■ PROGRAMMING AND ERASING FLASH MEMORY ON THE MB89F538/F538L
1.
Flash Memory
The flash memory is located between 4000H and FFFFH in the CPU memory map and incorporates a flash
memory interface circuit that allows read access and program access from the CPU to be performed in the same
way as MASK ROM. Programming and erasing flash memory is also performed via the flash memory interface
circuit by executing instructions in the CPU. This enables the flash memory to be updated in place under the
control of the CPU, providing an efficient method of updating program and data.
2.
Flash Memory Features
48 Kbytes
× 8-bit configuration (16 Kbytes + 8 Kbytes + 8 Kbytes + 16 Kbytes sectors)
Automatic programming algorithm (Embedded algorithm : Equivalent to MBM29LV200)
Includes an erase pause and restart function
Data polling and toggle bit for detection of program/erase completion
Detection of program/erase completion via CPU interrupt
Compatible with JEDEC-standard commands
Sector Protection (sectors can be combined in any combination)
No. of program/erase cycles : 10,000 (Min)
3.
Procedure for Programming and Erasing Flash Memory
Programming and reading flash memory cannot be performed at the same time. Accordingly, to program or
erase flash memory, the program must first be copied from flash memory to RAM so that programming can be
performed without program access from flash memory.
4.
Flash Memory Register
Flash memory control status register (FMCS)
5.
Sector Configuration
The table below shows the sector configuration of flash memory and lists the addresses of each sector for both
during CPU access a flash memory programming.
Sector configuration of flash memory
* : Programmer address
The programmer address is the address to be used instead of the CPU address when programming data from
a parallel flash memory programmer. Use the programmer address on programming or erasing using a general-
purpose parallel programmer.
