Flash memory size The RP2040 auto-detects its flash memory size on powerup (assuming you are using an IC that supports the method it uses). Max flash size: 16MB (128Mbit) Using flash memory for data storage The entire memory is readable and writable from code. Your program is stored from address 0x00000000. The free area after […]

Code security and RAM security Typically a microcontroller allows the code it runs to be protected against reading and has programming time options to disable debugging. The RP2040 doesn’t have this, it is unable to protect the code it runs or its RAM. The MCU can execute code either from RAM or directly from flash. […]

GPIO pins VDDIO Voltage range 1.8V to 3.3V Diodes to VDDIO ADC GPIO pins have diode to VDDIO, but other GPIO pins do not.
