The QE family demonstrates extreme energy efficiency for ultra-long operating life in battery-powered applications. The S08QE8 (QE8) microcontroller offers low-power features such as two ultra-low-power stop modes, new low-power run and wait modes, 6 usec wake-up time, ultra-low-power external oscillator and clock gating registers to disable clocks to unused peripherals. The QE8 32-pin-LQFP device is pin compatible with the QE128 S08 and ColdFire V1 devices.
