• Page & Block Sizes x8 page size: (2K + 64) bytes per page; block size for x8 devices: (128K + 4K) bytes.
• Performance -45 speed grade: 45 ns cycle time per byte in page-mode reads. Typical page program time ~300 µs and typical block erase time ~4 ms. Random read: 25 µs (max) for specified operations in the datasheet.
• Program / Erase Endurance & Retention Endurance: 100K program/erase cycles. Data retention: 10 years.
• Power Single 1.8V VCC operation (specified range 1.7 V to 1.95 V) for low-voltage system integration.
• Interface & Modes Parallel command/address/data multiplexed I/O port with cache program/read, copy-back, EDO mode, and NOP support for pipelined operations and improved throughput.
• System Reliability & Protection Hardware data protection including program/erase lockout during power transitions, bad-block protect, and One-Time-Program (OTP) operation. ECC requirement for x8: 4-bit per 512-byte.
• Package & Grade Surface-mount 48-pin TSOPI package; commercial grade with operating temperature 0 °C to 70 °C and RoHS-compliant construction.

Typical Applications

• Solid-state mass storage — SLC architecture and block-oriented erase/program operations suit mass storage applications requiring endurance and long data retention.
• Boot and firmware storage for embedded systems — Built-in Boot-from-NAND support and automatic memory download enable reliable system boot and firmware update workflows.
• Firmware image storage and secure one-time data — OTP operation and spare-area organization support firmware images and one-time programming scenarios.
• Commercial consumer and industrial devices — Low-voltage 1.8V operation and a compact 48-pin TSOPI package enable integration into space-constrained commercial designs within the 0 °C to 70 °C range.

Unique Advantages

• SLC endurance and retention: 100K program/erase cycles and 10-year data retention support long-lived storage requirements.
• Low-voltage operation: 1.8V supply range (1.7–1.95 V) enables reduced power system designs and compatibility with low-voltage platforms.
• High-efficiency program/read features: Cache program/read and copy-back operations allow pipelined programming and improved throughput for sustained data transfers.
• Robust data-protection features: Hardware program/erase lockout during power transitions, bad-block protection and specified ECC requirements help maintain data integrity.
• Compact commercial package: 48-pin TSOPI surface-mount package for compact board layouts and straightforward assembly.
