C517A
Memory Organization
The C517A CPU manipulates operands in the following five address spaces:
– up to 64 Kbyte of program memory (32K on-chip program memory for C517A-4R)
– up to 64 Kbyte of external data memory
– 256 bytes of internal data memory
– 2K bytes of internal XRAM data memory
– a 128 byte special function register area
Figure 6 illustrates the memory address spaces of the C517A.
