EN25S16B-104HIP(2S)

The EN25S16B-104HIP(2S) is a 16.78 Mbit (2,048 KByte) SPI NOR serial flash memory designed for industrial embedded applications that require reliable non-volatile code and data storage. It implements a serial SPI architecture with Standard, Dual and Quad SPI modes to deliver high-speed read performance and flexible I/O options.

With uniform 4 Kbyte sector architecture, hardware and software write protection, and industrial temperature rating, this device targets firmware storage, field-updatable code, and data-logging use cases where endurance, low power and robust protection are important.

Key Features

• Memory & Organization — 16.78 Mbit capacity organized as 2,048 KBytes (2M × 8) with 8,192 pages and 256 bytes per programmable page.
• High-speed Read — Fast read capability up to 104 MHz (Standard/Dual SPI with 1 dummy byte; Quad SPI up to 104 MHz with 3 dummy bytes) for accelerated code fetch and data access.
• SPI Interface Modes — Supports Standard, Dual and Quad SPI (CLK, CS#, DI/DO, DQ₀–DQ₃) for flexible throughput and pin usage.
• Program & Erase Performance — Page program time reported in the series datasheet as 0.5 ms typical; device-level write cycle time is specified as 3 ms. Multiple erase granularities: 4 Kbyte sectors, 32 Kbyte and 64 Kbyte blocks, plus full chip erase.
• Protection & Security — Software and hardware write protection including configurable block protect, WP# pin, and a lockable 3×512 byte OTP security sector.
• Reliability & Endurance — Minimum 100K program/erase cycles per sector and 20 years data retention (series datasheet values).
• Low Power — Typical active current around 4.5 mA and typical power-down current of 0.1 µA (series datasheet figures).
• Voltage & Supply — Single power-supply operation with series datasheet full voltage range of 1.65–1.95 V.
• Package & Temperature — Surface-mount 8-pin SOP 200 mil package; industrial temperature range −40 °C to 85 °C.
• Standards & Discoverability — Supports Serial Flash Discoverable Parameters (SFDP) and Read Unique ID Number (as documented in the series datasheet).
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Firmware storage and field updates in PLCs, motor controllers and industrial gateways operating across −40 °C to 85 °C.
• Embedded Systems — Code and data storage for microcontroller-based devices where multi-mode SPI and high read throughput accelerate boot and runtime performance.
• Networking & Communications — Non-volatile storage of configuration, boot code and firmware images in routers, switches and edge devices.
• Instrumentation & Data Logging — Reliable storage for logged data and calibration parameters with long data-retention and sector-level erase flexibility.

Unique Advantages

• Flexible SPI Throughput: Standard, Dual and Quad SPI support allows designers to scale interface bandwidth without changing memory architecture.
• Uniform Sector Architecture: 4 Kbyte sectors and multiple block sizes enable precise erase/program operations to minimize flash wear and simplify partitioning.
• Robust Protection Options: Combined software and hardware write-protect features plus an OTP security sector provide layered protection for critical code and data.
• Industrial-grade Reliability: 100K minimum P/E cycles and 20-year retention (series datasheet) provide long-term stability for deployed systems.
• Low-power standby: Very low power-down current supports battery-backed or low-energy applications while preserving stored data.
• Compact Surface-mount Package: 8-pin SOP 200 mil package offers a small footprint for space-constrained board designs.
