17. FLASH Memory
The MB91FV130 / MB91F133A have a 254-KB (2 Mbit) capacity and feature a FLASH memory that can write
each half-word (16 bits) using the FR-CPU, delete individual sectors sector and delete groups of sectors together
using a single 3-V power source.
Outline of FLASH Memory
This is a built-in 3-V 254-KB FLASH memory. This FLASH memory is the same as our 2-Mbit (256 K
× 8 / 128
K
× 16) FLASH memory MBM29LV400C and writing is possible from outside the device using a ROM writer. If
used as a built-in ROM of the FR-CPU, as well as having an equivalent function to the MBM29LV400C, instruc-
tions
/ data can be read per word (32 bits) and high-speed operation of the device can be realized.
Refer to the MBM29LV400C data sheet as well as this manual.
The following functions can be realised in MB91FV130 / MB91F133A by combining the FLASH memory macro
and FR-CPU interface circuits.
Functioning as memory for CPU program
/ data storage
Access is possible with 32-bit bus width when used as ROM
Reading
/ writing and erasing (automatic program algorithm *) are possible using CPU
MBM29LV400C-equivalent function of single FLASH memory products
Reading
/ writing and erasing (automatic program algorithm *) are possible using ROM writer
A case where this FLASH memory is used from FR-CPU is described in this section.
Refer to the ROM writer manual separately for details if this FLASH memory is used from ROM writer.
