32Mbit(4M x 8/2M x 16)  
CMOS 3.0 Volt-only, Boot Sector Flash Memory  
• Minimum 100,000 program/erase cycles per sector  
• 20 Year data retention at 125oC  
GENERAL FEATURES  
• Single power supply operation  
- 2.7V ~ 3.6V for read, program and erase operations  
SOFTWARE FEATURES  
• Sector Structure  
- 8Kbyte x 8 boot sectors  
- 64Kbyte x 63 sectors  
- 256byte security sector  
• 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  
• Top or Bottom boot block  
- ES29LV320ET for Top boot block device  
- ES29LV320EB for Bottom boot block device  
• A 256 bytes of extra sector for security code  
- Factory locked  
HARDWARE FEATURES  
- Customer lockable  
• 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  
• Package Options  
- 48-pin TSOP  
- 48-ball FBGA  
- Pb-free packages  
- All Pb-free products are RoHS-Compliant  
• Ready/Busy# output pin (RY/BY#)  
- Provides a program or erase operational status  
about whether it is finished for read or still being  
progressed  
• Low Vcc write inhibit  
• Manufactured on 0.18um process technology  
• Compatible with JEDEC standards  
- Pinout and software compatible with single-power  
supply flash standard  
• 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 (11.5V~12.5V)  
DEVICE PERFORMANCE  
• 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 :  
• Read access time  
- 70ns/90ns for normal Vcc range ( 2.7V ~ 3.6V )  
• Program and erase time  
- In-system method by RESET# pin  
- A9 high-voltage method for PROM programmers  
- Program time : 6us/byte, 8us/word ( typical )  
- Accelerated program time : 4us/word ( typical )  
- Sector erase time : 0.7sec/sector ( typical )  
• Temporary Sector Unprotection (RESET# )  
- Allows temporary unprotection of previously  
protected sectors to change data in-system  
• 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
