'[EE]: Interesting micro-controller'

Don't know how long this has been out - it's the latest member of a non-PIC
microcontroller family.

Don't know price but I believe they are all aimed at being low cost
relatively.(as they all claim).

16 bit
60 kB flash (I want one :-) )
2 KB RAM
2 x serial
12 bit 200 ksps A2D with 8 channel mux
16 word A2D input buffer
Hardware multiply, 16 bit.
48 i/o
PLCC & ???
Low battery detect.
Onchip temperature sensor.
Onboard 1.25V and 2.5V references.
Two timers
10 PWM (!) (7 on timer 1, 3 on timer 2)
2 oscillators for eg 32 KHz and 8 MHz or whatever.
250 uA/MIPS
8 MIPS max
1.8v - 3.6v operation.
Watchdog
Antibrownout
Flash writeable in 256 byte blocks from program.
<1uA standby.
6uS wakeup from standby.

$US99 intro development system. Parallel port operation with no external
power.
With debug, assemble, sim, limited C,
Full speed operation with 3 breakpoints.


Who is this masked man ???
See below.
Note I have no shares in the company or pecuniary interest of any sort etc
:-)

There are numerous less capably specced (and cheaper) variants in the
family.

   [mps430f149 specs and pointer.]

It's not "out."  It's "preliminary" specs.  Supposed to ship in volume
Q4 2000 (ie soon, but I don't even see them offering samples yet.)

64pin QFP (sigh.)  I Wonder why TI is avoiding the 40pin DIP package for
these processors?


   Don't know price but I believe they are all aimed at being low cost

Elsewhere they claim $6 each for 1000s...

1. Consider the market they are going after. [Scenix, likewise, never
  put their SX48-52s into any package but tiny smt].

2. Ask yourself what is the best way to limit the number of "nuisance"
  calls to your engineering staff - ie, calls from "anyone" at all
  who isn't "experienced" enough to be fielding 10,000 units per
  year.

cheers,

$6 US, och! No where near the cheap side at all! Take a look at some ofthe
Hitachi stuff to come out, now this is what I call cheap!

the price is around $15 for singles

EBV sells MSP430 with 1K Flash for $2,05 and the 2K version for $3,50 in 1
pce quantity! (hello Microchip!)

> 16 bit

I don't know how long will take to program it - last week I ordered my
starter kit and will get it few days. The programming adapter have no need
for external power supply as takes the power from the PC port.
I can have lunch while 16F877 get programmed, but yesterday Microchip had
seminar here and their FAE told me that the new release LIGHT FLASH (made
on 0,5 um technology) will program 4 words at once and the programming time
will be cut 4 times!
Unfortunately the LIGHT FLASH can be programmed only 100 times.

well all PIC micro have it too: WDT is depend on the temperature, so you
can measure the temperature with WDT.

If this is the processor family I'm thinking of, it's been around a few
years.  TI sends me lit  making it sound like the best thing since sliced
bread, but then I find out it's actually a bait-and-switch scheme.  They
bait you with high functionality and dirt-cheap prices.  Then when you
ask, you find out that the dirt-cheap prices are for stripped-down
models, and the full-featured models are expensive.

Still, I agree it's an interesting family, and if I was starting from
scratch, I'd give it a serious look.  They seem to have done a good job
running at really low power.

I'm working with it...it's very good..and the instructions remember the old
