Description

The AT27BV010 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 2. 7V to 3. 6V in normal r ead mo de oper ation ,
making it ideal for fast, portable systems using either regulated or unregulated battery
power.

AT27BV010

Rev. 0344F–10/98

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 3V supply. At V

= 2.7V, any byte can be

CC

accessed in less than 90 ns. With a typical power draw of
only 18 mW at 5 MHz an d V

= 3V, the AT27B V010 con-

CC

sumes less than one fift h the power of a standard 5V
EPROM. Standby mo de supply curr ent is typically le ss
than 1 µA at 3V. The AT27BV 010 si mplifies system desig n
and stretches battery lifetime even further by eliminating
the need for power supply regulation.

The AT27BV010 is available in industry standard JEDEC­approved one-time programmable (OTP) plastic PLCC,
TSOP, and VSOP packages. All devices feature two-line
control (CE

, OE) to give designers the flexibility to prevent

bus contention.
The AT27BV010 op eratin g with V

at 3.0V produces TTL

CC

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

= 5.0V. At VCC = 2.7V, the part is

CC

compatible with JEDEC approved low voltage battery oper­ation (LVBO) interface specifications. T he device is als o
capable of standard 5-volt operation making it ideally suited
for dual sup ply rang e system s or car d produc ts that are
pluggable in both 3-volt and 5-volt hosts.

Atmel’s AT27BV 010 h as a dditio nal f eatures to en sur e hig h
quality and efficient producti on use. The Rapi d™ Progra m­ming Algori thm reduc es the time require d to prog ram the

part and guarantees reliable programming. Programming
time is typically only 100 µs/byte. The Integrated Product
Identification Code electronically identifi es the device and
manufacturer. This feature is used by industry standard
programming eq uipme nt to sele ct the prop er program ming
algorithms and voltages. The AT27BV010 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.
