The MC9S08QD4/2 provides design flexibility and
integrated functionality for small appliances and DC
fans. The QD includes up to 5.5V supply voltage,
a 10-bit analog to-digital converter (ADC) and two
timers for improved motor control. The MC9S08QD
extends the advantages of the low-end S08 core
as a low-pin-count, small-package 8-bit MCU. With
pin and tool compatibility with MC9RS08KA and
MC9S08QG8, the QD allows designers to move up
and down the performance spectrum quickly
and easily.
