Freescale is pleased to announce the launch of the extremely cost effective QD family-the 9S08QD4 and 9S08QD2 devices - the lowest end members in the 8-bit S08 microcontroller family and an expansion to the popular Q Family.

With a four channel 10-bit ADC, two timers, up to 32 interrupt sources, 4K Flash (QD4) or 2K Flash (QD2) and 5V operational voltage, the 9S08QD family is a perfect fit for a wide variety of small appliances such as DC fan applications (PCs and HVAC systems), microwave ovens and ignition control systems.

The 9S08QD devices are pin and software compatible with RS08KA2 and S08QG8 8-bit microcontrollers, offering greater design flexibility within Freescale’s low end portfolio. These device are available in 8-pin SOIC and plastic DIP packages in both industrial (-40º to + 85ºC) and extended temperature (- 40º to + 105ºC) ranges.

 

Evaluation Tools
DEMO9S08QD4 is a demonstration board for the MC9S08QD4 8-bit microcontroller. Application development is quick and easy with the integrated programmer/debugger tools (USB-BDM) and software (CodeWarrior™) included. A 32-pin connector allows connecting the DEMO9S08QD4 board to an expanded evaluation environment.

 

FEATURES 8-bit HCS08 CPU Flexible clock options System protection Development support Integrated third generation Flash memory and RAM General purpose Input/Output (I/O) lines Integrated analog peripherals Two timer modules 4KB Flash 256 bytes RAM Flash read/program/erase over full operating voltage and temperature 4 channel, 10-bit ADC Dual 16-bit on-chip timers Internal clock oscillator with 2 percent deviation over temperature and voltage Single-wire background debug interface On-chip in-circuit emulation with real-time bus capture 8-pin PDIP and 8-pin narrow body SOIC packaging The 9S08QD2 was introduced in January 2007

APPLICATIONS Digital capacitive discharge ignition systems for motorbikes and motorcycles Portable air coolers Small appliances Large appliances Camera zoom control Chargers Treadmills Vacuum cleaners

 

The 8-bit MC9S08QD4 (QD4) microcontroller expands the low end capabilities of Freescale’s Controller Continuum. It offers enhanced functionality and flexibility while maintaining pin compatibility with the ultra low end KA2 family based on RS08 core technology and the highly integrated QG8 family of S08 controllers.

The QD4 incorporates a high performance 4 channel, 10-bit analog-to-digital converter (ADC), which makes it an ideal solution for DC cooling fans in computer applications, low power supplies and telecommunications equipment.

The QD4 is the S08 controller at the lowest end of the Freescale portfolio, but still offers more flash memory and RAM than other 8-bit microcontrollers in the same price range. It boasts two 16-bit on-chip timers, one 2 channel timer and another 1 channel timer. Each channel can be used for input capture, output compare; buffered edge aligned pulse width modulator (PWM) or buffered center-aligned PWM.
