Infineon targets the complete EV charging ecosystem from AC to high-power DC

Infineon's XMC7000 series of microcontrollers is designed for high-end industrial uses and provides exceptional compute power via single/dual-core Cortex®-M7 and Cortex®-M0+ cores. They feature low-power 40-nm technology, advanced peripherals like CAN FD, TCPWM, and Gigabit Ethernet for enhanced flexibility and connectivity. With operation temperatures from -40°C to 125°C and power-saving modes reaching 8µA, these MCUs offers high reliability in harsh conditions. The series, including XMC7100 and XMC7200, offers security, operates in critical applications, and comes in TQFP/LFBGA packages with 100-272 pins, all catering to dedicated EV Charging requirements.

The PSoC™ 62 performance line, built on an ultra low-power 40-nm platform, is a combination of Arm® Cortex®-M4 and Arm® Cortex®-M0+ CPUs, with low-power Flash technology, programmable digital and analog resources, and best-in-class CAPSENSE™ technology for touch and proximity applications. This highly integrated MCU helps enable the development of advanced EV charging products having a rich and robust HMI, secure cloud connectivity and an intuitive user experience that a smart home connected device should have.

The FM25V02A-G as a non-volatile memory with high-speed serial SPI interface and its unlimited write cycle endurance is ideal for use cases that require frequent or fast write operations, such as data logging related to predictive maintenance of EV chargers.

Infineon's ModusToolbox™ is a collection of easy-to-use software and tools that enable rapid development of Infineon microcontrollers and AIROC™ Wi-Fi and Bluetooth® devices. It provides both development tools and run-time software for a flexible and comprehensive development experience. The ModusToolbox™ tools package includes desktop programs that enable the creation of new embedded applications, managing software components, configuring device peripherals and middleware, and embedded development tools for compiling, programming, and debugging. The ModusToolbox™ run-time software includes an extensive collection of GitHub-hosted repositories comprised of code examples, board support packages, middleware, and application support.

The continuous transfer of information essential for overseeing EV charging stations, both nearby and at a distance, underscores the integral role of connectivity in this comprehensive solution. In scenarios that encompass over-the-air firmware updates, live monitoring, secure data exchange, and integration with intelligent home systems, the AIROC™ CYW4373E System on a Chip (SoC) is engineered to bolster EV charging services. This SoC is equipped with dual-band Wi-Fi 5 (802.11ac) that operates on 2.4/5 GHz frequencies, boasts an enhanced range, delivers top-tier RF output, and is operable within a vast temperature window spanning from -40 to +85 degrees Celsius.

For faster development, pre-certified Wi-Fi 5 modules based on the AIROC™ CYW4373 SoC include Murata’s Type 2AE (CYW4373E).

AIROC™ CYW20829 is a high-performance, ultra-low-power and secured MCU + Bluetooth® LE platform. It combines a high-performance microcontroller with Bluetooth® LE (5.4) connectivity, high-performance analog-to-digital conversion audio input, I2S/PCM, CAN, LIN for automotive use cases and other standard communication and timing peripherals. The CYW20829 in an EV charger, with its highly interoperable BLE stack, enhances the functionality and user experience by enabling remote monitoring and management of the charging process, delivering software updates, enabling contact-less user authentication, payment processing, and access control.

Adding to the security aspects of EV charging, the OPTIGA™ TPM SLB 9673 FW26.xx emerges as the newest member of the OPTIGA™ TPM product line, designed for connected devices necessitating advanced security measures. This standardized and immediately deployable security solution is equipped with an I2C interface and lays a solid groundwork for the verification and authentication of network infrastructure devices, while also safeguarding data integrity and privacy. The OPTIGA™ TPM for EV Charging provides robust security features that act to fortify the entire charging infrastructure against potential threats and vulnerabilities, ensuring that the process of authentication and data protection is both reliable and effective.
