Well.. we were just looking at Heisener for a Cypress chip, but can't decide whether to pull the trigger. Have you placed an order and received the product from them?
Yes, we successfully purchased a small quantity of Kinetis microcontrollers which were supposedly tested prior to shipping, those are going into assemblies right now so we'll see if they actually work.
Heisener is just a middleman so every transaction is different unfortunately.
