GENERAL DESCRIPTION
The MX29LV320MT/B is a 32-mega bit Flash memory organized as 4M bytes of 8 bits or 2M bytes of 16 bits. MXICs Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV320MT/B is packaged in 44-pin SOP, 48-pin TSOP and 48-ball CSP. 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
• 4,194,304 x 8 / 2,097,152 x 16 switchable
• Sector structure
    - 8KB (4KW) x 8 and 64KB(32KW) x 63
• 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 OTP area for permanent, secure identification
    - Can be programmed and locked at factory or by customer
• 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
