The memory space of the XC164CM is configured in a “von Neumann” architecture. This
means that code and data are accessed within the same linear address space.
Attached there are two examples for memory mapping of the XC164CM Board.
4.1
The XC164CM incorporates 64 Kbytes of embedded Flash memory (starting at location
C0’0000H) for code or constant data. It is operated from the 5 V pad supply and requires
no additional programming voltage. The Flash array is organized in five sectors of 4 × 8
Kbytes, and 1 × 32 Kbytes1). It combines the advantages of very fast read accesses with
protected but simple writing algorithms for programming and erasing. The 64-bit code
read accesses realize maximum CPU performance by fetching two double word
instructions (or four single word instructions) in a single access cycle.
Data integrity is enhanced by an error correction code enabling dynamic correction
ofsingle bit errors. Additionally, special margin checks are provided to detect and correct
problematic bits before they lead to actual malfunctions.
The On-chip programming can be done either with a utility program, so called “Memtool”
or with several other Toolchains of our Tool vendors. Memtool is using the ASC
bootstrap Loader. The latest version can be found on the Infineon web side. Other tools
are using the OCDS interface.
