Section 6 Memory Modules
Section 6 Memory Modules
This section describes the memory modules.
Products of this series are equipped with code flash memory, data flash
memory, and RAM. Refer to Table 6-1, On-Chip Memory of V850E2/PG4-L
Products for the memory size per product.
Code flash memory is programmable in two ways: by a flash programmer or by
self-programming. Data flash memory is also programmable by a flash
programmer.
If the dedicated flash programmer is to program on-chip memory, it has to be
connected to the target system.
For self-programming, an application program is used instead of the dedicated
flash programmer.
Flash memory is commonly used for the following purposes in the
development environment and field of application:
○
altering software after solder-mounting of the microcontroller on the target
system,
○
differentiating software in the small-scale production of a variety of models,
and
○
adjusting data when mass production starts.
