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)
   — Standby mode: 1 µA
   — Read mode: 7 mA
   — Program/erase mode: 15 mA
■ Flexible sector architecture
   — One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and seven 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 write/erase cycles guaranteed
■ Package option
   — 32-pin PLCC
   — 32-pin TSOP
■ Compatibility with JEDEC standards
   — Pinout and software compatible with single power 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
