SM5952E Datasheet, PDF (17/53 Pages) SyncMOS Technologies,Inc – 256 bytes SRAM as standard 8052

SM5952E
8-Bit Micro-controller
8KB with 4KB ISP Flash
& 1KB RAM embedded
3. Memory Structure
The SM5952E memory structure follows general 8052 structure. It is 8KB+4KB program memory.
3.1 Program Memory
The SM5952E has 8KB+4KB on-chip flash memory which can be used as general program memory, on which
include up to 4K byte specific ISP service program memory space. The address range for the 8KB+4KB is $0000h
to $2FFFh. The address range for the ISP service program is $2000h to $2FFFh. 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 8KB+4KB memory used as program memory. When N = 1 means address $2E00h to $2FFFh reserved for
ISP service program. When N=2 means memory address $2C00h to $2FFFh reserved for ISP service
program…etc. Value N can be set and programmed into SM5952E configuration by writer. As shown in Fig. 3-1.
