EN25E40A-104XFIP(2A)

The EN25E40A-104XFIP(2A) is a 4 M-bit serial SPI NOR Flash memory device in the ESMT EN25E40A(2A) series. It provides a uniform-sector architecture and supports high-speed SPI and Dual SPI operation for code and data storage in embedded systems.

Designed for industrial environments, the device combines a 104 MHz clock capability, low-power modes, and an 8‑pin USON 2×3 mm surface‑mount package, making it suitable for compact, temperature‑sensitive designs requiring non‑volatile program and data storage.

Key Features

• Memory Capacity & Organization — 4 M‑bit total capacity (4.194 Mbit / 512 K‑byte) organized as 2,048 pages with 256 bytes per programmable page.
• High‑speed SPI Interface — Standard SPI compatible with Mode 0 and Mode 3 at up to 104 MHz; Dual SPI supports equivalent 208 MHz operation using two data lines.
• Uniform Sector Architecture — 128 sectors of 4 KB, 16 blocks of 32 KB and 8 blocks of 64 KB allow granular erase and program operations.
• Program & Erase Performance — Typical page program time 0.6 ms; typical sector erase time 50 ms; typical 32 KB block erase 150 ms and 64 KB block erase 300 ms; typical chip erase 2.5 s.
• Low Power — Typical active current 5 mA and typical power‑down current 1 µA for energy‑sensitive designs.
• Write Protection — Software and hardware write protection options including WP# pin and software‑protected regions.
• Endurance & Retention — Minimum 100 K program/erase cycles per sector and typical data retention of 20 years.
• Supply & Temperature — Nominal supply noted at 2.5 V; device datasheet lists full operating voltage range 2.3–3.6 V. Industrial operating temperature from −40 °C to 85 °C.
• Package & Mounting — 8‑contact USON 2×3×0.45 mm surface‑mount package (also available in SOP and WLCSP variants per series datasheet).

Typical Applications

• Embedded Code Storage — Store bootloaders, firmware images, and lookup tables in space‑constrained microcontroller designs.
• Industrial Control — Non‑volatile configuration and firmware storage across −40 °C to 85 °C operating range.
• Consumer & IoT Devices — Compact SPI NOR memory for firmware, calibration data, and local non‑volatile storage.

Unique Advantages

• High SPI Throughput: 104 MHz clock and Dual SPI support enable faster code fetch and data transfers without changing host architecture.
• Granular Erase Flexibility: Uniform 4 KB sectors plus 32 KB and 64 KB block options let you optimize erase size for wear leveling and update efficiency.
• Low Standby Power: Typical 1 µA power‑down current conserves energy in battery‑powered or always‑on systems.
• Robust Endurance and Retention: 100 K program/erase cycles and 20‑year data retention provide long service life for fielded products.
• Hardware & Software Protection: WP# pin and software protection modes simplify secure updates and write control across the memory map.
• Compact Industrial Package: 8‑pin USON 2×3 mm SMD package supports small PCBs while meeting industrial temperature requirements.
