MB90335 Series
63
19. 512 Kbits flash memory
The description that follows applies to the flash memory built in the MB90F337; it is not applicable to evaluation
ROM or masked ROM.
The method of data write/erase to flash memory is following three types.
Parallel writer
Serial dedicated writer
Write/erase by executing program
Description of 512 Kbits flash memory
512 Kbits flash memory is located in FFH bank in the CPU memory map. Function of flash memory interface
circuit enables read and program access from CPU.
Write/erase to flash interface is executed by instruction from CPU via flash memory interface, so rewrite of
program and data is carried on in the mounting state effectively.
Data can be reprogrammed not only by program execution in existing RAM but by program execution in flash
memory by dual operation. Also, erase/write and read in the different bank (Upper Bank/Lower Bank) is executed
simultaneously.
Features of 512 Kbits flash memory
Sector configuration : 64 Kwords × 8 bits/32 words × 16 bits (4 K × 4 + 16 K × 2 + 4 K × 4)
Simultaneous execution of erase/write and read by 2-bank configuration
Automatic program algorithm (Embedded AlgorithmTM*)
Built-in deletion pause/deletion resume function
Detection of programming/erasure completion using data polling and the toggle bit
At least 10000 times guaranteed
Minimum flash read cycle time : 2 machine cycles
* : Embedded AlgorithmTM is a trade mark of Advanced Micro Devices Inc.
Note : The read function of manufacture code and device code is not including.
Also, these code is not accessed by the command.
Flash write/erase
Flash memory can not execute write/erase and read by the same bank simultaneously.
Data can be programmed/deleted into and erased from flash memory by executing either the program
residing in the flash memory or the one copied to RAM from the flash memory.
