EN25QW32A-104HIP(2P)

The EN25QW32A-104HIP(2P) from ESMT is a 32 Megabit serial NOR Flash memory device in the EN25QW32A series, optimized for wide voltage operation and industrial temperature ranges. It uses a Serial Peripheral Interface (SPI) architecture with support for Standard, Dual and Quad SPI modes and is supplied in an 8-lead SOP (200 mil) surface-mount package.

This device is targeted at embedded and industrial applications requiring non-volatile code and data storage with flexible protection, high-speed serial access and low-power standby behavior. Key value propositions include wide supply range (1.65–3.6 V), high-speed SPI operation (up to 104 MHz), and uniform-sector erase architecture for granular memory management.

Key Features

• Memory Type & Capacity  32 M-bit (4,096 Kbyte) NOR Flash organized as 4M × 8 with 256-byte programmable pages.
• Interface & Modes  SPI serial interface compatible with Mode 0 and Mode 3; supports Standard, Dual and Quad SPI (CLK, CS#, DI/DO, DQ₂/WP#, DQ₃/HOLD#).
• Performance  High-performance serial read/write with a 104 MHz clock rate for Standard, two-bit and four-bit data transfer; access time listed at 12 ns.
• Program / Erase  Page program time and erase timing optimized for firmware/data updates: typical page program time 1 ms, sector erase ~100 ms, block erase options and full chip erase ~30 s (typical values from device datasheet).
• Voltage & Power  Wide supply voltage range 1.65 V to 3.6 V; low power consumption with typical active current around 10 mA and typical power-down current near 1 µA.
• Sector & Block Architecture  Uniform Sector Architecture with 4-Kbyte sectors (1,024 sectors), 32-Kbyte and 64-Kbyte block options for flexible erase and update granularity.
• Reliability & Security  Minimum 100K program/erase cycles per sector and 20-year data retention; lockable 3 × 1024-byte OTP security sector, Serial Flash Discoverable Parameters (SFDP) support and unique ID read capability.
• Protection & Control  Software and hardware write protection with WP# pin to enable/disable protection; write suspend/resume supported for interrupted operations.
• Package & Temperature  8-pin SOP package (200 mil body width), surface-mount, industrial grade with operating temperature −40°C to +85°C.
• Standards & Compliance  RoHS-compliant Pb-free packaging (as noted in product information).

Typical Applications

• Embedded Firmware Storage  Non-volatile program storage for microcontroller-based systems requiring in-field updates and block-level protection.
• Industrial Control  Configuration and calibration data storage in industrial devices that operate across −40°C to +85°C and require wide voltage tolerance.
• Consumer & IoT Devices  Boot code and resource storage for compact, low-power devices using SPI-based flash memory with dual/quad read options.
• Security & Identification  Device unique ID and lockable OTP area for storing device-specific keys or small secure data segments.

Unique Advantages

• Wide Voltage Support: Operates across 1.65–3.6 V to simplify designs that must support multiple power rails.
• Flexible SPI Modes: Standard, Dual and Quad SPI support at up to 104 MHz enables higher bandwidth reads when needed without changing device family.
• Granular Erase Architecture: 4-Kbyte uniform sectors and multiple block sizes allow targeted updates and reduce erase-induced wear on unrelated code/data.
• Industrial Temperature Range: Specified −40°C to +85°C for reliable operation in demanding environments.
• Low Power Standby: Typical 1 µA power-down current helps minimize standby energy consumption in battery- or energy-conscious designs.
• Robust Lifecycle Metrics: Minimum 100K program/erase cycles and 20-year data retention support long-term product lifecycles and field updates.
