M27C400
Table 7. Read Mode DC Characteristics (1)
(TA = 0 to 70 °C or –40 to 85 °C; VCC = 5V ± 5% or 5V ± 10%; VPP = VCC)
Note: 1. VCC must be applied simultaneously with or before VPP and removed simultaneously or after VPP.
2. Maximum DC voltage on Output is VCC +0.5V.

System Considerations
The power switching characteristics of Advanced
CMOS EPROMs require careful decoupling of the
supplies to the devices. The supply current ICC
has three segments of importance to the system
designer: the standby current, the active current
and the transient peaks that are produced by the
falling and rising edges of E. The magnitude of the
transient current peaks is dependent on the ca-
pacitive and inductive loading of the device out-
puts. The associated transient voltage peaks can
be suppressed by complying with the two line out-
put control and by properly selected decoupling
capacitors. It is recommended that a 0.1µF ceram-
ic capacitor is used on every device between VCC
and VSS. This should be a high frequency type of
low inherent inductance and should be placed as
close as possible to the device. In addition, a
4.7µF electrolytic capacitor should be used be-
tween VCC and VSS for every eight devices. This
capacitor should be mounted near the power sup-
ply connection point. The purpose of this capacitor
is to overcome the voltage drop caused by the in-
ductive effects of PCB traces.
Programming
When delivered (and after each erasure for UV
EPROM), all bits of the M27C400 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 exposition to ultravio-
let light (UVEPROM). The M27C400 is in the pro-
gramming mode when VPP input is at 12.5V, G is
at VIH and E is pulsed to VIL. The data to be pro-
grammed is applied to 16 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.
