Am29LV800B Known Good Die
8 Megabit (1 M x 8-Bit/512 K x 16-Bit)
CMOS 3.0 Volt-only, Boot Sector Flash Memory—Die Revision 1
DISTINCTIVE CHARACTERISTICS
a73 Single power supply operation
— 2.7 to 3.6 V for read, program, and erase
operations
— Ideal for battery-powered applications
a73 Manufactured on 0.35 µm process technology
a73 High performance
— 90 or 120 ns access time
a73 Low power consumption (typical values at 5
MHz)
— 200 nA Automatic Sleep mode current
— 200 nA standby mode current
— 7 mA read current
— 15 mA program/erase current
a73 Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
fifteen 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
fifteen 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
a73 Unlock Bypass Program Command
— Reduces overall programming time when
issuing multiple program command sequences
a73 Top or bottom boot block configurations
available
a73 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
a73 Minimum 1,000,000 write cycle guarantee per
sector
a73 Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
a73 Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
a73 Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion
a73 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
a73 Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data
