3 / 57 page This Data Sheet states AMD’s current technical specifications regarding the Products described herein. This Data Sheet may be revised by subsequent versions or modifications due to changes in technical specifications. Publication# 23579 Rev: C Amendment/8 Issue Date: December 14, 2005 Refer to AMD’s Website (www.amd.com) for the latest information. Am29LV320D 32 Megabit (4 M x 8-Bit/2 M x 16-Bit) CMOS 3.0 Volt-only, Boot Sector Flash Memory DISTINCTIVE CHARACTERISTICS ARCHITECTURAL ADVANTAGES Secured Silicon — 64 Kbyte Sector Size; Replacement/substitute devices (such as Mirrorbit ™) have 256 bytes. — Factory locked and identifiable: 16 bytes (8 words) 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 programmed once and then permanently locked after being shipped from AMD Zero Power Operation — Sophisticated power management circuits reduce power consumed during inactive periods to nearly zero. Package options — 48-pin TSOP —48-ball FBGA Sector Architecture — Eight 8 Kbyte sectors — Sixty-three 64 Kbyte sectors 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 90 ns — Program time: 7µs/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 erase cycles guaranteed per sector 20 Year data retention at 125°C — Reliable operation for the life of the system SOFTWARE FEATURES Supports Common Flash Memory Interface (CFI) Erase Suspend/Erase Resume — Suspends erase operations to allow programming in non-suspended sectors 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 provides accelerated program times 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, S29AL032D supersedes Am29LV320D and is the factory-recommended migration path. Please refer to the S29AL032D datasheet for specifications and ordering information.
