W29N01HVSANF – SLC NAND Flash – Winbond

The Winbond W29N01HVSANF is a 1Gbit (128MB) 3.3V x8 SLC NAND Flash memory in a 48-pin TSOP1 package, supporting the standard ONFI-compatible NAND interface for embedded code and data storage.

The Winbond W29N01HVSANF is a 1G-bit (138,412,032-byte) Single-Level Cell (SLC) NAND Flash memory from the W29N01HV family. Designed for embedded systems with limited space, pins, and power, it is well suited to code shadowing to RAM, solid-state storage, and storing media data such as voice, video, text, and photos. The device operates from a single 2.7V to 3.6V supply and communicates over the standard multiplexed 8-bit (x8) NAND interface, making it compatible with equivalent industry-standard SLC NAND devices.

The memory array is organized into 1,024 erasable blocks of 135,168 bytes each. Every block consists of 64 programmable pages of 2,112 bytes (2,048 bytes main area + 64 bytes spare area), with the spare area typically used for error management.
