EN25S40A-104WIP(2SC)

The EN25S40A-104WIP(2SC) is a 4.194 Mbit serial NOR Flash memory in a compact 8‑pin WSON (5×6 mm) surface-mount package, designed for industrial-temperature applications. It uses a serial SPI architecture with support for Standard, Dual and Quad SPI modes to deliver flexible, high-speed read performance up to a 104 MHz clock rate.

Built for embedded storage, code shadowing and field-update scenarios, this device provides uniform 4 KB sectors, fast program/erase operations, hardware and software write protection features, and low-power modes to suit battery‑aware and always‑on systems across an operating range of −40 °C to 85 °C.

Key Features

• Memory Architecture 4.194 Mbit organized as 512K × 8 with 2048 pages (256 bytes per programmable page) and a uniform sector architecture of 128 × 4 KB sectors, plus 16 × 32 KB and 8 × 64 KB blocks for flexible erase granularity.
• Serial SPI Interface & Modes SPI‑compatible serial interface supporting Mode 0 and Mode 3, with Standard, Dual and Quad I/O options to accelerate read throughput.
• High-Speed Read Performance Supports a 104 MHz clock rate for single-bit, dual-bit and quad-bit read operations, and supports linear burst modes (8/16/32/64 with wrap-around) for efficient sequential reads.
• Program / Erase Performance Typical page program time approximately 0.30 ms, sector erase typically 40 ms, 32 KB block erase typically 100 ms, 64 KB block erase typically 150 ms, and full chip erase typically 2 seconds.
• Write Protection & Security Software and hardware write protection (WP#), write-protectable regions, write suspend/resume, and a lockable 512‑byte OTP security sector. Supports Serial Flash Discoverable Parameters (SFDP) and a Read Unique ID feature.
• Power & Reliability Low active current (typical 6 mA), ultra-low power-down current (typical 0.1 μA), guaranteed minimum 100K program/erase cycles per sector, and 20-year data retention.
• Industrial Grade & Package Industrial temperature range −40 °C to 85 °C, RoHS‑compliant, surface-mount 8‑pin WSON (5×6 mm) package suitable for compact board designs.

Typical Applications

• Embedded firmware storage — Non-volatile code storage and boot code shadowing for microcontroller-based systems requiring fast read access and reliable program/erase cycles.
• Industrial control — Parameter and configuration storage in industrial controllers and instrumentation where wide temperature range and robust endurance are required.
• Field firmware updates — In-place updates and code patching using sector/block erase and program capabilities with hardware/software protection to limit accidental modification.
• IoT and edge devices — Compact, low-power non-volatile storage for configuration, logs or code in space-constrained, battery-conscious designs.

Unique Advantages

• Compact industrial package: The 8‑pin WSON (5×6 mm) surface-mount package minimizes PCB footprint while maintaining industrial temperature rating for robust deployments.
• Flexible SPI modes: Standard, Dual and Quad SPI support lets designers trade off pin usage and throughput for application needs, while maintaining a single serial interface architecture.
• Fine-grained erase control: Uniform 4 KB sectors together with larger block options allow precise updates with minimal erase overhead, reducing wear on targeted regions.
• Fast program/erase cycles: Sub-millisecond page program times and optimized erase times accelerate firmware updates and reduce downtime during in-field maintenance.
• Low-power operation: Typical active and power-down currents support energy-conscious systems and extend operational life in battery‑powered applications.
• Data integrity and lifecycle: High endurance (≥100K cycles) and 20‑year retention provide a predictable lifecycle for long-lived products.
