8. Memory
The RA4 MCUs support a 4-GB linear address space ranging from 0000 0000h to FFFF FFFFh that can
contain program, data, and external memory bus. Program and data memory share the address space;
separate buses are used to access each, increasing performance and allowing same-cycle access of
program and data. Contained within the memory map are regions for on-chip RAM, peripheral I/O registers,
program code flash, and data flash.
