8-1-2 Cautions on Use
EPROM Versions differs from the MN101C11* in some of its electrical
characteristics. The user should be aware of these differences.
(1) To prevent data from being erased by ultraviolet light after a program is
written, affix seals impermeable to UV rays to the glass sections at the
top and side sections of the CPU.
(PX-AP101C11-SDC, PX-AP101C11-FBC)
(2) Due to device characteristics of the MN101CP11XXX, a writing test
cannot be performed on all bits. Therefore, storage of the written data
cannot be guaranteed in some cases.
(3) When a program is written, verify that Vc power supply(6V) is connected
before applying the Vpp power supply(12.5V). Disconnect the Vpp
supply before disconnecting the Vcc supply.
(4) Vpp should never exceed 13.5V including overshoot.
(5) If a device is removed while a Vpp of +12.5V is applied, device reliability
may be damaged.
(6) At CE=VIL, do not change Vpp from VIL to +12.5V or from +12.5V to
VIL.
(7) From the time after a program is written until just before mounting,
storage at a high temperature is recommended.
