GENERAL DESCRIPTION
The ADIS16362 iSensor(R) is a complete inertial system that includes a triaxis gyroscope and triaxis accelerometer. Each sensor in the ADIS16362 combines industry-leading iMEMS(R) technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyro bias). As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements over a temperature range of -20C to +70C. The ADIS16362 provides a simple, cost-effective method for integrating accurate, multiaxis, inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs.

motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. An improved SPI interface and register structure provide faster data collection and configuration control. The ADIS16362 uses a compatible pinout and the same package as the ADIS1635x family. Therefore, systems that currently use the ADIS1635x family can upgrade their performance with minor firmware adjustments in their processor designs. This compact module is approximately 23 mm x 23 mm x 23 mm and provides a flexible connector interface that enables multiple mounting orientation options.

The digital I/O signals are driven by an internal 3.3 V supply, and the inputs are 5 V tolerant. Endurance is qualified as per JEDEC Standard 22, Method A117, and measured at -40C, +25C, +85C, and +125C. 3 The data retention lifetime equivalent is at a junction temperature (TJ) of 85C as per JEDEC Standard 22, Method A117. Data retention lifetime decreases with junction temperature. 4 These times do not include thermal settling and internal filter response times (330 Hz bandwidth), which may affect overall accuracy. 5 The sync input clock functions below the specified minimum value, at reduced performance levels.

ADIS16362 THEORY OF OPERATION
BASIC OPERATION
The ADIS16362 is an autonomous sensor system that starts up after it has a valid power supply voltage and begins producing inertial measurement data at the factory default sample rate setting of 819.2 SPS. After each sample cycle, the sensor data is loaded into the output registers, and DIO1 pulses high, which provides a new data ready control signal for driving systemlevel interrupt service routines. In a typical system, a master processor accesses the output data registers through the SPI interface, using the connection diagram shown in Figure 9. Table 6 provides a generic functional description for each pin on the master processor. Table 7 describes the typical master processor settings that are normally found in a configuration register and used for communicating with the ADIS16362.
VDD I/O LINES ARE COMPATIBLE WITH 3.3V OR 5V LOGIC LEVELS

The user registers provide addressing for all input/output operations on the SPI interface. Each 16-bit register has two 7-bit addresses: one for its upper byte and one for its lower byte. Table 8 lists the lower byte address for each register, and Figure 10 shows the generic bit assignments.

READING SENSOR DATA
Although the ADIS16362 produces data independently, it operates as a SPI slave device that communicates with system (master) processors using the 16-bit segments displayed in Figure 11. Individual register reads require two of these 16-bit sequences. The first 16-bit sequence provides the read command bit (R/W = 0) and the target register address (A6 to A0). The second sequence transmits the register contents (D15 to D0) on the DOUT line. For example, if DIN = 0x0A00, the contents of XACCL_OUT are shifted out on the DOUT line during the next 16-bit sequence. The SPI operates in full-duplex mode, which means that the master processor can read the output data from DOUT while using the same SCLK pulses to transmit the next target address on DIN.

DEVICE CONFIGURATION
The user register memory map (see Table 8) identifies configuration registers with either a W or R/W. Configuration commands also use the bit sequence shown in Figure 11. If the MSB = 1, the last eight bits (DC7 to DC0) in the DIN sequence are loaded into the memory address associated with the address bits (A6 to A0). For example, if DIN = 0xA11F, 0x1F is loaded into Address 0x21 (XACCL_OFF, upper byte) at the conclusion of the data frame. The master processor initiates the backup function by setting GLOB_CMD[3] = 1 (DIN = 0xBE04). This command copies the user registers into their assigned flash memory locations and requires the power supply to stay within its normal operating range for the entire 50 ms process. The FLASH_CNT register provides a running count of these events for monitoring the long-term reliability of the flash memory.

BURST READ DATA COLLECTION
Burst read data collection is a process-efficient method for collecting data from the ADIS16362. In burst read, all output registers are clocked out on DOUT, 16 bits at a time, in sequential data cycles (each separated by one SCLK period). To start a burst read sequence, set DIN = 0x3E00. The contents of each output register are then shifted out on DOUT, starting with SUPPLY_OUT and ending with AUX_ADC (see Figure 13). The addressing sequence shown in Table 8 determines the order of the outputs in burst read. Table 11. Rotation Rate, Twos Complement Format

CALIBRATION
Manual Bias Calibration
The bias offset registers in Table 15 and Table 16 provide a manual adjustment function for the output of each sensor. For example, if XGYRO_OFF = 0x1FF6 (DIN = 0x9B1F, 0x9AF6), the XGYRO_OUT offset shifts by -10 LSBs, or -0.125/sec. Table 15. XGYRO_OFF, YGYRO_OFF, ZGYRO_OFF Bit Descriptions
Bit [15:13] [12:0] Description (Default = 0x0000) Not used. Data bits. Twos complement, 0.0125/sec per LSB. Typical adjustment range = 50/sec.
Restoring Factory Calibration
Set GLOB_CMD[1] = 1 (DIN = 0xBE02) to execute the factory calibration restore function. This function resets each user calibration register to 0x0000 (see Table 15 and Table 16), resets all sensor data to 0, and automatically updates the flash memory within 50 ms (see Table 17).
Linear Acceleration Bias Compensation (Gyroscope)
Set MSC_CTRL[7] = 1 (DIN = 0xB486) to enable correction for low frequency acceleration influences on gyroscope bias. Note that the DIN sequence also preserves the factory default condition for the data ready function (see Table 22).
OPERATIONAL CONTROL
Global Commands
The GLOB_CMD register provides trigger bits for several useful functions. Setting the assigned bit to 1 starts each operation, which returns the bit to 0 after completion. For example, set GLOB_CMD[7] = 1 (DIN = 0xBE80) to execute a software reset, which stops the sensor operation and runs the device through its start-up sequence. This sequence includes loading the control registers with their respective flash memory locations prior to producing new data. Reading the GLOB_CMD register (DIN = 0x3E00) starts the burst read sequence. Table 17. GLOB_CMD Bit Descriptions

Bit [15:12] [11:0] Description (Default = 0x0000) Not used. Data bits. Twos complement, 0.333 mg/LSB. Typical adjustment range = 0.3 g.
Gyroscope Automatic Bias Null Calibration
Set GLOB_CMD[0] = 1 (DIN = 0xBE01) to execute the automatic bias null calibration function. This function measures all three gyroscope output registers and then loads each gyroscope offset register with the opposite value to provide a quick bias calibration. All sensor data is then reset to 0, and the flash memory is updated automatically within 50 ms (see Table 17).
Gyroscope Precision Automatic Bias Null Calibration
Set GLOB_CMD[4] = 1 (DIN = 0xBE10) to execute the precision automatic bias null calibration function. This function takes the sensor offline for 30 sec while it collects a set of data and calculates more accurate bias correction factors for each gyroscope. After this function is executed, the newly calculated correction factor is loaded into the gyroscope offset registers, all sensor data is reset to 0, and the flash memory is updated automatically within 50 ms (see Table 17).

Internal Sample Rate
The SMPL_PRD register provides discrete sample rate settings using the bit assignments in Table 18 and the following equation: tS = tB x (NS + 1) For example, when SMPL_PRD[7:0] = 0x0A, the sample rate is 149 SPS. Table 18. SMPL_PRD Bit Descriptions
Bit [15:8] [7] [6:0] Description (Default = 0x0001) Not used Time base (tB) 0 = 0.61035 ms, 1 = 18.921 ms Increment setting (NS) Internal sample period = tS = tB x (NS + 1)
Digital Filtering
A programmable low-pass filter can provide additional noise reduction on the inertial sensor outputs. This filter contains two cascaded averaging filters that provide a Bartlett window, FIR filter response (see Figure 14). For example, set SENS_AVG[2:0] = 100 (DIN = 0xB804) to set each stage to 16 taps. When used with the default sample rate of 819.2 SPS, this value reduces the sensor bandwidth to approximately 16 Hz.

MAGNITUDE (dB)

08179-015
The default sample rate setting of 819.2 SPS preserves the sensor bandwidth and provides optimal performance. For systems that value slower sample rates, keep the internal sample rate at 819.2 SPS. Use the programmable filter (SENS_AVG) to reduce the bandwidth, which helps to prevent aliasing. The data ready function (MSC_CTRL) can drive an interrupt routine that uses a counter to help ensure data coherence at the reduced rates.

FREQUENCY (Ratio)
Power Management
Setting SMPL_PRD 0x0A also sets the sensor to low power mode. For systems that require lower power dissipation, insystem characterization helps users to quantify the associated performance trade-offs. In addition to sensor performance, this mode affects SPI data rates (see Table 2). Set SLP_CNT[8] = 1 (DIN = 0xBB01) to start the indefinite sleep mode, which requires a CS assertion (high to low), reset, or power cycle to wake up. Use SLP_CNT[7:0] to put the device into sleep mode for a specified period. For example, SLP_CNT[7:0] = 0x64 (DIN = 0xBA64) puts the ADIS16362 to sleep for 50 sec. Table 19. SLP_CNT Bit Descriptions

Dynamic Range
The SENS_AVG[10:8] bits provide three dynamic range settings for this gyroscope. The lower dynamic range settings (75/sec and 150/sec) limit the minimum filter tap sizes to maintain resolution. For example, set SENS_AVG[10:8] = 010 (DIN = 0xB902) for a measurement range of 150/sec. Because this setting can influence the filter settings, program SENS_AVG[10:8] and then SENS_AVG[2:0] if more filtering is required. Table 20. SENS_AVG Bit Descriptions

INPUT/OUTPUT FUNCTIONS
General-Purpose I/O
DIO1, DIO2, DIO3, and DIO4 are configurable, general-purpose I/O lines that serve multiple purposes according to the following control register priority: MSC_CTRL, ALM_CTRL, and GPIO_CTRL. For example, set GPIO_CTRL = 0x080C (DIN = 0xB308, and then 0xB20C) to configure DIO1 and DIO2 as inputs and DIO3 and DIO4 as outputs, with DIO3 set low and DIO4 set high. In this configuration, read GPIO_CTRL (DIN = 0x3200).The digital state of DIO1 and DIO2 is in GPIO_CTRL[9:8]. Table 21. GPIO_CTRL Bit Descriptions

Auxiliary DAC
The 12-bit AUX_DAC line can drive its output to within 5 mV of the ground reference when it is not sinking current. As the output approaches 0 V, the linearity begins to degrade (~100 LSB beginning point). As the sink current increases, the nonlinear range increases. The DAC latch command moves the values of the AUX_DAC register into the DAC input register, enabling both bytes to take effect at the same time. Table 23. AUX_DAC Bit Descriptions
Bit [15:12] [11:0] Description Not used Data bits, scale factor = 0.8059 mV/LSB Offset binary format, 0 V = 0 LSB
Input Clock Configuration
The input clock function allows for external control oversampling in the ADIS16362. Set GPIO_CTRL[3] = 0 (DIN = 0x0B200) and SMPL_PRD[7:0] = 0x00 (DIN = 0xB600) to enable this function. See Table 2 and Figure 4 for timing information.
Data Ready I/O Indicator
The factory default sets DIO1 as a positive data ready indicator signal. The MSC_CTRL[2:0] bits provide configuration options for changing the default. For example, set MSC_CTRL[2:0] = 100 (DIN = 0xB404) to change the polarity of the data ready signal on DIO1 for interrupt inputs that require negative logic inputs for activation. The pulse width is between 100 s and 200 s over all conditions.

DIAGNOSTICS
Self-Test
The self-test function allows the user to verify the mechanical integrity of each MEMS sensor. It applies an electrostatic force to each sensor element, which results in mechanical displacement that simulates a response to actual motion. Table 1 lists the expected response for each sensor, which provides pass/fail criteria. Set MSC_CTRL[10] = 1 (DIN = 0xB504) to run the internal self-test routine, which exercises all inertial sensors, measures each response, makes pass/fail decisions, and reports them to error flags in the DIAG_STAT register. MSC_CTRL[10] resets itself to 0 after completing the routine. The MSC_CTRL[9:8] bits provide manual control over the self-test function for investigation of potential failures. Table 25 outlines an example test flow for using this option to verify the x-axis gyroscope function. Table 25. Manual Self-Test Example Sequence
DIN 0xB601 0xB904 0xB802 0x0400 0xB502 0x0400 Description SMPL_PRD[7:0] = 0x01, sample rate = 819.2 SPS SENS_AVG[15:8] = 0x04, gyro range = 300/sec SENS_AVG[7:0] = 0x02, four-tap averaging filter Delay = 50 ms Read XGYRO_OUT MSC_CTRL[9] = 1, gyroscope negative self-test Delay = 50 ms Read XGYRO_OUT Determine whether the bias in the gyroscope output changes according to the expectation set in Table 1 MSC_CTRL[9:8] = 01, gyroscope/accelerometer positive self-test Delay = 50 ms Read XGYRO_OUT Determine whether the bias in the gyroscope changed according to the self-test response in Table 1 MSC_CTRL[15:8] = 0x00
Status
The error flags provide indicator functions for common system level issues. All of the flags are cleared (set to 0) after each DIAG_STAT register read cycle. If an error condition remains, the error flag returns to 1 during the next sample cycle. The DIAG_STAT[1:0] bits do not require a read of this register to return to 0. If the power supply voltage goes back into range, these two flags are cleared automatically. Table 26. DIAG_STAT Bit Descriptions

0xB501
Alarm Registers
The alarm function provides monitoring for two independent conditions. The ALM_CTRL register provides control inputs for data source, data filtering (prior to comparison), static comparison, dynamic rate-of-change comparison, and output indicator configurations. The ALM_MAGx registers establish the trigger threshold and polarity configurations. Table 30 gives an example of how to configure a static alarm. The ALM_SMPLx registers provide the numbers of samples to use in the dynamic rate-of-change configuration. The period equals the number in the ALM_SMPLx register multiplied by the sample period time, which is established by the SMPL_PRD register. See Table 31 for an example of how to configure the sensor for this type of function.
0x0400
0xB500
Zero motion provides results that are more reliable. The settings in Table 25 are flexible and allow for optimization around speed and noise influence. For example, using fewer filtering taps decreases delay times but increases the possibility of noise influence.
Memory Test
Setting MSC_CTRL[11] = 1 (DIN = 0xB508) performs a checksum verification of the flash memory locations. The pass/fail result is loaded into DIAG_STAT[6].

INTERFACE PRINTED CIRCUIT BOARD (PCB)
The ADIS16362/PCBZ includes one ADIS16362BLMZ and one interface PCB. The interface PCB simplifies the process of integrating the ADIS16362BMLZ into an existing processor system. J1 and J2 are dual-row, 2 mm (pitch) connectors that work with a number of ribbon cable systems, including 3M Part Number 152212-0100-GB (ribbon crimp connector) and 3M Part Number 3625/12 (ribbon cable). Figure 16 provides a hole pattern design for installing the ADIS16362BMLZ and the interface PCB onto the same surface. Figure 17 provides the pin assignments for each connector. The pin descriptions match those listed in Table 5. The ADIS16362 does not require external capacitors for normal operation, so the interface PCB does not use the C1/C2 pads (not shown in Figure 16).
23.75 21.24
Never attempt to unplug the connector by pulling on the plastic case or baseplate. Although the flexible connector is very reliable in normal operation, it can break when subjected to unreasonable handling. When broken, the flexible connector cannot be repaired. The AN-1041 Application Note provides more information about developing an appropriate mechanical interface design.
GYROSCOPE BIAS OPTIMIZATION
The factory calibration addresses initial bias errors along with temperature-dependent bias behaviors. Installation and certain environmental conditions can introduce modest bias errors. The precision autonull command (GLOB_CMD[4]) provides a simple predeployment method for correcting these errors to an accuracy of approximately 0.008/sec, using an average of 30 sec. Averaging the sensor output data for 100 sec can provide incremental performance gains, as well. Controlling device rotation, power supply, and temperature during these averaging times helps to ensure optimal accuracy during this process. Refer to the AN-1041 Application Note for more information about optimizing performance.
