EN25QY256A-133IP(2S)

The EN25QY256A-133IP(2S) is a 256 Mbit serial SPI NOR flash memory in a compact SOP8 package, designed for industrial temperature operation. It implements a flexible SPI serial architecture (Standard, Dual and Quad I/O) with a 133 MHz Quad I/O Fast Read clock to deliver high‑performance code and data storage for embedded systems.

With uniform 4-Kbyte sectors, 256‑byte programmable pages and hardware/software write protection options, this device is targeted at industrial and embedded applications that require reliable non‑volatile storage, high read throughput and robust program/erase capability.

Key Features

• Serial SPI Architecture Standard, Dual and Quad SPI support with Standard SPI pins and Quad I/O Fast Read at up to 133 MHz.
• Memory Organization 256 Mbit capacity presented as 32M × 8 with 131,072 pages and 256 bytes per programmable page.
• Uniform Sector Architecture 8,192 uniform 4-Kbyte sectors (also supports 32-Kbyte and 64-Kbyte blocks) allowing individual sector or block erase operations.
• Fast Program/Erase Typical page program time 0.5 ms and typical sector erase time 40 ms; chip erase and block/half‑block erase times also provided.
• Power and Voltage Single supply operation across the specified voltage range with low active current (typical 7 mA) and low power‑down current (typical 1 µA).
• Reliability Minimum 100K program/erase cycles per sector and greater than 20‑year data retention.
• Security and Protection Lockable 3×512‑byte OTP sector, software and hardware write protection with WP# control and configurable protection bits.
• Package and Temperature Available in SOP8 (200 mil) surface‑mount package and specified for industrial temperature range (−40 °C to 85 °C).
• Advanced Features Configurable dummy cycles, 3‑byte/4‑byte address mode switch, SFDP support and a Read Unique ID command for system-level identification.

Typical Applications

• Industrial Equipment Reliable firmware and data storage for controllers and instrumentation operating across the industrial temperature range.
• Embedded Systems Code shadowing and non‑volatile program storage where fast Quad I/O reads and page programming improve boot and update times.
• Networking & Telecom Modules Storage of configuration, firmware and boot code that benefits from fast read throughput and uniform sector erase.
• IoT and Edge Devices Persistent storage for firmware, secure IDs and small data logs with low power standby behavior for energy‑sensitive deployments.

Unique Advantages

• Quad I/O at 133 MHz: Higher read bandwidth for faster system boot and code execute‑in‑place (XIP) scenarios.
• Uniform 4 KB Sectors: Fine‑grained erase control simplifies firmware updates and reduces unnecessary erase cycles.
• Robust Endurance and Retention: Specified for a minimum of 100K program/erase cycles and over 20 years of data retention to support long‑lived deployments.
• Flexible Protection Options: Combination of hardware WP#, software protect, and a lockable OTP sector to manage secure and controlled updates.
• Industrial Temperature Range: Qualified for −40 °C to 85 °C operation to meet demanding environmental requirements.
