Figure 6. Programming and Verify Modes AC Waveforms
The associated transient voltage peaks can be
suppressed by complying with the two line output
control and by properly selected decoupling ca-
pacitors. It is recommended that a 0.1
F ceramic
capacitor be used on every device between VCC
and VSS. This should be a high frequency capacitor
of low inherent inductance and should be placed
as close to the device as possible. In addition, a
4.7
F bulk electrolytic capacitor should be used
between Vcc and VSS for every eight devices. The
bulk capacitor should be located near the power
supply connection point. The purpose of the bulk
capacitor is to overcome the voltage drop caused
by the inductive effects of PCB traces.
Programming
When delivered (and after each ’1’s erasure for UV
EPROM), all bits of the M27C1024 are in the ’1’
state. Data is introduced by selectively program-
ming ’0’s into the desired bit locations. Although
only ’0’s will be programmed, both ’1’s and ’0’s can
be present in the data word. The only way to
change a ’0’ to a ’1’ is by die exposure to ultraviolet
light (UV EPROM). The M27C1024 is in the pro-
gramming mode when VPP input is at 12.75V, E is
at VIL and P is pulsed to VIL. The data to be
programmed is applied to 16 bits in parallel to the
data output pins. The levels required for the ad-
dress and data inputs are TTL. VCC is specified to
be 6.25V
± 0.25V.
PRESTO II Programming Algorithm
PRESTO II Programming Algorithm allows pro-
gramming of the whole array with a guaranteed
margin, in a typical time of 6.5 seconds. Program-
ming with PRESTO II consists of applying a se-
quenceof 100
s programpulses toeach worduntil
a correct verify occurs (see Figure 7). During pro-
gramming and verify operation, a MARGIN MODE
circuit is automaticallyactivated in order to guaran-
tee that each cell is programmed with enough
margin. No overprogram pulse is applied since the
verify in MARGIN MODE provides necessary mar-
gin to each programmed cell.
