Section 22 PROM

The PROM version can be set to PROM mode and programmed with a PROM programmer.

22.1

PROM Mode Setting

The PROM version (HD6472237) suspends its microcomputer functions when placed in PROM

mode, enabling the on-chip PROM to be programmed. This programming can be done with a

PROM programmer set up in the same way as for the HN27C101 (VPP = 12.5 V) EPROM. Use of

a socket adapter to convert from 100 pins to 32 pins enables programming with a commercial

PROM programmer.

Caution is required when selecting the PROM programmer, as this LSI does not support page

mode.

Table 22.1 shows how PROM mode is selected.

Socket Adapter and Memory Map

Programs can be written and verified by attaching a socket adapter to convert from 100 pins to 32

pins to the PROM programmer. Figure 22.1 shows the wiring of the socket adapter, and table 22.2

gives ordering information for the socket adapter. Figure 22.2 shows the memory map in PROM

mode.
