16 Megabit (2 M x 8-Bit/1 M x 16-Bit)
CMOS 3.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
■
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
■
Manufactured on 0.23 µm process technology
— Fully compatible with 0.32 µm Am29LV160B device
■
High performance
— Access times as fast as 70 ns
■
Ultra low power consumption (typical values at
5 MHz)
— 200 nA Automatic Sleep mode current
— 200 nA standby mode current
— 9 mA read current
— 20 mA program/erase current
■
Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
thirty-one 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
thirty-one 32 Kword sectors (word mode)
— Supports full chip erase
— Sector Protection features:
A hardware method of locking a sector to prevent
any program or erase operations within that sector
Sectors can be locked in-system or via
programming equipment
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
■
Unlock Bypass Program Command
— Reduces overall programming time when issuing
multiple program command sequences
■
Top or bottom boot block configurations
available
■
Embedded Algorithms
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
— Embedded Program algorithm automatically
writes and verifies data at specified addresses
■
Minimum 1,000,000 write cycle guarantee
per sector
■
20-year data retention at 125
°
C
— Reliable operation for the life of the system
■
Package option
— 48-ball FBGA
— 48-pin TSOP
— 44-pin SO
■
CFI (Common Flash Interface) compliant
— Provides device-specific information to the
system, allowing host software to easily
reconfigure for different Flash devices
■
Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
■
Data# Polling and toggle bits
— Provides a software method of detecting program
or erase operation completion
■
Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion (not available
on 44-pin SO)
■
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
■
Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data
