Programming/reading

In PROM mode, operation is the same as that of the M5M27C101K, but programming conditions of

PROM programmer are not set automatically because there are no internal device ID codes.

Accurately set the following conditions for data programming/reading. Take care not to apply 21 V

to the VPP pin (is also used as port P47), or the product may be permanently damaged.

Programming voltage: 12.5 V

Setting of PROM programmer address: Refer to “Table 3.3.2”

Erasing

Contents of the windowed EPROM are erased through an ultraviolet light source with the wavelength

2537 Angstrom. At least 15 W•sec/cm2 are required to erase EPROM contents.
