MSP 432 New Design suggestion

Alexey Bagaev

Other Parts Discussed in Thread: CC1310, CC3200, CC2650, CC2640

Hi TI team,

I have some thoughts about MSP432 hardware design. First of all I know about upcoming CC1310 and existing CC3200. But it would be nice to add to MSP432 I2S port and external parallel interface support (fully utilizing 2-4 8 bit ports or 1-2 16-bit ports) with additional output clocking supply and serial shift circuits with IRQ (primary for low resolution video camera sensors). The new CC1310 'chameleon' routing is a good choice but probably is not the most robust I expect.

And as always it would be nice to see sub 2-uA LPM-3 mode in MSP-432.

Thanks,

Alex.

Hi Alex,

We always value this kind of feedback, thank you so much. Maybe someone from our Marketing team will contact you offline to get more information on your application / End Equipment.

Thanks again,

David

Talking about suggestion for MSP432. How about add cJTAG?

Based on documentation for the new CC1310 and CC2650 cJTAG is implemented on them. But as you can see TI does not recommend to discuss such matters in public.

Yes. CC26xx/CC13xx has cJTAG and I am using CC2640 for half a year. I believe cJTAG will be very popular for embedded system in the future.

I also think the I/O mapping mechanism of CC26xx is very good. For example, you can assign any one of GPIO pins as I2C.SCK. But MSP432 is based on MSP430. The port structure is less flexible. In my past experience, it is inconvenient, especially when you need interrupts on I/O pin. Only certain ports support interrupt.

There are many new things to come from TI. And it takes a sufficient amount of time for researching, developing, testing, documenting, software support... And there are many big customers who have already invested in existing infrastructure and they also don't want to be outdated (have outdated solutions). But the technological advancement cannot be suspended nowadays by any single company or customer .

After some additional research I discovered Port Mapping Controller :) on MSP432 and achieved sub 2 uA and even sub 1 uA in LPM3 by manipulation with Voltage Supply Supervisor.
