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 in the C8051F005/06/07/15/16/17 MCUs additionally has a 2048 byte RAM block in the external data
memory address space. This 2048 byte block can be addressed over the entire 64k external data memory address
range (see Figure 1.6).
The MCU’s program memory consists of 32k + 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
0x7E00 to 0x7FFF are reserved for factory use. There is also a single 128-byte sector at address 0x8000 to 0x807F,
which may be useful as a small table for software constants or as additional program space. See Figure 1.6 for the
MCU system memory map.
