This reference design is used for a ticket machine used in train stations and utilizes a thin-film transistor (TFT) display for customers to purchase tickets. The reference design also features voice guidance via a speaker and is able to detect abnormalities inside the device with a temperature sensor. When updating the firmware of this application, you can rewrite it 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 240MHz with a line up max of 224 pins, so you can use many functions without duplicating pins
  • Not only can you perform TFT display processing that requires high performance, you can also achieve 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
