A42MX09-2PL84

FPGAs are a type of integrated circuit used to realize digital logic in computing applications. They are particularly suited for embedded systems, where reconfigurability is often of paramount importance. The A42MX09-2PL84 is a type of FPGA from Atmel Corporation. It is a field-programmable gate array (FPGA) with a wide range of applications.

The A42MX09-2PL84 is a highly reconfigurable device with four 64-bit wide memory ports, four general-purpose peripherals, two input/output (I/O) pins, four simultaneous clock inputs, four external clock sources and up to one user-defined clock input. Its 256 logic cells, coupled with its ability to support up to 16 million logic gates, make it an ideal choice for applications requiring tight resource constraints.

In terms of applications, the A42MX09-2PL84 is well-suited to a variety of different tasks, including system-on-chip (SoC) design, logic design, and the emulation of digital systems. It is also a popular choice for digital signal processing (DSP) and digital control applications, as well as memory mapping, device emulation and debugging.

In terms of working principle, its internal logic structure is composed of a cluster of four 16-bit ALUs, two 64-bitRAMs, four 64-bit wide memory ports, and two programmable I/O pins. The ALUs are connected to the 64-bit RAMs, allowing for data manipulation and support for up to 16 million logic gates. The A42MX09-2PL84 is designed for use with the Atmel AT40K microcontroller family, providing a simple method of controlling the FPGA through the I/O pins.

Overall, the A42MX09-2PL84 is a powerful FPGA, offering high performance and flexible programming options in a cost effective package. Its wide range of applications and robust design make it an attractive choice for embedded systems designers seeking superior performance in a small form factor.
