'[EE] New USB OTG AVR MCU from Atmel'
Chen Xiao Fan
Atmel has released AT90USB646/647/1286/1287 AVR MCUs with
USB 2.0 full-speed/low-speed function and USB OTG (USB
on the go) function. This is quite interesting.
>From Atmel's marketing flyer (doc4036.pdf):
"Atmel's family of 8-bit microcontrollers supports a wide range of USB
applications: high-end keyboards, mice, phone accessories, toys, serial
adapters and industrial equipment.
An on-chip bootloader permits very quick firmware download from a PC,
without using a parallel programmer or dedicated hardware.
Nonvolatile memory stores configuration parameters enabling the
system to be instantly operational, even without connection to a PC.
C51 solutions offer 16KB to 64KB of Flash with up to 4 MIPS and USB
AVR® solutions offer 64KB to 128KB of Flash with up to 16 MIPS, USB
function and On-The-Go for dual role host or function."
PS: I do not use the [AVR] tag since it is rarely used.

bah. They'd be more interesting if they weren't 64TQFP "big"
AVRs. But I guess for "real" customers, the size of the package
matters more than the number of pins, and who cares as long as
it fits in the mouse body :-(

I'd like to use DIPs for testing as well. But there are many
chips only available at "not-so-hobbyist-friendly" packages.
Yet there are many hobbyists who make nice use of them. For
example, there are people who make their own PCBs to accomodate
the bigger SMT ICs (smaller SOIC is easy to solder). We can also
buy pre-built PCBs or even demo boards. For example, the LPC2xxx
ARMs seems to have gathered a good followings despite the
fact the packagings are not so easy to handle. Of course I
won't deal with the QFN64 packages with manual soldering.
TQFP64 may be not that difficult with a proper PCB.
PIC24/dsPIC33s and many PIC18F are also with higher pin count
so that no DIP packages are available for them.
