F59L8G81XA-25BG2Y

The F59L8G81XA-25BG2Y is an 8 Gbit Single-Level Cell (SLC) NAND Flash memory organized as 1G × 8. Designed for parallel asynchronous operation, the device implements an 8-bit multiplexed data bus and standard control signals for command, address and data transfer.

This commercial-grade, non-volatile Flash memory operates from 2.7 V to 3.6 V and is offered in a 63-ball BGA surface-mount package. It targets designs requiring reliable SLC NAND storage with ONFI 1.0 protocol compatibility and industry-standard pinout behavior for density scaling.

Key Features

• Memory Architecture  8.59 Gbit SLC NAND organized as 1G × 8 with device size of 4096 blocks and two planes of 2048 blocks per plane.
• Page and Block Organization  Page size is 4,320 bytes (4,096 + 224 spare); block size is 64 pages (256K + 14K bytes).
• Performance  Asynchronous I/O with RC/ WC speed grade 25 ns; typical array timings include read page 25 µs, program page 200 µs (typical) and erase block 3 ms (typical).
• Interface and Protocol  Parallel 8-bit multiplexed I/O with standard control signals (CE#, CLE, ALE, WE#, RE#) and ONFI 1.0-compliant command set.
• Advanced Command and Data Modes  Supports program page cache mode, read page cache mode, one-time programmable (OTP) mode, two-plane commands and multi-die (LUN) operations.
• Device Management and Signals  Includes R/B# ready/busy status, WP# hardware write-protect for entire device, RESET (FFh) required as first command after power-on, and internal operation status byte for software detection.
• Reliability  Endurance rated to 60,000 program/erase cycles with data retention compliant to JESD47G qualification guidance (see qualification report).
• Power  Operating VCC range 2.7 V to 3.6 V for 3.3 V system compatibility.
• Package and Mounting  Surface-mount 63-ball BGA (BGA-63) package, commercial operating temperature 0°C to +70°C, RoHS compliant.

Typical Applications

• Commercial embedded storage  Non-volatile data and file storage in systems operating within the commercial temperature range (0°C to +70°C).
• Firmware and code storage  Storage of firmware, boot code and system images using SLC NAND for endurance and reliable program/erase cycles.
• Scalable density designs  Systems that may be upgraded to higher density parts later benefit from the standard pinout, which enables migration without board redesign.

Unique Advantages

• Single-Level Cell reliability: SLC technology and a 60,000 program/erase cycle endurance provide robust write/erase longevity for critical data storage.
• ONFI 1.0 compatibility: Standard ONFI protocol support and a standard pinout simplify integration and support interoperability with ONFI-aware controllers.
• Performance-balanced array timings: Typical read, program and erase times (25 µs read page, 200 µs program page, 3 ms erase block) give predictable latency for embedded storage operations.
• Flexible command set: Cache program/read modes, OTP, two-plane and multi-die operations offer options to optimize throughput and storage management.
• Hardware status and protection signals: R/B# and WP# provide hardware-level operation monitoring and write protection; the operation status byte supports software-level completion and pass/fail checks.
• Commercial temperature and RoHS compliance: 0°C to +70°C operating range and RoHS-compliant manufacturing meet common commercial deployment and regulatory requirements.
