1 / 59 page  ES I ES I 1 Rev. 0E May 25, 2006 ES29DL320 Excel Semiconductor inc. ADVANCED INFORMATION ES29DL320 32Mbit(4M x 8/2M x 16) CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory GENERAL FEATURES • Single power supply operation - 2.7V - 3.6V for read, program and erase operations • Simultaneous Read/Write operations - Data can be continuously read from one bank while executing erase/program functions in another bank - Zero latency between read and write operations • Multi-Bank architecture - Read may occur in any of the banks not being written or erased - Multi-Bank may be grouped by customer to achieve desired bank divisions • Top or Bottom boot block - ES29DL320T for Top boot block device - ES29DL320B for Bottom boot block device • A 256 bytes of extra sector for security code - Factory locked - Customer lockable • Package Options - 48-pin TSOP - 48-ball FBGA - All Pb-free products are RoHS-Compliant • Low Vcc write inhibit • Manufactured on 0.18um process technology • Compatible with JEDEC standards - Pinout and software compatible with single-power supply flash standard DEVICE PERFORMANCE • Read access time - 70ns/90ns for normal Vcc range ( 2.7V ~ 3.6V ) • Program and erase time - Program time : 6us/byte, 8us/word ( typical ) - Accelerated program time : 4us/word ( typical ) - Sector erase time : 0.7sec/sector ( typical ) • Power consumption (typical values) - 15uA in standby or automatic sleep mode - 10mA active read current at 5MHz - 15mA active write current during program or erase • Minimum 100,000 program/erase cycles per sector • 20 Year data retention at 125oC SOFTWARE FEATURES • Erase Suspend / Erase Resume • Data# poll and toggle for program/erase status • CFI ( Common Flash Interface) supported • Unlock Bypass Program • Autoselect mode • Auto-sleep mode after tACC + 30ns HARDWARE FEATURES • Hardware reset input pin ( RESET#) - Provides a hardware reset to device - Any internal device operation is terminated and the device returns to read mode by the reset • Ready/Busy# output pin ( RY/BY#) - Provides a program or erase operational status about whether it is finished for read or still being progressed • WP#/ACC input pin - Two outermost boot sectors are protected when WP# is set to low, regardless of sector protection - Program speed is accelerated by raising WP#/ACC to a high voltage (8.5V ~ 9.5V) • Sector protection / unprotection ( RESET# , A9 ) - Hardware method of locking a sector to prevent any program or erase operation within that sector - Two methods are provided : - In-system method by RESET# pin - A9 high-voltage method for PROM programmers • Temporary Sector unprotection ( RESET# ) - Allows temporary unprotection of previously protected sectors to change data in-system |
