MX29LV64xM H/L
FEATURES
GENERAL FEATURES
• Single Power Supply Operation
- 2.7 to 3.6 volt for read, erase, and program opera-
tions
• Configuration
- 8,388,608 x 8 / 4,194,304 x 16 switchable (for
MX29LV640M H/L)
- 4,194,304 x 16 (for MX29LV641M H/L)
• Sector structure
- 64KB(32KW) x 128
• 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/256-byte 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.
• 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
- Pin-out and software compatible to single power sup-
ply Flash
PERFORMANCE
• High Performance
- Fast access time: 90ns
- Page read time: 25ns
- Sector erase time: 0.5s (typ.)
- 4 word/8 byte page read buffer
- 16 word/ 32 byte write buffer: reduces programming
time for multiple-word/byte updates
64M-BIT SINGLE VOLTAGE 3V ONLY
UNIFORM SECTOR FLASH MEMORY
• Low Power Consumption
- Active read current: 18mA(typ.)
- Active write current: 20mA(typ.)
- Standby current: 20uA(typ.)
• Minimum 100,000 erase/program cycle
• 20-years data retention
SOFTWARE FEATURES
• Support Common Flash Interface (CFI)
- Flash device parameters stored on the device and
provide the host system to access.
• Program Suspend/Program Resume
- Suspend program operation to read other sectors
• Erase Suspend/ Erase Resume
- Suspends sector erase operation to read data/pro-
gram other sectors
• Status Reply
- Data# polling & Toggle bits provide detection of pro-
gram and erase operation completion
HARDWARE FEATURES
• Ready/Busy (RY/BY#) Output (for MX29LV640M H/L
only)
- 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
• WP#/ACC input
- Write protect (WP#) function allows protection high-
est or lowest sector, regardless of sector protection
settings
- ACC (high voltage) accelerates programming time
for higher throughput during system
PACKAGE
• 48-pin TSOP (for MX29LV641M H/L)
• 56-pin TSOP (for MX29LV640M H/L)
GENERAL DESCRIPTION
The MX29LV64xM H/L is a 64-mega bit Flash memory
organized as 8M bytes of 8 bits or 4M words of 16 bits
(for MX29LV640M H/L), or 4M words of 16bits (for
MX29LV641M H/L). MXIC's Flash memories offer the
most cost-effective and reliable read/write non-volatile
random access memory. The MX29LV64xM H/L is pack-
aged in 48-pin TSOP and 56-pin TSOP. It is designed to
be reprogrammed and erased in system or in standard
EPROM programmers.
The standard MX29LV64xM H/L offers access time as
fast as 90ns, allowing operation of high-speed micropro-
cessors without wait states. To eliminate bus conten-
tion, the MX29LV64xM H/L has separate chip enable

Notes:
1. Address are A21:A0 in word mode; A21:A-1 in byte mode. Sector addresses are A21:A15 in both modes.
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 sectors remain protected. If WP#=VIH, the highest or lowest sector protection depends on
whether they were last protected or unprotect using the method described in "Sector/ Sector Block Protection and
Unprotect".
4. DIN or DOUT as required by command sequence, Data# polling or sector protect algorithm (see Figure 15).
