EN25QH16B-104GIP(2A)

The EN25QH16B-104GIP(2A) is a 16 Mbit serial NOR flash memory device implementing a SPI serial architecture with support for Standard, Dual and Quad I/O. It provides uniform 4-Kbyte sectors, flexible erase/program operations and high read throughput for embedded code and data storage.

Designed for industrial temperature operation and low-power modes, this device targets embedded systems and other applications that require non-volatile program/storage with fast SPI read performance and robust program/erase endurance.

Key Features

• Memory Capacity & Organization — 16 Mbit (2,048 K‑byte) organized as 2M × 8 with 8,192 pages of 256 bytes each and 512 uniform 4‑Kbyte sectors.
• SPI Serial Interface — SPI compatible (Mode 0 and Mode 3) with Standard, Dual and Quad SPI support using CLK, CS#, DI (DQ0), DO (DQ1), WP# (DQ2) and HOLD# (DQ3).
• High-Speed Read Performance — Supports serial clock rates up to 104 MHz (enabling equivalent 208 MHz Dual and 416 MHz Quad I/O effective data rates when using Dual/Quad I/O Fast Read instructions).
• Program & Erase Performance — Fast programming and erase: typical page program time 0.6 ms; sector erase ~50 ms; 32 KB block erase ~120 ms; 64 KB block erase ~150 ms; chip erase ~6 s (typical values).
• Endurance & Retention — Minimum 100K program/erase cycles per sector or block with typical data retention of 20 years.
• Power & Voltage — Single power-supply operation with full voltage range 2.3–3.6 V; low power consumption with typical active current ~5 mA and typical power-down current ~1 μA.
• Protection & Security — Uniform sector architecture with software and hardware write protection options, WP# pin control, and three lockable 512‑byte OTP security sectors.
• Package & Temperature — Available in an 8‑lead SOP 150 mil package (surface-mount) and specified for industrial temperature range −40 °C to 85 °C.

Typical Applications

• Industrial Controllers — Non-volatile code and configuration storage for control systems operating across −40 °C to 85 °C.
• Embedded Firmware Storage — Primary or shadow firmware storage where fast SPI reads and page programming are required.
• Consumer & IoT Devices — Firmware, boot code and data storage leveraging Standard/Dual/Quad SPI throughput for faster boot and data access.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support enables designers to trade off pin usage and throughput to match system needs.
• Fast Read Throughput: Up to 104 MHz SPI clock with equivalent higher effective rates in Dual/Quad modes for accelerated code and data fetch.
• Granular Erase Control: 4‑Kbyte uniform sectors and block erase options let designers optimize lifetime and update granularity.
• Low-Power Operation: Typical active current ~5 mA and power-down currents around 1 μA help reduce system standby energy.
• Industrial Temperature Grade: Specified −40 °C to 85 °C for reliable operation in harsh environments.
• Long-Term Data Reliability: 100K program/erase cycles and 20 years data retention support long product lifecycles.
