EN25QH32B-104FIP(2C)

The EN25QH32B-104FIP(2C) is a 32 Mbit serial NOR Flash memory device using an SPI-compatible serial interface with Standard, Dual and Quad I/O options. Designed for industrial-temperature embedded storage, it delivers high read/write performance, low-power standby and flexible protection features for firmware, code shadowing and data storage in constrained designs.

Built for systems requiring high throughput and granular memory management, the device supports up to 104 MHz SPI clock, uniform 4 KB sectors and multiple erase/program options to optimize update and retention strategies.

Key Features

• Memory Capacity & Organization — 32 Mbit (4,096 K‑byte) memory organized into 16,384 pages (256 bytes per page) with a uniform sector architecture: 1,024 × 4 KB sectors, 128 × 32 KB blocks and 64 × 64 KB blocks.
• High‑Performance SPI Interface — SPI compatible (Mode 0 and Mode 3) with Standard, Dual and Quad SPI support and a 104 MHz clock rate for Standard, Dual-bit and Quad-bit operations.
• Program & Erase Performance — Typical page program time 0.5 ms; sector erase typically 50 ms; 32 KB/64 KB block erase and full chip erase timing provided for fast maintenance operations.
• Endurance & Data Retention — Minimum 100K program/erase cycles per sector/block and 20 years data retention as specified for long‑term reliability.
• Power & Supply — Single power supply operation with full voltage range 2.7–3.6 V and low-power modes: typical active current ~5 mA and typical power‑down current ~1 μA.
• Protection & Security — Software and hardware write protection (WP# pin), three sets of OTP lockable 512‑byte security sectors, and ability to read Unique ID Number for device identification.
• Package & Temperature — Industrial temperature range (−40 °C to 85 °C) in a 16‑pin SOP 300 mil surface-mount package; additional package options are supported in the series.
• Standards & Discoverability — Supports Serial Flash Discoverable Parameters (SFDP) for host interrogation and flexible system integration.

Typical Applications

• Industrial Control — Reliable non‑volatile storage for firmware, parameter tables and field updates in PLCs, motor drives and factory automation controllers operating across industrial temperature ranges.
• Embedded Systems & IoT Gateways — Code storage and boot images for microcontroller-based devices, gateways and edge modules requiring fast SPI read performance and low standby current.
• Networking & Communications — Firmware storage and configuration memory for routers, switches and wireless modules where fast boot and field upgrade capability are required.
• Consumer & Appliance Electronics — Non‑volatile storage for UI firmware, configuration data and OTA update storage in appliances and smart devices that benefit from granular erase and low-power modes.

Unique Advantages

• Flexible I/O Options: Standard, Dual and Quad SPI support enables designers to scale throughput without changing core memory topology.
• Granular Erase Architecture: 4 KB uniform sectors and multiple block sizes allow targeted updates and reduce erase time and wear on unused regions.
• Fast Read/Program Timing: 104 MHz clock plus typical 0.5 ms page program time gives responsive read/write behavior for firmware and data operations.
• Industrial Reliability: Specified for −40 °C to 85 °C operation with 100K program/erase cycles and 20‑year retention to support long lifecycles in deployed equipment.
• Low Power Operation: Typical active and power‑down currents enable energy‑efficient designs and extended battery or standby life.
• Security & Device Identification: OTP lockable regions and Unique ID read capability support secure storage and inventory management.
