EN25E40A-104GIP(2A)

The EN25E40A-104GIP(2A) is a 4 Mbit (512 K-byte) SPI NOR serial flash memory designed for embedded and industrial applications. It implements a serial SPI architecture with Standard and Dual SPI modes to deliver high-throughput non-volatile storage for code, configuration and data logging.

Key use cases include firmware storage, system boot, configuration memory and field-upgradable devices where compact, low-power, and sector-erasable flash is required. The device combines a high 104 MHz SPI clock rate with a uniform sector architecture and industrial temperature range (−40°C to 85°C).

Key Features

• Core / Memory Capacity — 4 M-bit (512 K-byte) density organized as 512K × 8 with 256-byte programmable pages, suitable for firmware and configuration storage.
• High-Speed Serial Interface — SPI-compatible Standard and Dual SPI support with up to 104 MHz clock for Standard SPI and equivalent up to 208 MHz for Dual Output (104 MHz × 2).
• Uniform Sector Architecture — 128 sectors of 4 Kbyte each, with larger erase granularities available (16 × 32 Kbyte blocks and 8 × 64 Kbyte blocks) enabling flexible erase/program strategies.
• Program / Erase Performance — Typical Page Program time 0.6 ms; sector, block and chip erase options provide a range of erase times for targeted updates or full-chip operations.
• Low Power — Typical active current around 5 mA and typical power-down current approximately 1 µA, supporting low-power system designs.
• Reliability — Minimum 100k program/erase cycles per sector and 20-year typical data retention for long-term field deployments.
• Voltage and Packaging — Single-supply operation across a full range (2.3–3.6 V) and available in 8-pin SOP (150 mil) and other compact package options; surface-mount suitable for dense PCB layouts.
• Industrial Temperature Range — Specified for −40°C to 85°C operation to meet industrial environmental requirements.
• Write Protection — Software and hardware write-protect features including WP# pin and software-enabled protection for full or partial memory regions.

Typical Applications

• Industrial Control — Firmware storage and field updates for PLCs, motor controllers and automation modules operating across a wide temperature range.
• Embedded and IoT Devices — Non-volatile program and configuration storage for sensors, gateways and edge devices that require low power and compact packaging.
• Consumer and Appliance Electronics — Boot code, configuration parameters and UI assets where reliable, sector-erasable flash is required.
• Data Logging and Telemetry — Local storage for periodic logs and telemetry buffers with long data retention and robust program/erase endurance.

Unique Advantages

• Balanced Performance and Power: 104 MHz SPI clock with low active and deep-power-down currents provides fast access while minimizing energy consumption.
• Flexible Erase Granularity: 4 Kbyte uniform sectors plus larger 32 Kbyte and 64 Kbyte block options let designers optimize update sizes and erase time.
• Robust Endurance and Retention: Minimum 100k P/E cycles and 20-year data retention support long-life industrial deployments and field upgrades.
• Dual SPI Throughput: Dual output mode doubles effective data rate (104 MHz × 2) for faster read performance where needed.
• Hardware and Software Protection: WP# pin and software write-protect modes enable secure control over protected memory regions to prevent accidental overwrites.
• Compact, Surface-Mount Packages: 8-pin SOP (150 mil) and other package choices simplify board-level integration in space-constrained designs.
