ADVANCED INFORMATION
ES29DL320
32Mbit(4M x 8/2M x 16)
CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory
GENERAL FEATURES
• Single powe r su pp ly 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 architectur e
- 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 sec urity 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 era se 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 prog ram/erase cycles per sector
• 20 Year data retention at 125

SOFTWARE FEATURES
• Erase Suspend / Erase Resume
• Data# poll and toggle for program/erase st atus
• CFI ( Common Flash Interface) supp orted
• Unlock Bypass Program
• Autoselec t mode
• Auto-sleep mode after t
ACC
+ 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 ( R Y/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
