EN25QW16A-104WIP(2P)

The EN25QW16A-104WIP(2P) is a 16 Mbit serial NOR Flash memory device offering a wide supply voltage range and a serial SPI interface architecture. Designed for industrial-grade embedded storage, it provides uniform 4 Kbyte sectors, flexible erase/program operations and multiple SPI modes (standard, dual and quad) for scalable throughput.

This device targets industrial and embedded applications that require non-volatile code and data storage with configurable protection, low-power standby and a compact 8-contact VDFN/WSON (6×5 mm) package across an operating range of -40°C to +85°C.

Key Features

• Memory and Organization 16 M-bit (2,048 KByte) capacity organized as 2M × 8 with 256-byte programmable pages and 4 Kbyte uniform sectors (512 sectors total).
• Interface and Modes SPI compatible architecture supporting Standard, Dual and Quad SPI. Standard SPI pins include CLK, CS#, DI, DO, WP# and HOLD#; Quad and Dual I/O are supported for higher throughput.
• Clock & Performance 104 MHz clock rate supported for Standard, two-bit and four-bit data modes; 12 ns access time for fast read operations.
• Program / Erase Timing Page program time typically 1 ms; sector erase typically 100 ms; half-block 300 ms; block erase 500 ms; full chip erase typically 15 seconds.
• Power Full supply range 1.65 V to 3.6 V. Typical active current around 10 mA and typical power-down current ~1 μA for low-power standby.
• Reliability & Security Minimum 100K program/erase cycles per sector, 20-year data retention, lockable 3 × 1024-byte One-Time-Programmable (OTP) security sector, support for volatile status bits, and Read Unique ID feature.
• Flexible Protection Software and hardware write protection with WP# pin; supports write protection of all or portions of memory and individual sector/block protection with write suspend/resume.
• Standards & Discoverability Supports Serial Flash Discoverable Parameters (SFDP) signature for device parameter discovery.
• Package & Temperature 8-contact VDFN/WSON package (6×5 mm) in an industrial temperature grade from -40°C to +85°C; RoHS-compliant, Pb-free packaging.

Typical Applications

• Embedded Firmware Storage Persistent storage for boot code, firmware images and configuration data where sector-level erase and page programming are required for field updates.
• Field Upgrades & Patchable Code Use in systems that require selective block or sector updates—unprotect specific regions for modification while keeping other regions protected.
• Industrial Control & Instrumentation Non-volatile code and parameter storage for industrial controllers and instrumentation within the device’s -40°C to +85°C operating range.
• Data Logging & Configuration Storage Storage of calibration data, device configuration and small data logs with endurance and retention characteristics suitable for long-term use.

Unique Advantages

• Wide Supply Voltage Range: Operates from 1.65 V to 3.6 V, enabling flexibility across power domains and single-supply designs.
• Multi-Mode SPI Throughput: Standard, Dual and Quad SPI support with a 104 MHz clock rate enables scalable read/write bandwidth without changing the memory architecture.
• Compact Industrial Package: 8-contact VDFN/WSON (6×5 mm) footprint suits space-constrained PCBs while meeting industrial temperature requirements.
• Granular Erase & Protection: 4 Kbyte uniform sectors, individual sector/block erase and software/hardware protection make firmware management and secure updates straightforward.
• Low Power Standby: Typical 1 μA power-down current reduces standby energy use in battery-assisted or low-power systems.
• Long-Term Reliability: Specified minimum 100K program/erase cycles and 20-year data retention for durable field operation.
