GPIO Controller IP

Design IP

Overview

SmartDV’s General Purpose Input/Output (GPIO) Controller IP is a silicon-proven solution designed to manage a wide range of digital I/O operations in embedded systems, SoCs, and microcontroller-based designs. It enables efficient interfacing with external devices and peripherals, supporting programmable direction control, interrupt generation, and configurable output drive strength.

Designed for flexibility, the IP core is highly configurable to meet specific design requirements, supporting both ASIC and FPGA implementations while optimizing for area, power, and performance. Its robust architecture and ease of integration make it ideal for consumer electronics, automotive, industrial, and IoT applications.

Benefits

Flexible I/O Configuration – Supports programmable GPIO pins configurable from 1 to 32 bits, with each pin dynamically programmable as input or output
Advanced Control Capabilities – Enables per-pin dynamic control of drive strength, pull-up/pull-down enable, and trigger mode (level or edge)
Customizable Trigger Options – Supports dynamic configuration of active-high or active-low level triggers for precise signal response
Robust Interrupt Management – Provides optional interrupt generation with configurable rising or falling edge detection for event-driven applications
Seamless SoC Integration – Compliant with standard GPIO specifications and compatible with common SoC bus interfaces including APB, AHB, and AXI
Efficient and Scalable Design – Parameterizable architecture allowing easy scaling to match specific system requirements

Compliance and Compatibility

Compliant with standard GPIO interface specifications
Compatible with all major EDA synthesis, simulation, and linting flows
