As a result the M27V405 can be programmed as the M27C405 on the same pro- gramming equipments applying 12.75V on VPP and 6.25V on VCC by the use of the same PRES- TO II algorithm. When delivered, all bits of the M27V405 are in the ’1’ state.Data is introduced by selectively programming ’0’s into the desired bit lo- cations. Although only ’0’s will be programmed, both ’1’s and ’0’s can be present in the data word. The M27V405 is in the programming mode when VPP input is at 12.75V, G is at VIH and E is pulsed to VIL. The data to be programmed is applied to 8 bits in parallel to the data output pins. The levels required for the address and data inputs are TTL. VCC is specified to be 6.25V±0.25V, but it can be set to lower values in case of On-Board Program- ming (see dedicated paragraph). |
