EN25QX64A-104GIP(2C)

The EN25QX64A-104GIP(2C) is a 67.11 Mbit non-volatile SPI NOR Flash memory device in an 8‑pin SOP 150mil surface-mount package. It implements a serial SPI architecture with Single/Dual/Quad I/O options and is targeted at industrial-class embedded applications that require reliable code and data storage across a wide operating temperature range.

Designed for high-performance read access and secure firmware storage, the device combines fast 104 MHz read capability with software and hardware protection mechanisms, making it suitable for systems that need robust non-volatile memory with low standby power and industrial-grade environmental tolerance.

Key Features

• Memory Capacity & Organization 67.11 Mbit density organized as 8M × 8, supporting 32,768 programmable pages and 256 bytes per page for flexible code and data storage.
• Serial SPI Architecture SPI NOR Flash technology with support for Standard, Dual and Quad SPI modes; compatible with SPI Mode 0 and Mode 3 for broad host controller interoperability.
• High-Speed Read Performance 104 MHz clock rate for fast read operations, enabling quicker boot and code fetch compared with lower-speed serial memories.
• Program / Erase Performance Page and block program/erase operations with practical timing characteristics (write cycle time — word/page listed at 3 ms in specifications); supports page programming up to 256 bytes.
• Sectored Erase Architecture Uniform sector architecture with 2,048 sectors of 4 KB, 256 blocks of 32 KB and 128 blocks of 64 KB, allowing targeted erase operations without affecting the entire array.
• Data Protection & Security Software and hardware write protection, dedicated WP# control, software-enabled protection modes and lockable 3 × 512‑byte One-Time-Programmable (OTP) security sectors.
• Low Power & Reliability Low standby current and modest active current levels (series datasheet notes low-power operation); device endurance and retention characteristics support robust long-term data storage for embedded systems.
• Industrial Temperature Range Qualified for operation from −40 °C to 85 °C, suitable for industrial environments.
• Package & Mounting Surface-mount 8‑pin SOP 150mil package for compact board-level integration and standard assembly flows. RoHS compliant.

Typical Applications

• Industrial Embedded Controllers Stores firmware and configuration data in industrial controllers where wide temperature range and hardware write protection are required.
• Boot and Code Storage Fast 104 MHz read performance accelerates boot times and code fetch for systems that load firmware from external flash.
• Field Upgrades and Patching Uniform sector architecture and software/hardware protection enable safe in-field firmware updates with selective sector erase and program.
• Data Logging and Non-Volatile Storage Provides reliable non-volatile storage for event logs and calibration data with long data retention and endurance characteristics.

Unique Advantages

• Fast Serial Read Access: 104 MHz SPI operation supports higher throughput for code and data reads, improving system responsiveness during boot and runtime fetches.
• Flexible I/O Modes: Standard/Dual/Quad SPI support gives designers options to trade pin usage for throughput without changing the memory family.
• Granular Erase Control: Uniform 4 KB sectors and multiple block sizes let you erase only what’s necessary, reducing wear and simplifying firmware update strategies.
• Hardware and Software Protection: WP# pin and software protection bits plus lockable OTP sectors help safeguard critical code and secure data areas.
• Industrial-Grade Robustness: Rated for −40 °C to 85 °C operation and supplied in an industry-standard surface-mount package for reliable deployment in harsh environments.
• Low Power Standby: Designed for low standby current to minimize energy drain in battery-assisted or always-on systems.
