MICROCHIP AT27BV010-12TC

The AT27BV010 is a high-performance, low-power, low-voltage 1,048,576-bit OTP EPROM organized as 128K x 8 bits. For normal read mode operation, it requires only a single 2.7V to 3.6V power supply, making it ideal for fast portable systems powered by regulated or unregulated batteries. Atmel's innovative design technology achieves high-speed performance comparable to 5V devices while maintaining the low-power characteristics of a 3V supply. At VCC = 2.7V, access time for any byte is less than 90 ns. At 5 MHz and VCC = 3V, typical power consumption is only 18 mW — less than one-fifth that of a standard 5V EPROM. At 3V, standby supply current is typically less than 1 μA. By eliminating the need for power supply regulation, the AT27BV010 simplifies system design and further extends battery life. The AT27BV010 is offered in industry-standard, JEDEC-approved OTP plastic PLCC, TSOP, and VSOP packages. All devices feature two-line control (CE, OE), giving designers the flexibility to avoid bus contention. When VCC is 3.0V, the AT27BV010 generates TTL-level outputs compatible with standard TTL logic devices operating at VCC = 5.0V. At VCC = 2.7V, the device is compatible with the JEDEC-approved Low Voltage Battery Operation (LVBO) interface specification. The device also supports standard 5V operation, making it well suited for dual-supply-range systems or card products that can be inserted into both 3V and 5V hosts. Atmel's AT27BV010 incorporates additional features to ensure high-quality and efficient production use. The Rapid™ programming algorithm reduces the time required to program the device and guarantees reliable programming. Programming time is typically only 100 μs/byte. An integrated product identification code allows electronic identification of both the device and the manufacturer. This feature is used by industry-standard programming equipment to select the appropriate programming algorithm and voltage. The AT27BV010 is programmed in exactly the same manner as the standard 5V AT27C010 and uses the same programming equipment.
