EN25Q40B-104GIP(2X)

The EN25Q40B-104GIP(2X) is a 4 Mbit (512 K‑byte) serial NOR Flash memory designed for industrial embedded systems. It implements a Serial Peripheral Interface (Standard/Dual/Quad SPI) architecture and supports high-speed read and I/O modes with up to 104 MHz SPI clocking.

Targeted at applications that require compact non‑volatile code and data storage, this device delivers fast read performance, fine‑grained erase and program control, hardware and software write protection, and an extended operating temperature range for industrial use.

Key Features

• Memory & Organization 4 Mbit capacity organized as 512K × 8 (512 K‑byte). Memory is arranged in 2,048 pages with 256 bytes per programmable page.
• Uniform Sector Architecture 128 sectors of 4 Kbyte, 16 blocks of 32 Kbyte and 8 blocks of 64 Kbyte allow single‑sector, block or full chip erase operations.
• High‑Speed Serial Interface SPI compatible (Mode 0 and Mode 3) with Standard, Dual and Quad SPI support. Standard, Dual and Quad I/O modes operate with a 104 MHz clock rate; Dual and Quad modes provide equivalent higher‑throughput operation.
• Program & Erase Performance Page program up to 256 bytes (typical page program time 0.5 ms). Typical sector erase time 40 ms; 32 Kbyte block erase ~0.12 s; 64 Kbyte block erase ~0.15 s; chip erase ~2 s (typical).
• Low Power Typical active current 5 mA and typical power‑down current 1 µA support low‑power embedded designs.
• Supply Voltage Single power supply operation over a full voltage range of 2.3–3.6 V.
• Endurance & Data Retention Minimum 100K program/erase cycles per sector and typical data retention of 20 years.
• Write Protection & Security Software and hardware write protection with WP# pin, plus three lockable 512‑byte OTP security sectors and Read Unique ID capability.
• Package & Temperature Available in an 8‑lead SOP (150 mil) package; industrial operating temperature range −40 °C to 85 °C. RoHS compliant.

Typical Applications

• Industrial Control Stores firmware, configuration and calibration data for controllers and PLCs where industrial temperature range and endurance are required.
• Embedded Systems Provides compact non‑volatile code and parameter storage in microcontroller‑based designs using standard SPI interfaces.
• IoT & Edge Devices Supplies low‑power, high‑speed boot and application code storage with Dual/Quad SPI options for accelerated read performance.
• Consumer & Portable Electronics Useful for storing device firmware, settings and small data logs in space‑constrained 8‑pin packages.

Unique Advantages

• Flexible high‑speed I/O modes: Standard, Dual and Quad SPI at up to 104 MHz enable designers to trade pin count for throughput as needed.
• Fine‑grained memory control: 4 Kbyte uniform sectors and multiple block sizes let you erase and update only the data you need, reducing program/erase cycles on other areas.
• Compact industrial package: 8‑pin SOP (150 mil) package delivers non‑volatile storage in a small footprint while supporting −40 °C to 85 °C operation.
• Low standby and active currents: Typical 1 µA power‑down current and 5 mA active current help minimize system power consumption.
• Security and protection features: Hardware WP# and software protection options plus lockable OTP sectors provide layered safeguards for critical data.
