Memory Organization
The C505 CPU manipulates operands in the following four address spaces:
– On-chip program memory :16K byte ROM (C505(C)(A)-2R) or
32K byte ROM (C505A-4R/C505CA-4R) or
32K byte OTP (C505A-4E/C505CA-4E)
– Totally up to 64K byte internal/external program memory
– up to 64 Kbyte of external data memory
– 256 bytes of internal data memory
– Internal XRAM data memory :256 byte (C505/C505C)
1K byte (C505A/C505CA)
– a 128 byte special function register area
Figure 5 illustrates the memory address spaces of the C505 versions.
