EN25SX64A-133HIP(2U)

The EN25SX64A-133HIP(2U) is a 64 Megabit serial SPI NOR Flash memory device from ESMT designed for industrial-grade embedded storage. It implements a serial interface architecture (Single/Dual/Quad SPI) and a uniform-sector memory organization to support reliable code and data storage in constrained system designs.

This device targets applications that require fast Quad I/O reads at up to 133 MHz, advanced block-level protection, and long-term data retention while operating across an industrial temperature range.

Key Features

• Memory Capacity & Organization — 64 Mbit (8,192 K-byte) organized as 8M × 8 with 256-byte programmable pages and 2,048 uniform 4-Kbyte sectors for fine-grained erase and program control.
• Serial SPI Interface — Supports Standard, Dual and Quad SPI modes with CLK, CS#, DI/DO and DQ pins; compatible with SPI Mode 0 and Mode 3 for flexible system integration.
• High-Speed Read — Dedicated 133 MHz Quad I/O Fast Read capability (104 MHz for Single/Dual/Quad I/O Fast Read), enabling accelerated code fetch and data throughput.
• Program & Erase Performance — Typical page program time 0.5 ms; typical sector erase time 40 ms; half-block and block erase times and a chip erase option provide scalable maintenance operations.
• Write Protection & Security — Software and hardware write protection options, WP# pin control, and a lockable 3 × 512‑byte OTP security sector to protect critical regions.
• Reliability & Data Retention — Minimum 100k program/erase cycles per sector and 20 years data retention, suitable for long-life embedded deployments.
• Low Power — Typical active current 4.5 mA and typical power-down current 0.1 µA for energy-conscious systems.
• Operating Range & Package — Single-supply operation over 1.65–1.95 V (1.8 V device family) and industrial temperature range −40 °C to +85 °C; available in an 8-pin SOP 200 mil package (surface mount) for compact board-level integration.

Typical Applications

• Firmware and Boot Storage — Reliable non-volatile storage for boot code and firmware images where sector-level protection and fast read performance are required.
• Field Upgrade & Patchable Code — Supports in-field code patching and module-level updates by enabling protection/unprotection of individual blocks or sectors.
• Industrial Embedded Systems — Industrial temperature range and low-power standby make it suitable for embedded controllers, instrumentation, and industrial communications equipment.

Unique Advantages

• Dedicated 133 MHz Quad I/O Part — Optimized for high-speed Quad I/O Fast Read to improve system boot and code execution times.
• Uniform Sector Architecture — 4-Kbyte uniform sectors allow precise erase and update operations without affecting neighboring data.
• Flexible Protection Mechanisms — Combined software and hardware write protection plus a lockable OTP sector reduce risk of accidental or malicious modification.
• Proven Endurance and Retention — 100k program/erase cycles and 20-year data retention support long-term product lifecycles.
• Compact Industrial Packaging — 8-pin SOP 200 mil surface-mount package offers a small footprint for space-constrained industrial PCBs.
• Low-Power Operation — Low active and standby currents help minimize system power budgets in always-on or battery-assisted devices.
