EN25S64A-104WIP

The EN25S64A-104WIP from ESMT is a 64 Mbit serial NOR flash memory device optimized for SPI-based embedded storage. It implements a serial interface architecture with Standard, Dual and Quad SPI modes and a uniform 4-Kbyte sector architecture suited for code and data storage in industrial systems.

Designed for industrial operation, the device delivers high read throughput (up to 104 MHz in fast/dual/quad modes), flexible protection options and low standby current, making it appropriate for firmware storage, code shadowing and field-update applications where reliability and compact packaging matter.

Key Features

• Memory Capacity & Organization  64 Mbit (8,192 KByte) capacity with 32,768 pages and 256 bytes per programmable page; uniform sector architecture with 4-Kbyte sectors, 32-Kbyte and 64-Kbyte blocks.
• Interface  SPI-compatible serial interface supporting Standard, Dual and Quad SPI commands (CLK, CS#, DI, DO, WP#, HOLD#/RESET# and DQ₀–DQ₃ for multi-bit modes).
• High-Speed Read  Normal read at 83 MHz and fast read modes supporting up to 104 MHz (Standard and Dual SPI with 1 dummy byte; Quad SPI with 3 dummy bytes).
• Program & Erase Performance  Typical page program time 0.5 ms; sector erase ~40 ms typical; half-block and block erase times and a typical chip erase of 32 seconds.
• Power and Supply  Single power supply operation with full voltage range 1.65–1.95 V; low power consumption with typical active current ~3.5 mA and power-down current ~1 μA.
• Reliability & Endurance  Minimum 100K program/erase cycles per sector and data retention typically 20 years.
• Security & Protection  Software and hardware write protection, lockable 512‑byte OTP security sector, Read Unique ID and support for write suspend/resume operations.
• Package & Temperature  Industrial-grade device in an 8‑pin WSON (5×6 mm) surface-mount package with operating temperature range −40 °C to 85 °C.

Typical Applications

• Industrial Control  Non-volatile storage for firmware and configuration data in PLCs, sensors and controllers operating across industrial temperature ranges.
• Embedded Systems  Code shadowing and boot storage for microcontroller-based designs requiring reliable in-field updates and block-level protection.
• Networking & Communications  Storage of boot code, configuration and calibration data in routers, gateways and edge devices that leverage fast SPI reads.
• IoT Devices  Compact, low-power firmware and data storage for connected sensors and devices where small package size and low standby current are important.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support enables designers to trade off pin count and throughput to match system requirements.
• Uniform Sector Architecture: 4‑Kbyte sectors with individually erasable blocks simplify firmware update strategies and reduce erase scope during field patches.
• Fast Read Throughput: Up to 104 MHz fast read modes accelerate boot and execute-in-place workflows, improving system responsiveness.
• Robust Protection Features: Software and hardware write protection plus a lockable OTP sector protect critical code and sensitive data.
• Industrial Grade Packaging: Available in a compact 8‑lead WSON (5×6 mm) package and rated for −40 °C to 85 °C operation for space-constrained, rugged designs.
• Low Power Standby: Microamp-range power-down current helps minimize power consumption in battery-powered or always-on systems.
