D6840

The D6840 is a programmable timer module compatible with the 6840 industry standard. It was designed to be used in peripheral devices for D68xx processors. Moreover, our proprietary IP Core works perfectly as a separate module in applications where the 6840 timer features are useful. The D6840 has three separate 16-bit timers with individual control and common status registers. The timers may be used for square wave generation with duty cycle regulation. The signal may then be generated as a continuous wave or single-shot mode.
But this is not all – our unique module can be used for frequency or pulse width measurement and comparison. The D6840 has an interrupt which is used by the CPU in a controlling module. Like all of our solutions, the D6840 is a technology-independent design that can be implemented in a variety of process technologies.
