Key Features

• Memory Capacity & Organization – 1.074 Gbit capacity arranged as 128M×8 with spare area; page size (2K + 64) bytes and block size (128K + 4K) bytes.
• NAND SLC Technology – 1 bit per memory cell (SLC) architecture providing endurance and data retention suitable for demanding write/erase cycles.
• Performance – Specified access time of 20 ns and supports serial/page read at 25 ns cycle time per byte; write/program timing includes a write cycle time (word/page) of 350 µs (specifications) and a typical program time noted as 400 µs in the datasheet.
• Endurance & Retention – Endurance rated at 100K program/erase cycles with data retention of 10 years.
• Interface & Features – Parallel command/address/data multiplexed I/O port with cache program/read, copy-back operation, OTP operation, automatic page 0 read at power-up and boot-from-NAND support.
• Power – Single supply operation across 2.7 V to 3.6 V (nominal 3.3 V).
• Automotive Qualification & Temperature – Grade: Automotive with AEC-Q100 qualification and operating temperature range of −40 °C to 105 °C.
• Package & Mounting – Surface-mount TSOPI package, 48-pin (TSOPI-48) form factor for board-level integration.
• Reliability Supports – ECC requirement of 1 bit per 528 bytes and hardware data protection features, including program/erase lockout during power transitions and bad-block protection.

Typical Applications

• Automotive Systems – Non-volatile storage for infotainment, telematics and control modules where AEC‑Q100 qualification and extended temperature operation are required.
• Embedded Code & Boot Storage – Supports boot-from-NAND and automatic read-at-power-up for system boot code and firmware storage.
• Industrial Data Logging – Reliable SLC endurance and long retention for field data logging and configuration storage in industrial equipment.
• Solid-State Mass Storage – NAND architecture, cache and copy-back features optimize throughput for streaming or large-file write operations in embedded storage applications.

Unique Advantages

• Automotive‑grade Reliability – AEC‑Q100 qualification and −40 °C to 105 °C operating range make the device suitable for demanding vehicle environments.
• High Endurance – 100K program/erase cycles provide longevity for applications with frequent update requirements.
• Deterministic Retention – 10‑year data retention supports long-term storage of firmware and critical data.
• Flexible Page/Block Management – Page program (2K+64 bytes), block erase segmentation, copy-back and bad-block-protect simplify defect management and preserve valid data during erase cycles.
• Fast Read and Program Throughput – 20 ns access specification with cache read/program and 25 ns serial read support help accelerate streaming and sequential page operations.
• System-Level Safety Features – Hardware protection against program/erase during power transitions and ECC requirement guidance enable robust system designs.
