Pins on the HCS12 configured as digital inputs are guaranteed to report a logical high if the input voltage is greater than 0. Pre-coded C-language routines make it easy to access these features.

Freescale HCS12 9S12 Datasheets

Device Overview and Block Diagram. Index to all documents, tutorials, and user guides. At NI, we produce high-performance hardware and are committed to helping you maintain that performance for years to come.

Our three- or five-year service programs for hardware and systems provide the dataxheet you need while ensuring lowest total cost of ownership over the life of your system:. You can use them to directly drive LEDs, relays, transistors, opto-isolators or other digital logic devices. The specified maximum instantaneous current is 25 mA into or out of any one pin at a time.

Input voltages between 1. At greater output currents the resistance increases gradually, but the 40 ohm approximation holds good up through the 25 datasehet maximum.

Overview of the MC9S12A microcontroller. Pin currents must be limited using external resistors. Negative going noise on the input voltage will not cause a false transition back to a logic 0 unless it is greater than 0. The detailed specifications provide the timing information you may sometimes need when writing c language application programs.

Input pin logic levels and threshold voltages.

The consequence of this hysteresis eatasheet that the threshold between a logic high and a logic low depends on whether the input voltage is rising or falling. View Pricing and Purchasing Information.

Mosaic Industries web site. Beware however that it is not always clear which specifications are shared by the two versions, and which apply only to the X-version of the processor. They consist of internal diodes that conduct current from the input pin to the supply or ground rails in the event that the input pin voltage exceeds the supply range.

For some applications, particularly when driving inductive loads such as relays, you may need to provide Schottky diode clamps between the pin and V DD and between the pin and ground. Prevent excessive voltage levels at the pin; and.

We calculate it as. To access NI technical support services for your hardware, visit ni. You may either source current to the LED, or sink current from it, as shown in the following circuit. NI equips engineers and scientists with systems that accelerate datassheet, innovation, and discovery. Service Programs for Hardware At NI, we produce high-performance hardware ucs12 are committed to helping you maintain that performance for years to come. The maximum current you should ever sink with the pin is 25 ma.
