1.2 Data Memory
The SM5964 has 1K bytes on-chip RAM, 256 bytes of it are the same as general 8052 internal memory structure while the
expanded 768 bytes on-chip RAM can be accessed by external memory addressing method (by instruction MOVX.) or by
bank mapping direct addressing mode.
Extension Function Description
1. Memory Structure
The SM5964 is the general 8052 hardware core to integrate the ISP function module as a single chip microcontroller. Its
memory structure follows general 8052 structure.
1.1 Program Memory
The SM5964 has 64K byte on-chip flash memory which used as general program memory, on which include up to 4K byte
specific ISP service program memory space. The address range for the 64K byte is $0000 to $FFFF. The address range
for the ISP service program is $F000 to $FFFF. The ISP service program size can be partitioned as N blocks of 512 byte
(N=0 to 8). When N=0 means no ISP service program space available, total 64K byte memory used as program memory.
When N=1 means memory address $FE00 to $FFFF reserved for ISP service program. When N=2 means memory
address $FC00 to FFFF reserved for ISP service program,...etc. Value N can be set and programmed into SM5964 by
writer.
