Micro controllers with UHF transceivers?

Hello Folks,

After some Google searching and perusing the sites of the usual
contenders I only found one uC family that has serious on-chip RF
transceiver capabilities, the Cypress CYWUSB6953 and its brethren.
rfPICs and others usually only have a transmitter.

Anyhow, the Cypress will only serve 2.45GHz but I need the lower UHF
bands for range reasons. Is anything coming down the pike soon or will
that have to remain a two-chip solution?

How about CC1110F32 from TI.

Thanks, Don! How could I have missed that? I was looking at lots of
CC11xx datasheets today. Five bucks is a bit highish but would work in
this case. I guess the programmers will throw tomatoes when I suggest
that. It's a 8051 core (I love the 8051...)

For some reason TI's server was choking a lot today.

You should consider this part limited lifespan IMHO precisely because
of the 51 core. Remember Chipcon is now owned by TI. I would say if
your design horizon exceeds 3~4 years it would be better not to pick
this part.

What part of the spectrum are you trying to cover; 433MHz? 860-ish?
Quite a few solutions aimed at markets like RKE. For example Atmel
covers certain frequencies from 315 to 915MHz ASK/FSK selectable.
