Description
512K (64K x 8)
Unregulated
Battery-Voltage
High Speed
OTP
CMOS EPROM
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 consumption of a 3V supply. At VCC = 2.7V, any byte can be
accessed in less than 90 ns. With a typical power consumption of only 18 mW at 5
MHz and VCC = 3V, the AT27BV512 consumes less than one fifth the power of a
standard 5V EPROM.

System Considerations
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.
Switching between active and standby conditions via the
Chip Enable pin may produce transient voltage excursions. Unless accommodated by the system design, these
transients 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 utilized 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 is available in industry standard JEDECapproved 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.
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
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 AT27BV512 has additional features to ensure
high quality and efficient production use. The Rapid Programming 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.

*NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions beyond those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
Note:
1. Minimum voltage is -0.6V dc which may undershoot
to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is VCC + 0.75V dc which may be exceeded if certain precautions are observed (consult
application notes) and which may overshoot to
+7.0V for pulses of less than 20 ns.

AC Programming Characteristics
Rapid Programming Algorithm
TA = 25 ± 5°C, VCC = 6.5 ± 0.25V, OE/VPP = 13.0 ± 0.25V
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 verification / reprogramming loop is executed for
each address. In the event a byte fails to pass verification,
up to 10 successive 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.
