1 / 70 page 1 P/N:PM0920 REV. 1.2, NOV. 05, 2003 MX29LV640T/B 64M-BIT [8M x 8/4M x 16] SINGLE VOLTAGE 3V ONLY FLASHMEMORY FEATURES GENERAL FEATURES • Single Power Supply Operation - 2.7 to 3.6 volt for read, erase, and program opera- tions • 8,388,608 x 8 / 4,194,304 x 16 switchable • Sector structure - 8KB (4KW) x 8 and 64KB(32KW) x 127 • 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. • 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: 90/120ns - Fast program time: 11us/word, 45s/chip (typical) - Fast erase time: 0.9s/sector, 45s/chip (typical) • Low Power Consumption - Low active read current: 10mA (typical) at 5MHz - Low standby current: 0.2uA (typ.) • Minimum 100,000 erase/program cycle • 20-year data retention 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 • WP Pin - Write protect (WP) function allows protection of two outermost boot sectors, regardless of sector protect status PACKAGE • 48-pin TSOP • 63-ball CSP • 64-ball Easy BGA GENERAL DESCRIPTION The MX29LV640T/B is a 64-mega bit Flash memory or- ganized as 8M bytes of 8 bits or 4M bytes of 16 bits. MXIC's Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV640T/B 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 MX29LV640T/B offers access time as fast as 90ns, allowing operation of high-speed microproces- sors without wait states. To eliminate bus contention, the MX29LV640T/B has separate chip enable (CE) and output enable (OE) controls. MXIC's Flash memories augment EPROM functionality with in-circuit electrical erasure and programming. The |
