IWRL6432AOP: Quesition on HW desgin with other circuit

Chris Meng

Part Number: IWRL6432AOP

Tool/software:

Hi,

My customer is evaluating to integrate IWRL6432AOP to their system. To reduce the cost, they want to design IWRL6432AOP with other function circuit.

Below are the items I think customer need to take care.

1. the component size must not interfere with the field of view of the antenna

2. Dedicate power device for 1.2V/1.8V power rail of IWRL6432AOP.

What else need customer to take care when doing the HW design?

Thanks,

Chris

Hi Chris,

If they are using 3.3V I/O, dedicated power supply will also be required for 3.3V. And the communication interface for loading the program. Please kindly refer to the TI EVM schematic below for a better understanding.

Ankit,

Do you mean customer need use dedicated LDO to output 3.3V I/O power supply to IWRL6432AOP? Can customer use the 3.3V power rail on the board which also inputs to other device?

Thanks,

Chris

Hi Chris,

Apologies for the delay in reply, I was sick and OOO for few days. The power rail on the board used to supply 3.3V to the other devices can be used as along as the peak current requirement, noise and ripple specifications are met.
