2 Capacitive sensing
2.1 Introduction to ProxSense®
Building on the previous successes from the ProxSense® range of capacitive sensors, the same
fundamental sensor engine have been implemented in the ProxFusion series.
The capacitive sensing capabilities of the IQS620 include:
Self-capacitive sensing.
Maximum of 3 capacitive channels to be individually configured.
o Prox and touch adjustable thresholds
o Individual sensitivity setups
o Alternative ATI modes
Enhanced SAR user interface:
o For passing the SAR qualification
o Movement sensing to distinguish between stationary in-contact objects and human
interference
o Quick release detection feature (fully configurable)
o GPIO output of SAR activation (on pin2: GPIO0) for MCU interrupt capability
Discreet button UI:
o Fully configurable 2 level threshold setup – Traditional Prox & Touch activation
levels.
o Customizable filter halt time
2.2 Channel specifications
The IQS620 provides a maximum of 3 channels available to be configured for capacitive sensing.
Each channel can be setup separately according to the channel’s associated settings registers.
There are two distinct capacitive user interfaces available to be used.
a) Self capacitive proximity/touch UI (always enabled)
b) SAR UI
When the SAR UI is activated (ProxFusion Settings4: bit7):
Channel 0 is used for as the main capacitive sensing channel for SAR detection.
Channel 1 is used for capacitive movement detection. This is used to improve the SAR
detection such as quick release detection.

3 Hall-effect sensing
3.1 Introduction to Hall-effect sensing
The IQS620 has two internal Hall-effect sensing plates (on chip). No external sensing hardware is
required for Hall-effect sensing.
The Hall-effect measurement is essentially a current measurement of the induced current through
the Hall-effect-sensor plates produced by the magnetic field passing perpendicular through each
plate.
Advanced digital signal processing are performed to provide sensible output data.
Two threshold levels are provided (prox & touch).
Hall-effect output is linearized by inverting signals.
North/South field direction indication provided.
Differential Hall-Effect sensing:
o Removes common mode disturbances
o North-South field indication
3.2 Channel specifications
Channels 4 and 5 are dedicated to Hall-effect sensing. Channel 4 performs the positive direction
measurements and channel 5 will handle all measurements in the negative direction. These two
channels are used in conjunction to acquire differential Hall-effect data and will always be used as
input data to the Hall-effect UI’s.
There are two distinct Hall-effect user interfaces available:
a) General Hall-effect sensing
b) Hall-effect switch UI

5 Temperature sensing
5.1 Introduction to temperature sensing
The IQS620 provides temperature sensing capabilities which can be used for temperature change
monitoring or as an absolute temperature sensor (requires individual calibration). The use of the
temperature sensor is primarily to reseed other sensor channels to account for sudden changes in
environmental conditions.
The IQS620 uses a linearly proportional to absolute temperature sensor for temperature
measurement. The temperature output is given by,

5.2 Channel specifications
The IQS620 requires only external passive components to do temperature sensing (no additional
circuitry/components required). The temperature UI will be executed using data from channel 3 if
correctly setup for temperature sensing.

6 Device clock, power management and mode operation
6.1 Device main oscillator
The IQS620 has a 16MHz main oscillator (default enabled) to clock all system functionality.
An option exists to reduce the main oscillator to 4MHz. This will result in all system timings, charge
transfers and sample rates to be slower by half of the default implementations.
To set this option this:
o As a software setting – Set the System_Settings: bit4 = 1, via an I2C command.
o As a permanent setting – Set the OTP option in FG Bank 0: bit2 = 1, using Azoteq USBProg
program.
6.2 Device modes
The IQS620 supports the following modes of operation;
Normal mode (Fixed report rate)
Low power mode (Reduced report rate)
Ultra-low power mode (Only channel 0 is sensed for a prox)
Halt mode (Suspended/disabled)
Note: Auto modes must be disabled to enter or exit halt mode.
The device will automatically switch between the different operating modes by default. However this
Auto mode feature may be disabled by setting the DSBL_AUTO_MODE bit (Power_mode_settings
0xD2: bit5) to confine device operation to a specific power mode. The POWER_MODE bits
(Power_mode_settings 0xD2: bit4-3) can then be used to specify the desired mode of operation.
6.2.1 Normal mode
Normal mode is the fully active sensing mode to function at a fixed report rate specified in the Normal
Mode report Rate (0xD3) register. This 8-bit value is adjustable from 0ms – 255ms in intervals of
1ms.
Note: The device’s low power oscillator have an accuracy as specified in section 9.
6.2.2 Low power mode
Low power mode is a reduced sensing mode where all channels are sensed but at a reduced sample
rate. The sample rate can be specified in the Low Power Mode report Rate (0xD4) register. The 8-
bit value is adjustable from 0ms – 255ms in intervals of 1ms. Reduced report rates also reduce the
current consumed by the sensor.
Note: The device’s low power oscillator have an accuracy as specified in section 9.
6.2.3 Ultra-low power mode
Ultra-low power mode is a reduced sensing mode where only channel 0 is sensed and no other
channels or UI code are executed. Set the EN_ULP_MDE bit (Power_mode_settings: bit6) to enable
use of the ultra-low power mode. The sample rate can be specified in the Low Power Mode report
Rate (0xD5) register. The 8-bit value is adjustable from 0ms – 4sec in intervals of 16ms.
Wake up will occur on prox detection on channel 0.
6.2.4 Halt mode
Halt mode will suspend all sensing and will place the device in a dormant or sleep state. The device
requires an I2C command from a master to explicitly change the power mode out of the halt state
before any sensor functionality can continue.

6.2.5 Mode time
The mode time is specified in the Auto Mode Timer (0xD6) register. The 8-bit value is adjustable
from 0ms – 2 min in intervals of 500ms.
6.3 Report rates
6.3.1 Calculation of each mode’s report rate

6.4 System reset
The IQS620 device monitor’s system resets and events.
a) Every device power-on and reset event will set the Show Reset bit (System flags 0x10: bit7)
and the master should explicitly clear this bit by setting the ACK_RESET (bit6) in System
Settings.
b) The system events will also be indicated with the Global events register’s SYS_EVENT bit
(Global events 0x11: bit5) if any system event occur such as a reset. This event will
continuously trigger until the reset has been acknowledged.

7 Communication
7.1 I2C module specification
The device supports a standard two wire I2C interface with the addition of an RDY (ready interrupt)
line. The communications interface of the IQS620 supports the following:
Streaming data as well as event mode.
The master may address the device at any time. If the IQS620 is not in a communication
window, the device will return an ACK after which clock stretching may be induced until a
communication window is entered. Additional communication checks are included in the
main loop in order to reduce the average clock stretching time.
The provided interrupt line (RDY) is an open-drain active low implementation and indicates
a communication window.
7.2 Device address and sub-addresses
The default device address is 0x44 = DEFAULT_ADDR.
Alternative sub-address options are definable in the following one-time programmable bits:
OTP Bank0 (bit3; 0; bit1; bit0) = SUB_ADDR_0 to SUB_ADDR_7
a) Default address:

0x4C = DEFAULT_ADDR OR SUB_ADDR_4
0x4D = DEFAULT_ADDR OR SUB_ADDR_5
0x4E = DEFAULT_ADDR OR SUB_ADDR_6
0x4F = DEFAULT_ADDR OR SUB_ADDR_7

Master command structure and runtime event handling flow diagram
It is recommended that the master verifies the status of the System_Flags0 bits to identify events
and resets. Detecting either one of these should prompt the master to the next steps of handling the
IQS620.
Streaming mode communication is used for detail sensor evaluation during prototyping and/or
development phases.
Event mode communication is recommended for runtime use of the IQS620. This reduce the
communication on the I2C bus and report only triggered events.

10.5MSL Level
Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions for some
semiconductors. The MSL is an electronic standard for the time period in which a moisture sensitive
device can be exposed to ambient room conditions (approximately 30°C / 85%RH see J-STD033C
for more info) before reflow occur.
