ISM43362-M3G-L44 RAM 128KB FLASH 1MB We recommend the ISM4343-WBM-L54C as a replacement for the ISM43362-M3G-L44

ISM4343-WBM-L54 RAM 256KB FLASH 1MB plus additional SPI FLASH 2MB

ISM43340-WBM-L44-10 RAM 128KB+64KB (Core Coupled Memory) FLASH 1MB plus Optional SPI FLASH 2MB (Note – SPI FLASH is not available when using SPI Host interface)
