0607F–EPROM–12/07

AT27LV512A

Notes:

2. This parameter is only sampled and is not 100% tested. Output Float is defined as the point where data is no longer driven –

see timing diagram.

3. Program Pulse width tolerance is 100 µsec

± 5%.

Note:

1. The AT27LV512A has the same Product Identification Code as the AT27C512R. Both are programming compatible.
