Introduction

The A42MX24-1PQ208I is a member of Actel\'s A42MX24 family of FPGAs. It\'s a high-performance and low-cost solution for embedded applications that require a moderate amount of logic. It provides up to 24Kbits of embedded SRAM dedicated to data and instruction storage, with an additional 128Kbits of distributed RAM/ROM for online configuration of embedded logic. This FPGA is available in two different packages: a 28-pin TQFP with a 484-ball BGA, and a 144-ball TQFP with a 144-pin BGA.

Application Field

The A42MX24-1PQ208I FPGAs offer superior performance and low cost while providing high reliability and excellent noise immunity, making them ideal for high-performance military and aerospace applications. They are widely used in embedded system designs and many embedded application fields such as motor control, high-speed motor module control, navigation, servo motor control, and industrial robot control.

They are also widely used in industrial and automotive applications such as factory automation systems, vehicle control systems, and factory visualization.

Working Principle

The A42MX24-1PQ208I FPGAs employ a hierarchical two-dimensional reconfiguration approach, which is based on the principle of partial reconfiguration. During the writing process, the selected portion of the device is suspended, enabling independent configuration of the designated area and concurrent program execution to data memory and logic functions in other regions. This design methodology utilizes a combination of fast SRAM/logic blocks, distributed ROM/RAM, and an embedded controller, which provides an effective balance of performance, cost, and time-to-market.

At the same time, this FPGA also employs an "ultimate low power" approach to reduce power consumption. The combination of ultra-low power modes and fine-grain shut-off control allows designers to achieve extreme low power dissipation levels. This ensures that an entire system can be easily implemented in a low-power, low-cost package.
