EN25QE16A-104XBIP(2P)

The EN25QE16A-104XBIP(2P) is a 16.78 Mbit non-volatile SPI NOR Flash memory in an industrial-grade surface-mount package. Built on SPI NOR architecture with a high-speed 104 MHz clock capability, it is optimized for code and data storage in embedded and industrial applications that require uniform sectors, robust protection and long data retention.

With a compact 8‑pin USON 4×3 mm package and an industrial operating temperature range, this device delivers high performance, flexible read/write modes (Standard/Dual/Quad SPI), and embedded protection features to support firmware storage, update and secure data regions.

Key Features

• Memory Capacity & Organization — 16.78 Mbit total capacity organized as 2M × 8 (2048 KByte) with 8192 pages and 256 bytes per programmable page for fine-grained writes.
• High-Speed SPI Performance — 104 MHz clock rate for Standard, Dual and Quad SPI modes enabling fast read throughput for code execution and large-data transfers.
• Uniform Sector Architecture — 512 uniform 4-KByte sectors, 64 blocks of 32-KByte and 32 blocks of 64-KByte; any sector or block can be erased individually for flexible memory management.
• Program and Erase Performance — Typical page program time and erase timings provided in the device datasheet; supports page program operations up to 256 bytes per operation.
• Low Power — Low active and standby power characteristics are documented in the datasheet to support power-sensitive embedded designs.
• Protection and Security — Software and hardware write protection options, WP# pin control, configurable protection for blocks, lockable 3×1024 byte OTP security sector and Read Unique ID Number support.
• Endurance & Retention — Minimum 100K program/erase cycles per sector and 20 years data retention as specified in the product documentation.
• Package & Temperature — Surface-mount 8-pin USON 4×3 mm package; industrial-grade operating temperature range of -40 °C to 85 °C.
• Standards & Discoverability — Supports Serial Flash Discoverable Parameters (SFDP) signature for device identification and compatibility in SPI flash ecosystems.

Typical Applications

• Embedded Systems — Stores firmware and application code where fast execute-in-place (XIP) read performance and uniform sector erase are required.
• Industrial Control — Retains configuration and operational parameters with industrial temperature range and long data retention.
• Field Firmware Updates — Supports reliable in-field updates and code patching via individually erasable sectors and software/hardware write protection.
• Security & ID Storage — Lockable OTP sector and Read Unique ID enable secure storage of calibration data, device IDs or small secrets.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI at up to 104 MHz let you optimize throughput for both reads and multi-bit transfers without changing package or pinout.
• Fine-Grained Erase Control: Uniform 4-KByte sectors and multiple block sizes allow targeted updates and reduced erase overhead during firmware changes.
• Robust Data Longevity: Specified endurance of 100K cycles and 20 years data retention support long-life deployments and maintenance cycles.
• Compact Industrial Packaging: 8‑pin USON 4×3 mm surface-mount package saves PCB area while meeting industrial temperature requirements.
• Integrated Protection Mechanisms: Software and hardware write protection, WP# control and a lockable OTP sector reduce risk of accidental or unauthorized modifications.
• Device Discoverability: SFDP support and Read Unique ID simplify system integration and firmware management across product variants.
