4 Megabit (512 K x 8-Bit)
CMOS 3.0 Volt-only, Uniform Sector 32-Pin Flash Memory
DISTINCTIVE CHARACTERISTICS
I
Single power supply operation
— Full voltage range: 2.7 to 3.6 volt read and write
operations for battery-powered applications
— Regulated voltage range: 3.0 to 3.6 volt read and
write operations and for compatibility with high
performance 3.3 volt microprocessors
I
Manufactured on 0.32 μm process technology
I
High performance
— Full voltage range: access times as fast as 70 ns
— Regulated voltage range: access times as fast as
60 ns
I
Ultra low power consumption (typical values at
5 MHz)
— Automatic sleep mode: 1 μA
— Standby mode: 1 μA
— Read mode: 7 mA
— Program/erase mode: 15 mA
I
Flexible sector architecture
— Eight 64 Kbyte sectors
— Any combination of sectors can be erased;
supports full chip erase
— Sector Protection features:
Hardware method of locking a sector to prevent
any program or erase operations within that sector
Sectors can be locked via programming
equipment
I
Unlock Bypass Program Command
— Reduces overall programming time when issuing
multiple program command sequences
I
Embedded Algorithms
— Embedded Erase algorithms automatically
preprogram and erase the entire chip or any
combination of designated sectors
— Embedded Program algorithms automatically
writes and verifies data at specified addresses
I
Minimum 1,000,000 write/erase cycles
guaranteed
I
20-year data retention at 125
°
C
— Reliable operation for the life of the system
I
Package option
— 32-pin PLCC
— 32-pin TSOP
I
Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
I
Data# Polling and toggle bits
— Provides a software method of detecting program
or erase cycle completion
I
Erase Suspend/Resume
— Supports reading data from or programming data
to a sector not being erased
