Some other possibilities -
1) Call your local sales rep or Cypress sales office to see if they can get get some.
2) File a CASE and ask for some samples.

i did that today. their sample stock comes from the same thailand(?) pool, none in USA. no real results. the azi parts that showed Qty 3,619 yesterday now show 0. i, sincerely, think that IT was putting up new product and listed qty that did not exist.
p.s. to post i have to be registered. "You have to be ..." is a little redundant.
Looks like a 4247azi-m485 will drop in with just one ground wire tacked to an unused pin. Mouser has them and i can red label qty 5 for friday delivery.
