Key Features

• Memory — 64 M-bit (8,192 KByte) density with 32,768 pages and 256 bytes per programmable page for granular data and code storage.
• Interface — SPI compatible Serial Interface supporting Standard, Dual and Quad SPI modes (CLK, CS#, DI/DO, DQ₂/DQ₃) and SPI Modes 0 and 3 for flexible system integration.
• High Performance Read — Fast read capability up to 104 MHz in Standard and Dual SPI; configurable dummy cycles to tune throughput versus latency.
• Program & Erase — Typical page program time 0.5 ms; sector erase 40 ms typical; half-block and block erase times of 200 ms and 300 ms typical respectively; full chip erase typical 32 seconds.
• Power — Low-power operation with typical active current around 3.5 mA and typical power-down current of 1 µA to support energy-conscious designs.
• Protection & Security — Software and hardware write protection, WP# pin support, lockable 512-byte OTP security sector and Read Unique ID for device identification.
• Reliability — Minimum 100K program/erase endurance per sector and 20-year data retention for long-term reliability.
• Memory Architecture — Uniform sector architecture with 2,048 × 4-Kbyte sectors, 256 × 32-Kbyte blocks and 128 × 64-Kbyte blocks enabling fine-grained erase and update.
• Package & Temperature — Available in 8-pin SOP 200mil package (surface mount) and rated for industrial temperature range (–40 °C to 85 °C). RoHS compliant.

Typical Applications

• Embedded firmware storage — Fast 104 MHz read and page program/erase characteristics enable quick boot and reliable firmware updates in embedded controllers.
• Industrial control — Industrial temperature rating (–40 °C to 85 °C) and robust endurance support long-term program and data retention in automation and control systems.
• Field upgrade and fail-safe systems — Sector-level erase and software/hardware write protection allow targeted updates and protection of critical code regions during field firmware updates.
• Communications and networking equipment — High read throughput and multi-I/O SPI modes (Dual/Quad) improve image and code transfer rates for devices requiring frequent reads.

Unique Advantages

• Fast serial reads at 104 MHz — Reduces boot and read latency for time-sensitive applications.
• Flexible SPI modes — Standard, Dual and Quad operation provide designers with options to balance pin usage and throughput.
• Fine-grained memory control — 4 KB uniform sectors and multiple block sizes enable targeted erase/program for efficient in-field updates and minimal wear.
• Low-power standby — µA-level power-down current supports battery-backed and low-power systems.
• Industrial-grade endurance and retention — 100K program/erase cycles and 20-year data retention give confidence for long-life deployments.
• Hardware and software protection — Multiple protection mechanisms (WP# pin, software protection, OTP lock) help secure critical code and data.
