AM29LV640DU-90RWHI

■ Single power supply operation
— 3.0 to 3.6 volt read, erase, and program operations
■ VersatileIO™ control
— Device generates output voltages and tolerates data input voltages on the DQ input/outputs as determined by the voltage on VIO
■ 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,allowing host software to easily reconfigure for different Flash devices
■ 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
■ 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 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
■ 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

■ Compatibility with JEDEC standards
— Pinout and software compatible with single-power supply Flash
— 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 program data to, a sect27
— or that is not being erased, then resumes the erase operation
■ Data# Polling and toggle bits
— Provides a software method of detecting program or erase operation completion
■ Unlock Bypass Program command
— Reduces overall programming time when issuing multiple program command sequences
■ Ready/Busy# pin (RY/BY#) (Am29LV640DU in FBGA package only)
— Provides a hardware method of detecting program or erase cycle completion
■ Hardware reset pin (RESET#)
— Hardware method to reset the device for reading array data
■ 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
■ ACC pin
— Accelerates programming time for higher throughput during system production
■ 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
