General Description
The SZ007A is an integrated Z‐Axis angular
rate sensor (Gyroscope). A single CLCC
package contains a high performance silicon
micro machined sensor with signal
conditioning circuitry.
It provides excellent temperature stability and
high resolution over the operating
temperature range (‐40℃ ~ 85℃)
It provides on‐chip temperature sensor, which outputs a voltage proportional to the temperature.
It has ±75 º/s , ±150 º/s and ±300 º/s full scale
selectable, and the signals of different full
scale can be accessed by using different I2C
commands conveniently. SZ007A is capable of
detecting rates with ‐3dB bandwidth up to
75Hz.
The SZ007A delivers output signal
proportional to angular rate perpendicular to
the assembly surface. SZ007A includes
low‐pass filters and EEPROM for on‐chip
factory calibration for the sensor. Factory
trimmed scale factors eliminates the need for
external active components and end‐user
calibration.
The SZ007A is provided in Ceramic package
(CLCC32) and the size is 10.668 mm x 10.668
mm x 2.9mm

Description of the bits mentioned in ADC section:
ADEN
ADC enable bit:
ADEN=0:ADC at a sleep mode and refused to be read;
ADEN=1:ADC work normally
Note: This bit should be set by Command ADCC, and cleared after power up
BUSY This bit will be set after chip reset and will be cleared after initialization inside chip
If busy = 1 ,then chip send Refuse signal only
CHAN
CHAN bit is used to select input Source of ADC
CHAN = 0: input Angular rate channel
CHAN = 1: Temperature will be converted
Note: This bit Can be Set by Command ADCC and cleared after power up
EOC End of AD-conversion bit. EOC bit indicates an ADC state.
EOC=0 : ADC in progress and can not be restarted.
EOC=1 : AD-conversion has been completed and can be restarted.
As a result, any attempt of the ADC starting will be rejected if EOC has a “0” state.
OPC Unknown Operation Code. This bit is set when a received operation code was not
recognized.
X These bits are reserved or have an undefined state.
6.3.1 ADC Instructions and Answers
There are three SPI commands that are used to control embedded ADC of the SZ007A: STATR,
ADCC and ADCR.
The Refusal Answer
Every instruction sent to the SZ007A has an answer. If the SZ007A is not able to accept the
instruction a refusal answer will be transmitted out. This answer has a unique format which is
shown in the Table 7. The refusal answer is the only one that has a set MSB. The other bits help
to understand a possible reason for the instruction rejection.

6.3.2 Reading the Digital Angular Rate or Temperature (suggested procedure)
There is a recommended sequence below to obtain digital data from the ADC.
Notes:
‐ The bit with leftmost position should be shifted first.
‐ Below “x” means any value: “0” or “1”.
Step 1 (put ADC to the active mode if it wasn’t)
Use SPI to send ADCC instruction (MOSI):
And check 15th bit of the answer (MISO):
If 15th bit is zero, the instruction is accepted.
Before to go to the Step 2 provide a delay > 115 μs or wait till the EOC bit is set.
Step 2 (conversion start)
Use SPI to send ADCC instruction(MOSI):
And check 15th bit of the answer (MISO):
If 15th bit is zero, the instruction is accepted.
CHAN bit specifies the input source of the ADC.
CHAN=0: The angular rate signal.
CHAN=1: The temperature sensor signal.
SZ007A Preliminary Specification
SENODIA Technologies(SH) Co., Ltd. Page 10 of 17 Rev 0.2 www.senodia.com
Go to the Step 3.
• Step 3 (polling and result obtaining)
Use SPI to send ADCR instruction and check 15th and 13th bits of the answer:
If 15th bit is zero, the instruction is accepted.
If 13th bit (EOC) is zero, the conversion is still in progress and the result of the
conversion (bits AD10…AD0) is not valid. As soon as the EOC bit is set the conversion is
completed and the result is valid.
Instead of the polling of the EOC bit one can use a simple delay that should be bigger
than a maximal conversion time (>115 μs, see table 4).
Go to the Step 2 to do the next conversion or to the Step 4 to put ADC to the sleep mode.
Step 4 (put ADC to the sleep mode if it’s necessary)
Use SPI to send ADCC instruction (MOSI):
And check 15th bit of the answer (MISO):
If 15th bit is zero, the instruction is accepted.
7. Applications Examples
Figure 7.1 SZ007A with simultaneous analog and digital output
The SZ007A can simultaneously output analog and digital signals. The analog output signal can be
fed to a microcontroller (μC) that contains an analog‐to‐digital converter. A multiplexer can be
used to select between the temperature and the angular rate signals. The SZ007A generates an
internal reference voltage used for supplying the ADC, thereby maintaining accuracy regardless of
the supply voltage of the μC. Whilst supplying the analog output signal, the SZ007A can
simultaneously send a digital output signal to the μC through the SPI.

1. The bandwidth of the SZ007A can be selected by connecting an appropriate capacitor inthe
FLT pin. CFLT implements a first order low pass filter cascaded with an internal 4‐th order SC
filter. The –3dB bandwidth set by CFLT is: fOUT =0.16 / (ROUT*CFLT), with ROUT = 200k_
(typ). It is recommended to use CFLT even if the cut‐off frequency is not specified to reduce
switching spikes at the output.
2. It is recommended to use X5R or X7R type capacitors. Min. voltage for C3 should be 25V or
more, and 10V or more for the other capacitors. Recommended values of decoupling
capacitors C1 and C2 are 1.0μF and 0.1μF for C3. These capacitors should be placed as close
as possible to their respective pins.
3. HVIN is a high impedance node. Be sure that an equivalent leakage resistance at this node

SPI pins. All other pins continue to be used as described above.
