1. Description
The Atmel AT27LV010A is a high-performance, low-power, low-voltage 1,048,576-bit,
one-time programmable, read-only memory (OTP EPROM) organized as 128K by 8 bits. It
requires only one supply in the range of 3.0V to 3.6V in normal read mode operation, mak-
ing it ideal for fast, portable systems using battery power.
The Atmel innovative design techniques provide fast speeds that rival 5V parts, while keep-
ing the low power consumption of a 3.3V supply. At VCC = 3.0V, any byte can be accessed
in less than 70ns. With a typical power dissipation of only 18mW at 5MHz and VCC = 3.3V,
the AT27LV010A consumes less than one-fifth the power of a standard, 5V EPROM.
Standby mode supply current is typically less than 1µA at 3.3V.
The AT27LV010A is available in an industry-standard, JEDEC-approved, one-time program-
mable (OTP) PLCC package. All devices feature two-line control (CE, OE) to give
designers the flexibility to prevent bus contention.
The AT27LV010A operating with VCC at 3.0V produces TTL-level outputs that are compati-
ble with standard TTL logic devices operating at VCC = 5.0V. The device is also capable of
standard, 5V operation, making it ideally suited for dual supply range systems or card prod-
ucts that are pluggable in both 3V and 5V hosts.
The AT27LV010A has additional features to ensure high quality and efficient production use.
The rapid programming algorithm reduces the time required to program the part and guar-
antees reliable programming. Programming time is typically only 100µs/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 pro-
gramming algorithms and voltages. The AT27LV010A programs in exactly the same way as
a standard, 5V Atmel AT27C010, and uses the same programming equipment.

2. Pin configurations
3. 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 nonconformance.
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.

4. Absolute maximum ratings*
Note: 1. Minimum voltage is -0.6V DC, which may undershoot to -2.0V for pulses of less than 20ns. 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 20ns.
5. DC and AC characteristics
Table 5-1. Operating modes
Note: 1. X can be VIL or VIH.
2. Read, output disable, and standby modes require 3.0V 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 tog-
gled low (VIL) to select the manufacturer’s identification byte and high (VIH) to select the device code byte.

6. 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.
