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 pull-ups on ports when used as input; internal pull-up on reset and interrupt request (IRQ) pin
- 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
- 8-pin plastic dual-inline package (PDIP) and 8-pin narrow body small outline integrate circuit (SOIC) packages
- Internal pull-up on reset and IRQ pin
Integrated Analog Peripherals
- 4-ch., 10-bit ADC with automatic compare function
- ADC channel connected to on-chip temperature sensor
- Automatic compare function, software programmable for greater-than, equal-to or less-than conditions
- Asynchronous clock source
- Temperature sensor
- Internal bandgap reference channel
- Hardware triggerable using the real-time interrupt counter
- Low-power and high-speed options
- Can be used for single slope APC and resistance-capacitance time
- Easy interface to analog inputs/sensors
- Used to set conversion complete and generate interrupt only when result matches condition
Flexible Clock Options
- Internal clock source module containing a frequency-locked loop controlled by internal reference
Two Timer Modules
- Programmable 16-bit timer/PWM (TPM) module
- 2-ch. TPM; each channel can be used for input capture, output compare, buffered edge-aligned pulse width modulation (PWM) or buffered center-aligned PWM
- 1 x 2-ch., 16-bit timer
- 1 x 1-ch., 16-bit timer
System Protection
- Watchdog computer operating properly reset with option to run from dedicated 1 kHz internal clock source or bus clock
