The EN25QH16A-104GIP(2C) from ESMT is a 16 Megabit serial NOR flash memory device featuring a high-performance SPI architecture with support for Standard, Dual and Quad SPI modes. It delivers fast read performance at up to 104 MHz while providing flexible, uniform-sector erase options and enhanced write-protection mechanisms.

Designed for industrial-grade embedded systems, this surface-mount 8-pin SOP device combines high throughput, low power modes and on-chip protection features to support firmware storage, code shadowing and device identification in temperature-sensitive environments.

Key Features

• Memory & Organization  16 M-bit (2,048 K-byte) capacity organized as 2,048 K-byte / 8,192 pages with 256 bytes per programmable page and a uniform sector architecture (512 × 4‑Kbyte sectors).
• High-Speed SPI Interface  SPI compatible (Mode 0 and Mode 3) with Standard, Dual and Quad SPI support; clock rate up to 104 MHz for Standard, Dual and Quad operations for accelerated read throughput.
• Program / Erase Performance  Typical page program time 0.6 ms; sector erase ~30 ms; 32 KB block erase ~100 ms; 64 KB block erase ~200 ms; chip erase ~6 seconds (typical).
• Low Power  Typical active current ~10 mA and typical power-down current ~1 μA to minimize standby power in battery-assisted or always-on applications.
• Reliability & Data Retention  Minimum 100K program/erase cycles per sector/block and data retention time of 20 years for long-term storage of firmware and configuration data.
• Security & Identification  Lockable 512‑byte OTP security sector plus Read Unique ID capability for basic device identification and small secure storage needs.
• Write Protection  Combined hardware (WP# pin) and software protection options to guard critical regions of flash memory.
• Package & Temperature  Surface-mount 8‑lead SOP (150 mil body width) package; Industrial operating temperature range of -40 °C to 85 °C.
• Standards & Discoverability  Supports Serial Flash Discoverable Parameters (SFDP) signature for standardized flash configuration discovery.

Typical Applications

• Industrial Controls  Non-volatile storage for firmware, configuration and calibration data in controllers and instrumentation operating across -40 °C to 85 °C.
• Embedded Systems  Boot code and firmware storage for microcontroller- or MPU-based designs that require fast, high-efficiency code fetch via SPI, including Dual/Quad modes for higher throughput.
• IoT & Edge Devices  Compact surface-mount footprint and low power modes make it suitable for gateway nodes, sensor hubs and edge devices needing reliable non-volatile storage and device identification.
• Secure ID & Small Data Storage  Use the Read Unique ID and lockable 512‑byte OTP sector for device authentication, serial numbers or secure configuration bits.

Unique Advantages

• Fast, flexible read modes  104 MHz operation across Standard, Dual and Quad SPI enables scalable throughput without changing the underlying memory technology.
• Fine-grained erase control  4‑Kbyte uniform sectors plus 32 KB / 64 KB block options allow efficient erase and update of small or large code/data regions.
• Low standby power  Typical 1 μA power-down current conserves energy in battery-assisted or low-power systems.
• Industrial temperature range  Rated for -40 °C to 85 °C to support harsh-environment and industrial applications.
• Robust endurance and retention  100K program/erase cycles and 20 years data retention provide longevity for deployed products.
• On-chip protection and ID  Hardware WP# pin, software protection options and a unique ID plus lockable OTP enable secure and manageable deployments.
