32170 Group, 32174 Group
Built-in Flash Memory and RAM
32170 and 32174 Group contain Flash Memory and RAM
stated as follows.
The internal flash memory can be programmed on-board
(i.e., while being mounted on the printed circuit board). This
means that the same chip as will be used in mass-produc-
tion can be used directly from the development stage on,
allowing for system development without having to change
the printed circuit board when proceeding from trial produc-
tion to mass-production.

Built-in Virtual-flash Emulation Function
Internal flash memory, which is divided from the first address
in units of 8 Kbyte (L banks), can be replaced in 8 -Kbyte
blocks (H70080 4000-H’0080 5FFF) of the internal RAM.
And also the internal flash memory, which is divided from the
first address in units of 4-Kbyte areas (S banks), can be re-
placed in 4 Kbytes areas.
This function allows parts of the program which are fre-
quently changed during development to be altered or evalu-
ated without having to reset the microcomputer each time.
What’s more, when combined with the realtime debugger,
this function helps to reduce the program evaluation period,
because data in the RAM can be rewritten without requiring
any CPU load.
