Microprocessor / PID Controller IC

Product Specifications

Technical details and manufacturing context for Microprocessor / PID Controller IC

Definition

This product is a specialized integrated circuit (IC) designed for use in electronic control systems, particularly within the computer, electronic, and optical product manufacturing sector. It integrates a general-purpose microprocessor core with dedicated hardware and software for implementing PID (Proportional-Integral-Derivative) control algorithms. The IC serves as the computational heart of closed-loop feedback systems, continuously sampling process variables from sensors, comparing them to desired setpoints, and calculating error values. It then applies proportional, integral, and derivative corrections to generate output signals that drive actuators, thereby maintaining process variables at target levels with minimal deviation. The microprocessor core allows for flexible configuration and customization of control parameters, while the integrated PID logic ensures real-time, deterministic response. Typical applications include temperature control, motor speed regulation, pressure regulation, and flow control in industrial equipment. The IC is available in surface-mount packages (QFP-32 to QFP-100) and operates over an extended industrial temperature range of -40 to 85 °C. It supports a supply voltage of 3.3 to 5.5 V DC, with configurable PID update rates from 0.1 to 100 Hz. On-chip analog-to-digital converters (ADCs) offer 12 to 16-bit resolution, and digital-to-analog converters (DACs) provide 8 to 12-bit output resolution. Program memory (flash) ranges from 8 to 64 KB, and clock frequency from 8 to 80 MHz. The IC provides 8 to 64 I/O pins for interfacing with sensors and actuators. Power consumption is typically 0.5 to 5 W at full operation. It includes ESD protection rated at ±2 to ±4 kV (human body model) and operates in non-condensing humidity from 5% to 95% RH. These specifications are directory reference ranges; actual values must be confirmed with the manufacturer for specific models. The listed standards (e.g., IEC 60068-2-14 for temperature, IEC 61000-4-2 for ESD, IEC 60068-2-78 for humidity, JEDEC MS-026 for packaging) are procurement references and do not imply certification of any specific product. Always verify model-specific parameters and compliance with the legal manufacturer or supplier before selection.

Working Principle

The IC operates by sampling input signals from sensors via its analog-to-digital converters (ADCs). The microprocessor core executes the embedded PID algorithm, calculating the error between the measured process variable and the desired setpoint. It then computes proportional, integral, and derivative terms to generate a control output, which is converted to an analog signal via the digital-to-analog converter (DAC) and sent to actuators. This closed-loop process repeats at a configurable update rate (0.1–100 Hz), continuously minimizing error. The microprocessor allows parameter tuning and logic customization, while the integrated PID hardware ensures deterministic timing. The IC's performance depends on supply voltage, clock frequency, and environmental conditions within specified ranges.
