1 / 106 page Order Number: 251902, Revision: 009 April 2005 Intel StrataFlash® Wireless Memory (L18) 28F640L18, 28F128L18, 28F256L18 Datasheet Product Features The Intel StrataFlash ® wireless memory (L18) device is the latest generation of Intel StrataFlash ® memory devices featuring flexible, multiple-partition, dual operation. It provides high performance synchronous-burst read mode and asynchronous read mode using 1.8 V low- voltage, multi-level cell (MLC) technology. The multiple-partition architecture enables background programming or erasing to occur in one partition while code execution or data reads take place in another partition. This dual-operation architecture also allows a system to interleave code operations while program and erase operations take place in the background. The 8-Mbit or 16-Mbit partitions allow system designers to choose the size of the code and data segments. The L18 wireless memory device is manufactured using Intel 0.13 µm ETOX™ VIII process technology. It is available in industry- standard chip scale packaging. ■ High performance Read-While-Write/Erase — 85 ns initial access — 54 MHz with zero wait state, 14 ns clock-to- data output synchronous-burst mode — 25 ns asynchronous-page mode — 4-, 8-, 16-, and continuous-word burst mode — Burst suspend — Programmable WAIT configuration — Buffered Enhanced Factory Programming (BEFP) at 5 µs/byte (Typ) — 1.8 V low-power buffered programming at 7 µs/byte (Typ) ■ Architecture — Asymmetrically-blocked architecture — Multiple 8-Mbit partitions: 64-Mbit and 128- Mbit devices — Multiple 16-Mbit partitions: 256-Mbit devices — Four 16-Kword parameter blocks: top or bottom configurations — 64-Kword main blocks — Dual-operation: Read-While-Write (RWW) or Read-While-Erase (RWE) — Status Register for partition and device status ■ Power —VCC (core) = 1.7 V - 2.0 V —VCCQ (I/O) = 1.35 V - 2.0 V, 1.7 V - 2.0 V — Standby current: 30 µA (Typ) for 256-Mbit — 4-Word synchronous read current: 15 mA (Typ) at 54 MHz — Automatic Power Savings mode ■ Security — OTP space: • 64 unique factory device identifier bits • 64 user-programmable OTP bits • Additional 2048 user-programmable OTP bits — Absolute write protection: VPP = GND — Power-transition erase/program lockout — Individual zero-latency block locking — Individual block lock-down ■ Software — 20 µs (Typ) program suspend — 20 µs (Typ) erase suspend — Intel® Flash Data Integrator optimized — Basic Command Set (BCS) and Extended Command Set (ECS) compatible — Common Flash Interface (CFI) capable ■ Quality and Reliability — Expanded temperature: –25° C to +85° C — Minimum 100,000 erase cycles per block — ETOX™ VIII process technology (0.13 µm) ■ Density and Packaging — 64-, 128-, and 256-Mbit density in VF BGA packages — 128/0 and 256/0 density in SCSP — 16-bit wide data bus |
