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 QB family demonstrates extreme
energy efficiency for ultra-long operating life
in battery-powered applications.
As a subset of QE family, the QB8 16-pin TSSOP
and 28-pin SOIC are pin compatible with the
QE8 device. The S08QB8 (QB8) microcontroller
offers low-power features such as two ultra-
low-power stop modes, new low-power run and
wait modes, 6 μs wake-up time, ultra-low-power
external oscillator and clock gating registers to
disable clocks to unused peripherals.
The QB8 offers up to 8 KB of flash memory
and an 8-channel, 12-bit resolution analog-
to-digital converter (ADC). The S08QB8 can
be powered down to 1.8V and still able to
operate at maximum 20 MHz CPU speed. QB8
consists of a 8-bit modulo timer, a 16-bit timer/
pulse width modulator, UART, real time counter,
analog comparator, 8-channel keyboard interrupt
module—perfect for cost-effective, battery
sensitive, portable, low-power applications.
