1. General Description
The S29V/XS064R are 64 Mb, 1.8 Volt-only, Simultaneous Read/Write, Burst Mode flash memory devices, organized as 4,194,304
words of 16 bits each. These devices use a single VCC of 1.70 to 1.95 V to read, program, and erase the memory array. A 9.0-volt
VPP, may be used for faster program performance if desired. These devices can also be programmed in standard
EPROM programmers.
The devices operate within the temperature range of -25°C to +85°C, and are offered in Very Thin FBGA packages. The devices are
also available in the temperature range of -40°C to +85°C. Please refer to the Specification Supplement with Publication Number
S29VS064R_XS064R_SP for specification differences for devices offered in the -45°C to +85°C temperature range.
1.1 Simultaneous Read/Write Operations with Zero Latency
The Simultaneous Read/Write architecture provides simultaneous operation by dividing the memory space into four banks. The
device allows a host system to program or erase in one bank, then immediately and simultaneously read from another bank, with
zero latency. This releases the system from waiting for the completion of program or erase operations.
The VersatileIO™ (VIO) control allows the host system to set the voltage levels that the device generates at its data outputs and the
voltages tolerated at its data inputs to the same voltage level that is asserted on the VCCQ pin.
The devices use Chip Enable (CE#), Write Enable (WE#), Address Valid (AVD#) and Output Enable (OE#) to control asynchronous
read and write operations. For burst operations, the devices additionally require Ready (RDY) and Clock (CLK). This implementation
allows easy interface with minimal glue logic to microprocessors/microcontrollers for high performance read operations.
The devices offer complete compatibility with the JEDEC 42.4 single-power-supply flash command set standard. Commands
are written to the command register using standard microprocessor write timings. Reading data out of the device are similar to
reading from other flash or EPROM devices.
The host system can detect whether a program or erase operation is complete by using the device status bit DQ7 (Data# Polling)
and DQ6/DQ2 (toggle bits). After a program or erase cycle has been completed, the device automatically returns to reading array
data.
The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other
sectors. The devices are fully erased when shipped from the factory.
Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power
transitions. The devices also offers another type of data protection at the sector level. When VPP is at VIL, all sectors are locked.
The devices offer two power-saving features. When addresses have been stable for a specified amount of time, the device enters
the automatic sleep mode. The system can also place the device into the standby mode. Power consumption is greatly reduced in
both modes.
Device programming occurs by executing the program command sequence. This initiates the Embedded Program algorithm - an
internal algorithm that automatically times the program pulse widths and verifies proper cell margin. Additionally, Write Buffer
Programming is available on this family of devices. This feature provides superior programming performance by grouping locations
being programmed.
Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase algorithm - an internal
algorithm that automatically preprograms the array (if it is not already fully programmed) before executing the erase operation.
During erase, the device automatically times the erase pulse widths and verifies proper cell margin.
The Program Suspend/Program Resume feature enables the user to put program on hold to read data from any sector that is not
selected for programming. If a read is needed from the Dynamic Protection area, or the CFI area, after an program suspend, then
the user must use the proper command sequence to enter and exit this region. The program suspend/resume functionality is also
available when programming in erase suspend (1 level depth only).
The Erase Suspend/Erase Resume feature enables the user to put erase on hold to read data from, or program data to, any sector
that is not selected for erasure. True background erase can thus be achieved. If a read is needed from the Dynamic Protection area,
or the CFI area, after an erase suspend, then the user must use the proper command sequence to enter and exit this region.
The hardware RESET# pin terminates any operation in progress and resets the internal state machine to reading array data. The
RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the system
microprocessor to read boot-up firmware from the flash memory device.

The host system can detect whether a memory array program or erase operation is complete by using the device status bit DQ7
(Data# Polling), DQ6/DQ2 (toggle bits), DQ5 (exceeded timing limit), DQ3 (sector erase start timeout state indicator), and DQ1 (write
to buffer abort). After a program or erase cycle has been completed, the device automatically returns to reading array data.
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.
Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power
transitions. The device also offers another type of data protection at the sector level.
When the VPP pin = VIL, the entire flash memory array is protected.
Spansion Inc. 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. The data is programmed using hot electron
injection.
