The introduced MCU family combines the performance of the Cortex-M4 processor with a Floating Point Unit (FPU). Running at up to 120 MHz, the MCUs feature up to 1 MiB of dual-panel flash memory with Error Correction Code (ECC). Additionally, these families are available with up to 256 KiB of SRAM with ECC, vital to mission-critical applications such as medical devices or server systems.

The products have multiple interfaces that provide design flexibility for connectivity needs. They include a Quad Serial Peripheral Interface (QSPI) with an Execute-in-Place (XIP) feature. This allows the application to use high-performance serial flash memories, which are both small and inexpensive compared to traditional pin-parallel flash memory. The micro-controllers also feature the Secure Digital Host Controller (SDHC) for data logging, the Peripheral Touch Controller (PTC) for capacitive touch capabilities, and active power performance (65 µA/MHz). Additionally, the MCUs provide two CAN FD ports and one 10/100-Mbit/s Ethernet Media Access Controller (MAC) with IEEE 1588 support. This makes the products suitable for industrial automation, connected home, and other Internet of Things (IoT) applications.

Additionally, the MCUs provide cryptographic hardware and software support, enabling developers to incorporate security measures at a design’s inception. Hardware-based security features include the Public Key Cryptographic Controller (PUKCC) supporting Elliptic Curve Cryptography (ECC) and RSA schemes as well as the Advanced Encryption Standard (AES) cipher and the 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 working with Microchip. “The SAM E5x micro-controllers provide an excellent migration path for developers wanting a cost-effective solution with powerful performance, comprehensive interface options and built-in security.”

The SAM E54 Xplained Pro Evaluation Kit is available to kick-start development. The kit incorporates an on-board debugger, as well as additional peripherals. The Atmel Studio 7 Integrated Development Environment (IDE) supports the launched MCUs. With the Atmel Start on-line tool the user can configure the peripherals including the CAN FD controllers.
