The Renesas MicroClock family of ultra-low-power, miniature programmable clock generators help maximize battery life and decrease the solution size of wearables, hearables, smart devices, and embedded systems. Each device includes three outputs, selectable frequency options from 1MHz to 100MHz and configurable spread spectrum clocking to reduce EMI. 

The MicroClock programmable clock generators are all equipped with innovative features and low-power DCO to support battery-powered device requirements. Each device is OTP programmable to allow for up to three unique frequency outputs

Features and Benefits

  • Ultra-low power consumption 
  • Small packages reduce board space and lower BOM costs
  • Proactive Power Saving (PPS) actively switches modes according to downstream clocked component status
  • Dedicated OE pin for each output minimizes power consumption based on performance requirements 
  • Dynamic Frequency Control (DFC) allows fast changes between pre-selected frequencies 
  • Spread Spectrum technology attenuates system EMI 
  • Multiple output swing options for SOC with low swing clock requirement 

Comprehensive Development Tools

  • Simplify design process and speed time to market.
  • Development kit with USB programming board, Timing Commander™ GUI and blank socket devices enable rapid programming
  • Tiny evaluation board allows easy verification on an existing system board
