GENERAL DESCRIPTION
The Am29PL320D is a 32 Mbit, 3.0 Volt-only page mode Flash memory device organized as 2,097,152 words or 1,048,576 double words. The device is offered in an 84-ball FBGA package. The word-wide data (x16) appears on DQ15–DQ0; the double wordwide (x32) data appears on DQ31–DQ0. The device is available in both top and bottom boot versions. This device can be programmed in-system or with in standard EPROM programmers. A 12.0 V VPP or 5.0 VCC are not required for write or erase operations.

DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
■ 32 Mbit Page Mode device
   — Word (16-bit) or double word (32-bit) mode
      selectable via WORD# input
   — Page size of 8 words/4 double words: Fast page
      read access from random locations within the
      page
■ 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
■ Flexible sector architecture
   — Sector sizes (x16 configuration): One 16 Kword,
      two 8 Kword, one 96 Kword and fifteen 128
      Kword sectors
   — Supports full chip erase
■ SecSi™ (Secured Silicon) Sector region
   — Current version of device has 512 words (256
      double words); future versions will have 128
      words (64 double words)
■ Top or bottom boot block configuration
■ Manufactured on 0.23 µm process technology
■ 20-year data retention at 125°C
■ Minimum 1 million erase cycles guarantee
   per sector
