C8051F300/1/2/3/4/5
1.2.
The CIP-51 has a standard 8051 program and data address configuration. It includes 256 bytes of data RAM, with the
upper 128 bytes dual-mapped. Indirect addressing accesses the upper 128 bytes of general purpose RAM, and direct
addressing accesses the 128 byte SFR address space. The lower 128 bytes of RAM are accessible via direct and indi-
rect addressing. The first 32 bytes are addressable as four banks of general purpose registers, and the next 16 bytes
can be byte addressable or bit addressable.
The C8051F300/1/2/3 includes 8k bytes of FLASH program memory (the C8051F304 includes 4k bytes; the
C8051F305 includes 2k bytes). This memory may be reprogrammed in-system in 512 byte sectors, and requires no
special off-chip programming voltage. See Figure 1.5 for the C8051F300/1/2/3 system memory map.
