Adapter PCB Operation Manual
1 The AS5040 adapter PCB:
The AS5040 adapter PCB is a simple circuit allowing customers to test and evaluate the AS5040 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 AS5040 demoboard as external encoder.
For Standalone operation, it can be supplied with 3.3V, 5V or 7,5...12V DC supply voltages.
Features:
Revision A.03 04. Jul.06
100mil connector for direct connection to AS5040 demoboard
Provision for a 600mil DIP socket
Hole in PCB to center a 6mm magnet at the bottom of the IC
LEDs for Incremental outputs A,B, Index
LED for PWM output
LEDs for magnet status outputs MagInc, MagDec
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)

... For programming the AS5040, 3 digital signals are required: CSn, Prog and CLK (see datasheet). For permanent writing, VPROG must be elevated to 7.5V during the programming cycle. For immediate programming, this PCB can be connected directly to the AS5040 demoboard (available separately), where all the programming timings are generated by the onboard microcontroller.

... It is possible to write "1"s into the OTP register at subsequent programming cycles. However, a programmed "1" cannot be cleared any more after programming. Note that the chip will not be programmed, as long as no programming voltage is applied to Vzapp, although the software will issue a warning message that the chip will be permanently programmed.

... Higher operating voltages can be handled with an external voltage regulator (e.g. > 7,5V with an external 78L05). The maximum output voltage level on the A,B and Index pins corresponds to the voltage at pin VDD5V. Figure 11: Incremental Outputs and power supply options Revision A.03 04.
