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
