Am29LV800B
8 Megabit (1 M x 8-Bit/512 K x 16-Bit)
CMOS 3.0 Vo lt -only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
Single power supply operation
Full v olt age r ange: 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
Manufact ured on 0.35 µm process technology
Compatible with 0.5 µm Am29LV800 device
High performan ce
Full voltage r ange: access times as fast as 80 ns
Regulated voltage range: 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
7 mA read current
15 mA program/erase current
Flexible sector architecture
O ne 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 Prot ection features:
A hardware method of locking a sector to
prevent any program or erase oper ations within
that sector
Sectors can be locked in-system or via
programming equipment
Temporary Sector Unprotect feature allows code
changes in prev iously locked sectors
Unlock Bypass Program Comm an d
Reduces overall programming time when
issuing multiple program command sequences
Top or bottom boot block configurations
available
Embedded Al gorithms
Embedded Erase algorithm automatically
preprogr ams and erases the entire chip or any
combination of designated sectors
Embedded Program algorithm automatically
writes and verifies data at specif ied addresses
Minimum 1,000,000 write cycle guarantee per
sector
Package option
48-ball FBGA
48-pin TSOP
44-pin SO
Compatibility with JEDEC standards
Pinout and software compatible with single-
power supply Flash
Superior inadvertent write protection
Data# Polling and toggle bits
P rovides 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
Erase Suspend/Erase Resume
Suspends an erase oper ation to read data from,
or progr am data to, a sector that is not being
erased, then res umes the erase operation
Hardware reset pin (RESET#)
Hardw are method to reset the de vice t o reading
array data
