MX27C512 compatible

The MX26C512A is erased by EPROM programmer or in-system. The device is set up in erase mode when A9 =OE/VPP = 12.75V are applied, with VCC = 5V. (Algorithm is shown in Figure 3). The erase time is around 1sec. If the erase is not verified, an additional erase processes will be repeated for a maximum of 200 times.

MODE           !CE !OE/VPP A0 A9 OUTPUTS
Erase VIL VPP 12.75V X VPP 12.75V HIGH Z
Erase Verify VIL VPP 12.75V X X DOUT

VCC = 5V

OE/VPP = 12.5V is applied with VCC = 6.25V
