Description
AT27BV512
The AT27BV512 is a high performance, low power, low voltage 524,288-bit one-time
programmable read only memory (OTP EPROM) organized as 64K by 8 bits. It
requires only one supply in the range of 2.7V to 3.6V in normal read mode operation,
making it ideal for fast, portable systems using either regulated or unregulated battery
power.

Atmel’s innovative design techniques provide fast speeds
that rival 5V parts while keeping the low power consump-
tion of a 3V supply. At VCC = 2.7V, any byte can be
accessed in less than 70 ns. With a typical power con-
sumption of only 18 mW at 5 MHz and VCC = 3V, the
AT27BV512 consumes less than one fifth the power of a
standard 5V EPROM.
ming Algorithm reduces the time required to program the
part and guarantees reliable programming. Programming
time is typically only 100 µs/byte. The Integrated Product
Identification Code electronically identifies the device and
manufacturer. This feature is used by industry standard
programming equipment to select the proper programming
algorithms and voltages. The AT27BV512 programs
exactly the same way as a standard 5V AT27C512R and
uses the same programming equipment.
Standby mode supply current is typically less than 1 µA at
3V. The AT27BV512 simplifies system design and
stretches battery lifetime even further by eliminating the
need for power supply regulation.
System Considerations
The AT27BV512 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.
Switching between active and standby conditions via the
Chip Enable pin may produce transient voltage excursions.
Unless accommodated by the system design, these tran-
sients may exceed data sheet limits, resulting in device
non-conformance. At a minimum, a 0.1 µF high frequency,
low inherent inductance, ceramic capacitor should be uti-
lized for each device. This capacitor should be connected
between the VCC 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 µF bulk electrolytic capacitor should
be utilized, again connected between the VCC and Ground
terminals. This capacitor should be positioned as close as
possible to the point where the power supply is connected
to the array.
The AT27BV512 operating with VCC at 3.0V produces TTL
level outputs that are compatible with standard TTL logic
devices operating at VCC = 5.0V. At VCC = 2.7V, the part is
compatible with JEDEC approved low voltage battery oper-
ation (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 AT27BV512 has additional features to ensure high
quality and efficient production use. The Rapid™ Program-

Notes: 1. X can be VIL or VIH.
2. Read, output disable, and standby modes require, 2.7V ≤ VCC ≤ 3.6V, or 4.5V ≤ VCC ≤ 5.5V.
3. Refer to Programming Characteristics. Programming modes require VCC = 6.5V.
4. VH = 12.0 ± 0.5V.
5. Two identifier bytes may be selected. All Ai inputs are held low (VIL), except A9 which is set to VH and A0 which is toggled low
(VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte.

RapidProgramming Algorithm
A 100 µs CE pulse width is used to program. The address
is set to the first location. VCC is raised to 6.5V and OE/VPP
is raised to 13.0V. Each address is first programmed with
one 100 µs CE pulse without verification. Then a verifica-
tion / reprogramming loop is executed for each address. In
the event a byte fails to pass verification, up to 10 succes-
sive 100 µs pulses are applied with a verification after each
pulse. If the byte fails to verify after 10 pulses have been
applied, the part is considered failed. After the byte verifies
properly, the next address is selected until all have been
checked. OE/VPP is then lowered to VIL and VCC to 5.0V. All
bytes are read again and compared with the original data to
determine if the device passes or fails.
