8-bit MCU minimises power consumption
The new MC9S08QB from Freescale
Semiconductor is a new entry-level 3V,
8-bit MCU with integrated features
designed to minimise power
consumption.
The MCU offers six modes of operation,
including low-power wait and low-power run.
Extra energy savings are achieved via a
precision trimming internal clock source with a
32kHz low-power oscillator, and by a voltage
regulator with a fast 6µS wake-up time.
Freescale’s new low-power MCU features up
to 8 kbyte of Flash programme memory and up
to 512 bytes of SRAM. A range of serial
communications controllers are integrated
along with an eight-channel ADC, a separate
analogue comparator, one two-channel 16-bit
timer, one 8-bit modulo timer and an eight-channel
keyboard interrupt controller. The MCU
parts are available in TSSOP-16, QFN-24 and
SOIC-28 packages, supporting up to 24 GPIOs.
