S29GL032N90TFI040 Product Details

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.
Access times as fast as 90 ns 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–S29GL032N, and Ordering Information–S29GL064N. Package offerings include 48-pin TSOP, 56-pin TSOP, 48-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.
Each device requires only a single 3.0-Volt power supply for both read and write functions. In addition to a VCC input, a high-voltage accelerated program (ACC) feature provides shorter programming times through increased current on the WP#/ACC input. This feature is intended to facilitate factory throughput during system production, but may also be used in the field if desired.
The device is entirely command set compatible with the JEDEC single-power-supply Flash standard. Commands are written to the device using standard microprocessor write timing. Write cycles also internally latch addresses and data needed for the programming and erase operations.
The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory.
The Advanced Sector Protection features several levels of sector protection, which can disable both the program and erase operations in certain sectors. Persistent Sector Protection is a method that replaces the previous 12-volt controlled protection method. Password Sector Protection is a highly sophisticated protection method that requires a password before changes to certain sectors are permitted. 
Device programming and erasure are initiated through command sequences. Once a program or erase operation begins, the host system need only poll the DQ7 (Data# Polling) or DQ6 (toggle) status bits or monitor the Ready/Busy# (RY/BY#) output to determine whether the operation is complete. To facilitate programming, an Unlock Bypass mode reduces command sequence overhead by requiring only two write cycles to program data instead of four.
Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of sectors of memory. This can be achieved in-system or via programming equipment.
The Erase Suspend/Erase Resume feature allows the host system to pause an erase operation in a given sector to read or program any other sector and then complete the erase operation. The Program Suspend/ Program Resume feature enables the host system to pause a program operation in a given sector to read any other sector and then complete the program operation.
The hardware RESET# pin terminates any operation in progress and resets the device, after which it is then ready for a new operation. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the host system to read boot-up firmware from the Flash memory device.
The device reduces power consumption in the standby mode when it detects specific voltage levels on CE# and RESET#, or when addresses are stable for a specified period of time.
The Write Protect (WP#) feature protects the first or last sector by asserting a logic low on the WP#/ACC pin or WP# pin, depending on model number. The protected sector is still protected even during accelerated programming.
The Secured Silicon Sector provides a 128-word/256-byte area for code or data that can be permanently protected. Once this sector is protected, no further changes within the sector can occur. Spansion MirrorBit flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness.
The device electrically erases all bits within a sector simultaneously via hot-hole assisted erase. The data is programmed using hot electron injection.
