Microchip Technology SAM D5 & E5 32-Bit Arm Cortex-M4F Microcontrollers

Microchip Technology SAM D5 and SAM E5 32-Bit Arm® Cortex®-M4F Microcontrollers offer extensive connectivity interfaces, powerful performance, and robust hardware-based security for a variety of applications. The SAM D5 and SAM E5 MCUs combine the performance of an Arm® Cortex-M4 processor with a Floating Point Unit (FPU). This combination offloads the Central Processing Unit (CPU), increasing system efficiency and enabling process-intensive applications on a low-power platform.

Running at up to 120MHz, the SAM D5 and SAM E5 MCUs feature up to 1MB of dual-panel Flash with Error Correction Code (ECC), easily enabling live updates with no interruption to the running system. Additionally, these families are available with up to 256KB of SRAM with ECC, vital to mission-critical applications such as medical devices or server systems.

These new MCUs have multiple interfaces that provide design flexibility for even the most demanding connectivity needs. Both families include a Quad Serial Peripheral Interface (QSPI) with an Execute in Place (XIP) feature. This allows the system to use high-performance serial Flash memories, which are both small and inexpensive compared to traditional pin parallel Flash, for 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 capacitive touch capabilities, and best-in-class active power performance (65µA/MHz) for applications requiring power efficiency. Additionally, the SAM E5 family includes two CAN-FD ports and a 10/100 Mbps Ethernet Media Access Controller (MAC) with IEEE 1588 support, making it well-suited for industrial automation, connected home, and other Internet of Things (IoT) applications.

Both the SAM D5 and SAM E5 families contain comprehensive cryptographic hardware and software support, enabling developers to incorporate security measures at a design’s inception. Hardware-based security features include a Public Key Cryptographic Controller (PUKCC) supporting Elliptic Curve Cryptography (ECC) and RSA schemes as well as an Advanced Encryption Standard (AES) cipher and Secure Hash Algorithms (SHA).

The Microchip Technology SAM D5 and SAM E5 MCUs are offered in QFN, TQFP, and WLCSP packages, with a variety of pin counts, for design flexibility.
