12 Programming the AS5040
After power-on, programming the AS5040 is enabled with the rising edge of CSn with Prog = high and CLK = low. 16
bit configuration data must be serially shifted into the OTP register via the Prog-pin. The first “CCW” bit is followed by
the zero position data (MSB first) and the incremental mode setting as shown in Table 6. Data must be valid at the
rising edge of CLK (see Figure 14).
After writing data into the OTP register it can be permanently programmed by rising the Prog pin to the programming
voltage V PROG . 16 CLK pulses (t PROG ) must be applied to program the fuses (Figure 15). To exit the programming
mode, the chip must be reset by a power-on-reset. The programmed data is available after the next power-up.
Note: During the programming process, the transitions in the programming current may cause high voltage spikes
generated by the inductance of the connection cable. To avoid these spikes and possible damage to the IC, the
connection wires, especially the signals Prog and VSS must be kept as short as possible. The maximum wire length
between the V PROG switching transistor and pin Prog (see Figure 16) should not exceed 50mm (2 inches). To
suppress eventual voltage spikes, a 10nF ceramic capacitor should be connected close to pins Prog and VSS. This
capacitor is only required for programming, it is not required for normal operation.
The clock timing t clk must be selected at a proper rate to ensure that the signal Prog is stable at the rising edge of CLK
(see Figure 14). Additionally, the programming supply voltage should be buffered with a 10μF capacitor mounted
close to the switching transistor. This capacitor aids in providing peak currents during programming.
The specified programming voltage at pin Prog is 7.3 – 7.5V (see section 0). To compensate for the voltage drop
across the V PROG switching transistor, the applied programming voltage may be set slightly higher (7.5 - 8.0V, see
Figure 16).
