EN25S10A-104RBIP(2SQ)

The EN25S10A-104RBIP(2SQ) from ESMT is a 1 Mbit serial SPI NOR flash memory organized as 128K × 8. It implements a serial SPI architecture with Standard, Dual and Quad SPI modes and supports high-speed read operations up to a 104 MHz clock rate.

Designed for embedded code and data storage in industrial applications, the device combines flexible program/erase control, uniform 4 Kbyte sectors, hardware and software write protection, and low-power standby characteristics for efficient system integration.

Key Features

• Memory Capacity & Organization — 1 Mbit total capacity organized as 128K × 8 with 512 pages of 256 bytes per page, suitable for firmware, configuration and small data storage segments.
• Serial SPI Interface — SPI compatible (Mode 0 and Mode 3) with support for Standard, Dual and Quad I/O. Clock rates up to 104 MHz for single, dual and quad-bit transfers.
• Uniform Sector Architecture — 32 × 4-Kbyte sectors plus 4 × 32-Kbyte and 2 × 64-Kbyte blocks; sectors and blocks can be erased individually to enable targeted updates.
• Program & Erase Performance — Page program capability (up to 256 bytes per page); typical page program and erase timings provided in the datasheet (page program time and sector/block erase times detailed in product documentation).
• Protection & Security — Software and hardware write protection options with WP# pin, write suspend/resume, and a lockable 512-byte OTP security sector.
• Low Power — Typical active current and low-power standby performance noted in the datasheet (typical low-power standby current in the microamp range).
• Package & Mounting — Surface-mount 8-pin VSOP 150mil body width package (also available in other 8‑contact package options per datasheet).
• Industrial Temperature Range — Specified operating temperature range of −40 °C to +85 °C for deployment in industrial environments.
• Reliability — Minimum endurance of 100K program/erase cycles per sector and data retention rated at 20 years (per datasheet specifications).
• Standards & Discoverability — Supports Serial Flash Discoverable Parameters (SFDP) and Read Unique ID functionality (see datasheet note for additional details).

Typical Applications

• Industrial Control & Automation — Non-volatile storage for firmware, configuration blocks, and field updates in industrial controllers and instrumentation.
• Embedded Systems & IoT Devices — Firmware and parameter storage where compact footprint and SPI bus access are required.
• Code Storage & Field Upgrades — Storage for boot code, patchable modules and subroutines with sector-level erase and write-protection for safe updates.
• Consumer & Appliance Firmware — Small-footprint flash for firmware and calibration data in appliances and consumer electronics within industrial temperature requirements.

Unique Advantages

• Flexible I/O Modes: Standard, Dual and Quad SPI support with up to 104 MHz clocking enables higher effective throughput when using Dual/Quad modes.
• Granular Erase Architecture: Uniform 4-Kbyte sectors and multiple block sizes allow targeted updates and reduce the need for wide-range erase operations.
• Robust Protection Mechanisms: Combined software and hardware write protection and a lockable OTP sector help safeguard critical code and data.
• Industrial-Grade Operation: Specified for −40 °C to +85 °C operation, meeting temperature demands of industrial deployments.
• Compact SMD Package: 8-pin VSOP 150mil surface-mount package minimizes board space impact while supporting standard assembly processes.
• Long-Term Reliability: Minimum 100K program/erase cycles and 20-year data retention provide endurance and longevity for deployed systems.
