NAND256W4A0AN6E

The NAND256W4A0AN6E is a 256 Mbit non-volatile NAND flash memory organized as 16M × 16 with a parallel (x16) interface in a 48‑TSOP footprint. It targets mass-storage and embedded boot applications that require parallel NAND architecture, 3.0 V supply operation, and commercial temperature operation.

Built on NAND flash technology, the device offers block erase and page program/read operations, on‑chip data protection features and development support items documented in the product datasheet.

Key Features

• Memory Architecture — 256 Mbit NAND flash organized as 16M × 16 (x16 bus width) with page and block structure suitable for mass storage implementations.
• Interface — Parallel NAND interface (x16) with multiplexed address/data signals and pinout compatibility across densities.
• Performance — Sequential access timing down to 50 ns (min); random page access up to 12 μs (max); typical page program time ~200 μs and typical block erase time ~2 ms as documented.
• Supply and Timing — 3.0 V device operating range VDD = 2.7 V to 3.6 V; write/read timing including 50 ns word/page write-cycle timing available.
• Endurance and Retention — Documented for 100,000 program/erase cycles and 10 years data retention in the datasheet.
• Data Protection & Reliability — Hardware data protection during power transitions, status register and electronic signature features, and built‑in bad block management concepts described in the datasheet.
• Advanced Flash Functions — Supports copy‑back program mode (fast page copy without external buffering) and optional automatic page 0 read at power‑up for boot support.
• Package & Temperature — Supplied in a 48‑TSOP package (0.724" / 18.40 mm width) and specified for operation from −40 °C to +85 °C (TA).
• Development Resources — Documentation references ECC software/hardware models, bad block management and wear leveling algorithms, and PC demo boards for development and evaluation.

Typical Applications

• Mass storage solutions — Use in cost‑effective NAND flash storage arrays where a parallel x16 interface and block/page management are required.
• Embedded boot and firmware storage — Automatic page‑0 read at power‑up and boot support options enable system boot and automatic memory download workflows.
• Development and evaluation — Designed for use with provided demo boards, ECC models and reference software for firmware and file‑system development.

Unique Advantages

• Parallel x16 organization: Enables 16‑bit data transfers for systems designed around parallel NAND interfaces, matching legacy and embedded controller requirements.
• Wide VDD operating range: 2.7 V to 3.6 V support simplifies integration into 3.0 V systems.
• Documented endurance and retention: 100,000 program/erase cycles and 10 years data retention provide predictable lifecycle planning for storage applications.
• Fast internal operations: Sequential access to 50 ns (min), page program ~200 μs (typ) and block erase ~2 ms (typ) support responsive read/program/erase sequences.
• On‑chip functional support: Copy‑back program mode, status register and electronic signature options reduce external buffering and simplify firmware handling of flash operations.
• Development support ecosystem: Provided ECC models, bad block management and demo board references accelerate integration and validation activities.
