Thank you for the questions!
1) No, not yet. Currently, the PSoC 62 and 63 are sample-able, specifically CY8C6247BZI-D54 and the CY6347BZI-BL53. These parts will be in production by end of Q1, early Q2. The PSoC 60 and 61 will be available in mid Q2.
2) Please see reply to #1.
3) Yes, by the mid Q2 timeframe.
4) This is a issue with the datasheet and will be corrected. Please use the Creator device selector.
Let me know if you have any other questions, thank you!
