HD64F3437TF16 Datasheet, PDF (447/752 Pages) Hitachi Semiconductor – 12 V must not be applied to the S-mask model (single-power-supply specification), as this may permanently damage the device.

19.6 Flash Memory Writer Mode (H8/3434F)
19.6.1 Writer Mode Setting
The on-chip flash memory of the H8/3434F can be programmed and erased not only in the on-
board programming modes but also in writer mode, using a PROM programmer.
19.6.2 Socket Adapter and Memory Map
Programs can be written and verified by attaching a special 100-pin/32-pin socket adapter to the
PROM programmer. Table 19.12 gives ordering information for the socket adapter. Figure 19.13
shows a memory map in writer mode. Figure 19.14 shows the socket adapter pin interconnections.
