QE MCU addition saves power
09 September 2008
The QE32 Flexis enhances portable performance, extends battery life and improves energy efficiency.
Freescale has added to its QE 8bit MCU family with the QE32 Flexis MCU (MC9S08QE32) which has a large peripheral set with multiple time-pulse modulation, general purpose I/O and serial communications interface channels. The level of peripheral integration reduces component count and system cost in the end design, typically power-sensitive wireless and battery-operated applications such as toys, smoke detectors, utility meters and heating and ventilation air conditioning systems.
The MCU is designed to operate from a low-power, 32kHz oscillator, consuming less than 7.3mA. There are battery-saving features such as two ultra-low power stop modes, low power run and wait modes, six usecs wake-up time from stop mode and clock gating registers to disable clocks or unused peripherals.
It an HCS08 core, operating at up to 50.33MHz and 25.165MHz bus frequency. There is up to 32k flash and up to 2k RAM. The MCU operates form 1.8V to 3.6V and at -40 C to 85 C.
Package options are the 48QFN, 44LQFP, 32LQFP and 28SOIC.
The MCU is pin and software-compatible with other devices in the Flexis QE family and together with the company’s Controller Continuum, is described as providing a software-compatible roadmap from 8bit to 32bit architectures.
