EN25Q40A-104HIP(2C)

The EN25Q40A-104HIP(2C) is a 4 Mbit (512 K-byte) serial NOR flash memory in the ESMT EN25Q40A series. It implements a SPI serial interface with Standard, Dual and Quad modes and supports high-speed clock rates up to 104 MHz.

Designed for industrial applications, the device provides uniform 4-Kbyte sectors, hardware and software write protection, low-power modes and extended data retention and endurance characteristics that support robust code and non-volatile data storage in temperature-critical environments.

Key Features

• Memory & Organization — 4 Mbit (4,194 Kbit / 512 K-byte) organized as 512K × 8 with 256-byte programmable pages and 4-Kbyte uniform sectors; supports individual sector/block erase.
• Serial SPI Architecture — SPI compatible (Modes 0 and 3) with Standard, Dual and Quad SPI operation and support for Dual/Quad I/O and Fast Read instructions.
• High-Speed Operation — 104 MHz clock rate for Standard SPI and equivalent higher-rate transfer using Dual (×2) or Quad (×4) modes.
• Program / Erase Performance — Typical page program time 0.8 ms; typical sector erase 30 ms, 32 KB block erase 100 ms, 64 KB block erase 200 ms and chip erase 1.5 seconds (typical).
• Endurance & Retention — Minimum 100K program/erase cycles per sector/block and data retention of 20 years.
• Low Power — Typical active current ~10 mA and deep power-down current ~1 µA for reduced power consumption in standby.
• Write Protection & Security — Software and hardware write protection, WP# pin to enable/disable protection, and a lockable 512-byte OTP security sector; supports Read Unique ID and SFDP signature.
• Supply & Operating Range — Full voltage range 2.4–3.6 V and industrial operating temperature range −40 °C to 85 °C.
• Package & Mounting — 8-pin SOP 200 mil package, surface-mount mounting; RoHS compliant.
• Access Time — 8 ns access time (device summary specification).

Typical Applications

• Industrial Control — Non-volatile storage of firmware, configuration and system parameters for industrial automation and control equipment operating across a −40 °C to 85 °C range.
• Embedded Systems — Code and data storage for microcontroller-based designs requiring SPI NOR memory with sector-level erase and page programming.
• Security & Identification — Lockable 512-byte OTP sector and Read Unique ID capabilities for device identification, secure configuration and calibration storage.

Unique Advantages

• High-throughput SPI interface — 104 MHz standard SPI with Dual/Quad options enables faster code and data transfer when higher throughput is required.
• Flexible erase and program granularity — Uniform 4-Kbyte sectors and multiple block sizes allow targeted updates without full-chip erase.
• Robust endurance and retention — Minimum 100K program/erase cycles and 20-year data retention support long-lived deployments and reliable field operation.
• Hardware and software protection — WP# pin plus software-controlled protection reduce risk of unintended writes to critical regions.
• Low-power standby — Deep power-down current in the microamp range helps reduce system power when flash access is not required.
• Industrial temperature and RoHS compliance — Wide operating temperature range and lead-free packaging suitable for industrial-grade designs and compliant manufacturing.
