Freescale Semiconductor’s S08QD MCU family is 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 flexibility and functionality to help developers design a wider array of automotive applications. The S08QD’s high level of integration and 5V support within a compact, 8-pin package make it ideal for cost-sensitive applications that require higher voltages. In-vehicle applications include HVAC dampeners, mirror dimming, actuators, sensors/meters, watchdogs, push button control and other entry-level, general-purpose automotive applications.
The S08QD MCU family integrates a four-channel, 10-bit analog-to-digital controller (ADC) designed for higher resolution, faster conversion and an automatic compare function. The ADC enables the MCU to easily interface with analog inputs from devices such as sensors by converting the analog signal to a digital value. The automatic-compare functionality allows the MCU to compute values and perform comparisons to a preset threshold.
The S08QD also includes an internal clock source (ICS) module containing a frequency-locked loop (FLL) controlled by an internal or external reference. The internal reference clock can eliminate the cost of all external clock components, which helps reduce board space and enhances system reliability.
