Overview of F59L2G81XA-25TIG2B – SLC NAND Flash, 2Gbit (256M x 8), Industrial

The F59L2G81XA-25TIG2B is a 2 Gbit single-level cell (SLC) NAND flash memory organized as 256M × 8. Designed for industrial applications, it delivers a parallel 8-bit asynchronous interface in a compact 48-pin TSOPI surface-mount package and operates from a 2.7 V to 3.6 V supply.

With JEDEC qualification and a wide operating temperature range of −40 °C to +85 °C, this device targets embedded systems and industrial storage where endurance, data retention and a standardized NAND interface are required.

Key Features

  • Memory Organization 2.147 Gbit device organized as 256M × 8 with 2 planes × 1,024 blocks per plane and a device total of 2,048 blocks.
  • Page and Block Geometry 2,176-byte page format (2,048 bytes + 128 bytes) and 64 pages per block (128 KB + 8 KB per block).
  • Performance Asynchronous I/O with typical array timing: read page ~25 µs, program page ~200 µs (typical), and erase block ~2 ms (typical). Order code denotes 25 ns timing grade for command/address cycle timing.
  • Interface and Protocol Standard 8-bit multiplexed parallel interface with control signals CE#, CLE, ALE, WE#, RE#, and hardware status via R/B#. ONFI 1.0-compliant command set and asynchronous NAND protocol.
  • Reliability and Endurance Designed for long-term data retention (JESD47G-compliant) and rated for 100,000 program/erase cycles with uncycled data retention of 10 years.
  • Advanced Command and Data Management Supports program page cache mode, read page cache mode, permanent block locking (blocks 47:0), one-time programmable (OTP) mode, read unique ID, and internal data move within a plane.
  • System Integration and Control Ready/Busy# (R/B#) and operation status byte provide hardware and software methods to detect operation completion and write-protect status; RESET (FFh) required after power-on.
  • Power and Packaging 3.3 V nominal operation (2.7 V to 3.6 V range) in a surface-mount 48-pin TSOPI (TSOPI-48) package suitable for board-level flash implementations.
  • Industrial Grade Operating temperature range of −40 °C to +85 °C and RoHS compliance for industrial deployments.

Typical Applications

  • Industrial Automation Reliable non-volatile storage for configuration, logging and firmware in controllers and PLCs across wide temperature ranges.
  • Embedded Storage On-board code and data storage for embedded systems that require SLC endurance and extended data retention.
  • Networking and Communications Equipment Firmware and parameter storage in industrial networking devices where standardized NAND interfaces and hardware status signals simplify integration.
  • Test & Measurement Instruments Non-volatile data and firmware storage for instrumentation that demands durable program/erase cycles and JEDEC-qualified memory behavior.

Unique Advantages

  • High Endurance: 100,000 program/erase cycles support frequent updates and long lifecycle operation in fielded equipment.
  • Long-Term Data Retention: JESD47G-compliant retention and 10-year uncycled retention provide confidence for archived data and firmware.
  • Standardized ONFI Interface: ONFI 1.0 compliance and an 8-bit multiplexed bus enable straightforward integration with existing NAND controllers and legacy designs.
  • Industrial Temperature Range: −40 °C to +85 °C rating ensures operation in harsh environments common to industrial and infrastructure applications.
  • Flexible System Control: Hardware signals (R/B#, WP#) and an operation status byte allow both hardware and software-level monitoring of device operations.
  • Compact Board-Level Package: TSOPI-48 surface-mount package offers a low pin-count footprint while maintaining a consistent pinout across densities for future upgrades.
  • Regulatory and Environmental Compliance: JEDEC qualification and RoHS compliance support regulatory and manufacturing requirements.
