Almet Atmel's innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consump- tion of a 3.3V supply. At Voc = 3.0V, any byte can be accessed in less than 70 ns. With a typical power dissipa- tion of only 18 mW at 5 MHz and Vgg = 3.8V, the AT27LV010A consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typi- cally less than 1 WA at 3.3V. The AT27LV010A is available in industry standard JEDEC- approved one-time programmable (OTP) plastic PLCC and TSOP packages. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention. The AT27LV010A operating with Vou at 3.0V produces TTL level outputs that are compatible with standard TTL logic devices operating at Vog = 5.0V. The device is also capa- ble of standard 5-volt operation making it ideally suited for dual supply range systems or card products that are plug- gable in both 3-volt and 5-volt hosts. Atmel's AT27LV010A has additional features to ensure high quality and efficient production use. The Rapid Pro- gramming Algorithm reduces the time required to program the part and guarantees reliable programming. Program- ming time is typically only 100 us/byte. The Integrated Block Diagram 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 pro- grams 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 tran- sients may exceed data sheet limits, resulting in device non-conformance. At a minimum, a 0.1 WF 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 uF bulk electrolytic capacitor should be utilized, again connected between the Voc and Ground terminals. This capacitor should be positioned as close as possible to the point where the power supply is connected to the array.
