7512 Group
Table 13 Summary of the 7512 Group (flash memory version)
FLASH MEMORY MODE
The 7512 Group (flash memory version) has flash memory that
can be rewritten with a single power source.
For this flash memory, two flash memory modes are available in
which to read, program, and erase: the parallel I/O mode in which
the flash memory can be manipulated using a programmer and
the CPU rewrite mode in which the flash memory can be manipu-
lated by the Central Processing Unit (CPU).
Summary
Table 13 lists the summary of the 7512 Group (flash memory ver-
sion).
The flash memory of the 7512 Group is divided into 4 blocks of
User ROM area and Boot ROM area as shown in Figure 68.
In addition to the ordinary User ROM area to store the MCU op-
eration control program, the flash memory has a Boot ROM area
that is used to store a control program in a Boot mode. The user
can write a rewrite control program in this Boot ROM area that
suits the user’s application system. This Boot ROM area can be
rewritten in only parallel I/O mode.
