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.  

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

PERFORMANCE CHARACTERISTICS
■ High performance read access times
   — Page access times as fast as 20 ns
   — Random access times as fast as 60 ns
■ Power consumption (typical values)
   — Initial page read current: 4 mA (1 MHz),
      40 mA (10 MHz)
   — Intra-page read current: 15 mA (10 MHz),
      50 mA (33 MHz)
   — Program/erase current: 25 mA
   — Standby mode current: 2 µA

SOFTWARE FEATURES
■ Software command-set compatible with JEDEC
   standard
   — Backward compatible with Am29F and Am29LV
      families
■ CFI (Common Flash Interface) compliant
   — Provides device-specific information to the
      system, allowing host software to easily
      reconfigure for different Flash devices
■ Unlock Bypass Program Command
   — Reduces overall programming time when
      issuing multiple program command sequences
■ 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 FEATURES
■ Sector Protection
   — 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 command
      sequence allows code changes in previously
      locked sectors
■ ACC (Acceleration) input provides faster
   programming times
■ WP# (Write Protect) input
   — At VIL, protects the first or last 32 Kword sector,
      regardless of sector protect/unprotect status
   — At VIH, allows removal of sector protection
   — An internal pull up to VCC is provided
■ Package Options
   — 84-ball FBGA
