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

memory 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.

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 after the chip is protected on the Writer.

Specifications subject to change without notice contact your sales representatives for the most recent information.
