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). MXICs Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV64xM H/L is packaged in 48-pin TSOP and 56-pin TSOP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers.

FEATURES
GENERAL FEATURES
• Single Power Supply Operation
    - 2.7 to 3.6 volt for read, erase, and program operations
• 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 program 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 supply 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
• 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/program other sectors
• Status Reply
    - Data# polling & Toggle bits provide detection of program 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 highest 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)
