EN25SX128A-104WIP(2P)

The EN25SX128A-104WIP(2P) is a serial SPI NOR non-volatile memory device in an industrial-grade surface-mount package. It provides a 16M × 8 memory organization (listed memory size 134.2 Mbit) with a serial SPI architecture optimized for fast read operations and flexible I/O modes.

Designed for embedded and industrial systems, this device combines high read throughput (104 MHz fast read capability), low-power modes, and hardware/software write protection to support firmware storage, field upgrades, and secure data segments in space- and cost-constrained designs.

Key Features

• Memory Core  16M × 8 organization with a listed memory size of 134.2 Mbit and non-volatile NOR flash architecture for code and data storage.
• Serial SPI Interface  SPI NOR Flash topology supporting Standard, Dual and Quad SPI I/O modes as described in the product series documentation; flexible dummy-cycle configuration for optimized read timing.
• High-Speed Read  Designed for fast read performance with a 104 MHz clock rate for Single/Dual/Quad I/O Fast Read and an access time of 8 ns.
• Program & Erase Performance  Page program capability (datasheet notes typical page program time ~0.6 ms) and multiple erase granularities including 4K-byte uniform sectors and larger blocks for targeted updates.
• Power & Voltage  Single power-supply operation. Product data lists a 2.5 V supply; the series datasheet specifies a full operating range (1.65–1.95 V) for serial operation modes.
• Low Power  Low active and standby currents are documented in the series datasheet (typical active current ~5 mA; typical power-down current ~3 μA) to support energy-conscious designs.
• Reliability & Security  Endurance and retention characteristics from the series include a minimum of 100k program/erase cycles and typical data retention up to 20 years; hardware and software write-protect features and lockable OTP region are supported.
• Package & Temperature  8-pin WSON 5×6 mm surface-mount package; listed operating temperature in product specifications is −40 °C to 85 °C, with series documentation indicating industrial range up to −40 °C to 105 °C.

Typical Applications

• Embedded Firmware Storage  Non-volatile program storage and code shadowing for microcontrollers and system controllers where serial flash is required.
• Industrial Control  Storage of configuration, firmware and field-upgrade images in industrial equipment benefiting from the device’s industrial-grade packaging and protection features.
• Field Upgrade & Boot Media  Secure, block-level erase and program capabilities allow targeted firmware updates and recovery partitions for remote or in-field serviceability.
• Low-Power Edge Devices  Low standby and active current characteristics make the device suitable for power-sensitive embedded modules that require persistent storage.

Unique Advantages

• Fast Serial Read Performance: 104 MHz fast read capability and 8 ns access time enable responsive code fetch and fast boot times.
• Flexible SPI Modes: Support for Standard, Dual and Quad SPI I/O modes provides design flexibility for throughput versus pin-count trade-offs.
• Granular Erase & Protection: Uniform 4 KB sectors plus larger block erase options and combined hardware/software write protection simplify secure update workflows.
• Low Power Operation: Documented low active and power-down currents reduce energy consumption in battery-backed and always-on systems.
• Industrial-Grade Packaging: Surface-mount 8-pin WSON (5×6 mm) package and industrial temperature range support compact, rugged designs.
