It requires only one supply in the range of 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 100 ns. With a typical power dissipation of only 18 mW at 5 MHz and VCC = 3V, the AT27BV040 consumes less than one fifth the power of a standard 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V. The AT27BV040 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. The AT27BV040 is available in industry-standard JEDEC-approved one-time programmable OTP plastic PLCC, TSOP, and VSOP packages. All devices feature twoline control CE, OE to give designers the flexibility to prevent bus contention. The AT27BV040 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. 4-Megabit 512K x 8 Unregulated Battery-Voltage High-Speed OTP EPROM AT27BV040 Atmel’s AT27BV040 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 AT27BV040 programs exactly the same way as a standard 5V AT27C040 and uses the same programming equipment.

Unless accommodated by the system design, these transients may exceed datasheet limits, resulting in device non-conformance. At a minimum, a 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 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.
