MCUs for entry-level automotive applications

20 February 2008 DSP, Micros & Memory

Freescale is providing embedded developers with a cost-effective 8-bit microcontroller (MCU) to help expand their automotive design possibilities.

As automotive applications continue to become smaller, more sophisticated and more cost-sensitive, designers require a broader range of affordable, feature-rich MCU options. To address this need, Freescale has introduced the S08QD MCU family - the company's first 8-bit small outline integrated circuit (SOIC) devices designed to reduce board space, system cost and power consumption for entry-level automotive applications.

The S08QD family provides high flexibility and functionality, and its 5 V support within a compact, 8-pin package make it suitable for cost-sensitive applications that require higher voltages. In-vehicle applications include HVAC dampeners, mirror dimming, actuators, sensors/meters, watchdogs, pushbutton control and other entry-level, general-purpose automotive applications.

The S08QD MCU family integrates a four-channel, 10-bit analog-to-digital controller designed for high resolution, fast conversion and featuring an automatic compare function. The internal clock source (ICS) module contains a frequency-locked loop (FLL) controlled by an internal or external reference. The S08QD family is pin-compatible with the SG and EL MCU families, so that the shared peripherals and a common set of development tools help make it possible for engineers to leverage their design investments.
