F59L4G81XB-25BCG2X

The F59L4G81XB-25BCG2X is a single-level cell (SLC) NAND Flash memory device providing 4.295 Gbit of non-volatile storage in a 512M × 8 organization. It implements an asynchronous parallel NAND interface with a highly multiplexed 8‑bit I/O bus and standard control signals for low pin-count board integration.

This device is designed for applications requiring robust SLC endurance, flexible voltage operation, and board-level compactness, delivered in a 67‑ball BGA package and specified for commercial temperature operation (0 °C to 70 °C).

Key Features

• Memory Core 4.295 Gbit capacity organized as 512M × 8, single-level cell (SLC) NAND Flash for non-volatile data storage.
• ONFI and Command Support ONFI 1.0-compliant command set with advanced features such as program/read cache modes, SET FEATURE support, and standard NAND protocol commands.
• Performance Asynchronous access with RC/WC = 25 ns and 20 ns access parameter; read page times of up to 25 µs (ON‑die ECC disabled) and up to 115 µs (ON‑die ECC enabled).
• Program & Erase Timing Typical program page time 200 µs (with ON‑die ECC disabled) and 240 µs (with ON‑die ECC enabled); typical erase block time 2 ms.
• Reliability & Endurance Endurance rated to 100,000 program/erase cycles; data retention compliant with JESD47G and uncycled retention rated at 10 years at 70 °C.
• On‑Die ECC 8‑bit internal ECC is available (disabled by default) and can be toggled via the SET FEATURE command; block 0 shipped with ECC enabled.
• Memory Organization & Capacity Details Page size 4,352 bytes (4,096 + 256 spare), block size 64 pages, single plane.
• Interface & Control Signals Multiplexed I/O (I/O0–I/O7) with CE#, CLE, ALE, WE#, RE#, R/B#, and WP# for hardware write-protect and ready/busy status monitoring.
• Power Nominal 3.3 V operation with supported VCC range 2.7 V to 3.6 V for flexible system integration.
• Package & Temperature 67‑ball BGA (BGA‑67) surface-mount package; commercial operating temperature range 0 °C to 70 °C. RoHS compliant.

Typical Applications

• Embedded non-volatile storage Use as onboard flash storage where SLC endurance and reliable data retention are required.
• Board-level mass storage Compact 67‑ball BGA package suited to PCB designs that need high-density NAND in a small footprint.
• Systems requiring ECC control Designs that leverage on‑die ECC or host-managed ECC can use the device’s togglable 8‑bit ECC feature and SET FEATURE support.

Unique Advantages

• High endurance: 100,000 program/erase cycles provide predictable lifecycle performance for write-intensive applications.
• Flexible voltage operation: 2.7 V–3.6 V supply range with 3.3 V nominal simplifies integration across different system power rails.
• Configurable ECC: Internal 8‑bit ECC can be enabled or disabled via SET FEATURE, allowing designers to choose between device-managed or host-managed error management.
• Standardized NAND interface: ONFI 1.0 compliance and a low pin-count, multiplexed 8‑bit bus support straightforward migration and board reuse across densities.
• Compact board footprint: 67‑ball BGA (BGA‑67) package enables high-density placement while maintaining surface-mount assembly compatibility.
• Validated data retention: JESD47G-compliant data retention and 10‑year uncycled retention at 70 °C provide long-term storage assurances.
