F59L8G81XA-25TG2Y

The F59L8G81XA-25TG2Y is an 8.59 Gbit single-level cell (SLC) NAND Flash memory organized as 1G × 8 with a parallel x8 interface. Designed for non-volatile data and program storage, the device supports asynchronous I/O with ONFI 1.0 compatibility and operates from a 2.7 V to 3.6 V supply.

With features such as hardware Ready/Busy# and Write Protect (WP#) signals, multi-plane operations, and internal data-move support, the device addresses embedded storage needs where reliable, byte-addressable NAND Flash is required in a compact 48-pin TSOPI surface-mount package.

• Performance Asynchronous I/O with typical timings: access time 20 ns (spec sheet listing) and RC/ WC rated 25 ns; read page ~25 µs, program page ~200 µs (typ), erase block ~3 ms (typ).
• Interface & Commands Parallel x8 bus using standard NAND control signals (CE#, CLE, ALE, WE#, RE#) and ONFI 1.0-compliant command set with advanced features such as program/read page cache modes, two-plane commands, OTP mode, and multi-die (LUN) operations.
• System Signals Ready/Busy# (R/B#) for hardware status, WP# for device write protection, and an operation status byte for software detection of completion and pass/fail conditions.
• Reliability & Endurance Endurance rated to 60,000 program/erase cycles and data retention compliant with JESD47G (see qualification report).
• Power & Temperature Supply voltage range 2.7 V to 3.6 V; commercial operating temperature 0 °C to +70 °C.
• Package & Mounting Surface-mount TSOPI-48 package (12 mm × 20 mm body, 0.5 mm pin pitch), Pb-free option available.
• Factory & Initialization First block shipped with factory ECC; RESET (FFh) required as the first command after power-on or an alternative device initialization method can be used.

Typical Applications

• Embedded Storage Non-volatile program and data storage in embedded systems using a parallel x8 NAND interface and 3.3 V supply range.
• Firmware & Code Store Reliable SLC storage for firmware images where endurance (60,000 P/E cycles) and data retention are required.
• Consumer & Industrial Devices Local flash storage in commercial-grade electronics operating between 0 °C and +70 °C, benefiting from the TSOPI-48 surface-mount package.

Unique Advantages

• SLC Endurance: Rated to 60,000 program/erase cycles, providing robust write-cycle longevity for firmware and frequent-update storage.
• ONFI 1.0 Compliance: Standardized NAND protocol support for compatibility with ONFI-aware controllers and toolchains.
• Flexible Interface & Controls: Parallel x8 bus with CE#, CLE, ALE, WE#, RE#, R/B# and WP# signals for straightforward hardware integration and status monitoring.
• Advanced Command Support: Program/read page cache modes, two-plane commands and multi-die operations enable efficient data transfer and parallelism within the device.
• Wide Voltage Range: 2.7 V to 3.6 V supply window supports common 3.3 V system rails and tolerant operation across typical commercial designs.
• Compact Surface-Mount Package: TSOPI-48 package provides a low-pin-count footprint for board-level integration without redesign across densities.
