Please, more Tiva Series and options.

The selections for Cortex-M4 from Texas is very poor compared with others

And (some) here note the (disappearance) of Cortex-M3,  (absence) of low-cost Cortex-M0, and (silence) as regards newer Cortex-M7.

You appear to have, "locked yourself in - to one vendor - all the time!"   Is it possible (even likely) that any single vendor would - at all times - produce the best: Feature, Function, Price, Availability, Support, Documentation & Eval-Board matrix?

Selection of a (proper) multi-vendor welcoming IDE - is a good first step toward evaluation of the broader marketplace - so that your "MCU selection" is greatly improved...   Self-limiting may not prove, "best/brightest."

Hello Ari,

While it may be true for Cortex M4 family of devices, TI has other devices from R4, C28xx and 8-16 bit family of devices. This allows the customer to leverage the maximum for the specific application.

May I (ever so gently) challenge the correctness/wishfulness of, "Leverage the maximum" for the application?

Our findings - ARM's overwhelming capture of cell, tablet & newer markets throws off so much cash - so much new design effort - that "down-grade" to 8-16 bit (single sourced) devices makes little sense.  ARM is smart enough to far better enable any such, "leverage to the maximum" than ANY single (locked in time - mais non?) vendor.

Simple review of the "sales numbers/market share" of various ARM vendors (individually and in total) shows where the "real leverage" resides...

Hello cb1,

Yes, ARM is predominantly taking up the market through it wide offering but there are still niche markets for the other devices. There would be more ARM family of uC in the near future (not sure on release dates)

Hi Amit,

We must keep in mind - that poster (specifically) requested, "More Tiva (thus ARM) series" - and (several) here have noted the "dearth" of ARM offerings. (unwise to pretend/avoid the fact that: M0, M3, M7s are missed...)  (M3's specifically due to their small packages (48QFP or larger SRAM)

Poster wrote, "even Spansion" - but just as this vendor acquired MSP family (from Euro firm - as I recall) Spansion acquired the ARM efforts of Fujitsu - long a "player" in the ARM MCU market - thus the "even" may register as "unknowing & unfair."

Amit,
So, Texas don't have plans for a new series of Tiva for low power or for digital power. If so, It's a shame, Texas has the best support just need to have better Microcontrollers. For me MSP430 and C28x are obsolete compared with the Cortex-M0 and the Cortex-M4/M7.

Ari.

Hello Ari,

I do understand Low Power, but could you explain Digital Power?

Regards
Amit

Amit,

I mean Microcontroller for Digital power conversion and Real time digital control in general. These Microcontrollers need a CPU with DSP instruction set and specialised peripherals like high resolution PWM, high speed ADC (4 MSPS or more), analog comparators with internal DAC, etc. Like Texas C28x family for example.

ST, Freescale, Analog devices and Infineon have done it.

I'm sure that sooner or later Texas will do also,  and I am also sure that it will be the best.

Ari.

 Hi Ari, just curious about, why MSP and C2000 are as you say obsolete?

 I find them specialized over power/communication control for C2000 and ULTRA low power for MSP430 but MSP430 sometimes is better than ARM. I don't find them obsolete, smallest power and casing too.

 In case you need highest power what about OMAP series? Both DSP and ARM.

 About case yes a low cost TIVA possibly pin to pin to old stellaris can be a good deal.

 In term of computing power I am sceptic about C2xxx to arm comparison they are two different things. Otherwise DSP are cheap than TIVA when one need do DSP, TI has too many devices just Freescale/AD compete with but on DSP Freescale is not so aggressive. The other side Analog Devices has a lot of specialized DSP but don't overlap some TI only field.
