Targeted at industrial applications, the device offers uniform 4 Kbyte sectors, flexible program/erase options, hardware and software write protection, and a compact 16-pin SOP 300 mil package with an industrial operating temperature range of -40°C to 85°C.

Key Features

• Memory Capacity & Organization — 256 Mbit serial flash memory organized as 32M × 8 with 131,072 pages and 256 bytes per programmable page.
• Serial SPI Architecture — Supports Standard, Dual and Quad SPI modes with configurable dummy cycles and a 104 MHz clock rate for Standard, Dual and Quad data transfers.
• Uniform Sector Architecture — 8,192 uniform 4-Kbyte sectors; also grouped into 1,024 × 32-Kbyte blocks and 512 × 64-Kbyte blocks to enable single-sector, block or full-chip erase operations.
• Program / Erase Performance — Typical page program time 0.5 ms and sector erase time 40 ms (datasheet typical values); supports page programming of 1–256 bytes per operation. (Product data also lists a write cycle time of 3 ms for word/page operations.)
• High Reliability — Minimum 100K program/erase cycles per sector and 20 years data retention as specified in the datasheet.
• Write Protection & Security — Software and hardware write protection options, WP# pin support, and a lockable 3 × 512-byte OTP security sector.
• Low Power — Typical active current ~6 mA and typical power-down current ~1 µA (datasheet typical values).
• Addressing & Identification — Supports 3-byte and 4-byte address modes, Serial Flash Discoverable Parameters (SFDP), and Read Unique ID functionality.
• Package & Temperature — Surface-mount 16-pin SOP 300 mil package option with industrial temperature range −40°C to 85°C; RoHS compliant.
• Timing & Performance — Specified clock frequency 104 MHz and access time shown as 8 ns in product specifications.

Typical Applications

• Embedded Firmware Storage — Non-volatile storage for boot code and firmware in industrial controllers and appliances, with sector-level erase and write-protect features for safe updates.
• Firmware Over-The-Air / Field Updates — Dual/Quad SPI high-speed read and configurable addressing to support reliable firmware distribution and in-field updates.
• Consumer & IoT Devices — Storage for application code, calibration data and configuration parameters where low-power standby and fast read performance matter.
• Industrial Instrumentation — Robust data retention and endurance for long-term logging, calibration tables and system parameters across the −40°C to 85°C operating range.

Unique Advantages

• Flexible SPI Modes — Standard, Dual and Quad SPI support enables scalable throughput for different system bandwidth requirements.
• Uniform Sector Granularity — 4-Kbyte sectors provide fine-grained erase and update capability to reduce wear and improve update efficiency.
• Low Power Standby — Typical 1 µA power-down current minimizes standby power for battery-backed or low-power systems.
• Industrial Ready — Industrial temperature rating and RoHS-compliant packages align with long-life embedded and industrial designs.
• Built-in Protection & Security — Hardware WP# and software protection plus lockable OTP sector enable secure storage of critical data and code.
• Proven Endurance & Retention — Datasheet-specified 100K program/erase cycles and 20-year data retention support long-term product lifecycles.
