The M380 Group consists of high-performance microcontrollers that provide multi-purpose timers capable of controlling power

devices used in home appliances, thereby enabling motor and induction heating (IH) control. Since they operate with a single

5-V supply, new designs can be created without replacing 5-V peripheral ICs. Additionally, a wide variety of on-chip timers and

serial interfaces makes the M380 suitable for a broad range of applications, including housing and industrial equipment. The

oscillation frequency detection (OFD) circuit allows the M380 to detect abnormal oscillation at the hardware level.
