ISL29501-ST-EV1Z Evaluation Board Manual
1. Functional Description
The ISL29501-ST-EV1Z is both a reference design and evaluation board that provides a single platform to
evaluate the features of the ISL29501. The ISL29501-ST-EV1Z circuit board and supplied enclosure deliver
maximum electrical and optical performance.
The system sends out light pulses through the emitter LED and receives returned light pulses that reflected off a
target. The difference in phase of the emitted signal and the return signal is converted to distance by the ISL29501
and is graphed in the evaluation software. The magnitude of the return signal is graphed as well. This and
additional data is available in chip registers, see UG054, ISL29501 Evaluation Software Manual for additional
details.
1.1 Operating Features
The ISL29501-ST-EV1Z evaluation board is shown in Figure 4 and Figure 5. The hardware enable function is
controlled by a software switch, which can be overridden shorting J9 pins 1 and 2. See the schematic for details. A
Power-Good (PG) LED indicates that the LDO is regulating properly.
1.1.1 External Power Supply
For high current/high duty cycle setups, USB power may not be able to power the board. In the default condition,
jumper J10 shorts pins 1 and 2 to connect to USB power to the LDO. To power the board with an external power
supply, remove this jumper and connect the positive (+) terminal to J10-2 and the negative (-) to J10-4.
If you want to bypass the LDO and power the ISL29501 directly with a power supply, remove the jumper on J10.
Use J10-4 for your ground connection and apply the positive voltage to TP7.
1.1.2 External Microprocessor
For debug of customer written software, it might be useful to connect the Sand Tiger to a different microprocessor.
The I2C pins SCL and SDA are available on pins J4-4 and J4-3, respectively. The remaining support pins are
available on J5: SS - J5-4, IRQ - J5-3, and CEn - J5-2. The support pins are generally connected to GP pins on
the microprocessor. SCL and SCL are compatible with 1.8V microprocessors but unfortunately the support pins
require 3V signaling.
1.1.3 System Calibration
Before meaningful measurements can be made, the calibration registers in the chip need to be loaded. This can
be done in two ways. The first is to load a profile that contains data into the GUI. This could be one of the Renesas
provided profiles or one that was saved previously by the user. See UG054, ISL29501 Evaluation Software
Manual for further details. The second is to calibrate the board directly.
1.1.4 Calibrating Sand Tiger
There are three separate standard calibrations that need to be executed to calibrate the system. These are
magnitude, crosstalk, and distance calibrations.
1.1.4.1 Magnitude Calibration
Magnitude calibration is done after the emitter current and duty cycle settings are programmed. It is a dark (no
light) calibration that takes less than 1s to run. Run this calibration from the GUI.
1.1.4.2 Crosstalk calibration
Crosstalk is defined as a signal that reaches the ISL29501 chip directly without bouncing off the target. This can
be electrical or optical. At close range and large return signal values, crosstalk has a minor impact on distance
measurements. At the far end of the distance range, the crosstalk might exceed the signal, adding error to
measurements.

UG055 Rev.1.00 Page 4
Apr 5, 2022
ISL29501-ST-EV1Z Evaluation Board Manual
For this calibration, the user makes a distance measurement with the return signal blocked from reaching the
photodiode. This can be done in two ways. The first is to cover the emitter or photodiode optically preventing any
of the emitted signal from reaching the photodiode. The second is to point the board toward infinity so there is no
return signal. Care must be taken since small amounts of signal are returned by objects up to 4 meters away. The
emitting angle of the light is ±3° so you must be sure that there are no objects within this cone when doing this
calibration.
Because the chip sees none of the emitted signal, anything received is crosstalk. Run this calibration from the GUI
after running Magnitude calibration.
1.1.4.3 Distance Calibration
Variation in delay of emitters, photodiodes, and the ISL29501 changes the signal path delay. To compensate for
this, a reference point at a known distance needs to be established. This reference is calculated during distance
calibration. The process involves making a distance measurement at a known distance. While it is not critical it is
best to use a reference distance about 25% of the intended range. The GUI writes the correct registers that
establish the reference distance inside the chip.
It is important that there are no objects inside the ±3° emitting angle other than the target.
When these calibration registers are written, all succeeding distance has this value subtracted real time from the
measured value. Run this calibration from the GUI after running crosstalk calibration. See UG054, ISL29501
Evaluation Software Manual for details on how to run the calibrations in the GUI.
1.2 Operating Range
The circuit board contains an LDO to convert the input voltage to the ISL29501 operating voltage range, 2.7V -
3.3V. By default the board is configured for USB power but can be alternately powered by an external power
supply. The LDO resistors are ratioed to create a 3.0V power rail. All other set-up conditions can be configured
through the chip registers and evaluation software.
1.3 Quick Start Guide
To start making distance measurements follow these simple steps.
1. Plug the USB cable into the reference design and the PC.
2. Point the emitter toward the desired target.
3. Double click TOF.exe to start the GUI.
4. From the GUI click on File -> Load Profile -> filename to load safe initial register settings and calibration data.
5. Click either Start or Step to begin making distance measurements.
1.4 Changing Settings
When the board is running and making measurements, the user may want to change settings. The user has the
ability to change any of the chip registers with the evaluation software, see UG054, ISL29501 Evaluation Software
Manual for details. Important: If the pulse duty cycle or the emitter current is changed, the user must redo the
standard calibrations. This process is described in the sections under Calibrating Sand Tiger.

1.5 Sand Tiger Enclosure
The Sand Tiger chassis allows easy handling of the board to make distance measurements. The threaded hole fits
most camera tripod screws, which create a stable mount for precision measurements and characterization. The
holes in the top isolates the emitter and photodiode to minimize optical crosstalk. The chassis top connects to the
bottom with an interference fit. It is snug but the two can be easily separated by hand. Two threaded 4-40 holes
are provided to allow attachment of glass. Shown on the side are a micro USB that connects to a PC to run the
evaluation software and the power-good LED.

2.1 PCB Layout Guidelines
The ISL29501-ST-EV1Z PCB layout has been optimized for electrical and thermal performance. Care needs to be
placed in decoupling circuits and noise isolation. Sand Tiger follows good design techniques but additional
suggestions are available in AN1917, ISL29501 Layout Design Guide.
Figure 5. Sand Tiger Board (Bottom Side)[1]
1. Visible on the bottom side of the board are the emitter LED and photodiode. Each is surrounded by a brass tube. These tubes are grounded
and serve as terminators for any electric fields. They prevent crosstalk from the emitter to the photodiode.

The measured distance drifts with changes in temperature as shown in Figure 14. The ISL29501 has temperature
compensation built into the chip. This is an advanced calibration, which involves collecting temperature vs.
distance data and programming the compensation registers. Initially Renesas generates these coefficients from
customer collected data. The process for collecting data is described in AN1967, ISL29501 Temperature and
Ambient Data Collection.
Renesas strongly recommends that customers evaluate these parameters as a last step in their evaluation. To
avoid temperature effects low integration times, reg 0x10 < 0x06 should be used.
