1 / 74 page 1 P/N:PM1079 REV. 1.2, FEB. 27, 2006 MX29LV640MT/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: 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: 50mA(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 Resume - Suspends programming operation to read data from other sectors • Erase Suspend/ Erase Resume - Suspends sector erase operation to read/program other sectors • 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#/ACC input - Write protect (WP#) function allows protection of two outermost boot sectors, regardless of sector protect status - ACC (high voltage) accelerates programming time for higher throughput during system PACKAGE • 48-pin TSOP • 63-ball CSP • All Pb-free devices are RoHS Compliant GENERAL DESCRIPTION The MX29LV640MT/B is a 64-mega bit Flash memory organized as 8M bytes of 8 bits or 4M words of 16 bits. MXIC's Flash memories offer the most cost-effective and reliable read/write non-volatile random access memory. The MX29LV640MT/B is packaged in 48-pin TSOP, 63- ball CSP. It is designed to be reprogrammed and erased in system or in standard EPROM programmers. The standard MX29LV640MT/B offers access time as fast as 90ns, allowing operation of high-speed micropro- cessors without wait states. To eliminate bus conten- tion, the MX29LV640MT/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 |
