3 / 66 page Publication# 26190 Rev: C Amendment/8 Issue Date: February 1, 2007 DATA SHEET Am29LV640MT/B 64 Megabit (4 M x 16-Bit/8 M x 8-Bit) MirrorBit ™ 3.0 Volt-only Boot Sector Flash Memory DISTINCTIVE CHARACTERISTICS ARCHITECTURAL ADVANTAGES Single power supply operation — 3 V for read, erase, and program operations Manufactured on 0.23 µm MirrorBit process technology Secured Silicon Sector region — 128-word/256-byte sector for permanent, secure identification through an 8-word/16-byte random Electronic Serial Number, accessible through a command sequence — Can be programmed and locked at the factory or by the customer Flexible sector architecture — One hundred twenty-seven 32 Kword/64-Kbyte sectors — Eight 4 Kword/8 Kbyte boot sectors Compatibility with JEDEC standards — Provides pinout and software compatibility for single-power supply flash, and superior inadvertent write protection Minimum 100,000 erase cycle guarantee per sector 20-year data retention at 125 °C PERFORMANCE CHARACTERISTICS High performance — 90 ns access time — 25 ns page read times — 0.5 s typical sector erase time — 22 µs typical effective write buffer word programming time: 16-word/32-byte write buffer reduces overall programming time for multiple-word/byte updates — 4-word/8-byte page read buffer — 16-word/32-byte write buffer Low power consumption (typical values at 3.0 V, 5 MHz) — 30 mA typical active read current — 50 mA typical erase/program current — 1 µA typical standby mode current Package options — 48-pin TSOP — 63-ball Fine-pitch BGA — 64-ball Fortified BGA SOFTWARE & HARDWARE FEATURES Software features — Program Suspend & Resume: read other sectors before programming operation is completed — Erase Suspend & Resume: read/program other sectors before an erase operation is completed — Data# polling & toggle bits provide status — Unlock Bypass Program command reduces overall multiple-word programming time — CFI (Common Flash Interface) compliant: allows host system to identify and accommodate multiple flash devices Hardware features — Sector Group Protection: hardware-level method of preventing write operations within a sector group — Temporary Sector Unprotect: V ID-level method of changing code in locked sectors — WP#/ACC input: Write Protect input (WP#) protects top or bottom two sectors regardless of sector protection settings ACC (high voltage) accelerates programming time for higher throughput during system production — Hardware reset input (RESET#) resets device — Ready/Busy# output (RY/BY#) indicates program or erase cycle completion This product has been retired and is not available for designs. For new and current designs, S29GL064A supersedes Am29LV640M T/B and is the factory-recommended migration path. Please refer to the S29GL064A datasheet for specifications and ordering information.
