Overview

Achieving raw performance is no longer the

number one issueits 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 yourdesign. 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
