• SLC NAND Technology — Single-level cell architecture with endurance rated to 100,000 program/erase cycles and uncycled data retention specified at 10 years.
• Performance & Timing — Device offered in a 45 ns speed option; access time listed at 25 ns. Typical array performance: read page 30 µs, program page 200 µs (typical), erase block 2 ms (typical); asynchronous I/O with tRC/tWC noted at 30 ns.
• Interface & Command Support — 8-bit parallel I/O with standard NAND control signals (CE#, CLE, ALE, WE#, RE#) and ONFI 1.0-compliant command set including advanced features such as program/read page cache modes, two‑plane commands, OTP mode, and read unique ID.
• Power — Operates from a 1.8 V supply range (1.7 V to 1.95 V) suitable for low-voltage embedded systems.
• Package & Mounting — Available in a 48-pin TSOPI surface-mount package (TSOPI-48) with a small footprint for space-constrained PCBs.
• Industrial Grade & Qualification — Industrial operating temperature range from −40 °C to +85 °C and JEDEC qualification for robust field performance.
• Device Management & Protection — Ready/Busy# (R/B#) and operation status byte for software and hardware detection of operation completion, plus WP# for device-level write protection.

Typical Applications

• Industrial Control Systems — Non-volatile program and parameter storage that withstands −40 °C to +85 °C for factory automation and PLCs.
• Embedded Firmware & Boot Storage — Reliable SLC endurance and data retention for firmware images and boot sequences in embedded devices.
• Data Logging & Event Recording — High program/erase cycle endurance and page-level program/read performance for cyclic logging and event storage in industrial IoT nodes.

Unique Advantages

• Long Endurance: 100,000 program/erase cycles offers predictable lifetime for write-intensive industrial applications.
• Standard ONFI Interface: ONFI 1.0 compliance and an 8-bit parallel bus enable straightforward integration with existing NAND controllers and migration between densities.
• Low-Voltage Operation: 1.8 V supply (1.7 V–1.95 V) reduces system power domain complexity in low-voltage designs.
• Industrial Temperature Range: Specified −40 °C to +85 °C to meet the thermal demands of harsh environments and extended-temperature deployments.
• Compact Surface-Mount Package: TSOPI-48 package supports PCB space optimization while providing necessary control and I/O signals for asynchronous NAND operation.
• Robust Data Management: Built-in status reporting, R/B# signaling and write-protect support simplify firmware control and improve system reliability.
