12.0 V. Applied voltages in excess of the rating can permanently damage the device. Insure, in
particular, that peak overshoot at the Vpp and MD2 pins does not exceed the maximum rating of
13 V. Also, be very careful about PROM programmer overshoot.
(2) Before programming, check that the chip is correctly mounted in the PROM
programmer. Overcurrent damage to the device can result if the index marks on the PROM
programmer socket, socket adapter, and chip are not correctly aligned.
(3) Don’t touch the socket adapter or chip while programming. Touching either of these can
cause contact faults and write errors.
(4) Precautions in turning the programming voltage (V

These power-on and power-off timing requirements should also be satisfied in the event of a
power failure and recovery from a power failure. If these requirements are not satisfied, the
flash memory may not only be unintentionally programmed or erased; it may be permanently
damaged.
