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
