Release for this part will be in mid-Q2 2018. In the meantime, we do have a PSoC 62 line MCU that you can evaluate until the PSoC 61 MCU is released. The PSoC 62 MCU is dual-core and provides more analog/digital features than the PSoC 61, but you can port whatever you've done on a PSoC 62 MCU into a PSoC 61 MCU (keeping in mind that you design your PSoC MCU using the M4 only).
Let me know if you have any other questions!
Thank you for your information.
Accoding to your advice, we'll propose CY8C6247BZI-D54,too.
