General Description
The S29GL-N family of devices are 3.0-Volt single-power Flash memory manufactured using 110 nm MirrorBit technology. The S29GL064N is a 64-Mb device organized as 4,194,304 words or 8,388,608 bytes. The S29GL032N is a 32-Mb device organized as 2,097,152 words or 4,194,304 bytes. Depending on the model number, the devices have 16-bit wide data bus only, or a 16-bit wide data bus that can also function as an 8-bit wide data bus by using the BYTE# input. The devices can be programmed either in the host system or in standard EPROM programmers.
Distinctive Characteristics
Architectural Advantages
■ Single power supply operation
■ Manufactured on 110 nm MirrorBit process technology
■ Secured Silicon Sector region
– 128-word/256-byte sector for permanent, secure identification through an 8-word/16-byte random Electronic Serial Number, accessible through a command sequence
– Programmed and locked at the factory or by the customer
■ Flexible sector architecture
– 64Mb (uniform sector models): One hundred twenty-eight 32 Kword (64 KB) sectors
– 64 Mb (boot sector models): One hundred twenty-seven 32 Kword (64 KB) sectors + eight 4Kword (8KB) boot sectors
– 32 Mb (uniform sector models): Sixty-four 32Kword (64 KB) sectors
– 32 Mb (boot sector models): Sixty-three 32Kword (64 KB) sectors + eight 4Kword (8KB) boot sectors
■ Enhanced VersatileI/O™ Control
– All input levels (address, control, and DQ input levels) and outputs are determined by voltage on VIO input. VIO range is 1.65 to VCC
■ Compatibility with JEDEC standards
– Provides pinout and software compatibility for single-power supply flash, and superior inadvertent write protection
■ 100,000 erase cycles typical per sector
■ 20-year data retention typical
Performance Characteristics
■ High performance
– 90 ns access time
– 8-word/16-byte page read buffer
– 25 ns page read time
– 16-word/32-byte write buffer which reduces overall programming time for multiple-word updates
■ Low power consumption
– 25 mA typical initial read current, 1 mA typical page read current
– 50 mA typical erase/program current
– 1 µA typical standby mode current
■ Package options
– 48-pin TSOP
– 56-pin TSOP
– 64-ball Fortified BGA
– 48-ball fine-pitch BGA
Software & Hardware Features
■ Software features
– Advanced Sector Protection: offers Persistent Sector Protection and Password Sector Protection
– Program Suspend & Resume: read other sectors before programming operation is completed
– Erase Suspend & Resume: read/program other sectors before an erase operation is completed
– Data# polling & toggle bits provide status
– CFI (Common Flash Interface) compliant: allows host system to identify and accommodate multiple flash devices
– Unlock Bypass Program command reduces overall multiple-word programming time
■ Hardware features
– WP#/ACC input accelerates programming time (when high voltage is applied) for greater throughput during system production. Protects first or last sector regardless of sector protection settings on uniform sector models
– Hardware reset input (RESET#) resets device
– Ready/Busy# output (RY/BY#) detects program or erase cycle completion
