Overview
Achieving raw performance is no longer the
number one issue—it’s now “performance within
an energy budget.” Freescale understands this
challenge and offers a wide portfolio of S08
devices that help you reach target performance
levels while minimizing low power in your
design. 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, I
2
C 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
