Continuity of Specifications There is no change to this datasheet as a result of offering the device as a Spansion product. Any changes that have been made are the result of normal datasheet improvement and are noted in the document revision summary, where supported. Future routine revisions will occur when appropriate, and changes will be noted in a revision summary. Continuity of Ordering Part Numbers AMD and Fujitsu continue to support existing part numbers beginning with “Am” and “MBM”. To order these products, please use only the Ordering Part Numbers listed in this document. For More Information Please contact your local AMD or Fujitsu sales office for additional information about Spansion memory solutions.

Am29DL640H 64 Megabit (8 M x 8-Bit/4 M x 16-Bit) CMOS 3.0 Volt-only, Simultaneous Read/Write Flash Memory DISTINCTIVE CHARACTERISTICS ARCHITECTURAL ADVANTAGES ■ Simultaneous Read/Write operations — Data can be continuously read from one bank while executing erase/program functions in another bank. — Zero latency between read and write operations ■ Flexible Bank architecture — Read may occur in any of the three banks not being written or erased. — Four banks may be grouped by customer to achieve desired bank divisions. TM ■ Ultra low power consumption (typical values) — 2 mA active read current at 1 MHz — 10 mA active read current at 5 MHz — 200 nA in standby or automatic sleep mode ■ Minimum 1 million erase cycles guaranteed per sector ■ 20 year data retention at 125°C — Reliable operation for the life of the system SOFTWARE FEATURES ■ Data Management Software (DMS) — AMD-supplied software manages data programming, enabling EEPROM emulation ■ Supports Common Flash Memory Interface (CFI) ■ Erase Suspend/Erase Resume — Suspends erase operations to read data from, or program data to, a sector that is not being erased, then resumes the erase operation. ■ Data# Polling and Toggle Bits — Provides a software method of detecting the status of program or erase cycles ■ Unlock Bypass Program command — Reduces overall programming time when issuing multiple program command sequences ■ Boot Sectors — Top and bottom bo.
