• 159 PBGA, 13x22mm - 1.27mm pitch
1,000,000 Erase/Program Cycles
Sector Architecture
• Bank 1 (4Mb): eight 4K word, eight 32K word
www.DataSh•eeBt4aUn.kco2m(12Mb): twenty-four 32K word
• Bank 3 (12Mb): twenty-four 32K word
• Bank 4 (4Mb): eight 32K word
Bottom boot block
Zero Power Operation
Organized as 2Mx64 or 2x2Mx32
Commercial, Industrial and Military Temperature
Ranges
3.3 Volt for Read and Write Operations
Simultaneous Read/Write Operation:
• Data can be continuously read from one bank
while executing erase/program functions in
another bank
• Zero latency between read and write operations
Erase Suspend/Resume
• Suspends erase operations to allow programming
in same bank
Data# Polling and Toggle Bits
• Provides a software method of detecting the
status of program or erase cycles
Unlock Bypass Program command
• Reduces overall programming time when issuing
multiple program command sequences
Ready/Busy# output (RY/BY#)
• Hardware method for detecting program or erase
cycle completion
Hardware reset pin (RESET#)
• Hardware method of resetting the internal state
machine to the read mode
WP#/ACC input pin
• Write protect (WP#) function allows protection
two outermost boot sectors, 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
Note: For programming information refer to Flash Programming

NOTES:
1. Typical value for tWHWH1 is 7µs.
2. Typical value for tWHWH2 is 0.4 sec.
3. Guaranteed by design, but not tested.
4. Typical value is 36 sec. The typical chip programming time is considerably less than the maximum chip
programming time listed, since most bytes program faster than the maximum program times listed.
