Adapter PCB Operation Manual
AS5043
10 BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER
1 The AS5043 adapter PCB:
The AS5043 adapter PCB is a simple circuit allowing customers to test and evaluate the AS5043 rotary encoder
rapidly without having to build their own test fixture or PCB.
The PCB can be used as standalone unit or plugged onto the AS5043 demo board as external encoder.
For Standalone operation, it can be supplied with 3.3V, 5V or 7,5...12V DC supply voltages.
Features:
100mil connector for direct connection to AS5043 demo board
Provision for a 600mil DIP socket
Hole in PCB to center a 6mm magnet at the bottom of the IC
LED for MagRng output
On-board 5V linear voltage regulator for 7,5...12V supplies
9V battery connector for standalone operation
Dimensions: 35mm x 37mm (1.38 x 1.46 inch)
Revision A.02, 04. Jul 06

    Mode input. Select between low noise DI_PD, Mode (open, low) and high speed (high) mode. The AS5043 can be configured to specific customer Internal pull-down resistor requirements by programming the integrated OTP DI_PU, Chip Select, active low; Schmitt-Trigger (one time programmable) register.

    AS5043 10-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER Adapter PCB Operation Manual 5 Principle of Operation The AS5043 chip consists of a ring of hall 3.9 mm 3.9 mm elements, placed at the center of the IC at a circle diameter of 2.2mm (86.6mil).
  • Page 4 AS5043 10-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER Adapter PCB Operation Manual 6 AS5043 Adapter PCB Schematic: Figure 5: AS5043 Adapter PCB schematic For normal operation, the only required external components are the buffer cap at VDD3V3 (C4) and the pull-down resistor for CSn (R7; 0Ω….4k7).
  • Page 5 The clock rate can be as high as 1MHz. There is no minimum clock rate. Data can also be clocked manually. The digital I/O's of the AS5043 are buffered by VDD5V, therefore the digital I/O's of the controller should be at the same voltage level (see power supply options table).

  • Page 7 Adapter PCB Operation Manual 8 AS5043 Demoboard The AS5043 Demoboard is a complete rotary encoder system with built-in microcontroller, USB interface , 4-digit 7-segment display and a LED displaying the magnitude range. It also supports external AS5043 applications, such as the AS5043 adapter PCB or in-system AS5043 customer applications that can be connected to the demoboard and displayed, modified and permanently programmed using the AS5043 Demoboard Software.
  • Page 8 (see: 7 Supporting tools) Connecting the AS5043 adapter PCB to the demoboard The AS5043 Adapter PCB is intended as a standalone device that allows easy and quick testing of the AS5043 without the need of having to make your own PCB.
  • Page 9 AS5043 10-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER Adapter PCB Operation Manual If you use the Adapter PCB as external encoder for the AS5043 demoboard with an extension cable or experience data transmission errors, it is requested to configure the Adapter PCB for 3.3V supply voltage.
  • Page 10 (see: 7 Supporting tools) The AS5043 Adapter PCB can be read as “external encoder” in the same way as the internal encoder. Switching from internal to external encoder can be done on the bottom left corner of the demoboard software screen: Encoder = onboard / external.
