Description (Continued)
EPROM. Standby mode supply current is typically less
than 1 A at 3V. The AT27BV010 simplifies system design
and stretches battery lifetime even further by eliminating
the need for power supply regulation.
The AT27BV010 is available in industry standard JEDEC-
approved one-time programmable (OTP) plastic PLCC
and TSOP packages. All devices feature two-line control
(CE, OE) to give designers the flexibility to prevent bus
contention.
The AT27BV010 operating with V
level outputs that are compatible with standard TTL logic
devices operating at V
is compatible with JEDEC approved low voltage battery
operation (LVBO) interface specifications. 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 AT27BV010 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 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 AT27BV010
programs exactly the same way as a standard 5V
AT27C010 and uses the same programming equipment.

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 F high fre-
quency, low inherent inductance, ceramic capacitor
should be utilized for each device. This capacitor should
be connected between the V
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 F bulk electrolytic
capacitor should be utilized, again connected between the
V
tioned as close as possible to the point where the power
supply is connected to the array.
