smallest DSP package

All-

Does anyone know the smallest DSP or microcontroller package that TI has? The algorithm complexity is not high, some
22 kHz sampling rate, some averaging, and some FFTs.

Hello jeff,

The ancient technology 24x comes in a 32 pin version, but I wouldn't
suggest it.
Piccolo 28x is probably the ticket - min 38 pins.

There might be a 54x or 55x device but TI's "Intergalactic Selection
Guide" does not include a pin count :-).

Smallest total package or just fewest pins?

I'd guess an MSP430 such as the 20-pin such as:
http://focus.ti.com/docs/toolsw/folders/print/msp-fet430u28.html. I
believe those packages are pretty small.

You can even find an MSP430 in a 14-pin DIP:
http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_%28MSP-EXP430G2%29.

You can search the microcontrollers and digital signal controllers at

I haven't done the math, by I would expect the MSP430 *might* be a
little weak on the performance and it may not have enough RAM.

Smallest total package.

I should probably be asking about "lowest total power consumption", as size would likely go hand-in-hand.

The MSP430 line looks promising, the F5xx series may be the leading candidate.
