This part has no on-chip Flash. Program memory is stored externally — boot from a serial SPI Flash, parallel NOR Flash, or an SD card via the EBI/EMI or SSP interface. The 264 KB SRAM is for code execution and data, not program storage. Factor an external memory device into the BOM and verify the boot-source strapping pins on the 144-LQFP package.
Supply range is 2.2 V to 3.6 V.
The Cortex-M4 core runs at 204 MHz. That is the maximum clock for the main processor; the Cortex-M0 companion core runs at a lower frequency, typically 204 MHz as well but with a simpler pipeline.
The part is ROHS3 Compliant. No REACH, UL, or IEC certifications are listed in the manufacturer's standard documentation for this order code.
