EN25S20A-104RBIP(2SF)

The EN25S20A-104RBIP(2SF) is a 2 Mbit (256 KByte) serial NOR flash memory organized as 256K × 8 and designed for SPI-based memory applications. It implements a Serial Peripheral Interface (SPI) architecture with Standard, Dual and Quad SPI support and delivers high-speed reads at up to 104 MHz.

Engineered for industrial use, the device combines fast access, flexible erase/program options and hardware/software protection features to store firmware, configuration data and security-critical blocks across a −40 °C to 85 °C operating range.

Key Features

• Memory Core & Organization 2 Mbit (256 KByte) storage organized as 256K × 8 with 256‑byte programmable pages and 1024 pages total.
• SPI Interface & Modes Serial interface architecture compatible with Standard SPI (Mode 0/3), Dual and Quad I/O. Standard pin set includes CLK, CS#, DI, DO, WP# and HOLD#.
• High‑Speed Performance Supports a 104 MHz clock rate for single-bit transfers and equivalent up to 416 MHz for quad transfers when using Dual/Quad fast read instructions; includes 8 ns access time.
• Program & Erase Performance Page program typical 0.30 ms; sector erase typical 40 ms; 32 KB block erase typical 100 ms; 64 KB block erase typical 150 ms; full chip erase typical 1 second.
• Memory Architecture Uniform sector architecture: 64 × 4 KB sectors, 8 × 32 KB blocks and 4 × 64 KB blocks allowing individual sector or block erase.
• Power & Low‑Power Modes Typical active current ~6 mA and typical power‑down current ~0.1 μA for energy-conscious designs.
• Protection & Security Software and hardware write protection (WP# pin), lockable 512‑byte OTP security sector, and write suspend/resume features to protect critical areas.
• Reliability & Endurance Minimum 100K program/erase cycles per sector and nominal data retention of 20 years.
• Package & Industrial Grade Surface-mount 8‑pin VSOP (150 mil) option and industrial temperature range −40 °C to 85 °C; RoHS compliant.

Typical Applications

• Industrial Control & Automation Store firmware, configuration and calibration data with industrial temperature range and sector-level erase flexibility.
• Embedded Systems & Microcontroller Boot Host boot code and application firmware in a compact 2 Mbit SPI NOR device with fast read performance and page program capability.
• Secure Data Storage Use the lockable 512‑byte OTP sector and hardware/software protection to safeguard small security keys or configuration parameters.
• Consumer & IoT Devices Provide reliable non‑volatile storage for firmware images, configuration and firmware updates using Standard/Dual/Quad SPI modes.

Unique Advantages

• Flexible SPI Modes: Single, Dual and Quad I/O support enables designers to balance pin count and throughput for a wide range of system requirements.
• Fast Read Performance: 104 MHz clock operation and burst modes (8/16/32/64 with wrap) allow low-latency code execution and rapid data readback.
• Granular Erase Architecture: 4 KB sectors and larger block options let you erase only the needed regions, reducing erase time and wear on remaining data.
• Low Power Standby: Sub‑microampere power‑down current minimizes standby energy use for battery‑sensitive designs.
• Industrial Reliability: Designed for −40 °C to 85 °C operation with minimum 100K program/erase cycles and 20‑year data retention for long-lived deployments.
• Compact Surface‑Mount Package: 8‑pin VSOP (150 mil) package simplifies PCB layout and keeps board area small.
