Ted Hsu

Part Number: LP87745-Q1

Tool/software:

Could you please assist with the OTP code for 8.8MHz switching, as the LP877452 is currently out of stock?

Hello Ted,

The frequency switching is not possible through SPI writes. You can refer to the following E2E for the same question as well.

What is the OTP version, where can I find it?

Hello,

OTP version means, new device with 8.8 MHz switching frequency.

Here is the 8.8 MHz Fsw device on ti.com
