USB2ANY: Can USB2ANY adaptor debug I2C with 1.8V?

Tiger Wang

Part Number: USB2ANY

Dear Sir,

I want to use USB2ANY I2C to debug my board, which voltage level is valid for USB2ANY I2C pin? it seem only 3.3V is supported from USB2ANY schematics, does it support 1.8V voltage level?

Thanks.

Which Evaluation Module (EVM)are you using the USB2ANY with? The team responsible for the EVM is the one that can answer your question.

David,
DS90UB953EVM and DS90UB954EVM has already builtin USB2ANY circuit on board. You don't need any external USB2ANY board. Jumpers would allow you configure for 1.8V I2C also.
Thanks,

Dear Vishy,

Thanks.

I understand 953_EVM and 954_EVM can be debugged by embedded USB2ANY module,but I want to use USB2ANY to debug my customized board without embedded USB2ANY module integrated.

Can standalone USB2ANY adapter debug my customized board ,which IO voltage is 1.8V?

Best regards！

David,

I looked at standalone USB2ANY schematic. The I2C pins are pulled up to 3.3V. Also, MSP430 MCU supply is also at 3.3V. See schematic below. So standalone USB2ANY I2C pins would not operate at 1.8V.

Thanks,

Vishy
