GENERAL DESCRIPTION
The Am29F800B is an 8 Mbit, 5.0 volt-only Flash memory organized as 1,048,576 bytes or 524,288 words. The device is offered in 44-pin SO, 48-pin TSOP, and 48-ball FBGA packages. The device is also available in Known Good Die (KGD) form. For more information, refer to publication number 21631. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. A 12.0 V VPP is not required for write or erase operations. The device can also be programmed in standard EPROM programmers.

DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
   — 5.0 Volt-only operation for read, erase, and
      program operations
   — Minimizes system level requirements
■ Manufactured on 0.32 µm process technology
   — Compatible with 0.5 µm Am29F800 device
■ High performance
   — Access times as fast as 55 ns
■ Low power consumption (typical values at 5 MHz)
   — 1 µA standby mode current
   — 20 mA read current (byte mode)
   — 28 mA read current (word mode)
   — 30 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 via programming
      equipment
      Temporary Sector Unprotect feature allows code
      changes in previously locked sectors
■ 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 program/erase cycles per
   sector guaranteed
■ 20-year data retention at 125°C
   — Reliable operation for the life of the system
■ Package option
   — 48-pin TSOP
   — 44-pin SO
   — 48-ball FBGA
   — Known Good Die (KGD)
