Programming Precautions
Program using the specified voltages and timing.
The programming voltage (V
) in PROM mode is 12.5 V.
PP
If the PROM programmer is set to Renesas Technology HN27C101 specifications, V
will be
PP
12.5 V. Applied voltages in excess of the specified values can permanently destroy the MCU.
Be particularly careful about the PROM programmer's overshoot characteristics.
Before programming, check that the MCU is correctly mounted in the PROM programmer.
Overcurrent damage to the MCU can result if the index marks on the PROM programmer,
socket adapter, and MCU are not correctly aligned.
Do not touch the socket adapter or MCU while programming. Touching either of these can
cause contact faults and programming errors.
The MCU cannot be programmed in page programming mode. Select the programming mode
carefully.
The size of the PROM is 128 kbytes. Always set addresses within the range H'00000 to
H'1FFFF. During programming, write H'FF to unused addresses to avoid verification errors.
