8-bit General Purpose GT MCUs

The MC9S08GT family are cost-effective, high-performance S08 general purpose 8-bit microcontrollers. All MCUs in the family use the enhanced S08 core and are available with a variety of modules, memory sizes, memory types and package types.

Additionally, the MC9S08GT16A and MC9S08GT8A series of microcontrollers further extend the GT family to smaller memory sizes, while maintaining higher end functionality often associated with more expensive parts. MC9S08GT16A doubles the RAM of its predecessor. An additional option is offered for those customers requiring an 8 KB flash part.

Timer with Five Programmable Channels

1 x 3 channel, 1 x 2 channel, 16-bit timer systems
Each channel programmable for
- Input capture, output compare or buffered pulse-width modulator (PWM)
- PWM can be edge- or center-aligned
16-bit free-running or up/down (CPWM) count operation
Flexible, programmable timer system

System Protection

Selectable low-voltage detect/reset at nominal 1.8V
Low-battery warning at nominal 2.4V or 2.1V
COP watchdog timer
Loss of clock detect (LOCD) (with option to disable for lower power consumption)

Up to 39 Input/Output (I/O) Lines

Programmable pull-ups
High-current drivers
Eight keyboard interrupts
Controlled rise/fall times minimize noise
