CP82C54-10 – INTERSIL

Overview

The Renesas Electronics (formerly Intersil) CP82C54-10 is a high-performance, 6-channel programmable interval timer designed to provide precise timing and counting functions within digital systems. Its core strength lies in its ability to generate complex timing waveforms and generate interrupts with minimal CPU intervention, a critical factor in real-time control applications. A key design consideration when integrating this device is managing the trade-off between its maximum operating frequency (10 MHz) and its propagation delay (100 ns); pushing the frequency too close to the limit can compromise timing accuracy in high-speed data acquisition or control loops, necessitating careful clock domain analysis.
