The SAM D5/E5 series is Microchip’s new generation of 32-bit ARM® Cortex®-M4 high-performance MCUs.
It integrates a floating-point unit, operates at speeds up to 120 MHz/400 CoreMark®, with a maximum of 1 MB Flash and 256 KB SRAM, all featuring secure encryption algorithms. This series has extremely low power consumption and ultra-small packaging, making it suitable for battery-powered and miniaturized device applications.
Multiple Interfaces
These new MCUs come with multiple interfaces, enhancing design flexibility and meeting the demands of even the most stringent connections. This series includes a quad serial peripheral interface (QSPI) with execute-in-place (XIP) capabilities. This allows the system to use high-performance serial flash memory, which is not only smaller but also cheaper compared to traditional pin-parallel flash, fulfilling external memory needs. The SAM D5/E5 devices also feature a secure digital host controller (SDHC) for data logging, a peripheral touch controller (PTC) for implementing capacitive touch functionality, and first-class operating power performance (65 uA/MHz), making it suitable for energy-efficient applications. Furthermore, the SAM E5 series includes two CAN-FD ports and a 10/100 Mbps Ethernet media access controller (MAC) supporting IEEE 1588, making it ideal for industrial automation, home networking, and other Internet of Things (IoT) applications.
Secure and Reliable
The SAM D5 and E5 series both provide comprehensive hardware and software support for encryption, enabling developers to integrate security measures from the start of the design. Hardware-based security features include support for elliptic curve cryptography (ECC) and RSA schemes via a public key cryptography controller (PUKCC), as well as Advanced Encryption Standard (AES) encryption and Secure Hash Algorithm (SHA). The SAM D5/E5 microcontrollers, with their powerful performance, rich interfaces, and built-in security features, can effectively meet the design requirements of various applications.

Development Tool Support
Atmel Studio 7
Atmel Studio 7 is available for free and integrates the Atmel Software Framework (ASF). ASF is a large free source code library containing 1600 project examples. ASF enriches the functionality of Atmel Studio — allowing developers to access ready-to-use code in the same environment, minimizing some of the preliminary design work for projects. The standard IDE is suitable for creating new software for MCU projects. Additionally, Atmel Studio 7 IDE has the following advantages:
• Facilitates reuse of existing software for differentiated designs.
• Integrated tools and software extensions can be easily accessed through Atmel Gallery, supporting the product development process.
• Advanced features, an extensible software ecosystem, and robust debugging integration can shorten time-to-market.
Atmel START
Atmel START is a web-based software configuration tool launched by Atmel, helping developers reduce the time spent on integrating software components for specific circuit boards and devices, thus accelerating product time-to-market.
