RX111 Group User’s Manual: Hardware

Overview of the RX111Group

The RX100 Series is the low pin count, low power series of the RX Family. This product series is positioned at even lower pin counts, smaller capacity flash, and lower price than the RX200 Series.
■ Realize both low end   high performance
  • 32bit product lineup with small-pin count/small-size Flash
  • High performance, high functions & cost effectiveness (3.08CoreMark/MHz)
  • Fast wake-up (4.8μs) from standby mode to run mode
■ Shorten development TAT
  • Compatibility between RX200 & 600, scalability
  • Common development environment among RX series
■ Pursue lower power consumption
  • World’s lowest current performance ratio (14.9CoreMark/mA)
  • Low current consumption (0.1mA/MHz) in run mode
  • Low standby current (0.35μA) without power shutdown

The main specifications of the RX111 microcontrollers are as follows.
