AS5046 12-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER
Adapter PCB Operation Manual
Output Modes:
Programming (zapping) the Chip:
For programming the AS5046, 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 AS5046 demo board (available separately), where all
the programming timings are generated by the onboard microcontroller.
AS5046 Adapter PCB Layout and Component Placement:
The PCB has several connection options. All required pins are
accessible via the two 100mil- connectors J1 and J2.
These connectors are 600mil apart, which allows them to be
soldered to a wide 16-pin DIL IC socket for easier access or ribbon
cable connection.
Furthermore, J2 (pins 3...9) fit to the AS5046 demo board and
allow this PCB to be used as external encoder.
The hole in the PCB underneath the chip allows centering of a
6mm diameter magnet.
A Vout Led and voltage regulators are optional.
Minimum required components are C4 (1µF) and the CSN pull-
down R7 (0…4k7).

Absolute angle information
To access the 10-bit absolute angle information, an external microcontroller must be connected as shown in Figure
5. Make sure that the controller is able to drive the CSn pin with the connected pull-down resistor (R7). If
necessary, remove this resistor.
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 AS5046 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).
Analog output
No additional components are required. The voltage at the Vout pin (pins 3 of J1) indicates the position of the
encoder. (see datasheet).
