MCU 8-bit HCS08 CISC 2KB Flash 3.3V/5V 8-Pin PDIP Rail

The cost-effective MC9S08QD family is the lowest-end member in the S08 8-bit  microcontroller architecture. MC9S08QD products are a perfect fit for a wide variety of low-end 8-bit MCUs for both automotive and industrial applications. To order automotive specific devices select part numbers that start with "S" in the Buy/Parametrics tab.

8-bit HCS08 Central Processor Unit (CPU)

• Up to 8 MHz S08 CPU for 125 ns minimum instruction time
• HC08 instruction set with added background instruction
• Support for up to 32 interrupt/reset sources
• Supply voltage range of 2.7–5.5V

Integrated Third-Generation Flash Memory and RAM

• Embedded flash that is in-application reprogrammable over the full operating voltage and temperature range with a single power supply

General Purpose Input/Output (GPIO) Lines

• Outputs 10 mA each; 100 mA max for package
• Four general-purpose input output (GPIO)
• One input-only and one output-only line

• Software selectable slew rate control and drive strength on ports when used as output
• 4-pin keyboard interrupt module with software selectable polarity on edge or edge/ level modes
• 1-ch. timer/pulse-width modulator; each channel can be used for input capture, output compare, buffered edge-aligned PWM or buffered center-aligned PWM
• Software-selectable pull-ups on ports when used as input; internal pull-up
• Software-selectable slew rate control and drive strength on ports when used as output
• Single-wire background debug interface
