Standby mode supply current is typically less than 1
μ
A at
3.3V.
The AT27LV256A is available in industry standard
JEDEC-approved one-time programmable (OTP) plastic
PLCC, SOIC and TSOP packages . All devices feature
two-line control (CE, OE) to give designers the flexibility to
prevent bus contention.
The AT27LV256A operating with V
CC
at 3.0V produces
TTL level outputs that are compatible with standard TTL
logic devices operating at V
CC
= 5.0V. The device is also
capable of standard 5-volt operation making it ideally
suited for dual supply range systems or card products that
are pluggable in both 3-volt and 5-volt hosts.
Atmel’s AT27LV256A has additional features to ensure
high quality and efficient production use. The Rapid
Pro-
gramming Algorithm reduces the time required to program
the part and guarantees reliable programming. Program-
ming time is typically only 100
μ
s/byte. The Integrated
Product Identification Code electronically identifies the de-
vice and manufacturer. This feature is used by industry
standard programming equipment to select the proper
programming algorithms and voltages. The AT27LV256A
programs exactly the same way as a standard 5V
AT27C256R and uses the same programming equipment.
Description
(Continued)
Switching between active and standby conditions via the
Chip Enable pin may produce transient voltage excur-
sions. Unless accommodated by the system design, these
transients may exceed data sheet limits, resulting in de-
vice non-conformance. At a minimum, a 0.1
μ
F high fre-
quency, low inherent inductance, ceramic capacitor
should be utilized for each device. This capacitor should
be connected between the V
CC
and Ground terminals of
the device, as close to the device as possible. Additionally,
to stabilize the supply voltage level on printed circuit
boards with large EPROM arrays, a 4.7
μ
F bulk electrolytic
capacitor should be utilized, again connected between the
V
CC
and Ground terminals. This capacitor should be posi-
tioned as close as possible to the point where the power
supply is connected to the array.
