Electric Characteristic Differences Among
Mask ROM, Flash Memory, and One Time
PROM Version MCUs
There are differences in electric characteristics, operation margin,
noise immunity, and noise radiation among mask ROM, flash
memory, and One Time PROM version MCUs due to the differ-
ences in the manufacturing processes.
When manufacturing an application system with the flash memory,
One Time PROM version and then switching to use of the mask
ROM version, perform sufficient evaluations for the commercial
samples of the mask ROM version.

ROM PROGRAMMING METHOD
The built-in PROM of the blank One Time PROM version and built-
in EPROM version can be read or programmed with a
general-purpose PROM programmer using a special programming
adapter. Set the address of PROM programmer in the user ROM
area.
Table 20 Programming adapter
The PROM of the blank One Time PROM version is not tested or
screened in the assembly process and following processes. To en-
sure proper operation after programming, the procedure shown in
Figure 77 is recommended to verify programming.
