Am29LV200
2 Megabit (256 K x 8-Bit/128 K x 16-Bit)
CMOS 3.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
a73 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
a73 High performance
— Full voltage range: access times as fast as 100
ns
— Regulated voltage range: access times as fast as
90 ns
a73 Ultra low power consumption (typical values at 5
MHz)
— 200 nA Automatic Sleep mode current
— 200 nA standby mode current
— 10 mA read current
— 20 mA program/erase current
a73 Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
three 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
three 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 via programming
equipment
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
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 Typical 1,000,000 write cycles per sector
(100,000 cycles minimum guaranteed)
a73 Package option
— 48-pin TSOP
— 44-pin SO
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
