We are looking to upgrade our wearable product from PSoC 4 BLE to the PSoC 6 BLE however according to the datasheet there is only a massive 124-ball BGA package and a likewise large QFN. Is there no 76-ball CSP like there was with the PSoC 4 BLE?
We don't have plans for a 76 CSP for PSoC 6 BLE (PSoC 63 lineup), but we have 2 package options, a 116-BGA (5.2 x 6.4 x 0.5 mm, 0.5mm pitch) and 104-CSP (3.8 x 5 x 0.65 mm, 0.35mm pitch). Please take a look at the PSoC 63 Datasheet.
Let me know if you have other questions.
