5.6 External Memory Interface
CY8C34 provides an External Memory Interface (EMIF) for
connecting to external memory devices. The connection allows
read and write accesses to external memories. The EMIF
operates in conjunction with UDBs, I/O ports, and other
hardware to generate external memory address and control
signals. At 33 MHz, each memory access cycle takes four bus
clock cycles.

5.7 Memory Map
The CY8C34 8051 memory map is very similar to the MCS-51
memory map.
5.7.1 Code Space
The CY8C34 8051 code space is 64 KB. Only main flash exists
in this space. See the
“Flash Program Memory”
page 21.
Document Number: 001-53304 Rev. *K
Figure 5-1
is the EMIF block diagram. The EMIF supports
synchronous and asynchronous memories. The CY8C34
supports only one type of external memory device at a time.
External memory can be accessed via the 8051 xdata space; up
to 24 address bits can be used. See
page 25. The memory can be 8 or 16 bits wide.

5.7.2 Internal Data Space
The CY8C34 8051 internal data space is 384 bytes, compressed
within a 256-byte space. This space consists of 256 bytes of
RAM (in addition to the SRAM mentioned in
21) and a 128-byte space for Special Function Registers (SFRs).
See
Figure
5-2. The lowest 32 bytes are used for 4 banks of
registers R0-R7. The next 16 bytes are bit-addressable.
