EN25Q40B-104HIP(2X)

The EN25Q40B-104HIP(2X) is a 4 Mbit (512 K-byte) serial NOR Flash memory device with a high-performance SPI architecture. It supports Standard, Dual and Quad SPI I/O and delivers up to 104 MHz clock operation for high-speed read access.

Designed for industrial temperature operation (−40 °C to 85 °C), the device combines uniform 4 Kbyte sectors, flexible erase/program options and low-power operation to serve embedded storage needs such as code storage, firmware updates and configuration data in space-constrained, surface-mount applications.

Key Features

• Memory Capacity & Organization — 4 Mbit (512 K-byte) memory organized as 512K × 8 with 256-byte programmable pages and 128 uniform 4-Kbyte sectors.
• SPI Serial Interface — Supports Standard, Dual and Quad SPI modes with Standard SPI signals and Dual/Quad I/O options for higher throughput.
• High-Speed Read — Up to 104 MHz clock rate for Standard, Dual and Quad SPI, enabling faster code and data reads in read-dominant systems.
• Program & Erase Performance — Page program operation (up to 256 bytes) and typical page program time of 0.5 ms; typical sector erase 40 ms, 32 KB block erase 0.12 s, 64 KB block erase 0.15 s and chip erase 2 s.
• Power — Low-power operation with typical active current around 5 mA and power-down current around 1 μA for energy-sensitive designs.
• Reliability & Retention — Minimum 100K program/erase cycles per sector and 20 years data retention for long-term firmware and code storage.
• Security & Protection — Hardware WP# pin plus software write protection options and lockable OTP (three 512-byte security sectors) for protected data regions.
• Industry-Grade Operating Range — Specified for industrial temperature operation from −40 °C to 85 °C and available in RoHS-compliant Pb-free packages.
• Package & Mounting — Surface-mount 8‑lead SOP (200 mil) option among multiple package choices suitable for compact PCB layouts.

Typical Applications

• Embedded Firmware Storage — Stores boot code and firmware images where fast read performance and reliable long-term retention are required.
• Configuration & Calibration Data — Maintains device configuration, calibration tables and small non-volatile datasets with sector-level erase and protection.
• Consumer & Industrial Controllers — Provides code and parameter storage for microcontroller-based systems operating across industrial temperature ranges.
• Boot & Fail-Safe Code — Holds critical bootloaders and recovery routines with write-protect and OTP options to secure essential code.

Unique Advantages

• Flexible SPI I/O Modes — Standard, Dual and Quad SPI support lets designers scale read throughput without changing core memory architecture.
• Uniform Sector Architecture — 4 Kbyte sectors with individually erasable sectors simplify update strategies and reduce unnecessary erase cycles.
• Low Power Footprint — Typical 5 mA active and 1 μA power-down currents reduce system power during active use and deep-sleep states.
• Industrial Temperature Range — Specified −40 °C to 85 °C operation for reliable use in temperature-challenging environments.
• Proven Endurance & Retention — Minimum 100K program/erase cycles and 20 years data retention support long product lifecycles and field updates.
