M390 Group
The 1.8-V low-power mode of the M390 Group makes it ideal for battery-operated applications. The on-chip high-speed,
high-accuracy oscillator helps reduce product costs. The M390 Group are available in standard and small packages.

Low-Power MCUs
Audiovisual systems must be able to receive Consumer Electronics Control (CEC) commands and remote control signals even when they are off.
While the predecessor microcontrollers, the TLCS-900/L1 and TLCS-870/C Series, need to keep these functions in normal operating mode even
when off, the M390 Group of microcontrollers can do them in low-power mode at 32.768 kHz, significantly reducing standby power consumption.
