Discussion specific to the DIP and TQFP packaged ZX devices like the ZX-40, ZX-44, ZX-32 and ZX-328 series. The differences between these devices is primarily the packaging and pinout so most issues will apply to all devices.
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.

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.

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.
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.
