• Performance: Asynchronous I/O performance with 1/RC/3/RC timing at 25 ns, typical read page latency 25 µs, typical program page 200 µs, and typical erase block 2 ms; access time listed at 20 ns.
• Interface & Protocol: Parallel 8-bit I/O bus using standard NAND control signals (CE#, CLE, ALE, WE#, RE#), Ready/Busy# (R/B#), WP# and ONFI 1.0-compliant command set.
• Reliability & Endurance: Endurance rated to 100,000 program/erase cycles with JESD47G-compliant data retention and uncycled data retention of 10 years.
• Power: Wide supply range 2.7 V–3.6 V (3.3 V nominal) for compatibility with common commercial system rails.
• Package & Mounting: 63-ball BGA (BGA-63) surface-mount package, commercial grade operating temperature 0 °C to +70 °C.
• Device Management & Security: Supports permanent block locking (blocks 47:0), one-time programmable (OTP) mode, block lock, read unique ID, programmable drive strength, two-plane commands (with ECC off), and internal data move operations within a plane.

Typical Applications

• Commercial Embedded Systems: Provides non-volatile program and data storage for commercial embedded designs requiring SLC endurance and retention.
• Board-level Storage Modules: Suited for integration on system PCBs where a compact BGA package and parallel 8-bit interface reduce board footprint and simplify routing.
• Firmware and Code Storage: Designed for storing firmware images and boot code with reliable program/erase endurance and OTP/block-lock options for secure code regions.

Unique Advantages

• SLC Endurance: 100,000 program/erase cycles deliver predictable durability for frequent program/erase use cases.
