Extension Function Description
1. Memory Structure
The SM59264 is the general 8052 hardware core to integrate the expanded 768 byte data RAM, 64KB flash program mem-
ory with ISP function module and 64KB data flash as a single chip micro controller. Its memory structure follows general 8052
structure plus SM59264 proprietary external RAM structure.
1.1 Program Memory
The SM59264 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 SM59264 by writer.
