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 V IO 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 V IL, protects the first or last 32 Kword sector, regardless of sector protect/unprotect status — At V IH, allows removal of sector protection — An internal pull up to V CC is provided s ACC pin — Accelerates programming time for higher throughput during system production s Program and Erase Performance (V HH 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 |
