Overview

Description

RL78/I1B microcontrollers adapt various electricity meter metrologies for different regulations by country and realize the efficient power measurement by the combination of low active current 96uA/MHz, standby current 0.66uA (Halt mode with 32kHz oscillator and RTC backup on), 24-bit ΔΣA/D converter, phase adjustment circuits and high pass filter. CPU clock frequency can be minimized taking advantage of the efficient power measurement features, which includes the low power ΔΣ A/D converter 0.53mA/ch. RL78/I1B microcontrollers have +/- 1% high-accuracy high-speed on-chip oscillator with +/-0.05% frequency correction function and keep the system robust by the benefit of the accurate on-chip oscillator even when the external oscillator is stopped.

Features

  • CPU: RL78 core, Max. 24MHz
  • Voltage: 1.9V to 5.5V
  • Package: 80 to 100-pin QFP
  • Memory: SRAM Max. 8KB, Program Flash Max. 128KB
