We have begun shipping three new ZX devices: ZX-32n, ZX-32l, and ZX-328l, all of which are native mode devices.

The first two are based on the 32-pin TQFP packaged ATmega328P while the third is a 28-pin DIP package. The ZX-32l and ZX-328l are low voltage versions that are specified to run with a supply voltage as low as 2.75 volts. The tradeoff is that they run at 7.37MHz, half the speed of most other ZX devices. Other than those differences, the low voltage versions are identical to their "n" suffix counterparts.

In comparison to the ZX-328 series devices, the ZX-32 series devices offer a smaller surface-mount footprint and two additional analog-only inputs.

Do we merely download/use the native mode compiler and specify this new low cost chip as the target?

What's a good source for the 7.3728MHz crystal?

Steve,

I cannot resist Smile The answer to the first question is Yes. The answer to the second question is the same place as you get 14.7456 MHz crystals.

How about offering a 14.7456MHz version of the P-DIP product, specified to run at 5V?


Suggestion: product part number change from "l" (ell) suffix to "nl" to distinguish from possible virtual mode low power product

ZX-328n Native mode PDIP 5V
ZX-328nl Native mode PDIP low power

Or from your BX-24s.

I'm not sure what you're referring to here. Except for a few special OEM devices that operate at 18.432MHz, all of the other devices operate at 14.7456MHz with a supply voltage of 4.5 to 5.5 volts. This includes the ZX-328n which is based on the DIP-28 version of the mega328P.

Some examples:
Digi-Key p/n 300-8481-ND
Digi-Key p/n 631-1098-ND

I confused both of us because, above, the ZX328n isn't referenced - as it's not new! So I discovered by belatedly looking a the product suite on the main page. Sorry.
