Description
RL78/G14 microcontrollers balance the industry"s lowest level of consumption current (CPU: 66 µA/MHz, standby (STOP): 240 nA) and a high calculation performance of 44 DMIPS (32 MHz). The built-in high-function timer supports three-phase motor control using three-phase complementary PWM output. They have an on-chip oscillator, data flash, A/D and D/A converters, comparator, and more. Built-in safety features (function that detects illegal operation of hardware) enable support for the household appliance safety standard (IEC/UL 60730). With a broad 30 to 100-pin lineup and up to 512 KB on-chip flash memory, these microcontrollers can be used in a wide variety of applications such as motor control and consumer and industrial equipment.
