'[PIC]: Single chip USB solution'

There have been some threads where people beat up the current Microchip chips

but...............................

a quick web search didn't show any other micro/USB combos in convenient DIP or SOIC packages.

The combo offerings from Cypress and Atmel are huge chips if you need very little I/O.

Doesn't look like FTDI offers a USB chip with micro. That right?

Any suggestions for easy to work with, low pin count USB/micro chips?

thanks

chuckc

I got this from Microchip last week:

[QUOTE] 

The new PIC18F USB devices are full-speed USB devices. The part numbers are

PIC18F2455/2550/4455/4550. The advanced datasheet for these is available now

on the Microchip website in the datasheet section. 

http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1434

They are due for release to production end of October and sampling is due

end of November. 

Best Regards,

Thanks for the inside poop.

They added them to MPLAB a couple weeks ago and I've been waiting for the  news release.

Now do I want that first rev silicon?  Hmmmmmm.   :-)

    How fast must your USB connection be?

    Although Cypress's full-speed (12 Mbit/sec) and high-speed (480

    Mbit/sec) USB micros come in nothing smaller than 56-pin SSOP,

    the low-speed (1.5 Mbit/sec) parts are available in 16- and

    18-pin DIP packages.

    Yes, that's right.

16 or 18 pins is perfect but I missed them on the Cypress page.

Any suggestions on part numbers to look at?

I'm looking to build something to speak HID, sending a few bytes every minute.

    CY7C63221A/31A (16- and 18-pin) or CY7C63723/43 (18- and 24-pin).

Oh, one more thing, Charles...

If you haven't already, you may want to take a look at Jan Axelson's 

book, "USB Complete".  It includes HID designs using the Cypress 

parts I listed.

And is Cypress ever like to so one of their small USB parts with

flash memory?

Hi Charles.

AT43xxx has USB onboard ( http://www.atmel.com for answers )
