I am using the atmel SAM3N00B microcontroller and the only way I can see to do in circuit serial programming is to use the 20 way JTAG connector.
However, this connector is too big for our production unit, and I wondered if there is a smaller, say 5 pin programming connector which I could use?

What is the minimum vcc voltage at which all atmel SAM3N00B microcontroller parts from any production batch can be gauranteed to start up?
Page 696 of the datasheet appears to say that the SAM3N00B may start up at any voltage between 1.62V and 3.6V..-but is it garanteed to start up at 1.62V?

It looks like you have already started with atmel, so stay with it ..
All microcontrollers can do almost the same but the more you practise with a particular type, the more "fluent" you are in it, and the easier for you is to use it in all sorts of applications ..
Here you have a PDF file with practical examples on 89C51/2 UART including explan

I have an atmel microcontroller circuit and it is not working
I probe the XIN/XOUT lead (crystal input) but could not see a 20mhz signal on my scope.. I checked VDD and ground connector and they are good.
Is it a bad chip or is there something else I can check?

Just stick with the 10MBit soloution, the atmel AT91 isn't fast enough to take advandtage of 100MBit. The highest performance of the fastest atmel AT91 is about 70 MIPS. So you don't gain any speed advantage by using 100MBit instead of 10MBit.
You not right, for 100MBit you do not need higer performance than 70 ( really 10-20 M
