Am29LV640D/Am29LV641D
64 Megabit (4 M x 16-Bit) CMOS 3.0 Volt-only
Uniform Sector Flash Memory with VersatileIO
DISTINCTIVE CHARACTERISTICS
Single power supply operation
— 3.0 to 3.6 volt read, erase, and program operations
VersatileIO
— Device generates output voltages and tolerates data
High performance
— Access times as fast as 90 ns
Manufactured on 0.23 µm process technology
CFI (Common Flash Interface) compliant
— Provides device-specific information to the system,
SecSi (Secured Silicon) Sector region
— 128-word sector for permanent, secure identification
— May be programmed and locked at the factory or by
— Accessible through a command sequence
Ultra low power consumption (typical values at 3.0 V,
5 MHz)
— 9 mA typical active read current
— 26 mA typical erase/program current
— 200 nA typical standby mode current
Flexible sector architecture
— One hundred twenty-eight 32 Kword sectors
Sector Protection
— A hardware method to lock a sector to prevent
— Sectors can be locked in-system or via programming
— Temporary Sector Unprotect feature allows code
Embedded Algorithms
— Embedded Erase algorithm automatically
— Embedded Program algorithm automatically writes
input voltages on the DQ input/ouputs as determined
by the voltage on V
allowing host software to easily reconfigure for
different Flash devices
through an 8-word random Electronic Serial Number
the customer
program or erase operations within that sector
equipment
changes in previously locked sectors
preprograms and erases the entire chip or any
combination of designated sectors
and verifies data at specified addresses

IO
Compatibility with JEDEC standards
— Pinout and software compatible with single-power
— Superior inadvertent write protection
Minimum 1 million erase cycle guarantee per sector
Package options
— 48-pin TSOP (Am29LV641DH/DL only)
— 56-pin SSOP (Am29LV640DH/DL only)
— 63-ball Fine-Pitch BGA (Am29LV640DU only)
— 64-ball Fortified BGA (Am29LV640DU only)
Erase Suspend/Erase Resume
— Suspends an erase operation to read data from, or
— or that is not being erased, then resumes the erase
Data# Polling and toggle bits
— Provides a software method of detecting program or
Unlock Bypass Program command
— Reduces overall programming time when issuing
Ready/Busy# pin (RY/BY#) (Am29LV640DU in FBGA
package only)
— Provides a hardware method of detecting program or
Hardware reset pin (RESET#)
— Hardware method to reset the device for reading array
WP# pin (Am29LV641DH/DL in TSOP,
Am29LV640DH/DL in SSOP only)
— At V
— At V
— An internal pull up to V
ACC pin
— Accelerates programming time for higher throughput
Program and Erase Performance (V
the ACC input pin)
— Word program time: 11 µs typical
— Sector erase time: 0.9 s typical for each 32 Kword
