Texas Instruments has announced a new family in its MSP430 ultra-low power
16-bit RISC microcontroller product line that provides twice the processing
performance (16 RISC MIPS) and half the stand-by power consumption compared
to earlier devices.

MSP430F1101 [Sept 1999, revised 2003 ] States
Ultralow-Power Consumption
- Active Mode: 160 ľA at 1 MHz, 2.2 V
- Standby Mode: 0.7 ľA
- Off Mode (RAM Retention): 0.1 ľA

MSP430F2101 family Data, Sept 2004 States
Ultralow-Power Consumption
- Active Mode: 200 ľA at 1 MHz, 2.2 V
- Standby Mode: 0.7 ľA
- Off Mode (RAM Retention): 0.1 ľA

Seems their own data sheets directly contradict this press release ?

 From this, the operate power has actually got WORSE ?!

Yes, they carefully word the claim 'stand-by', but last time
I checked 0.7uA was not HALF of 0.7uA :)

Perhaps the errata is still comming ?

compared

The current consumption at 3V in LPM3 decreased to about one half.
That's what really counts in battery operated systems.

The internal comparator still consumes too much power. Microchip leads in
this important issue, since they introduced the ultra low power wake up
module which consumes only 100-300nA.
In solar cell based designs LPM3 still consumes too much energy.

  Hmmm, yes, right down in the fine print, and only for 3V / Room temp.
85'C is less of an improvement, MAX's are still TBF, and 2.2V is
no change.

  That's rather a long way short of a blanket 'half the stand-by power'
claim, esp as there are a number of standby modes....

Still, TI DID add the 'Zero power' BOD, which is a good move.
IMO they should put that in the press release, and leave off the claims
that conflict with their page-ones.....

These are also the low end of the product line.  When they announce the
MSP430F249,  (or something with at least 32KFlash), then I'll pay a bit
more attention.

  Looking some more at TI's 'fine print' I see the Active (Flash ON)
figures for 4096Hz, that are on the F1xx family, have quietly been
dropped on the F2xx series ?!.

  In data sheets it is what they DONT say that's often more important :)

  It is now very hard to compare the F2xx with the C8051F330, which
gives
  32KHz Osc, FLASH On  = 9uA Typ    [ Running Code @ 32KHz ]
  32KHz Osc, FLASH Off = 7.5uA Typ  [ Perihperals active ]

Does anyone have these operating points for the F2xx series ?
