RX111

The RX111 Group has a comprehensive small-capacity ROM/low pin count lineup and built-in USB 2.0

 

The RX111 Group has a comprehensive small-capacity ROM/low pin count lineup. With USB 2.0 for Battery Charging (BC 2.0), low consumption current, and fast wakeup from standby, these microcontrollers are suitable  for use in computer peripherals, and healthcare and wearable devices. With their three-phase motor control timers, they are also suitable for motor control applications in home appliances and industrial equipment.

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.
