GENERAL DESCRIPTION
The Am29LV104B is a single power supply, 4 Mbit, 3.0 Volt-only Flash memory device organized as 524,288 bytes. The data appears on DQ0-DQ7. The device is available in 32-pin PLCC and 32-pin TSOP packages. All read, erase, and program operations are accom plished using only a single power supply. The device can also be programmed in standard EPROM pro grammers.
DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
— Full voltage range: 2.7 to 3.6 volt read and write operations for battery-powered applications
— Regulated voltage range: 3.0 to 3.6 volt read and write operations and for compatibility with high performance 3.3 volt microprocessors
■ Manufactured on 0.35 µm process technology
■ High performance
— Full voltage range: access times as fast as 70 ns
— Regulated voltage range: access times as fast as 55 ns
■ Ultra low power consumption
— Automatic sleep mode: 1 µA (typical values at 5 MHz)
