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 indirect 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 CIP-51 additionally has a 1024 byte RAM block in the external data memory address space. This 1024 byte
block can be addressed over the entire 64k external data memory address range (see Figure 1.5).
The MCU’s program memory consists of 16k + 128 bytes of FLASH. This memory may be reprogrammed in-
system in 512 byte sectors, and requires no special off-chip programming voltage. The 512 bytes from addresses
0x3E00 to 0x3FFF are reserved for factory use. The additional 128 byte block is located at address 0x8000. See
Figure 1.5 for the MCU system memory map.
