EN25S40A-104RBIP(2S)

The EN25S40A-104RBIP(2S) is a 4 Mbit serial NOR flash memory in the ESMT EN25S40A(2S) series, optimized for robust code and data storage in industrial embedded designs. Built on a Serial Peripheral Interface (SPI) architecture, it supports Standard, Dual and Quad SPI modes for flexible performance scaling.

With full support for high-speed SPI clocking and a uniform sector architecture, this device is designed for firmware storage, secure data segments and system-level non-volatile storage where performance, endurance and industrial temperature operation matter.

Key Features

• Memory Capacity & Organization — 4 M-bit total capacity (512 KByte) organized as 512K × 8 with 256-byte programmable pages and 2048 pages for granular programming.
• SPI Interface & Performance — Serial SPI compatible in Mode 0 and Mode 3 with Standard, Dual and Quad I/O; supports equivalent high-rate transfers up to 104 MHz per clock lane for single, dual and quad operation.
• Uniform Sector Architecture — 4-KByte uniform sectors (128 sectors), plus 32-KByte and 64-KByte block groupings for flexible erase granularity and memory management.
• Program / Erase Performance — Typical page program time 0.30 ms; sector erase ~40 ms typ.; 32 KB block erase ~100 ms typ.; 64 KB block erase ~150 ms typ.; chip erase ~2 s typ.
• Reliability & Retention — Minimum 100K program/erase cycles per sector or block and 20 years data retention.
• Protection & Security — Software and hardware write protection with WP# pin support; lockable 512-byte OTP security sector; supports Write Suspend/Resume for flexible erase/program workflows.
• Low Power — Typical active current ~6 mA and typical power-down current ~0.1 μA for power-conscious deployments.
• Package & Temperature — Available in an 8-pin VSOP 150 mil package; industrial operating temperature range −40°C to 85°C; RoHS compliant.
• Additional Features — Burst read modes (8/16/32/64 linear burst with wrap-around), SFDP support and Read Unique ID Number feature (per datasheet note).

Typical Applications

• Industrial Embedded Systems — Firmware and configuration storage for controllers, instrumentation and industrial automation operating across −40°C to 85°C.
• IoT & Edge Devices — Reliable non-volatile storage for boot code, firmware updates and parameter storage where low standby current and sector-level erasure are required.
• Consumer & Networked Electronics — Code shadowing, system firmware and lookup-table storage using high-speed SPI and Dual/Quad modes to accelerate read throughput.

Unique Advantages

• Flexible Performance Scaling: Standard, Dual and Quad SPI modes with 104 MHz clocking let designers trade off pin usage and throughput without changing the memory family.
• Granular Memory Management: 4-KB uniform sectors plus larger block erase options enable targeted updates and minimize erase/program overhead for in-field firmware patches.
• Industry-Ready Reliability: 100K minimum P/E cycles and 20-year data retention provide long-term stability for industrial deployments.
• Low Power Operation: Typical active and power-down currents support battery-assisted and always-on systems while maintaining fast program/read capability.
• Hardware & Software Protection: WP# pin and software protection mechanisms, plus a lockable 512-byte OTP sector, help safeguard critical code and data segments.
• Compact Packaging: 8-pin VSOP 150 mil packaging provides a small PCB footprint for space-constrained designs while maintaining industrial temperature range capability.
