DISTINCTIVE CHARACTERISTICS
s
Single power supply operation
— 5.0 V
±
10% for read, erase, and program
operations
— Simplifies system-level power requirements
s
High performance
— 70 ns maximum access time
s
Low power consumption
— 20 mA typical active read current for byte mode
— 28 mA typical active read current for word mode
— 30 mA typical program/erase current
— 25
µA
typical standby current
s
Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
one 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
one 32 Kword sectors (word mode)
— Any combination of sectors can be erased
— Supports full chip erase
s
Top or bottom boot block configurations
available
s
Sector protection
— Hardware-based feature that disables/re-
enables program and erase operations in any
combination of sectors
— Sector protection/unprotection can be
implemented using standard PROM
programming equipment
— Temporary Sector Unprotect feature allows in-
system code changes in protected sectors
s
Embedded Algorithms
— Embedded Erase algorithm automatically
pre-programs and erases the chip or any
combination of designated sector
— Embedded Program algorithm automatically
programs and verifies data at specified address
s
Minimum 100,000 program/erase cycles
guaranteed
s
Package options
— 44-pin SO
— 48-pin TSOP
s
Compatible with JEDEC standards
— Pinout and software compatible with
single-power-supply flash
— Superior inadvertent write protection
s
Data# Polling and Toggle Bits
— Provides a software method of detecting
program or erase cycle completion
s
Ready/Busy pin (RY/BY#)
— Provides a hardware method for detecting
program or erase cycle completion
s
Erase Suspend/Erase Resume
— Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
s
Hardware RESET# pin
— Hardware method of resetting the device to
reading array data
