F59L1G81LB-25TG2M

The F59L1G81LB-25TG2M is a 1.074 Gbit single-level cell (SLC) NAND flash device organized as 128M x 8 with spare area. It implements a parallel x8 NAND interface at a 3.3V supply range (2.7V–3.6V) and is offered in a 48‑pin TSOPI surface-mount package.

Designed for solid-state mass storage and embedded memory applications, the device combines page and block architecture, on-chip data registers and cache features, and hardware protection options to support boot and storage use cases where endurance, data retention and predictable electrical characteristics are required.

Key Features

• Memory & Organization 1.074 Gbit capacity organized as 128M × 8 with an additional spare area (4M × 8). Page size is (2K + 64) bytes and block size is (128K + 4K) bytes.
• Performance Access time specified at 20 ns; serial access 25 ns (datasheet). Page program and cache program operations are supported to improve program throughput.
• Program / Erase Timing Write cycle time (word/page) listed as 350 µs; datasheet lists typical program and erase timing details for planning programming and maintenance operations.
• Interface Parallel command/address/data multiplexed I/O port with x8 data bus for direct parallel connection in embedded designs.
• Power Nominal 3.3V operation with an input range of 2.7V to 3.6V for flexible power-supply integration.
• Reliability & Data Integrity SLC NAND cell design with endurance specified at 100K program/erase cycles and data retention of 10 years. ECC requirement indicated as 1 bit per 528 bytes.
• System & Boot Support Features include automatic page 0 read at power-up and boot-from-NAND support to simplify system boot and firmware storage.
• Package & Temperature Surface-mount TSOPI-48 package (12 mm × 20 mm, 0.5 mm pitch) and a commercial operating temperature range of 0 °C to 70 °C. RoHS compliant.

Typical Applications

• Embedded Storage Use as local non-volatile storage for firmware, file systems and application data in embedded devices that require SLC durability and retention.
• Boot Memory Supports boot-from-NAND and automatic page 0 read at power-up for systems that store boot code or initial firmware images in NAND flash.
• Solid‑State Mass Storage Suited for compact solid-state storage implementations where block/ page management and reliable P/E endurance are needed.

Unique Advantages

• SLC Endurance: Endurance rated at 100K program/erase cycles and 10 years data retention provide long-term reliability for storage and firmware applications.
• Flexible Voltage Window: 2.7V–3.6V operating range enables straightforward integration with common 3.3V system rails.
• Parallel x8 Interface: Multiplexed command/address/data I/O simplifies host interfacing in parallel NAND designs.
• Boot and Power-Up Features: Automatic page 0 read at power-up and boot-from-NAND support reduce system initialization complexity.
• Package Options: Available in a compact TSOPI-48 surface-mount package for space-constrained boards with standard pitch and board-mount processes.
