GENERAL DESCRIPTION
The Am29LV800B is an 8 Mbit, 3.0 volt-only Flash memory organized as 1,048,576 bytes or 524,288 words. The device is offered in 48-ball FBGA, 44-pin SO, and 48-pin TSOP packages. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device requires only a single, 3.0 volt VCC supply to perform read, program, and erase operations. A standard EPROM programmer can also be used to program and erase the device.

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
   — Compatible with 0.5 µm Am29LV800 device
■ High performance
   — Full voltage range: access times as fast as 80 ns
   — Regulated voltage range: access times as fast
      as 70 ns
■ Ultra low power consumption (typical values at 5 MHz)
   — 200 nA Automatic Sleep mode current
   — 200 nA standby mode current
   — 7 mA read current
   — 15 mA program/erase current
■ Flexible sector architecture
   — One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
      fifteen 64 Kbyte sectors (byte mode)
   — One 8 Kword, two 4 Kword, one 16 Kword, and
      fifteen 32 Kword sectors (word mode)
   — Supports full chip erase
   — Sector Protection features:
      A hardware method of locking a sector to
      prevent any program or erase operations within
      that sector
      Sectors can be locked in-system or via
      programming equipment
      Temporary Sector Unprotect feature allows code
      changes in previously locked sectors
■ Unlock Bypass Program Command
   — Reduces overall programming time when
      issuing multiple program command sequences
■ Top or bottom boot block configurations
   available
■ Embedded Algorithms
   — Embedded Erase algorithm automatically
      preprograms and erases the entire chip or any
      combination of designated sectors
   — Embedded Program algorithm automatically
      writes and verifies data at specified addresses
■ Minimum 1,000,000 write cycle guarantee per
   sector
■ Package option
   — 48-ball FBGA
   — 48-pin TSOP
   — 44-pin SO
■ 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 operation completion
■ Ready/Busy# pin (RY/BY#)
   — Provides a hardware method of detecting
      program or erase cycle completion
■ Erase Suspend/Erase Resume
   — Suspends an erase operation to read data from,
      or program data to, a sector that is not being
      erased, then resumes the erase operation
■ Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
   array data
