The AT25PE20-SSHN-T is a 2-Mbit serial NOR Flash memory device from Renesas (formerly Adesto), housed in an 8-lead SOIC (150-mil body width) package supplied on tape and reel for automated SMT assembly. It operates over a wide 1.65V to 3.6V supply range, supports a maximum SPI clock frequency of 85 MHz, and is organized as 256K x 8 bits, making it a compact, high-performance non-volatile storage solution for embedded systems.
Key Feature and Application
● Wide Operating Voltage Range: Supports 1.65V to 3.6V single-supply operation, enabling compatibility with modern low-voltage 1.8V and 3.3V microcontroller platforms without level shifters.
● High-Speed SPI Interface: Delivers a maximum clock frequency of 85 MHz, significantly reducing read access latency and improving throughput for firmware booting and data logging tasks.
● Low Active Power Consumption: Draws a maximum active read current of only 15 mA, minimizing power draw in battery-powered and energy-sensitive portable devices.
● Extended Industrial Temperature Range: Guarantees reliable operation from -40°C to +85°C, suitable for harsh industrial, automotive, and outdoor environmental conditions.

This serial Flash is optimized for reliable non-volatile code and data storage. Its primary applications include:
● Embedded Firmware Storage: Stores bootloader, application code, and configuration parameters in microcontroller-based IoT nodes, smart sensors, and industrial control modules.
● Parameter and Data Logging: Serves as a non-volatile buffer for calibration constants, system serial numbers, and small-volume event logs in portable test instruments and medical devices.
● FPGA Configuration Storage: Acts as a dedicated configuration memory for low-to-mid density FPGAs, storing the bitstream that is automatically loaded on power-up.
● Consumer Electronics Peripherals: Used in network interface cards, set-top boxes, and peripheral devices for storing firmware updates and user preference settings.
