14.3.2 Programming Precautions
• Program with the specified voltages and timing.
The programming voltage (V_PP) in PROM mode is 12.5 V.
Applied voltages in excess of the rated values can permanently destroy the chip. Be
particularly careful about the PROM programmer’s overshoot characteristics.
If the PROM programmer is set to Hitachi HN27C101 specifications, V_PP will be 12.5 V.
• Before programming, check that the chip is correctly mounted in the PROM programmer.
Overcurrent damage to the chip can result if the index marks on the PROM programmer,
socket adapter, and chip are not correctly aligned.
• Don’t touch the socket adapter or chip while programming. Touching either of these can cause
contact faults and write errors.
• Select the programming mode carefully. The chip cannot be programmed in page programming
mode.
• The H8/3032 PROM size is 64 kbytes. Set the address range to H'0000 to H'FFFF. When
programming, assign H'FF data to the unused address area (H'10000 to H'1FFFF).
