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.
