Overview

RL78/G1A microcontrollers balance the industry's lowest level of consumption current (CPU: 66 μA/MHz, standby (STOP): 230 nA) and a high performance of43.2 DMIPS (32 MHz). A built-in high-resolution 12-bit A/D converter, on-chip oscillator, data flash, and safety features (function that detects illegal operation of hardware) enable support for the household appliance safety standard (IEC/UL 60730). With an lineup of 25 to 64-pin LGA/BGA and other small packages, these microcontrollers are perfect for consumer and industrial sensor applications.

  3. RL78 RTC constant-period interrupt question

    I notice in applilet3, the RTC module setting. for constant-period interrupt, there is only a few option. 0.5s, 1s, 1min, 1hour, etc. I want to set the constant-period 10 sec. How do I do then?any idea? I am using IAR IDE with applilet. the MCU is ...

  3. Tell me the points to be aware of when using the RL78 Code Generator with the WDT.

    In the RL78 Code Generator, the Watchdog Timer (WDT) is set to 'Enabled' by default, as shown in the diagram below. To avoid unintended resets by the WDT, please either select 'Disabled' for the 'Watchdog Timer Operation Setting' or add a program to clear the Watchdog Timer counter.
