EN25QH128A-104HIP(2T)

The EN25QH128A-104HIP(2T) is a 128 Megabit serial NOR flash memory device implementing a Serial Peripheral Interface (SPI) architecture. It provides single, dual and quad SPI modes with high-performance read at up to 104 MHz, targeting embedded systems that require non-volatile code and data storage with hardware and software protection mechanisms.

Designed for industrial use, the device supports uniform 4KB sectors, flexible block/sector erase, and fast program/erase operations, making it suitable for firmware storage, field updates and protected data regions in industrial and embedded applications.

Key Features

• Memory Capacity and Organization — 128 Mbit (16,384 KByte) organized as 16M × 8 with 256-byte programmable pages and 4KB uniform sectors for fine-grained erase and program control.
• SPI Interface and Performance — Supports Standard, Dual and Quad SPI modes with SPI clock frequencies up to 104 MHz (Standard/Dual: 104 MHz with 1 dummy byte; Quad: 104 MHz with 3 dummy bytes) for high-speed read operations.
• Program/Erase Performance — Typical page program time 0.5 ms; sector erase 40 ms typical; half-block and block erase times and full chip erase capability included for flexible memory management.
• Power and Low-Power States — Low active and standby currents with typical active current around 5 mA and typical power-down current around 1 µA to conserve system power.
• Robust Protection and Security — Software and hardware write protection, WP# pin support, software/hardware reset, and a lockable 512-byte OTP security sector to protect critical code and data.
• Industrial Grade and Package Options — Industrial temperature range (−40 °C to 85 °C) and available in 8-pin SOP 200 mil package among other package options for space-constrained board designs.
• Reliability — Designed for a minimum of 100K program/erase cycles per sector and typical data retention of 20 years.

Typical Applications

• Embedded Firmware Storage — Store boot code and firmware images with sector-level protection and fast page programming for updates and patches.
• Field Upgrades and In-System Programming — Support in-field firmware updates using SPI interfaces and write-protect mechanisms to safeguard remaining code.
• Industrial Control and Automation — Non-volatile storage for configuration, calibration data, and code in industrial equipment operating across −40 °C to 85 °C.
• Communications and Networking Equipment — Store device firmware and configuration tables with reliable erase/program cycles and low-power standby for energy-efficient designs.

Unique Advantages

• High-speed SPI Operation: Up to 104 MHz SPI clock and quad-output capability enable fast read throughput for code execute-in-place and fast boot scenarios.
• Flexible Interface Modes: Standard, Dual and Quad SPI support lets designers choose the right trade-off between pin usage and bandwidth.
• Granular Erase Architecture: 4KB uniform sectors and multiple block sizes allow precise memory management and targeted updates without full-chip erase.
• Comprehensive Protection: Hardware WP# and software protection features plus a lockable OTP sector reduce risk of accidental or unauthorized memory modification.
• Industrial Temperature Range: Operation from −40 °C to 85 °C suits demanding environments where thermal robustness is required.
• Low Power Consumption: Typical active and power-down currents help minimize overall system power draw during operation and standby.
