Overview
Actel refers to a series of programmable logic devices (PLDs) developed by Microsemi (now part of Microchip Technology). These devices are based on non-volatile flash technology, which allows them to retain programming even when power is removed. Actel PLDs are widely used in industries requiring high reliability, such as aerospace, automotive, and industrial automation. Unlike volatile FPGAs, Actel devices do not require external configuration memory, making them more secure and easier to deploy in critical applications. Their low power consumption and resistance to radiation also make them suitable for space and military applications.
Structure and Working Principle
Actel PLDs consist of an array of logic blocks interconnected via a programmable routing matrix. The logic blocks contain flip-flops, look-up tables (LUTs), and other digital components that can be configured to perform specific functions. The flash-based configuration memory ensures that the device retains its programming without external intervention. Programming an Actel device typically involves using proprietary software tools to define the desired logic functions and generate a configuration file. This file is then loaded into the device, where it remains until reprogrammed. The non-volatile nature of the flash memory makes Actel devices resistant to configuration upsets caused by power fluctuations or radiation.
Key Features
Actel PLDs are known for their high reliability, low power consumption, and secure operation. The flash-based technology eliminates the need for external configuration memory, reducing system complexity and improving security. Additionally, Actel devices are designed to withstand harsh environmental conditions, including extreme temperatures and radiation. Another notable feature is their low static power consumption, which makes them ideal for battery-powered and energy-efficient applications. The devices also support advanced security features, such as encryption and tamper detection, to protect intellectual property and prevent unauthorized access.
Application Areas
Actel PLDs are widely used in industries that demand high reliability and security. In aerospace, they are employed in avionics, satellite systems, and flight control systems due to their radiation tolerance and non-volatile memory. Automotive applications include engine control units, safety systems, and infotainment systems. In industrial automation, Actel devices are used for programmable logic controllers (PLCs), motor control, and sensor interfaces. Their low power consumption and small form factor also make them suitable for portable medical devices, military communications, and IoT applications.
Maintenance and Precautions
To ensure the longevity and performance of Actel PLDs, it is important to handle them with care. Avoid exposing the devices to electrostatic discharge (ESD) by using proper grounding techniques during installation and handling. Follow the manufacturer's guidelines for programming and reconfiguration to prevent damage. Storage conditions should be dry and within the specified temperature range to avoid moisture absorption or thermal stress. Regularly update the programming software and firmware to leverage the latest features and security enhancements provided by the manufacturer.
B2B Procurement Guide
When procuring Actel PLDs, consider the specific requirements of your application, such as logic density, power consumption, and environmental conditions. Verify the availability of development tools and support resources, as these can significantly impact the design and implementation process. For bulk purchases, negotiate pricing and lead times with authorized distributors or directly with Microchip Technology. Ensure that the devices meet industry standards and certifications relevant to your application, such as automotive (AEC-Q100) or aerospace (MIL-STD-883).
