Designed for embedded and industrial storage applications, this device combines SLC endurance and retention characteristics with ONFI 1.0-compliant command support, on-die ECC options, and a wide operating voltage and temperature window for robust system integration.

Key Features

• Memory & Organization  4.295 Gbit capacity organized as 512M × 8 with a page size of 4,352 bytes (4,096 + 256) and 64-page blocks.
• Technology  Single-level cell (SLC) NAND Flash for non-volatile data storage and endurance-focused operation.
• Performance  Asynchronous I/O with RC/WC timing of 25 ns (ordering speed grade) and documented read/program/erase timings (read page: 115 µs max with on-die ECC enabled / 25 µs max with on-die ECC disabled; program page: 200 µs typical with ECC disabled, 240 µs typical with ECC enabled; erase block: 2 ms typical).
• Interface & Command Set  Parallel NAND interface using a highly multiplexed 8-bit I/O bus with standard control signals (CE#, CLE, ALE, WE#, RE#) and ONFI 1.0-compliant command set.
• Power & Voltage  Operates across a wide supply range: Vcc 2.7–3.6 V (nominal 3.3 V).
• Reliability & Endurance  Endurance rated to 100,000 program/erase cycles; data retention and qualification follow JEDEC guidelines with uncycled data retention specified as 10 years at 70°C.
• System Signals & Protection  Hardware status and protection signals including R/B# (Ready/Busy), WP# (write protect entire device) and RESET required after power-on. Internal 8-bit ECC is available and can be enabled or disabled via SET FEATURE.
• Package & Temperature  63-ball BGA (surface mount) in an industrial grade device with an operating temperature range of −40°C to 85°C.
• Advanced Features  Support for program/read cache modes, permanent block locking, one-time programmable (OTP) mode, programmable drive strength, read unique ID, and internal data-move operations within a plane.

Typical Applications

• Industrial Storage Systems  Non-volatile SLC storage for factory automation and control systems where endurance and wide-temperature operation are required.
• Embedded Controllers  Local code and data storage for embedded platforms that require an asynchronous parallel NAND interface and program/erase durability.
• Data Logging & Instrumentation  Long-term data retention and high P/E cycle endurance make this device suited for continuous logging and measurement equipment.
• Networking & Communication Equipment  Reliable firmware and configuration storage in systems that benefit from JEDEC-qualified memory and on-die ECC options.

Unique Advantages

• Industrial-grade endurance: 100,000 program/erase cycles support sustained write-intensive use cases in harsh environments.
• Wide operating window: Vcc 2.7–3.6 V and −40°C to 85°C operation simplify deployment across diverse industrial platforms.
• SLC reliability and retention: Single-level cell design plus uncycled data retention of 10 years at 70°C provides predictable long-term storage behavior.
• ONFI 1.0 compatibility: Standardized NAND command set and asynchronous interface reduce integration effort and enable straightforward upgrades to compatible devices.
• Flexible error management: Internal 8-bit ECC can be enabled or disabled via SET FEATURE to match system-level ECC strategies.
• Space-efficient package: 63-ball BGA surface-mount packaging delivers a compact footprint for board-level integration.
