1. General Description
The AS5013 is a complete Hall Sensor IC for smart navigation key applications to meet the low
power requirements and host SW integration challenges for products such as cell phones and
smart handheld devices. Due to the on chip processing engine, system designers are not tasked
with integrating complex SW algorithms on their host processor thus leading to rapid
development cycles.
The AS5013 single-chip IC includes 5 integrated Hall sensing elements for detecting up to ±2mm
lateral displacement, high resolution ADC, XY coordinate and motion detection engine combined
with a smart power management controller.
The X and Y positions coordinates and magnetic field information for each Hall sensor element
are transmitted over a 2-wire I²C interface to the host processor.
The AS5013 is available in a small 16-pin 4x4mm QFN package and specified over an operating
temperature of -20 to +80°C.

Board Descriptions
The AS5013 demo board consists of an EasyPoint™ module from Speedtech and an USB
interface PCB. The whole system is USB powered.
Once plugged on a PC running Windows, the AS5013 demo board works like a standard three-
buttons analog HID joystick, and can be used by any game or application supporting two-axis
analog joysticks under Microsoft Windows.

knob acts like an analog joystick, sending progressive XY coordinates
to Windows via USB.
Button EP (EasyPoint™ module push)
The EasyPoint™ module push button is used in different ways:
Mode 0 (default): Button EP emulates the standard HID button I (simultaneously with
Button ). Thus when using the AS501x evaluation software, button EP emulates the
left mouse button
Mode 1: Button EP is disabled. Button is still active as standard HID button I.
Buttons , , :
Those switches are standard HID gamepad buttons I, II and III. When using the AS501x
evaluation software, button emulates the left mouse button, and button emulates the right
mouse button.

Direction Switch
The demo board can be used as a standard game pad when held horizontally, or as a remote
control or mobile phone when held vertically. Select the orientation by changing the position of
switch SW1. The actual position is indicated by the LEDs DS1 (Vertical) or DS2 (Horizontal).

When the position SW1 is changed, a zero position calibration is performed: a new zero position
will be set, the actual mechanical position of the knob is considered as the coordinate (0,0). This
procedure is necessary to compensate an inaccurate centering of the module’s knob. The
automatic centering calibration is performed each time the demo board is powered on as well.
Center LED and Hall Push LED
The Center LED is ON when the knob coordinate is exactly (0,0) . This coordinate is after
calibration. The Hall Push LED is ON when the EP button of the module is pushed and detected
via the hall sensors only. This function doesn’t use the dome switch contact of the module, but
the magnetic field change on the vertical direction. The Hall push LED is enabled in mode 0, 1
and 2 only. See next chapter for information about the demo board modes.
3. How to get the kit running
First Steps
1. Install the Evaluation Software. The Evaluation Software is located on the USB Stick or
can be downloaded from the ams homepage. For detailed instructions refer to the
Evaluation Software Manual.

2. Connect the demo board to the PC using the USB cable
3. Start the Mouse Emulator and try the different Plug-Ins. For detailed instructions refer to
the Evaluation Software Manual.
Advanced Steps and Information
The demo board is listed as a composite HID device in the Windows Device Manager:
Windows detects as a standard HID-compliant game controller. This part doesn’t
need any driver.
Windows detects as well an HID-compliant device. This part doesn’t need any driver.

Demoboard modes
The AS5013 Demoboard can be configured in different ways without any software.
Mode 0: Without pressing any key, power up the demoboard with the USB cable. HID
Joystick button I is controlled by the EP button (from the EasyPoint™ module) and
Button .
Mode 1: Push and hold Button and power up the demoboard with the USB cable.
The LED “Center” blinks 4 times. HID Joystick button I is controlled by the Button
only. EP button is disabled
Mode 2: Push and hold Button and power up the demoboard with the USB cable.
The LED “Hall Push” blinks 4 times. HID Joystick button I is controlled by the Button ,
and by the “Hall Push” function. EP button is disabled.

The “Hall Push” is an algorithm running in the demoboard MCU, reading the five Ha ll
Element C1..C5, and determines if the EP button has been pushed, without any
electrical contact. The restriction of this mode is that the detection is working when the
EasyPoint™ module button is pushed on the center position area.
Mode 3: Push and hold Button and power up the demoboard with the USB cable.
The LED “Center” and “Hall Push” blink 4 times simultaneously.
This mode is similar to Mode 0, but the I²C communication between the MCU and
AS5013 is restricted to XY coordinate exchange only. The Hall Push function is totally
disabled.
This mode is used for debug mode, if timing analysis, with e.g. an oscilloscope, is
required, and simplifies the readout of signal and timing interpretation.
Firmware update mode: Push and hold Button simultaneously and power up
the demo board with the USB cable.
All the LEDs are ON. The AS5013 is in “Bootloader mode”. This mode is used to update
the firmware of the demo board if a new file is available on the ams website:
Firmware update:
To update the firmware, just open the AS501X Evaluation Software 4.1.6 or newer and connect
the demoboard with the USB cable while pressing all three buttons as shown below. A window to
choose the firmware file will pop up automatically.

4. Schematics
Figure 5:
AS5013_DB_2.1 Schematics
The microcontroller C8051C320 (U1) from SiLabs includes an on-chip USB interface. The
firmware is stored in its internal flash memory (16kB).
The whole power supply is taken from the USB bus by the microcontroller, and converts it
internally to 3.3V. No external LDO is required. The AS5013 is directly powered (VDD and
VDDp) by this 3.3V supply.
Connector J4 is used if an external MCU has to be connected to the AS5013 of the demo board,
instead of the C8051F320. In that case, cut the PCB tracks (bottom side) to disconnect the
N40P112 module from the MCU.

Disconnecting the Module from the MCU
Connector J1 is not used and connector J2 is used for ISP programming of the microcontroller
only. All the switches (dome switch: Button EP, Button I, Button II, Button III) are connected
directly to the microcontroller. The unique I²C serial bus (SCL, SDA) controlled by the C8051
microcontroller is used for the EasyPoint
TM
module (AS5013). The interrupt output INTn is
connected directly to the MCU interrupt input.
