Description
The AT27LV010A is a high performance, low power, low voltage 1,048,576-bit onetime programmable read on ly mem ory (O TP EPRO M) organ ized as 12 8K by 8 bi ts. It
requires only one supply in t he range of 3. 0V to 3. 6V in normal r ead mo de oper ation ,
making it ideal for fast, portable systems using battery power.
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.
