13. FLASH Memory
The MB91F158 contains a 510-Kbyte (4 Mbits) flash memory. The sectors can be erased all at once or sector
by sector and that can be written with the FR-CPU by half word (16 bits) using a single 3 V power supply.
The MB91F158 accomplishes the following functions by a combination of the flash memory macro and the FR-
CPU interface circuit :
Functions as the CPU program/data storage memory :
When used as a ROM, the memory is accessible with a 32-bit bus width.
Allows the CPU to read read/write/erase the memory (automatic program algorithm*) .
Functions equivalent to the stand-alone MBM29LV400C flash memory product :
Allows a ROM programmer to read from/write to/erase the memory (automatic program algorithm*)
At this time, using the flash memory from the FR-CPU is described. For detailed information about using the
flash memory from the ROM programmer, refer to the ROM programmer instruction manual.
