AM29LV641DH101REIN

64 Megabit (4 M x 16-Bit) CMOS 3.0 Volt-only Uniform Sector Flash Memory with VersatileIO Control

Advanced Micro Devices 

Am29LV640D/Am29LV641D

64 Megabit (4 M x 16-Bit) CMOS 3.0 Volt-only

Uniform Sector Flash Memory with VersatileIO Control

DISTINCTIVE CHARACTERISTICS

s Single power supply operation

— 3.0 to 3.6 volt read, erase, and program operations

s VersatileIO control

— Device generates output voltages and tolerates data

input voltages on the DQ input/ouputs as determined

by the voltage on VIO

s High performance

— Access times as fast as 90 ns

s Manufactured on 0.23 µm process technology

s CFI (Common Flash Interface) compliant

— Provides device-specific information to the system,

allowing host software to easily reconfigure for

different Flash devices

s SecSi (Secured Silicon) Sector region

— 128-word sector for permanent, secure identification

through an 8-word random Electronic Serial Number

— May be programmed and locked at the factory or by

the customer

— Accessible through a command sequence

s 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

s Flexible sector architecture

— One hundred twenty-eight 32 Kword sectors

s Sector Protection

— A hardware method to lock a sector to prevent

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

s 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

s Compatibility with JEDEC standards

— Pinout and software compatible with single-power

supply Flash

— Superior inadvertent write protection

s Minimum 1 million erase cycle guarantee per sector

s 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)

s Erase Suspend/Erase Resume

— Suspends an erase operation to read data from, or

program data to, a sect27

— or that is not being erased, then resumes the erase

operation

s Data# Polling and toggle bits

— Provides a software method of detecting program or

erase operation completion

s Unlock Bypass Program command

— Reduces overall programming time when issuing

multiple program command sequences

s Ready/Busy# pin (RY/BY#) (Am29LV640DU in FBGA

package only)

— Provides a hardware method of detecting program or

erase cycle completion

s Hardware reset pin (RESET#)

— Hardware method to reset the device for reading array

data

s WP# pin (Am29LV641DH/DL in TSOP,

Am29LV640DH/DL in SSOP only)

— At VIL, protects the first or last 32 Kword sector,

regardless of sector protect/unprotect status

— At VIH, allows removal of sector protection

— An internal pull up to VCC is provided

s ACC pin

— Accelerates programming time for higher throughput

during system production

s Program and Erase Performance (VHH not applied to

the ACC input pin)

— Word program time: 11 µs typical

— Sector erase time: 0.9 s typical for each 32 Kword

sector
