Microchip adds microcontroller connectivity interface options

The SAM D5/E5 microcontrollers combine the performance of an ARM Cortex-M4 processor with a floating point unit (FPU). This combination offloads the 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), 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.

The new MCUs have multiple interfaces that provide design flexibility. 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 active power performance (65 μA/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 suited for industrial automation, connected home, and other Internet of Things (IoT) applications.

Both the SAM D5x and E5x 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).

“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.”

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, to further ease the design process. All SAM D5x/E5x MCUs are supported by the Atmel Studio 7 Integrated Development Environment (IDE) as well as Atmel START, a free online tool to configure peripherals and software that accelerates development.

SAM D5x and SAM E5x devices are available today in a variety of pin counts and package options in volume production quantities. Devices in the SAM D5/E5 Series are available starting at $2.43 each in 10,000 unit quantities. The SAM E54 Xplained Pro Evaluation Kit is available for $84.99.
