The RP235x is an upgrade in many ways: (Just to list a few.)
- Cortex-M33 ISA
- 150MHz
- Trustzone
- AMP and RISC-V Support/Tinkering
- 512KB of RAM
- Improved XIP
- More GPIO and PIO
- Working ADC?
- Actual concurrency support
- Floating point coprocessors
- Improved boot loader comms
- Some security coprocessors
- Reworked parts of DMA and PIO
- Eight Interrupt priorities?
- SIO Doorbells
- Memory architecture performance could be lower.
- Encryption is vulnerable to signature exploits from updates.
- Little benefit in clocking and power management.
- Bus management still weak/weaker.
- Little Endian Registers?
