller performs diagnostic tasks to ensure the validity
of its results. The calibration microcontroller takes calibration constants from an on-chip
EEPROM and stores intermediate results in a Random Access Memory (RAM). The
calculated angle is given out either digitally with an SPI-compatible serial interface or
analog via the analog output stage. Several output characteristics can be selected.
In case of analog output the analog output stage is used for conversion of the angle
information into two analog output voltages ratiometric to the supply voltages. For this
purpose, the analog output stage contains two resistor-string Digital-to-Analog Converters
(DACs) which share the same resistor string. The two analog output voltages are buffered
by two offset-compensated amplifiers.
The internal circuitry is protected against overvoltage with special protection circuits.
Protection against reverse polarity is realized with the help of a current limiting circuit.
In addition, there are various support circuits like bias generators, a free-running oscillator
including an oscillator fail-safe circuit and a power-on reset circuit which generates a reset
in dependence of the supply voltage.

6. Diagnostic features
The KMA200 includes diagnostic features to ensure the validity of its output signals. The
diagnostic features can be configured with the control information words (ctrl) written to
the user-programmable EEPROM.
In the analog output modes a diagnostic error condition is signaled to the user by setting
the outputs into the high-impedance state. The outputs are forced to lie in the upper or
lower diagnostic range by external pull-up or pull-down resistors.
With no external pull-up/pull-down resistors the output signal will be internally pulled up to
upper diagnosis range.
If digital output is selected, an error condition can also be signaled by setting the error flag
in the digital output word. The least significant bits show the error code. The Table 4
shows the behavior in detail:
Once a diagnostic error condition is reached, the KMA200 continues to work normally
after a new external power-on reset or by itself, as described in the table below. It is
possible to configure the KMA200 the way that the error condition has to be fulfilled more
than once. The number of error conditions that is necessary can also be programmed with
bits in the control information words.

Temperature supervision
The chip temperature measured within the KMA200 can be used to detect
over-temperature conditions. Two temperature levels are defined: the temperature
warning level and the temperature shutdown level.
The user can evaluate the temperature warning if digital output mode is selected. When
the device temperature exceeds the warning level, the error flag in the digital output word
is set. The other data bits still show the angle information. In the analog output modes, the
device temperature warning is not available. If the temperature exceeds the
over-temperature shutdown level, the KMA200 switches off.

Diagnosis of input stage
For diagnosis of the input stage, the calibration microcontroller calculates the expected
signal magnitude using the temperature information and the EEPROM constants and
compares it to the signal magnitude based on the current measurement.
If the difference of the two magnitudes is greater than an allowed deviation, an error
condition is signaled to the user.
The allowed difference depends on the bits DI1 and DI0 in the EEPROM control
information word.
Diagnosis of output stage
Both analog outputs are supervised by the auxiliary ADC which reads the present analog
signal and converts it back to the digital domain with a resolution of 8 bits. The digitized
value is compared to the digital angle value originally sent.
If the difference of these two values is greater than an error bound, an error condition is
signaled by switching off the analog outputs.
The allowed difference depends on the bits DO1 and DO0 in the EEPROM control
information word.
CRC check of EEPROM constants
During normal operation mode a CRC code of the configuration constants taken from the
EEPROM is calculated on a regular basis. This code is compared to a pre-calculated CRC
code from the EEPROM (CRC). If there is a mismatch, an error condition is signaled to
the user by setting the error flag in the digital output word or by switching off the analog
outputs.
The CRC code used is the CRC-16 code (ISO/IEC 3309:1993 and ITU-T V.42)
Watchdog timer
The KMA200 comprises a watchdog timer to supervise the flow of the program. After
reset, the watchdog is automatically activated. During operation the watchdog timer must
be toggled on a regular basis, as otherwise the error condition is signaled. The access to
the watchdog timer is protected against unwanted operations using a fail-safe watchdog
feed sequence.

7. Outputs of KMA200
The output of the KMA200 is either digital or analog, depending on the control word stored
in the EEPROM. The analog output consists of a standard and a programmable output
stage. The programmable output stage allows four different characteristics; mode 1,
mode 2, mode 3 or none output. The digital output has two different modes; mode 5 and
mode 6.
Analog output
In the analog output mode the measured angle value is converted linear into a value that
is ratiometric to the supply voltage VDD. This voltage is driven by the standard output
stage to pin DATA/OUT1. The same value is fed to a second output stage that is
connected to pin CLK/OUT2. This second output stage is programmable to one of four
different output characteristics; mode 1, mode 2, mode 3 or high-impedance state output.
A valid angle value is nominally mapped to an output voltage range of V(CL)l
(default = 5 %) to V(CL)u (default = 95 %) of VDD at the standard output VOUT1
(see Figure 3).
For mode 1 the valid output voltage range at pin CLK/OUT2 is identical to the output
voltage range of the standard analog voltage but the output characteristic is inverted
(see Figure 4).
In mode 2 (see Figure 5) the valid output range at pin CLK/OUT2 is nominally V(CL)l/2 to
V(CL)u/2 of VDD.
A further possibility is to program the VOUT2 (mode 3, thresh) as a comparator depending
from the angle value (see Figure 6).
When the KMA200 detects an error condition, it switches the analog outputs into
high-impedance state. The outputs are forced to lie in the upper or lower diagnostic range
by the external pull-up or pull-down resistors.

8. Digital output (SPI)
Standard digital output
If the standard digital output mode is configured, output data can be read with the serial
interface. Figure 7 shows the timing diagram of an interface access. The access is
enclosed by a HIGH-to-LOW and LOW-to-HIGH transition of CS.
DATA are clocked out at the falling edge of CLK and should be evaluated at the rising
edge. The output data consist of 3 bytes (24 bits). The first two data bytes contain an error
flag and 13 bits of angle information. The last data byte contains the measured
temperature as 7-bit value. Every byte features a parity bit (odd parity).
The data transmission can be interrupted at any time by deactivating CS. If, for instance,
the temperature information is not desired, the data transfer can be finished by
deactivating CS after reading the first two data bytes.
If the error flag is 0, the 13 angle data bits contain the most significant bits of the
calculated angle. If the error flag is 1, an error condition was detected. The two least
significant angle data bits (A[1:0]) are replaced by an error code. All other angle data bits
(A[12:2]) still show the current measurement value. Depending on the special error case,
the measurement values are reliable or not. Error codes are described in Table 8.
The output driver of the DATA pin is slew-rate limited. The rise and fall times of the DATA
output can be programmed with the SL bit (ctrl EEPROM constant); see Table 12.
Complementary digital output
In complementary digital output mode the data transmitted is identical to the output data in
standard digital output mode except that the angle and temperature information data bits
are logically inverted. The error flag and the error code in bits A[1:0] when the error flag is
set are coded as in case of standard digital output. The parity bits also use odd parity as
standard digital output mode.

12. Definition of errors
12.1 General
For the accuracy is assumed that the sensor operates in a homogeneous magnetic field at
saturation field strength Hsat. Also, the zero angle register of the KMA200 is set at a
mechanical reference point at room temperature (and zero degree).

180
ϕ ref (°)
ref: reference angle in degree
meas: measured angle of the KMA200 in degree
lin: deviation from reference line in degree
Fig 8.
Visualization of linearity behavior
This reference line is valid for digital and analog outputs. The maximum angle is set to
180 and the clamping levels are programmed to V(CL)l = 5 %VDD and V(CL)u = 95 %VDD.
12.2 Linearity error
The deviation from the reference line lin is called angle linearity error and defined as
follows:
lin = lin(ref,Tj)  ref
Tj: any ambient temperature in the specific range
Following formula is used to calculate meas in degree from an analog voltage value:
V OUT – 5 %V DD
 meas = --------------------------------------------------  180
95 %V DD – 5 %V DD
(3)
VOUT: analog output of KMA200 [%VDD]
For sensors the error of the analog output lin is only defined in the range from 5.5 %VDD
to 94.5 %VDD.

12.4 Microlinearity
Microlinearity is the deviation between the device output and the reference line at any
angle and for an angle step of 1. The microlinearity is determined at a constant
temperature.

Fig 10. Microlinearity behavior
The microlinearity is calculated as follows:
lin = Vmeas(ref(i+1))  Videal(ref(i+1))
Videal(ref(i+1)) = Vmeas(ref(i)) + mideal  1 = Vmeas(ref(i)) + 0.5 %VDD
lin: microlinearity
Vmeas(ref(i)): measured voltage [%VDD] for angle position ref(i)
mideal: ideal, theoretical slope; with 90 %VDD and maximum angle 180
The output slopes are monotonic by design. This figures can also be used for the
definition of lin in digital mode, as follows: assume that
Vmeas(ref(i)) = meas(ref(i)) and Vmeas(ref(i+1)) = meas(ref(i+1)),
whereas meas(X) is the output angle of the KMA200 at the angle position X.

12.5 Hysteresis
The hysteresis error is defined as the maximum difference between angle values given by
the device output when performing a positive (clockwise) rotation and negative rotation
(counter clockwise) over an angle range of 180.

hys: hysteresis
meas: CW measured angle for clockwise rotation
meas: CCW measured angle for counter clockwise rotation
13. Programming
The KMA200 comprises two major modes of operation. These modes are:
13.1 Normal operation mode
This is the default mode. The KMA200 starts in this mode without the need of writing to
the serial interface. In this mode a continuous conversion of the input signals into the
corresponding angles takes place. This mode is configured with the on-chip EEPROM.
Once in normal operation mode, the KMA200 can be reactivated for command mode only
by a new power-on reset.

13.2 Command mode
This mode is used for calibration and programming. The KMA200 is controlled with serial
interface commands.
To activate the command mode, the following initialization procedure must be executed
during power-on reset. The pin CS must be constantly held on HIGH level and
pin CLK/OUT2 must be constantly held on LOW level during power-on. This condition has
to start during reset and must be valid during the following initialization phase of the
KMA200 for at least 1 ms. CS and CLK are internally weak pull-up so that at least CLK
must be actively driven. If these conditions are valid, the KMA200 starts in command
mode. At all other combinations or if the levels are not constant for the minimum time of
1 ms, the KMA200 starts in normal operation mode.

Fig 12. Command mode
The normal operation mode is configured with sixteen 16-bit constants stored in the
on-chip EEPROM.
13.3 Notes to the programming
The KMA200 sensor is delivered in a pre-calibrated and preprogrammed default
condition.
The EEPROM addresses 0, 1, 5, C, D and E are device dependent and pre-calibrated
for each device. A changing of this contents to another value is not allowed,
because the specified data, influenced by these addresses, are no longer valid.
The EEPROM addresses A and B are used to store production related information.
A changing of these values should not be done.
Definition:
Address A: storage the date code. Date code assembly center: day of the year
(maximum 365) + year (maximum 99)

13.4 Write RAM (0nh), read RAM (1nh)
To write data to the RAM the command byte 0nh (n is the address of the data) followed by
the 16-bit data has to be send. To read data from the RAM, the command byte 1nh has to
be send. If CS is activated again, the RAM contents at the specified address is clocked
out. Note that at power-on addresses 00h to 0Fh are read from the EEPROM into the
RAM.
13.5 Calculate CRC-16 and program EEPROM (30h)
To program the EEPROM, the configuration data has to be written to the RAM addresses
00h to 0Eh. Afterwards, the command byte 30h has to be sent and the EEPROM
programming voltage has to be applied at the VDD pin. The KMA200 calculates the
CRC-16 check sum and writes the RAM constants at addresses 00h to 0Fh to the
EEPROM. This command is only executed when the EP bit in the control information word
is logic 0 on power-on. If the EP bit is logic 1, this command is ignored.
