Key Features

• Density & Organization — 128 Mbit capacity (16,384 KByte) organized as 16M × 8 with 65,536 pages and 256 bytes per programmable page for fine-grained updates.
• Serial SPI Interface — SPI-compatible operation supporting Mode 0 and Mode 3, with Standard, Dual and Quad I/O for flexible performance scaling.
• High-Speed Read — 104 MHz clock rate for Single/Dual/Quad I/O Fast Read provides fast code/data fetch in embedded systems.
• Power Supply — Single power-supply operation with a full supply voltage range of 1.65–1.95 V (1.8 V class) for low-voltage system integration.
• Program & Erase Performance — Typical page program time 0.6 ms; sector erase ~50 ms; half-block and block erase times and a typical chip erase time of ~80 s for system-level maintenance.
• Low Power — Typical active current ~5 mA and typical power-down current ~3 µA to minimize system power draw.
• Sector Architecture & Protection — Uniform 4 KB sectors (4,096 sectors) with software and hardware write-protection mechanisms plus a lockable OTP region for security.
• Endurance & Retention — Minimum 100k program/erase cycles per sector and 20 years data retention, suitable for long-lived industrial deployments.
• Package & Mounting — 8-pin USON (4 × 4 mm) surface-mount package to support compact board designs.
• Temperature & Compliance — Industrial temperature operation (series-level support to -40 °C to 105 °C) and RoHS-compliant construction.

Typical Applications

• Industrial Control — Firmware and configuration storage for PLCs, motor drives and controllers where reliable non-volatile code storage is required.
• Embedded Communications — Boot and parameter storage in routers, gateways and industrial edge devices using SPI-based host controllers.
• Firmware Update Systems — Partitioned flash with uniform 4 KB sectors and write-protect features enables field firmware updates and secure rollback strategies.
• IoT & Edge Devices — Compact 8-pin package and low-power standby make it suitable for space-constrained, battery-aware edge modules.

Unique Advantages

• Flexible I/O Performance: Standard, Dual and Quad SPI support with a 104 MHz fast-read clock lets designers trade off pin count and throughput to match system needs.
• Fine-Grained Memory Control: 256-byte page programming and 4 KB uniform sectors enable efficient updates and minimize erase overhead for partial updates.
• Robust Data Longevity: 100k P/E cycles and 20-year data retention provide durability and predictable lifecycle behavior for industrial systems.
• Low-Voltage Operation: 1.65–1.95 V single-supply operation supports modern low-voltage SoCs and reduces system power complexity.
• Compact, Surface-Mount Package: 8-pin USON (4 × 4 mm) packaging supports high-density PCB layouts without sacrificing accessibility for SPI signals and protection pins.
• Hardware & Software Protection: Integrated write-protect pin and software protection options simplify safeguarding critical code and data regions.
