Atmel’s innovative desi gn techniques provide fast sp eeds
that rival 5V parts while keepi ng the lo w power con sump­tion of a 3.3V supply. At V

= 3.0V, any byte c an be

CC

accessed in less than 70 ns. With a typical power dissipa­tion of only 18 mW at 5 MHz and V

= 3.3V, the

CC

AT27LV010A consumes less than one fifth the power of a
standard 5V EPROM. Stan dby mod e su ppl y c urre nt is typ i­cally less than 1 µA at 3.3V.

The AT27LV010A is availa ble in in dus try stan dard J EDE C­approved one-time progr am ma ble (OTP ) pl astic P LCC an d
TSOP packages. Al l devic es featur e two-lin e contro l (CE

) to give designers the flexibility to prevent bus

OE
contention.

The AT27LV010A operating with V

at 3.0V produces TTL

CC

level outputs that are compatible with standard TTL logic
devices operating at V

= 5.0V. The device is also capa-

CC

ble 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 AT27LV010A has additional features to ensure
high quality and eff icie nt produc tion use. Th e Rapid™ Pro­gramming Algorithm reduces the time required to program
the part and guarantees reliable programming. Program­ming time is typically only 100 µs/byte. The Inte grated

Product Identific ation Code electr onically identifi es the
device and manufacturer. This feature is used by i ndustry
standard programming equipment to sele ct the prope r pro­gramming algori thms an d voltag es. The AT 27LV01 0A pro­grams exactly the same way as a standard 5V AT27C010
and uses the same programming equipment.

System Considerations

Switching between active and standby conditions via the
Chip Enable pin may produ ce tra ns ien t vo ltag e ex cu rs i ons .

,

Unless accommodated by the system design, these tran­sients may exceed data sheet limits, resulting in device
non-conforman ce. At a mini mum, a 0.1 µF high frequency,
low inherent inductance, ceramic capacitor should be uti­lized for each device. This capacitor should be connected
between the V
close to the device as possible. Additionally, to stabilize the
supply voltage level on printed circuit boards with large
EPROM arrays, a 4.7 µF bulk electrolytic capacitor should
be utilized, again connected between the V
terminals. This capacitor should be positioned as close as
possible to the point where the power supply is connected
to the array.
