AM29DL640G Datasheet | AMD

FEATURES - Data Management Software (DMS) - AMD-supplied software manages data programming, enabling EEPROM emulation - Eases historical sector erase flash limitations - Supports mon Flash Memory Interface (CFI) - Erase Suspend/Erase Resume - Suspends erase operations to allow reading from other sectors in same bank - Data# Polling and Toggle Bits - Provides a software method of detecting the status of program or erase cycles - Unlock Bypass Program mand - Reduces overall programming time when issuing multiple program mand sequences - Boot Sectors - Top and bottom boot sectors in the same device - Any bination of sectors can be erased - Manufactured on 0.17 µm process technology - Sec Si™ (Secured Silicon) Sector: Extra 256 Byte sector - Factory locked and identifiable: 16 bytes available for secure, random factory Electronic Serial Number; verifiable as factory locked through autoselect function. Express Flash option allows entire sector to be available for factory-secured data - Customer lockable: One-time programmable only. Once locked, data cannot be changed - Zero Power Operation - Sophisticated power management circuits reduce power consumed during inactive periods to nearly zero. - patible with JEDEC standards - Pinout and software patible with single-power-supply flash standard HARDWARE FEATURES - Ready/Busy# output (RY/BY#) - Hardware method for detecting program or erase cycle pletion - Hardware reset pin (RESET#) - Hardware method of resetting the internal state machine to the read mode - WP#/ACC input pin - Write protect (WP#) function protects sectors 0, 1, 140, and 141, regardless of sector protect status - Acceleration (ACC) function accelerates program timing - Sector protection - Hardware method of locking a sector, either in-system or using programming equipment, to prevent any program or erase operation within that sector - Temporary Sector Unprotect allows changing data in protected sectors in-system PACKAGE OPTIONS - 63-ball Fine Pitch BGA -...
