Datasheet - Detailed Description
7.9 OTP Programming and Verification
Figure 9. OTP Programming Connection
Note: The maximum capacitive load at PROG in normal operation should be less than 20pF. However, during programming the capacitors
C1+C2 are needed to buffer the programming voltage during current spikes, but they must be removed for normal operation. To
overcome this contradiction, the recommendation is to add a diode (4148 or similar) between PROG and VDD as shown in Figure 9
(special case setup), if the capacitors can not be removed at final assembly.
Due to D1, the capacitors C1+C2 are loaded with VDD - 0.7V at startup, hence not influencing the readout of the internal OTP registers.
During programming the OTP, the diode ensures that no current is flowing from PROG (8V - 8.5V) to VDD (5V).
In the standard case (see Figure 9), the verification of a correct OTP readout can be done by analog readback of the OTP register.
As long as the PROG pin is accessible it is recommended to use standard setup. In case the PROG pin is not accessible at final
assembly, the special setup is recommended.
