It requires only one supply in the range of 3.0V to 3.6V in normal read mode operation, making it ideal for fast, portable systems using battery power. The Atmel innovative design techniques provide fast speeds that rival 5V parts, while keeping 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 programmable (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 compatible 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 products 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 guarantees 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 programming algorithms and voltages. The AT27LV010A programs in exactly the same way as a standard, 5V Atmel AT27C010, and uses the same programming equipment. 0548F–EPROM–4/11 Pin configurations Addresses O0 - O7 Outputs CE Chip enable OE Output enable PGM Program strobe NC No connect A12 A15 A16 VPP VCC PGM NC A0 - A16 32-lead PLCC Top view A7 A6 A5 A4 A3 A2 A1 A0 O0 4 3 2 1 32 31 30 Function 5 6 7 8 9 10 11 12 13 29 28 27 26 25 24 23 22 21 14 15 16 17 18 19 20 Pin name A14 A13 A8 A9 A11 OE A10 CE O7 O1 O2 GND O3 O4 O5 O6 2. 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.

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.
