EN25QW80A-104IP(2P)

The EN25QW80A-104IP(2P) is an 8 Mbit (1M × 8) serial NOR Flash memory device offering a high-performance SPI serial interface. Designed with uniform 4-Kbyte sectors and support for Standard, Dual and Quad SPI modes, it targets embedded code and data storage in industrial applications that require reliable non-volatile memory with in-field update capability.

Key value propositions include a 104 MHz clock rate across Standard/Dual/Quad SPI, low active and standby currents, and a broad operating temperature range of −40 °C to 85 °C, making it suitable for rugged designs that need fast read/write access and flexible protection features.

Key Features

• Memory Capacity and Organization 8.389 Mbit capacity (1M × 8 organization) with 4096 pages and 256 bytes per programmable page for byte-range programming.
• SPI Serial Interface Serial SPI architecture supporting Standard, Dual and Quad SPI modes; compatible with SPI Mode 0 and Mode 3 for flexible host integration.
• High-Speed Operation 104 MHz clock rate supported for Standard, two-bit and four-bit data transfers to accelerate read throughput.
• Uniform Sector Architecture 256 × 4-Kbyte sectors, 32 × 32-Kbyte blocks and 16 × 64-Kbyte blocks; any sector or block can be erased individually for efficient memory management.
• Program and Erase Performance Page program time typically 1 ms; typical sector, half-block and block erase times are 100 ms, 300 ms and 500 ms respectively (datasheet typical values); chip erase typical 8 seconds.
• Protection and Security Software and hardware write protection with WP# pin control, volatile status register bits, and a lockable 3 × 1024-byte OTP security sector for small secure storage.
• Endurance and Retention Minimum 100K program/erase cycles per sector or block and data retention typically 20 years.
• Power and Low-Power Modes Typical active current around 10 mA and typical power-down current around 1 μA to minimize system power when idle.
• Supply Voltage and Temperature Full device voltage range 1.65–3.6 V (datasheet) with a listed supply value of 2.5 V; industrial operating temperature −40 °C to 85 °C.
• Package Options and Mounting Surface-mount packages including 8-pin SOP (150 mil/200 mil) and 8-contact USON (3 × 2 × 0.45 mm); Pb-free, RoHS-compliant variants available.

Typical Applications

• Embedded code and firmware storage — Stores boot code and application firmware with sector-level erase and program flexibility for field updates and patches.
• Field-upgradeable systems — Supports in-place code/module patching and write-suspend/resume for reliable firmware updates in deployed devices.
• Configuration and parameter storage — Non-volatile storage for calibration data, device configuration and small secure data areas using the lockable OTP sector.
• Industrial controllers and equipment — Industrial-grade temperature range and low-power standby behavior suited to control modules, instrumentation and embedded industrial designs.

Unique Advantages

• Broad SPI mode support: Standard, Dual and Quad SPI modes plus configurable dummy cycles enable designers to balance throughput and pin usage for system requirements.
• Fast read performance: 104 MHz clock rate for single, dual and quad transfers reduces read latency for code and data fetches.
• Granular erase architecture: 4-Kbyte uniform sectors and multiple block sizes let designers optimize erase operations and minimize wear on critical regions.
• Robust protection options: Software and hardware write protection plus a lockable OTP sector provide layered safeguards for firmware and secure data.
• Low-power standby: Typical 1 μA power-down current supports energy-conscious designs while retaining non-volatile data.
• Industrial readiness: −40 °C to 85 °C operating range and Pb-free RoHS-compliant packages align with industrial deployment requirements.
