The SAM D5x and SAM E5x microcontroller (MCU) families are now available from Microchip Technology Inc. These new 32-bit MCU families offer extensive connectivity interfaces, powerful performance and robust hardware-based security for a wide variety of applications.

The SAM D5/E5 microcontrollers 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 120 MHz, the D5x and E5x MCUs feature up to 1 MB 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 256 KB of SRAM with ECC, vital to mission-critical applications such as medical devices or server systems.

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 (65 uA/MHz) for applications requiring power efficiency. Additionally, the SAM E5 family includes two CAN-FD ports and a 10/100Mbps 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.

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).

“Applications are becoming increasingly complex and there is a great need to move to faster MCUs with better connectivity options and flexible peripheral support,” said Rod Drake, vice president of Microchip’s MCU32 business unit. “The SAM D5/E5 microcontrollers provide an excellent migration path for developers wanting a cost-effective solution with powerful performance, comprehensive interface options and built-in security.”
