This device is designed for embedded and industrial applications that require reliable code and data storage across a wide temperature range (−40 °C to 85 °C), delivered in a surface-mount SOP package for streamlined PCB integration.

Key Features

• Memory & Organization  1.049 Mbit capacity organized as 128K × 8 with 256‑byte programmable page size and 512 pages per device.
• SPI NOR Flash Technology  Serial Peripheral Interface (SPI) NOR architecture with support for Standard, Dual and Quad SPI modes (series-level).
• High-Speed Operation  Up to 104 MHz clock rate for 1-bit, 2-bit and 4-bit data transfers, enabling fast read throughput for code and data access.
• Performance Timing  Access time 8 ns and write cycle time (word/page) specified at 3 ms in the product data.
• Flexible Erase Granularity  Uniform sector architecture with 4 Kbyte sectors, plus larger 32 Kbyte and 64 Kbyte block options for targeted erase/updates (series-level).
• Low Power & Reliability  Industrial temperature grade (−40 °C to 85 °C) and designed for minimum 100K program/erase cycles and 20 years data retention (series-level).
• Package & Mounting  Surface-mount SOP package (SOP 5 / 8-pin form factor per product specifications) for compact board-level integration.
• Supply  Rated supply voltage per product specification: 2.5 V.

Typical Applications

• Embedded firmware storage  Store boot code, firmware and configuration in a compact, non-volatile memory with sector-level erase and page programming.
• Industrial control  Reliable code and calibration data storage across −40 °C to 85 °C for PLCs, motor drives and factory automation modules.
• IoT and edge devices  Local non-volatile storage for firmware updates, parameter logging and small file storage in space-constrained designs.
• Consumer and appliance controllers  Code shadowing, configuration retention and field update capability in small-footprint SOP packages.

Unique Advantages

• Compact industrial package: SOP surface-mount form factor that simplifies board layout and reduces BOM footprint for space-constrained designs.
• Wide operating temperature: −40 °C to 85 °C rating makes the part suitable for industrial environments requiring temperature robustness.
• High-speed SPI support: 104 MHz clock capability and support for Standard/Dual/Quad SPI modes (series-level) enable faster code and data read operations.
• Fine-grained erase control: Uniform 4 Kbyte sectors and larger block erase options allow targeted updates and reduce erase/program cycles where only small regions change.
• Longevity and reliability: Specified endurance of a minimum 100K program/erase cycles and 20-year data retention (series-level) for long-term deployments.
• Low-power operation: Designed for low active and standby currents (series-level), helping reduce system-level power consumption.
