• Interface SPI-compatible serial interface with Standard, Dual and Quad SPI support (CLK, CS#, DI/DO, DQ0–DQ3 as applicable).
• Performance High read clock rate up to 104 MHz for Standard SPI and equivalent higher throughput for Dual/Quad modes (up to 2× and 4× data rates using Dual/Quad I/O Fast Read).
• Program & Erase Page program typical time 0.6 ms; sector erase (4 KB) typical 50 ms; 32 KB block erase 120 ms typical; 64 KB block erase 150 ms typical; chip erase typical 15 seconds.
• Power Low active and standby currents with typical active current ~5 mA and typical power-down current ~1 µA.
• Reliability Minimum 100K program/erase cycles per sector and typical data retention of 20 years.
• Sector Architecture & Protection Uniform sector architecture with 1,024 × 4 KB sectors, 128 × 32 KB blocks and 64 × 64 KB blocks. Software and permanent protection options including programmable protection bits and lockable OTP sectors (three 512‑byte lockable security sectors).
• Voltage & Temperature Single power-supply operation with full voltage range documented in the product literature and industrial temperature range operation (–40 °C to 85 °C).
• Packages & Mounting Available in industry-standard packages including 8‑lead SOP (200 mil) and 24‑ball TFBGA; surface-mount mounting type.
• Standards & Identification Supports Serial Flash Discoverable Parameters (SFDP) signature and includes a Read Unique ID Number command.

Typical Applications

• Industrial and control systems — Industrial-grade temperature range and sector-level erase make the device suitable for embedded storage in industrial controllers and instrumentation.
• Embedded products requiring serial flash — SPI Standard/Dual/Quad support and high clock-rate operation provide flexible read performance for embedded code and data storage.
• Space-constrained PCB designs — Surface-mount packages such as 8‑lead SOP (200 mil) and 24‑ball TFBGA enable compact board layouts.

Unique Advantages

• High read throughput — 104 MHz clock rate for Standard SPI and support for Dual/Quad I/O enables higher effective data rates for fast code and data retrieval.
• Flexible erase granularity — Uniform sector architecture with 4 KB sectors and larger block sizes lets designers erase precisely where needed to minimize wear and speed maintenance operations.
• Low-power standby — Typical power-down current of ~1 µA helps reduce system power in idle states.
• Robust endurance and retention — Minimum 100K program/erase cycles and 20-year data retention provide long operational life for firmware and configuration storage.
• On-die protection features — Software and permanent protection mechanisms plus lockable OTP sectors enable controlled, secure memory regions for critical code and data.
• Industrial temperature support — Operation from –40 °C to 85 °C supports deployment in harsh or temperature-variable environments.
