ADVANCED INFORMATION
MX29LV640U
64M-BIT [4M x 16] CMOS EQUAL SECTOR FLASH MEMORY
FEATURES
GENERAL FEATURES
• 4,194,304 x 16 byte structure
• One hundred twenty-eight Equal Sectors with 32K
word each
- Any combination of sectors can be erased with erase
suspend/resume function
• Sector Protection/Chip Unprotect
- Provides sector group protect function to prevent
program or erase operation in the protected sector
group
- Provides chip unprotect function to allow code
changes
- Provides temporary sector group unprotect function
for code changes in previously protected sector groups
• Secured Silicon Sector
- Provides a 128-word area for code or data that can
be permanently protected.
Once this sector is protected, it is prohibited to pro-
gram or erase within the sector again.
• Single Power Supply Operation
- 2.7 to 3.6 volt for read, erase, and program opera-
tions
• Latch-up protected to 250mA from -1V to Vcc + 1V
• Low Vcc write inhibit is equal to or less than 1.5V
• Compatible with JEDEC standard
- Pinout and software compatible to single power sup-
ply Flash
SOFTWARE FEATURES
• Support Common Flash Interface (CFI)
- Flash device parameters stored on the device and
provide the host system to access.
• Erase Suspend/ Erase Resume
- Suspends sector erase operation to read data from
or program data to another sector which is not being
erased
• Status Reply
- Data polling & Toggle bits provide detection of pro-
gram and erase operation completion
HARDWARE FEATURES
• Ready/Busy (RY/BY) Output
- Provides a hardware method of detecting program
and erase operation completion
• Hardware Reset (RESET) Input
- Provides a hardware method to reset the internal
state machine to read mode
• 12V ACC input pin
- Provides accelerated program capability
• WP pin
- At VIL, allows protection of first or last sector, re-
gardless of sector protection/unprotected status
- At VIH, allows removal of protection
PERFORMANCE
• High Performance
- Fast access time: 90/120ns
- Fast program time: 11us/word, 115s/chip (typical)
- Fast erase time: 0.9s/sector, 48s/chip (typical)
• Low Power Consumption
- Low active read current: 9mA (typical) at 5MHz
- Low standby current: 0.2uA (typical)
• Minimum 100,000 erase/program cycle
• 20-year data retention
PACKAGE
• 48-pin TSOP
• 63-ball CSP
• 64-ball Easy BGA
GENERAL DESCRIPTION
The MX29LV640U is a 64-mega bit Flash memory orga-
nized as 4M bytes of 16 bits. MXIC's Flash memories
offer the most cost-effective and reliable read/write non-
volatile random access memory. The MX29LV640U is
packaged in 48-pin TSOP, 63-ball CSP and 64-ball Easy
BGA. It is designed to be reprogrammed and erased in
system or in standard EPROM programmers.
The standard MX29LV640U offers access time as fast
as 90ns, allowing operation of high-speed microproces-
sors without wait states. To eliminate bus contention,
the MX29LV640U has separate chip enable (CE) and
output enable (OE) controls.
MXIC's Flash memories augment EPROM functionality

Notes:
1.When the ACC pin is at VHH, the device enters the accelerated program mode. See "Accelerated Program Operations"
for more information.
2.The sector group protect and chip unprotect functions may also be implemented via programming equipment. See
the "Sector Group Protection and Chip Unprotect" section.
3.If WP=VIL, the first or last sector remains protected. If WP=VIH, the first or last sector will be protected or unprotected
as determined by the method described in "Sector Group Protection and Unprotect". All sectors are unprotected
when shipped from the factory (The Secured Silicon Sector may be factory protected depending on version ordered).
4.D or D as required by command sequence, data polling or sector protect algorithm (see Figure 2).
