EN25QX256A-104HIP(2S)

The EN25QX256A-104HIP(2S) is a 256 Mbit serial NOR flash memory in a compact 8-pin SOP 200mil package, designed for industrial-temperature use. Based on a serial SPI architecture, it delivers high-speed read performance and flexible I/O modes suitable for code storage, firmware update storage, and general non-volatile data logging in embedded systems.

With a 104 MHz maximum clock rate for Fast Read operations, uniform 4 KB sectors, and hardware/software write protection features, this device targets industrial applications that require reliable non-volatile storage with long data retention and robust program/erase endurance.

Key Features

• Memory Capacity & Organization — 256 Mbit (32M × 8) organization with 131,072 programmable pages and 256 bytes per page, providing large, addressable non-volatile storage.
• Serial SPI Architecture — SPI-compatible serial interface supporting Standard, Dual and Quad I/O modes with SPI Mode 0 and Mode 3 compatibility for flexible system integration.
• High-Speed Read — 104 MHz clock rate for Single/Dual/Quad I/O Fast Read; the series also documents support for up to 133 MHz Quad I/O Fast Read under 3.0–3.6 V operation.
• Uniform Sector Architecture — 8,192 sectors of 4 KB, plus 1,024 blocks of 32 KB and 512 blocks of 64 KB, allowing fine-grained erase and update operations.
• Program & Erase Performance — Typical page program time 0.5 ms and sector erase time 40 ms, with larger block and chip erase timings defined for batch operations.
• Endurance & Retention — Minimum 100K program/erase cycles per sector or block and 20 years data retention, supporting long-lived deployments.
• Power & Low-Power Modes — Typical active current around 7 mA and typical power-down current around 1 μA for energy-conscious designs.
• Hardware & Software Protection — WP# pin plus software protection mechanisms enable selective write protection and the ability to lock/unlock sectors as needed.
• Package & Temperature — Available in an 8-pin SOP 200mil surface-mount package and rated for industrial operating range of −40 °C to 85 °C.
• Standards & Discoverability — Supports Serial Flash Discoverable Parameters (SFDP) signature and Read Unique ID Number for device identification and system verification.
• Compliance — RoHS-compliant, lead-free package options.

Typical Applications

• Embedded Firmware Storage — Store boot code and firmware images with uniform 4 KB sectors to support in-field updates and secure region protection.
• Industrial Control — Non-volatile configuration and logging memory for industrial controllers and instrumentation operating across −40 °C to 85 °C.
• Consumer & IoT Devices — Code and data storage for connected devices that benefit from SPI interface flexibility and low-power standby modes.
• Secure Identification — Use Read Unique ID and lockable OTP sectors to implement device identity and small secure storage regions.

Unique Advantages

• Flexible I/O Modes: Support for Standard, Dual and Quad SPI I/O enables designers to trade off pin count versus throughput without changing memory architecture.
• Granular Erase Control: Uniform 4 KB sectors plus larger block sizes let systems erase only what they need, reducing wear and accelerating updates.
• Industrial Reliability: Industrial temperature rating and 100K program/erase cycle minimum provide predictable lifetime characteristics for long-term deployments.
• Low Power Standby: Typical 1 μA power-down current helps minimize energy use in battery-powered or always-on systems.
• Identifiable & Lockable Regions: SFDP support, unique ID, and lockable OTP sectors assist in secure provisioning and device management.
• Compact Surface-Mount Package: 8-pin SOP 200mil body supports small PCB footprints while retaining robust pinout options for HOLD# and WP# signals.
