EN25QH128A (2UC)

The EN25QH128A (2UC) is a 128 M-bit serial NOR Flash memory device in a SPI architecture designed for industrial-grade non-volatile storage. It provides high-performance serial read and program operations with Standard, Dual and Quad SPI support and a 104 MHz SPI clock for fast data transfers.

Targeted at embedded and industrial applications that require reliable firmware and data storage, the device combines uniform 4 KB sectors, flexible protection features, and low-power modes to support in-field updates, code storage and data retention requirements.

Key Features

• Memory Capacity & Organization — 128 M-bit (16,384 KByte) organized as 16M × 8 with 65,535 pages and 256 bytes per programmable page.
• Serial SPI Interface — SPI compatible (Mode 0 and Mode 3) with Standard, Dual and Quad SPI I/O (CLK, CS#, DI/DO, DQ₂, DQ₃) and configurable dummy cycles.
• High Read Performance — Supports up to 104 MHz clock rate for Standard, Dual and Quad SPI, enabling equivalent Quad throughput using four data bits.
• Uniform Sector Architecture — 4,096 uniform sectors of 4 KB; 512 blocks of 32 KB; 256 blocks of 64 KB; allows individual sector or block erase operations.
• Program & Erase Performance — Typical page program time 0.7 ms; typical sector erase time 50 ms; half-block erase 200 ms; block erase 300 ms; chip erase ~70 seconds.
• Reliability & Data Retention — Minimum 100K program/erase cycles per sector/block and 20 years data retention.
• Low Power — Typical active current ~10 mA and typical power-down current ~1 μA for energy-efficient operation.
• Security & Identification — Lockable 512-byte OTP security sector and ability to read a unique ID number; supports Serial Flash Discoverable Parameters (SFDP).
• Single Supply Operation — Full voltage range 2.7–3.6 V for single-supply operation.
• Industrial Temperature Range — Operation specified from -40 °C to 105 °C for extended-environment use.
• Package Options & Mounting — Multiple package options including SOP, VDFN/WSON, TFBGA and USON; surface-mount capable (packages and body sizes listed in the datasheet).
• Standards & Compliance — Pb-free packages compliant with RoHS and REACH requirements.

Typical Applications

• Embedded Systems: Firmware and boot-code storage where fast random read and reliable program/erase cycles are required.
• Industrial Control: Non-volatile storage for configuration, calibration, and firmware updates across an extended temperature range.
• Consumer & IoT Devices: Local program and data storage with low-power standby and wide interface flexibility (Standard/Dual/Quad SPI).
• Networking & Communications Equipment: Storage for firmware images and system parameters with granular sector erase and protection features.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support with a 104 MHz clock allows designers to scale throughput without changing the device family.
• Granular Erase & Protection: 4 KB uniform sectors and software/hardware write protection enable targeted updates and secure storage of critical code segments.
• Strong Endurance & Retention: Minimum 100K program/erase cycles and 20-year data retention provide long-term reliability for fielded systems.
• Low Power Profile: Typical active current ~10 mA and ultra-low power-down current (~1 μA) help minimize energy use in battery-assisted or energy-sensitive designs.
• Industrial Thermal Range: Specified operation from -40 °C to 105 °C supports deployment in harsh and temperature-variable environments.
• Multiple Package Options: Wide selection of surface-mount packages supports diverse PCB and form-factor requirements.
