3. Memory Structure
The SM59R02G1 memory structure follows general 8052 structure. It is 8KB program memory.
3.1. Program Memory
The SM59R02G1 has 8KB on-chip flash memory which can be used as general program memory or EEPROM, on which
include up to 1K byte specific ISP service program memory space. The address range for the 8K byte is $0000 to $1FFF.
The address range for the ISP service program is $1C00 to $1FFF. The ISP service program size can be partitioned as N
blocks of 256 byte (N=0 to 4). When N=0 means no ISP service program space available, total 8K byte memory used as
program memory. When N=1 means address $1F00 to $1FFF reserved for ISP service program. When N=2 means
memory address $1E00 to $1FFF reserved for ISP service program…etc. Value N can be set and programmed into
SM59R02G1 information block by writer. It can be used to record any data as EEPROM. The procedure of this EEPROM
application function is described in the section 13 on internal ISP.
