Memory Structure The SM59128 has the general 8052 hardware core integration of expanded 768 bytes data RAM and 128K bytes flash. The 128K bytes on-chip flash is divided in two 64K bytes program memory space. 1.1 Program Memory The SM59128 has two 64K bytes on-chip flash memory space as general program memory denoted by bank0 and bank1. Both bank0 and bank1 have up to 4K bytes specific ISP service program memory space. The address range of the 128K bytes is from $0000H to $1FFFFH, the total available ISP service program space is from $F000H to $FFFFH in bank0 and $1F000H to $1FFFFH in bank1. The ISP service program size can be partitioned to N blocks of 512 bytes (N=0 to 8). When N=0 means no ISP service program space is available, total 128K bytes flash memory space is for main program. When N=1 means memory address $FE00H to $FFFFH and $1FE00H to $1FFFFH are reserved for ISP service program. When N=2 means memory address $FC00H to $FFFFH and $1FC00H to $1FFFFH are reserved for ISP service program...etc. User is able to select and program the number of N by writer. The feature of FLASH memory is shown as following: READ: byte-wise WRITE: byte-wise within 30us (previously erased by a chip erase). ERASE: Full Erase (64K bytes) within 2 sec. Erased bytes contain FFH Endurance : 100K erase and write cycles each byte at TA=25℃ Retention : 10 years 1.1.1 Program Code Security MOVC instruction executed from external program memory space will not be able to fetch internal codes from on-chip program memory space when the chip is protected. |
