D6840

D6840 IP Core — Programmable Timer Module for High-Precision Embedded Applications

Versatile 16-Bit Timer Module for D68xx Processors and Beyond

The D6840 IP Core from DCD-SEMI is a programmable timer module compatible with the industry-standard 6840 timer. Designed for embedded systems, the D6840 is ideal for peripheral devices in D68xx processor architectures, or as a standalone IP Core in systems requiring precise timing control.

This timer module features three independent 16-bit timers, each with individual control registers and common status registers, offering flexible timing capabilities for a wide range of applications.

Advanced Timer Functionality

The D6840 supports:

• Square Wave Generation: Produce continuous or single-shot waveforms with adjustable duty cycles

• Frequency and Pulse Width Measurement: Accurate timing and pulse analysis for control and monitoring applications

• Timer Comparison: Compare timer values for advanced event handling

• Interrupt Support: Generate CPU interrupts for precise system control and synchronization

Flexible and Technology-Independent Design

As with all DCD-SEMI IP Cores, the D6840 is technology-independent, enabling seamless implementation across FPGA, ASIC, and SoC designs. Its modular architecture allows easy integration into both legacy and modern embedded systems requiring reliable timing, waveform generation, and measurement capabilities.
