General Description
The S70GL01GN00 is a 1024 Mbit, single power supply flash memory device organized as two S29GL512N dies in a single 64-ball Fortified-BGA package. Each S29GL512N die is 512 Mbit, organized as 33,554,432 words or 67,108,864 bytes. The devices have a 16-bit wide data bus that can also function as an 8-bit wide data bus by using the BYTE# input. The device can be programmed either in the host system or in standard EPROM programmers.
Access times as fast as 110 ns is available. Note that each access time has a specific operating voltage range (VCC) and an I/O voltage range (VIO), as specified in the Product Selector Guide‚ on page 5 and the Ordering Information‚ on page 9. The devices are offered in a 56-pin TSOP or 64-ball Fortified BGA package. Each device has separate chip enable (CE# or CE2#), 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 (WP#/ACC) input provides shorter programming times through increased current. This feature is intended to facilitate factory throughput during system production, but may also be used in the field if desired.
The devices are entirely command set compatible with the JEDEC singlepower-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.
Device programming and erasure are initiated through command sequences. Once a program or erase operation starts, 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. Persistent Sector Protection provides in-system, command-enabled protection of any combination of sectors using a single power supply at VCC. Password Sector Protection prevents unauthorized write and erase operations in any combination of sectors through a user-defined 64-bit password.
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.

Software & Hardware Features
*Software features
- Program Suspend and Resume: read other sectors before programming operation is completed
- Erase Suspend and Resume: read/program other sectors before an erase operation is completed
- Data# polling and toggle bits provide status
- Unlock Bypass Program command reduces overall multiple-word programming time — CFI (Common Flash Interface) compliant: allows host system to identify and accommodate multiple flash devices
*Hardware features
- Advanced Sector Protection
- 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
- Hardware reset input (RESET#) resets device
- Ready/Busy# output (RY/BY#) detects program or erase cycle completion

DESCRIPTION
The MBM29LV320TE/BE is 32 M-bit, 3.0 V-only Flash memory organized as 4 M bytes of 8 bits each or 2 M words of 16 bits each. The device is offered in a 48-pin TSOP (1) and 63-ball FBGA packages. This device is designed to be programmed in-system with the standard system 3.0 V VCC supply. 12.0 V VPP and 5.0 V VCC are not required for write or erase operations. The device can also be reprogrammed in standard EPROM programmers.
The standard device offers access times 80 ns, 90 ns and 100 ns, allowing operation of high-speed microprocessors without wait state. To eliminate bus contention the device has separate chip enable(CE), write enable(WE) and output enable (OE) controls.
The device is pin and command set compatible with JEDEC standard E2PROMs. Commands are written to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from 5.0 V and 12.0 V Flash or EPROM devices.
The device is programmed by executing the program command sequence. This invokes the Embedded Program Algorithm which is an internal algorithm that automatically times the program pulse widths and verifies proper cell margin. Typically, each sector can be programmed and verified in about 0.5 seconds. Erase is accomplished by executing the erase command sequence. This invokes the Embedded Erase Algorithm which is an internal algorithm that automatically preprograms the array if it is not already programmed before executing the erase
operation. During erase, the device automatically time the erase pulse widths and verify proper cell margin.
A sector is Typically erased and verified in 1.0 second. (If already completely preprogrammed.) The device also features a sector erase architecture. The sector mode allows each sector to be erased and reprogrammed without affecting other sectors. The device is erased when shipped from the factory.
The device features single 3.0 V power supply operation for both read and write functions. Internally generated and regulated voltages are provided for the program and erase operations. A low VCC detector automatically inhibits write operations on the loss of power. The end of program or erase is detected by Data Polling of DQ7, by the Toggle Bit feature on DQ6, or the RY/BY output pin. Once the end of a program or erase cycle is completed, the device internally resets to the read mode.
The device also has a hardware RESET pin. When this pin is driven low, execution of any Embedded Program Algorithm or Embedded Erase Algorithm is terminated. The internal state machine is then reset to the read mode. The RESET pin may be tied to the system reset circuitry. Therefore, if a system reset occurs during the Embedded Program Algorithm or Embedded Erase Algorithm, the device is automatically reset to the read mode and will have erroneous data stored in the address locations being programmed or erased. These locations
need re-writing after the reset. Resetting the device enables the system’s microprocessor to read the boot-up firmware from the Flash memory.
Fujitsu Flash technology combines years of EPROM and E2PROM experience to produce the highest levels of quality, reliability, and cost effectiveness. The device memory electrically erase the entire chip or all bits within a sector simultaneously via Fowler-Nordhiem tunneling. The bytes/words are programmed one byte/word at a time using the EPROM programming mechanism of hot electron injection.
