PS022006-0207
The ZNEO CPU has a unique architecture with a single, unified 24-bit address space.
It supports up to four memory areas:
•
•
•
•
The 24-bit address space supports up to 16 MB (16,777,216 bytes) of memory. The ZNEO
CPU accesses any two of the above memory areas in parallel. In addition, the ZNEO CPU
supports three different data widths:
•
•
•
The ZNEO CPU accesses memories of different bus width:
•
•
A memory map of the ZNEO is illustrated in
non-volatile memory, internal RAM, and internal I/O memory is illustrated in
page 20. The External memory is placed at addresses which is not occupied by internal
memory.
Internal non-volatile memory (Flash, EEPROM, EPROM, or ROM).
Internal RAM.
Internal I/O memory (internal peripherals).
External memory (and/or memory-mapped peripherals).
