MCF8329EVM: Details and early launch queries

Part Number: MCF8329EVM
Other Parts Discussed in Thread: MCF8329A, MCF8316A

Hello TI experts,

Great to finally see MCF8329 getting launched. I have questions as below: 

1. MCF8329EVM page still shows description as MCT8329. I just want to make sure that I'm ordering correct evm for sensorless foc, Integrated control chip. 

https://www.ti.com/tool/MCF8329EVM

2. MCF8329 uses single shunt resistor for sensing current where as in instaspin foc I have seen 3 current sense resistors. I understand that computations increase with reduction of current sense resistors. Could you please advise if it makes any difference in sensorless foc performance? 

3. By when MCF8329A chip will be in stock? 

Thanks.

    Thank you for pointing out the issue with the MCF8329EVM description on the webpage, we will look into addressing this. Ordering the MCF8329EVM listed on the page that you linked will provide you the evaluation board for the MCF8329A.

    The FOC algorithm integrated within the MCF8329A device has been optimized for use with a single shunt resistor. The MCF8329A should not have any difference in FOC performance compared to our other sensorless FOC devices which use 3 current sense amplifiers like the MCF8316A.

    There should be >200 MCF8329A chips in stock on ti.com.
