H8 Super Low Power



H8 Super Low Power

Renesas's H8 Super Low Power Microcomputers provide low power consumption, low voltage operation and low noise microcomputers for all battery powered products or low power applications. Super Low Power Microcomputer have three CPU options ranging from low cost 8-bit (H8/300L) microcomputers to powerful 16-bit devices (H8/300H and H8S). Super Low Power Microcomputer offer various on-chip peripheral functions with a wide range of on-chip flash memory options for ease of product development.


  • Multiple techniques minimize power consumption and extend battery life
    • Low-power CMOS technology
    • Low-voltage operation (1.8V)
    • Power-down modes
  • Shorter oscillation stabilization time lets application wake up faster from standby mode, conserving power
  • High-current port for driving LEDs directly
  • 16-bit asynchronous counter operates even when device is in standby mode
  • Code-and peripheral-function compatibility with other Renesas microcontroller families
  • Low-cost development tools using on-chip debug
