EN25S40A-104GIP(2S)

The EN25S40A-104GIP(2S) is a 4 Mbit serial NOR Flash memory device in an industrial-grade 8‑pin SOP (150 mil) package. Built on an SPI NOR architecture, it provides high-performance read modes with Standard, Dual and Quad SPI support and flexible erase/program operations for firmware and non-volatile data storage.

Designed for embedded and industrial applications, the device combines high clock-rate access, uniform sector architecture and multiple protection mechanisms to support reliable code storage, field updates and secure data retention across a wide operating temperature range.

Key Features

• Memory Capacity & Organization  4,194,304‑bit (4 Mbit) capacity organized as 512K × 8 with 256‑byte programmable pages and 2,048 pages per device.
• SPI Interface & Modes  Serial SPI architecture compatible with Standard, Dual and Quad SPI using CLK, CS# and DQ pins for high‑speed read and I/O.
• High Performance  Supports up to 104 MHz clock rate for single, dual and quad data transfers to enable fast code and data reads.
• Uniform Sector Architecture  128 uniform 4‑KB sectors, 16 blocks of 32‑KB and 8 blocks of 64‑KB, allowing individual sector or block erase operations.
• Program and Erase Speed  Typical page program time 0.30 ms; typical sector erase 40 ms; 32 KB block erase 100 ms; 64 KB block erase 150 ms; chip erase 2 seconds typical.
• Low Power  Low active current (typical 6 mA) and ultra-low power down current (typical 0.1 μA) for power‑sensitive designs.
• Write Protection & Security  Software and hardware write protection with WP# pin, lockable 512‑byte OTP security sector, and support for selective block protection.
• Reliability  Minimum 100K program/erase cycles per sector and 20 years data retention for long‑term non‑volatile storage.
• Industrial Temperature & Packaging  Rated for –40 °C to 85 °C operation and supplied in an 8‑pin SOP 150 mil package (surface mount).

Typical Applications

• Industrial Control  Stores firmware and configuration data reliably across –40 °C to 85 °C for PLCs, motor drives and factory automation.
• IoT and Edge Devices  Compact 8‑pin package and low power standby make it suitable for resource‑constrained IoT modules and sensor gateways.
• Embedded Firmware Storage  Fast read modes and uniform sector erase support firmware execution, boot code storage and field firmware updates.
• Secure Data Logging  Lockable OTP sector and selective block protection enable protected storage of calibration, ID or security data.

Unique Advantages

• High-throughput SPI operations: Delivers up to 104 MHz clock-rate transfers with Standard, Dual and Quad modes to accelerate code fetch and data reads.
• Flexible erase granularity: 4‑KB uniform sectors plus 32 KB and 64 KB block options let you minimize erase overhead and reduce wear for frequently updated regions.
• Robust program/erase endurance: Rated for at least 100K cycles per sector, supporting frequent updates and long operational life.
• Low-power standby: Typical power down current of 0.1 μA helps extend battery life in portable and remote systems.
• Hardware and software protection: Combined WP# pin and software protection allow selective locking of critical code and data regions to prevent accidental or malicious modification.
• Industrial-ready packaging: 8‑pin SOP (150 mil) surface mount package and wide operating temperature range support compact board designs in harsh environments.
