3 / 55 page ADVANCE INFORMATION This document contains information on a product under development at Advance Micro Devices. The information is intended to help you evaluate this product. Do not design in the product without contacting the factory. AMD reserves the right to change or discontinue work on this proposed product without notice. Publication# 25295 Rev: A Amendment/+3 Issue Date: June 14, 2005 Refer to AMD’s Website (www.amd.com) for the latest information. Am29LV641G 64 Megabit (4 M x 16-Bit) CMOS 3.0 Volt-only Uniform Sector Flash Memory with VersatileI/O ™ Control DISTINCTIVE CHARACTERISTICS ARCHITECTURAL ADVANTAGES ■ Single power supply operation — 2.7 to 3.6 volt read, erase, and program operations ■ 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 ■ VersatileI/O ™ control — Device generates data output voltages and tolerates data input voltages as determined by the voltage on the V IO pin ■ Manufactured on 0.18 µm process technology ■ Flexible sector architecture — One hundred twenty-eight 32 Kword sectors ■ Compatibility with JEDEC standards — Pinout and software compatible with single-power supply Flash standard ■ Package options — 48-pin TSOP and Reverse TSOP (LV641GH/L only) — 63-ball Fine-Pitch BGA (LV640GU only) — 64-ball Fortified BGA (LV640GU only) ■ Minimum 1 million erase cycle guarantee per sector ■ 20-year data retention at 125 °C PERFORMANCE CHARCTERISTICS ■ High performance — Access time ratings as fast as 55 ns ■ 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 ■ Program and erase performance (V HH not applied to the ACC input pin) — Word program time: 7 µs typical — Sector erase time: 0.6 s typical for each 32 Kword sector SOFTWARE AND HARDWARE FEATURES ■ Hardware features — Hardware reset input (RESET#): resets device for new operation — WP# input: protects first or last 32 Kword sector regardless of sector protection settings (LV641GH/L only) — ACC input: Accelerates programming time for higher throughput during system production ■ Software features — Program Suspend & Resume: read other sectors before programming operation is completed — Sector Group Protection: V CC-level method of preventing program or erase operations within a sector — Temporary Sector Group Unprotect: V ID-level method of changing in previously locked sectors — CFI (Common Flash Interface) compliant: allows host system to identify and accommodate multiple flash devices — Erase Suspend/Erase Resume: read/program other sectors before an erase operation is complete — Data# Polling and toggle bits provide erase and programming operation status — Unlock Bypass Program command reduces overall multiple-word programming time This product has been retired and is not recommended for designs. For new and current designs, S29GL064A supersedes Am29LV641G and is the factory-recommended migration path. Please refer to the S29GL064A datasheet for specifications and ordering information.
