EN25SY256A-133HIP(2PC)

The EN25SY256A-133HIP(2PC) is a 256 Mbit serial NOR flash memory device from ESMT designed for industrial embedded applications. It implements a Serial Peripheral Interface (SPI) architecture with Single/Dual/Quad I/O modes and provides high-speed Quad I/O Fast Read operation up to 133 MHz.

With uniform 4 KB sectors, 256‑byte programmable pages and hardware/software protection mechanisms, this device addresses code and data storage needs where in-field updates, block protection and long data retention are required in industrial temperature environments.

Key Features

• Memory Capacity & Organization — 256 Mbit density organized as 32M × 8 with 256 bytes per programmable page and 8,192 uniform 4‑Kbyte sectors.
• Serial SPI Architecture — SPI compatible (Mode 0 and Mode 3) supporting Standard, Dual and Quad SPI I/O with CLK, CS#, DI/DO and DQ₂, DQ₃ for expanded modes.
• High‑speed Read — Quad I/O Fast Read operation up to 133 MHz (104 MHz for Single/Dual I/O Fast Read), enabling fast code and data fetch.
• Program/Erase Performance — Page program up to 256 bytes (0.5 ms typical page program time), sector erase/block erase and full chip erase options for flexible update operations.
• Reliability & Endurance — Minimum 100K program/erase cycles per sector and typical data retention of 20 years.
• Power & Low Power Modes — Low active current (typical 7 mA) and very low power‑down current (typical 1 μA).
• Protection & Security — Software and hardware write protection options, lockable 3 × 512‑byte One‑Time‑Programmable (OTP) security sector, plus volatile status register bits for region protection.
• Voltage Range & Supply — Single power supply operation with full voltage range specified in device documentation at 1.65–1.95 V.
• Package & Temperature — Surface mount packages including 8‑lead SOP (200 mil) body width; industrial operating temperature range −40 °C to 85 °C.
• Standards & Discoverability — Supports Serial Flash Discoverable Parameters (SFDP) and Read Unique ID for system integration and device identification.
• Compliance — RoHS compliant packaging options.

Typical Applications

• Industrial Embedded Systems — Reliable non‑volatile storage for firmware, configuration and field updates across −40 °C to 85 °C operating conditions.
• Firmware Storage & In‑field Updates — Uniform 4 KB sectors and block protection enable safe code patching and partial memory updates without erasing the entire device.
• Boot & Code Execution — High‑speed Quad I/O Fast Read at up to 133 MHz supports rapid code fetch for boot ROM and execute‑in‑place (XIP) use cases.
• Secure Data Segments — Lockable OTP sector and software/hardware protection facilitate protected storage of critical identifiers or configuration data.

Unique Advantages

• High‑performance Quad I/O: 133 MHz Quad I/O Fast Read accelerates code/data access where throughput matters.
• Flexible protection model: Software and hardware write protection plus block‑level control allow selective updates and reduced risk during field programming.
• Long endurance and retention: Minimum 100K program/erase cycles and 20‑year retention support long lifecycles common in industrial deployments.
• Low standby power: Typical 1 μA power‑down current helps minimize energy use in battery‑assisted or low‑power industrial systems.
• Uniform sector architecture: 4 KB uniform sectors simplify partitioning and firmware management for modular updates.
• Package and temperature support: Surface‑mount 8‑lead SOP (200 mil) package and industrial temperature rating facilitate integration into compact PCB designs.
