Spansion Inc.
General Description
The Spansion S70GL02GP 2-Gigabit Mirrorbit Flash memory device is fabricated on 90 nm process technology. This device offers a fast page access time of 25 ns with a corresponding random access time of 110 ns. It features a Write Buffer that allows a maximum of 32 words/64 bytes to be programmed in one operation, resulting in faster effective programming time than standard single byte/word programming algorithms. This makes the device an ideal product for today’s embedded applications that require higher density, better performance and lower power consumption.
Distinctive Characteristics
■ Two 1024 Megabit (S29GL01GP) in a single 64-ball FortifiedBGA package (see publication S29GL-P_00 for full specifications)
■ Single 3V read/program/erase (3.0V - 3.6V)
■ 90 nm MirrorBit process technology
■ 8-word/16-byte page read buffer
■ 32-word/64-byte write buffer reduces overall programming time for multiple-word writes
■ Secured Silicon Sector region
– 128-word/256-byte sector for permanent, secure identification through an 8-word/16-byte random Electronic Serial Number
– Can be programmed and locked at the factory or by the customer
■ Uniform 64Kword/128KByte Sector Architecture
– S70GL02GP: two thousand forty-eight sectors
■ 100,000 erase cycles per sector typical
■ 20-year data retention typical
■ Offered Packages
– 64-ball Fortified BGA
■ Suspend and Resume commands for Program and Erase operations
■ Write operation status bits indicate program and erase operation completion
■ Unlock Bypass Program command to reduce programming time
■ Support for CFI (Common Flash Interface)
■ Persistent and Password methods of Advanced Sector Protection
■ WP#/ACC input
– Accelerates programming time (when VACC is applied) for greater throughput during system production
– Protects first or last sector of each die, regardless of sector protection settings
■ Hardware reset input (RESET#) resets device
■ Ready/Busy# output (RY/BY#) detects program or erase cycle completion
