The QE family demonstrates extreme energy efficiency for ultra-long operating life in battery-powered applications. Further expanding the QE family portfolio, the QE32 provides great flexibility for customers to balance performance and power consumption. The QE32 offers low-power features such as two ultra-low-power stop modes, 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 QE32 offers up to 32 KB of flash memory, a 10-channel, 12-bit resolution analog-to-digital converter (ADC), abundant peripherals such as three timers/PWM, two SCI, SPI, I2C and two analog comparators. QE32 can operate at 1.8V voltage supply and run up to 50.33 MHz core frequency. To test your application with the QE family, take the Battery Calculator challenge, available at www.freescale.com/lowpower. 8-bit Fact Sheet Ultra-Low-Power Microcontrollers MC9S08QE32/16 Taking the lead in low power Features Benefits Power-Saving Features • Twoultra-low-powerstopmodes,oneofwhich allows limited use of peripherals • Allowscontinuedapplicationsamplinginareduced power state which extends battery life • Allows use of all chip peripherals in a low-power state • Enablesfasterexecutionoutofstopmodes • Low-powerrunandwaitmodes • 6µstypicalwakeuptimefromstopmode • InternalclockSource(ICS)—modulecontaininga frequency locked-loop (FLL) controlled by internal or external reference • Provideschoiceoffrequencieson-the-fly.
