Overview
Description
The RX113 Group microcontrollers have built-in communications functions such as USB and IrDA, a capacitive touch sensor (CTSU), a segment LCD, and a serial sound interface (SSI). They offer a single-chip solution for industrial and measuring devices that have low current supply capabilities, or for user interfaces for system control in home appliances, healthcare devices, and so on.
