GENERAL DESCRIPTION
The Am29LV040B 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 accomplished using only a single power supply. The device can also be programmed in standard EPROM programmers.

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 0.32 µm process technology
■ High performance
    — Full voltage range: access times as fast as 70 ns
    — Regulated voltage range: access times as fast as 60 ns
■ Ultra low power consumption (typical values at 5 MHz)
    — Automatic sleep mode: 0.2 µA
    — Standby mode: 0.2 µA
    — Read mode: 7 mA
    — Program/erase mode: 15 mA
■ Flexible sector architecture
    — Eight 64 Kbyte sectors
    — Any combination of sectors can be erased; supports full chip erase
    — Sector Protection features:
        Hardware method of locking a sector to prevent any program or erase operations within that sector
        Sectors can be locked via programming equipment
■ Unlock Bypass Program Command
    — Reduces overall programming time when issuing multiple program command sequences
■ Embedded Algorithms
    — Embedded Erase algorithms automatically preprogram and erase the entire chip or any combination of designated sectors
    — Embedded Program algorithms automatically writes and verifies data at specified addresses ■ Minimum 1,000,000 erase cycles guaranteed
■ 20-year data retention at 125°C
    — Reliable operation for the life of the system
■ Package option
    — 32-pin PLCC
    — 32-pin TSOP
■ Compatibility with JEDEC standards
    — Pinout and software compatible with singlepower supply Flash
    — Superior inadvertent write protection
■ Data# Polling and toggle bits
    — Provides a software method of detecting program or erase cycle completion
■ Erase Suspend/Resume
    — Supports reading data from or programming data to a sector not being erased
