EN25QE16A-104GIP(2P)

The EN25QE16A-104GIP(2P) is a 16 Mbit serial NOR Flash memory from ESMT designed for high-performance, non-volatile code and data storage. It implements a Serial Peripheral Interface (SPI) architecture with support for Standard, Dual and Quad SPI modes to accelerate read and program throughput.

With a full supply voltage range of 2.3–3.6 V, a 104 MHz clock rate for 1/2/4-bit SPI operation, and an industrial operating temperature range of −40 °C to 85 °C, this device targets embedded and industrial applications that require fast reads, flexible I/O and robust data retention.

Key Features

• Memory & Organization — 16.78 Mbit capacity organized as 2M × 8 (2048 KByte) with 8192 programmable pages and 256 bytes per page.
• Interface & Performance — SPI compatible serial interface supporting Standard, Dual and Quad SPI; 104 MHz clock rate for single, dual and quad data modes for high-speed reads.
• Uniform Sector Architecture — 512 × 4-Kbyte sectors, 64 × 32-Kbyte blocks and 32 × 64-Kbyte blocks; any sector or block can be erased individually for efficient update and storage management.
• Program and Erase Speed — Typical page program time 1 ms; sector erase time typically 100 ms; half-block and block erase times and chip erase (typ. 15 seconds) support rapid field updates.
• Low Power — Low active current (typical 10 mA) and low power-down current (typical 1 μA) to minimize system power during idle periods.
• Data Protection & Security — Software and hardware write protection, WP# pin support, write suspend/resume and a lockable 3 × 1024-byte OTP security sector to protect critical code and data.
• Reliability — Minimum 100K program/erase cycles per sector and data retention typically 20 years for long-term field reliability.
• Package & Temperature — Available in 8-pin SOP 150 mil package (surface mount) and specified for industrial temperature operation from −40 °C to 85 °C. RoHS compliant.

Typical Applications

• Embedded Systems — Store boot code, firmware and on-device applications with sector-level erase and page program flexibility for patching and updates.
• Industrial Control — Industrial temperature rating and low power modes make it suitable for programmable controllers, instrumentation and factory automation devices.
• Consumer & IoT Devices — Fast SPI read speeds and low-power operation support firmware storage and over-the-air update staging in connected devices.
• Code Shadowing & Execution — Uniform sector architecture and reliable endurance enable secure storage of executable code and modular updates without erasing the entire memory.

Unique Advantages

• High-speed SPI Access: 104 MHz operation in single/dual/quad modes delivers fast read throughput for boot and runtime code fetches.
• Granular Erase Control: 4-Kbyte sectors and larger block erase options let designers minimize erase overhead and reduce wear on critical regions.
• Low Idle Power: Typical 1 μA power-down current helps extend battery life and reduces standby energy in embedded systems.
• Robust Endurance & Retention: Designed for a minimum of 100K program/erase cycles per sector and ~20 years data retention for field-proven longevity.
• Hardware & Software Protection: Multiple protection mechanisms including WP# pin and software-protected regions guard against accidental or malicious writes.
• Compact Industrial Packaging: 8-pin SOP 150 mil surface-mount package with industrial temperature range enables space-efficient board designs for harsh environments.
