It's a short term benefit thinking :-(
But that's because marketing people decide, not tehnicians and all
what they care about are the numbers that benefit to their salary.
If the numbers don't fit they leave for another job.
However, they don't understand that small volume customers,
independent developers and students are those who can drive with
their ideas the high-volume sales up ...

that they can design chips for the largest markets and make the most
money by focusing on those large customers. In fact, some years ago
when cell phones were just starting to take off, TI realized the full
potential of the cell phone DSP market and decided to orient the
***entire*** company towards serving that market. They bought and
sold divisions just to optimize their position in that market. In
addition all new development in the entire DSP line was realigned to
two lines, the chips that go in the cell phones and the chips that go
into cell base stations. The rest is history...
It is actually a diversion from their main focus for them to be
selling to *any* other market. But auto is close to the size of the
cell market and they already had ARM processors in their IP because of
If this group is too quiet for you, how about some posts on *why* the
TMS470 chips are so good? Most of my applications require a low power
device and low power was not a design goal of the TMS470 because of
the target market. So I have not looked as hard at them as other
brands. However, my understanding is that the auto market is starting
to ask for lower power devices because there are so many now appearing
in cars that they are reaching the point where they drain the battery
when the key is off. So they are asking for low power standby modes.
I understand that there is a ultra-programmable timer in the TI ARMs
that is actually a mini-CPU. I can imagine this is very useful for
I have heard that TI is coming out with Cortex-M3 and A8 flavors of
CPUs. I will be very interested in learning more about these.

excellent! The ARM core in the combination with powerful I/O rounded
up with low power consumption is the best what developer can have.
Just from the developer's point of view, device is not much of use
if you need to bang your head for hours in order to figure out how
it works. Mostly because of poor technical documentation.
- I have been working with this part now for just under 2 years. In
general, I have found the TMS470R1B1M to be a great part. The HET is
very powerful (but difficult to program). You can do a lot with this
chip without having to jump through hoops (Microchip). It just works.
As for support; I had problems with the memory security module and the
IAR toolset. A real live engineer from TI helped me through it, and
even sent me some sample parts when he realized I had bricked my
development board! Way to go TI!
My biggest issue is the documentation. There is so much of it for this
part and the way it reads makes it difficult to follow. The example
code and app notes help out though.
