The M30245FC contains flash memory that can be rewritten with a single voltage of 3.3 V. Three flash
memory modes are available to read, program, and erase:
• CPU rewrite mode in which the flash memory can be manipulated by the Central Processing Unit (CPU).
• Parallel I/O and standard serial I/O modes can be manipulated using a programmer
The flash memory is divided into several blocks as shown in Figure 1.149.
Memory can be erased one block at a time. Each block has a lock bit to enable or disable execution of an
erase or program operation. This allows data in each block to be protected. Table 1.67 shows an overview of
the M30245 (flash memory version).
In addition to the ordinary user ROM area that stores the microcomputer operation program, the flash memory
has a boot ROM area that stores a program to control rewriting in CPU rewrite and standard serial I/O modes.
The boot ROM area has a standard serial I/O mode control program stored in it when it is shipped from the
factory. However, the user can write a CPU rewrite control program in this area specific to the user's applica-
tion system. The boot ROM area can only be rewritten in parallel I/O mode.
