LP8556TM-EVM: Latest EVM schematic / layout and device option (NVM)

Sean, 

Customer showed his EVM (LP8556TM) but it looks newer than which you told. Also the marking of the chip is "34XK 56E2" as customer informed. Please find below attached picture. 

And another question, for the E2PROM overwrite, can we overwrite the NVM contents of this "E2" (or any other than E5) chip ? 

I have "regular" E2PROM writing procedure (with 6V write biasing) but, will it work for non E5 chip ?  Customer wish to try customized setup as bench evaluation purpose. Or, are they need to replace to E5 chip ? 

Thanks, Hiroaki 

Hi Hiroaki,
The document is the latest that I have, if there is mismatch with your board, you may need to identify the connection. The mark on picture shows the "PWM" and "GND" connection is right.
LP8556 only has EPROM inside which can be only written once. If you want to customized the configuration, you need to choose E5 version.
Best Regards
Sean

OK, I'll let customer to look his board and add jumper if necessary. And, also evaluate the device operation as overwriting necessary registers. 

Thanks ! Hiroaki
