Hi,
Why two nos. of crystals(one is 32Khz and another is 24Mhz) are required in CY8C-142 Module KIT.
If both are required for BLE feature or without these two BLE feature may be used?
regards
AMIT

The 24MHz crystal is for the BLE radio, CPU and peripherals and is absolutely required, while the 32KHz is for maintaining a stable low-speed clock which might not be required, but must be accounted for when deep-sleep power saving states are used to wake up the chip at a precise rate.

Thanks Bob, it means to use BLE feature of PSoC4 we need to use 24MHz external crystal or TCXO.
