• SLC Technology Single-level cell NAND Flash for high endurance and reliable data retention; endurance rated to 100,000 program/erase cycles.
• Performance Speed grade -45 (45 ns); product specifications list an access time of 25 ns. Asynchronous I/O performance with page read/program timing examples: read page up to 170 μs (with on-die ECC enabled) and program page typ. 200 μs (ECC disabled) / 240 μs (ECC enabled).
• Interface and Commands ONFI 1.0-compliant NAND command set with asynchronous parallel x8 I/O, command/address/data multiplexing and support for program/read page cache modes.
• Power Low-voltage operation at 1.8 V (operating range 1.7 V to 1.95 V), suitable for systems using 1.8 V NAND supply rails.
• Data Integrity and Management 8-bit internal ECC (disabled by default, can be toggled via SET FEATURE); features include permanent block locking, programmable drive strength, read unique ID, and internal data move within the plane.
• Reliability & Retention JESD47G-compliant data retention with uncycled data retention specified as 10 years (24/7 at 70°C). Operation ready/busy and operation status byte for software/hardware completion detection.
• Package & Temperature Pb‑free 63-ball BGA (BGA-63) surface-mount package and industrial operating temperature range of −40 °C to 85 °C.
• Quality & Qualification JEDEC qualification and manufacturer-specified advanced command support including OTP mode and block locking.
• Compliance RoHS compliant.

Typical Applications

• Industrial Embedded Storage Industrial-grade temperature range and JEDEC-qualified SLC technology for reliable code and data storage in factory automation and control equipment.
• Firmware and Boot Storage Organized pages and blocks with program/erase endurance suitable for frequently updated firmware and boot code storage.
• Data Logging and Measurement SLC endurance and long data retention make the device suitable for industrial data logging where robust retention and repeated writes are required.
• Compact Board-Level Integration 63-ball BGA package and surface-mount mounting reduce board footprint for space-constrained embedded designs.

Unique Advantages

• Industrial Temperature Support: Supports −40 °C to 85 °C operation, enabling deployment in harsh and temperature-variable environments.
