In System Programming Notice for OTP
The In System Programming technology is valid for OTP chip. The Programming Interface of the OTP chip must be set on user’s application PCB, and users can assemble all components including the OTP chip in the application PCB before programming the OTP chip. Of course, it’s accessible bonding OTP chip only first, and then programming code and finally assembling other components.
Since the programming timing of Programming Interface is very sensitive, therefore four jumpers are needed (VDD, VPP, SDA, SCK) to separate the programming pins from the application circuit as shown in the following diagram.
The recommended steps are the followings:
- The jumpers are open to separate the programming pins from the application circuit before programming the chip.
- Connect the programming interface with OTP writer and begin programming.
- Disconnect OTP writer and shorten these jumpers when programming is completed.
