Atmel AT27BV010
Description
The Atmel AT27BV010 is a high-performance, low-power, low-voltage 1,048,576-bit, onetime programmable, read-only memory (OTP EPROM) organized as 128K 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.
The innovative Atmel 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 90ns. With a typical power draw of only 18mW at 5MHz and VCC = 3V, the
AT27BV010 consumes less than one-fifth the power of a standard, 5V EPROM. Standby
mode supply current is typically less than 1µA at 3V. The AT27BV010 simplifies system
design and stretches battery lifetime even further by eliminating the need for power supply
regulation.
The AT27BV010 is available in an industry-standard, JEDEC-approved, one-time
programmable (OTP) PLCC package. All devices feature two-line control (CE, OE) to give
designers the flexibility to prevent bus contention.
The AT27BV010 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, 5V operation, making it ideally suited for dual supply
range systems or card products that are pluggable in both 3V and 5V hosts.
The AT27BV010 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 100µs/byte. The
integrated product identification code electronically identifies the device and manufacturer.
0344I–EPROM–4/11
This feature is used by industry-standard programming equipment to select the proper programming algorithms and
voltages. The AT27BV010 programs in 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 produce transient voltage excursions. Unless
accommodated by the system design, these transients may exceed datasheet limits, resulting in device non-conformance.
At a minimum, a 0.1µF, 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 4.7µF 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.

Rapid programming algorithm
A 100µs PGM pulse width is used to program. The address is set to the first location. VCC is raised to 6.5V and VPP is raised
to 13.0V. Each address is first programmed with one 100µs PGM 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 100µs 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. VPP is then lowered to 5.0V and VCC to 5.0V. All bytes are read again and compared with the original data to
determine if the device passes or fails.
