Smart vending machines have increased in popularity, with the trend to be cashless. The basic functions include an Human Machine Interface (HMI) with payment and secure monitoring in the cloud. This solution includes the Renesas Synergy S5D9 microcontroller (MCU) which has on-chip hardware security, an LCD controller, and qualified SSP for quickly connecting to the cloud. A Narrowband Internet of Things (NB-IoT) modem enables direct connection to cloud. The HS300x sensor provides high accuracy and excellent stability for measuring humidity and temperature. And, with power support from the ISL8117 DC/DC controller, ISL6294 battery charger and an ISL80103 LDO, the system is complete.
This solution can support differential cable Ethernet and cable-less WLAN connections, such as Wi-Fi and NB-IoT. The hardware encryption and software protocol, Transport Layer Security (TLS), ensures a secure cloud connection. The capacitive touch and larger color TFT-LCD support an optimized HMI experience for the user.
