Suitable single-chip solution for bidirectional human-machine interface (HMI) and interfacing with various peripheral devices


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.

Hardware Design Support

Title Description
IBIS/BSDL IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board. BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
Resonator Information Please search for your resonator on its manufacturer's site linked below. If you require optimal oscillation circuit constants for your particular system, please ask the manufacturer of the oscillator.
