Am29DL322D/323D/324D 32 Megabit (4 M x 8-Bit/2 M x 16-Bit) CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory DISTINCTIVE CHARACTERISTICS ARCHITECTURAL ADVANTAGES ■ Simultaneous Read/Write operations — Data can be continuously read from one bank while executing erase/program functions in other bank. — Zero latency between read and write operations ■ Multiple bank architectures — Three devices available with different bank sizes (refer to Table 3) ■ SecSiTM (Secured Silicon) Sector — Current version of device has 64 Kbytes; future versions will have 256 bytes — Factory locked and identifiable: 16 bytes available for secure, random factory Electronic Serial Number; verifiable as factory locked through autoselect function. ExpressFlash option allows entire sector to be available for factory-secured data — Customer lockable: Can be read, programmed, or erased just like other sectors. Once locked, data cannot be changed ■ Zero Power Operation — Sophisticated power management circuits reduce power consumed during inactive periods to nearly zero. ■ Package options —63-ball FBGA — 48-pin TSOP ■ Top or bottom boot block ■ Manufactured on 0.23 µm process technology ■ Compatible with JEDEC standards — Pinout and software compatible with single-power-supply flash standard PERFORMANCE CHARACTERISTICS ■ High performance — Access time as fast 70 ns — Program time: 7 µs/word typical utilizing Accelerate function ■ 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 write 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 — Eases historical sector erase flash limitations ■ Supports Common Flash Memory Interface (CFI) ■ Erase Suspend/Erase Resume — Suspends erase operations to allow programming in same bank ■ 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 HARDWARE FEATURES ■ Any combination of sectors can be erased ■ Ready/Busy# output (RY/BY#) — Hardware method for detecting program or erase cycle completion ■ Hardware reset pin (RESET#) — Hardware method of resetting the internal state machine to the read mode ■ WP#/ACC input pin — Write protect (WP#) function allows protection of two outermost boot sectors, regardless of sector protect status — Acceleration (ACC) function accelerates program timing ■ Sector protection — Hardware method of locking a sector, either in-system or using programming equipment, to prevent any program or erase operation within that sector — Temporary Sector Unprotect allows changing data in protected sectors in-system This product has been retired and is not available for designs. For new and current designs involving TSOP packages, S29JL032H supersedes Am29DL32xD and is the factory-recom- mended migration path. Please refer to the S29JL032H Datasheet for specifications and ordering information. For new and current designs involving Fine-pitch BGA (FBGA) packages, S29PL032J supersedes Am29DL32xD and is the factory-recommended migration path. Please refer to the S29PL032J Datasheet for specifications and ordering information. Availability of this document is retained for reference and historical purposes only. |
