AC Charging Pile Solution Based on MYIR’s MYC-YA15XC-T System-On-Module

Electric vehicles (EVs) have always been regarded as the next generation of automobiles. With the rise of EVs, the demand for charging piles is also set to experience large-scale industry development.. The European standard AC charging pile needs to integrate an AC charging interface, a human-computer interaction interface, electrical safety design and protection. It cooperates with the vehicle-mounted charger of electric vehicles to provide multiple charging methods such as card swiping and mobile payment, requiring a high degree of integration of human-machine interaction, control, measurement, and safety protection units.

The MYC-YA15XC-T System-On-Module (SOM) from MYIR is built on the STM32MP1 processor, utilizing a heterogeneous architecture that incorporates either a single-core or dual-core configuration of Cortex-A7 and Cortex-M4 processors. This design enhances the module's capability to support multiple applications and flexible usage scenarios, providing customers with a cost-effective development solution. The module is equipped with a wide range of interface resources, facilitating easy application expansion. Additionally, it offers an optimized combination of performance and cost advantages.

The MYC-YA15XC-T SoM features a Castellated-Hole package and is equipped with the STM32MP151 processor, boasting a clock frequency of up to 650 MHz. It offers a rich array of peripheral interfaces, including USB 2.0, Ethernet, UART, CAN, LCD, DCMI, and ADC, allowing for flexible customization by customers. MYIR's MYC-YA15XC-T SoM is characterized by its low power consumption and long-distance data processing capabilities. Additionally, MYIR provides the MYC-YA15XC-T development board along with comprehensive development documentation to assist customers in successfully implementing their projects.
