RL78/D1A microcontrollers have a built-in sound generator which can set a volume level and tone frequency of 100 Hz to 6 kHz and has an automatic volume decrement function, up to four channels of stepper motor controller/driver which can set an 8-bit precision (pseudo 9-bit precision using a 1-bit addition function) pulse width (PWM output), and an LCD controller/driver which supports up to 216 segments. The 128-pin version has a built-in LCD bus interface and two channels of CAN, and expanded flash memory/RAM up to a maximum of 512 KB/24 KB, making these microcontrollers ideal for low-end instrument cluster.
