EN25SE32A-80GIP(2P)

The EN25SE32A-80GIP(2P) is a 33.55 Mbit non-volatile SPI NOR flash memory organized as 4M × 8. It implements a serial SPI architecture with Standard, Dual and Quad SPI modes and an 80 MHz clock rate to deliver fast read throughput and flexible interface options for embedded code and data storage.

Designed for industrial applications, this surface-mount device is available in an 8-pin SOP 150 mil package and supports an operating temperature range of -40 °C to 85 °C. The device includes uniform 4 KByte sectors, comprehensive write protection and low-power modes for efficient system integration.

Key Features

• Memory and Organization — 33.55 Mbit capacity organized as 4M × 8 with 4096 KByte total; 256-byte programmable page size for granular programming.
• Serial Flash Interface — SPI-compatible Standard/Dual/Quad modes with support for SPI Mode 0 and Mode 3; standard signal set includes CLK, CS#, DI/DO (DQ0/DQ1), WP# and HOLD#.
• Performance — 80 MHz clock rate for Standard, Dual and Quad SPI operation; typical page program time of 1 ms and typical sector erase time of 100 ms (series typical timings included).
• Power — Specified supply voltage 2.5 V; low operating currents with typical active current ~10 mA and typical power-down current ~1 µA (series typical values).
• Erase and Endurance — Uniform sector architecture with 4 KByte sectors, 32 KByte and 64 KByte block options; minimum 100K program/erase cycles per sector and typical data retention of 20 years.
• Write Protection and Security — Software and hardware write protection, WP# pin enable/disable, lockable 3 × 1024-byte OTP security sector, and Read Unique ID capability.
• Package and Operating Range — Surface-mount 8-pin SOP 150 mil package; industrial temperature range -40 °C to 85 °C; RoHS compliant.

Typical Applications

• Firmware and Boot Code Storage — Maintain application firmware and boot code with sector-level erase and page program support for field updates and reliable boot storage.
• Code Patching and Field Upgrades — Uniform 4 KByte sectors and write-protect mechanisms enable selective code patching and secure firmware updates.
• Configuration and Non-Volatile Data — Store configuration tables, calibration data or small data logs with endurance and long-term retention characteristics.

Unique Advantages

• Flexible SPI Modes — Standard, Dual and Quad SPI support plus configurable dummy cycles let designers balance throughput and pin usage according to system needs.
• Granular Erase and Program Control — Uniform 4 KByte sectors and block/half-block/chip erase options let you optimize update size and time for in-field changes.
• Built-In Protection and Security — Hardware WP# and software protection features alongside a lockable OTP sector reduce risk of accidental or unauthorized modification.
• Industrial Temperature Coverage — Rated for -40 °C to 85 °C operation to meet the thermal requirements of industrial and harsh-environment designs.
• Low Power Standby — Typical power-down current around 1 µA helps minimize energy use in battery-powered or always-on systems.
