What physical type of internal boot ROM is used in the LPC54005JBD100 or LPC54S005JBD100 (and other LPC54xxx)?
Is it mask ROM? Or flash memory with write/erase functions disabled?
Is it possible to load firmware into this microcontrollers from external SPI-MRAM memory (ex. MR25H40)?
(memory located on the SPIFI or on the SPI bus). Or similar memories (FRAM, FeRAM (ex. MB85RS4MT). Insteed of FLASH.
PS: This information is needed to select the appropriate MCU for a new device.
