Ticket Vending Machine

This reference design by Renesas is used for a ticket machine used in train stations and utilizes a TFT display for customers to purchase tickets. The reference design also features voice guidance via a speaker and can detect abnormalities inside the device with a temperature sensor. When updating the firmware of this application, this can be rewritten using a USB. Two RX65N 32-bit microcontrollers (MCUs) are used to recognize bills and coins.

System Benefits

• The RX72N 32-bit MCU is a high-performance product that operates at 240 MHz with a line up max of 224 pins, so you can use many functions without duplicating pins
• Performs TFT display processing that requires high performance, and high-quality audio through the synchronous serial interface (SSI) with one chip
• The HS3004 sensor measures the temperature inside the equipment and helps detect abnormalities
• RX flagship MCU with highest performance
• RXv3 core and high-performance operation at 240 MHz
• 120 MHz RXv2 core MCU
• Large ROM/RAM, enhanced security, connectivity and HMI
• Wide V_IN dual-standard Buck regulator with 3 A / 3 A continuous output current
• Efficient asynchronous Buck regulator
• Good for network and communication equipment, industrial control, point-of-load regulators
• Relative humidity and temperature sensor
• High-accuracy humidity and temperature sensing for environmental monitoring
