It is ROHS3 compliant. For dual-sourcing or a pin-compatible backup, the PSoC 6 CY8C6137BZI-F54 runs a Cortex-M4 at 150 MHz and shares the same 120-LQFP footprint, but check the peripheral set — the PSoC 6 trades the EBI/EMI bus for CapSense and a different ADC architecture. The XMC4200 from Infineon's XMC4000 family is another Cortex-M4 alternative at 80 MHz with CAN-FD, but its 35 I/Os limit parallel-bus applications.

What are the equivalents for CY9BF314RPMC-G-JNE2?
A close functional equivalent in the same package footprint is the PSoC 6 CY8C6137BZI-F54 (Cortex-M4, 150 MHz, 104 I/O) but with a different ADC and no EBI/EMI bus. The XMC4200F64F256BAXQMA1 (Cortex-M4, 80 MHz) is another Infineon alternative but has only 35 I/O.
