General Description
The S29GL256/128/064/032M family of devices are 3.0 V single power Flash memory manufactured using 0.23 um MirrorBit technology. The S29GL256M is a 256 Mbit, organized as 16,777,216 words or 33,554,432 bytes. The S29GL128M is a 128 Mbit, organized as 8,388,608 words or 16,777,216 bytes. The S29GL064M is a 64 Mbit, organized as 4,194,304 words or 8,388,608 bytes. The S29GL032M is a 32 Mbit, organized as 2,097,152 words or 4,194,304 bytes. Depending on the model number, the devices have an 8-bit wide data bus only, 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.
Access times as fast as 90 ns (S29GL128M, S29GL064M, S29GL032M) or 100 ns (S29GL256M) are available. Note that each access time has a specific operating voltage range (VCC) as specified in the Product Selector Guide and the Ordering Information sections. Package offerings include 40-pin TSOP, 48-pin TSOP, 56-pin TSOP, 48-ball finepitch BGA, 63-ball fine-pitch BGA and 64-ball Fortified BGA, depending on model number. Each device has separate
chip enable (CE#), write enable (WE#) and output enable (OE#) controls.

Software & Hardware Features
Software features
  - 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
  - Sector Group Protection: hardware-level method of preventing write operations within a sector group
  - Temporary Sector Unprotect: VID-level method of charging code in locked sectors
  - 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
