A42MX24-PQG208A Visão geral
An FPGA is an integrated circuit that can be configured by the customer or designer after manufacturing—hence "field-programmable." FPGAs contain a fabric of programmable logic blocks and interconnects, allowing them to implement arbitrary digital logic functions. They sit between fixed-function ASICs and general-purpose processors, offering flexibility and parallel processing capabilities. The MX family is a mature, 5.0 V architecture optimized for high-volume applications where cost and reliability are paramount.
Key features of the A42MX24-PQG208A include 36,000 system gates, 912 logic modules, 176 user I/Os, and support for 5.0 V and 3.3 V mixed-voltage systems via MultiPlex I/Os. The device is fully compliant with the PCI Local Bus Specification (version 2.1), enabling direct interface to PCI buses without additional glue logic. It also features a low-power mode, making it suitable for power-sensitive designs.
Technically, the MX family uses a 0.45 µm process technology and supports system speeds up to 135 MHz. The device includes dedicated clock networks and programmable I/O standards, allowing flexible integration into various system architectures. The 208-pin PQFP package provides a compact footprint while offering ample I/O for medium-density logic designs.
Typical applications include industrial control, transportation systems, consumer electronics, and legacy PLD consolidation. The 5.0 V operation and PCI compliance make it ideal for interfacing with older 5 V logic families and PCI-based systems, while the low-power mode extends battery life in portable applications.
When designing with this FPGA, ensure proper decoupling of the 5.0 V supply and follow the manufacturer's layout guidelines for the PQFP package to minimize signal integrity issues. The device supports in-system programming, allowing firmware updates without removing the component from the PCB.

Aplicações típicas
A42MX24-PQG208A é adequado para 6 aplicaçãos: Industrial Control, Transportation Systems, Consumer Electronics, Legacy PLD Consolidation, PCI Interface, Test and Measurement.
Industrial Control
The A42MX24-PQG208A is well-suited for industrial control systems due to its 5.0 V operation, 176 I/Os, and 36K gates. It can implement motor control logic, PLC interfaces, and sensor processing. The device's PCI compliance enables direct connection to industrial PC backplanes, while the low-power mode reduces heat in sealed enclosures. Its commercial temperature range (0C to +70C) is adequate for most factory environments, and the high I/O count supports multiple peripheral interfaces.
Recomendado
Transportation Systems
In transportation applications such as railway signaling and automotive test equipment, the A42MX24-PQG208A provides reliable logic integration. Its 5.0 V compatibility with legacy systems simplifies upgrades, and the 176 I/Os allow interfacing with multiple sensors and actuators. The device's PCI compliance is beneficial for embedded computing modules. For outdoor or under-hood environments, consider the industrial temperature variant (A42MX24-PQG208I) to ensure operation from -40C to +85C.
Recomendado
Consumer Electronics
The A42MX24-PQG208A is used in consumer electronics for implementing user interface logic, display controllers, and audio processing. Its low-power mode extends battery life in portable devices, while the 5.0 V operation is compatible with many legacy power rails. The 176 I/Os provide ample connectivity for keypads, LEDs, and communication interfaces. The PQFP package is cost-effective for high-volume production, making it ideal for consumer products.
Recomendado
Legacy PLD Consolidation
The A42MX24-PQG208A is an ideal platform for consolidating multiple legacy PLDs into a single FPGA. With 36K gates and 912 logic modules, it can replace several PALs, GALs, and CPLDs, reducing board space and cost. The 5.0 V operation ensures compatibility with existing 5 V logic, and the 176 I/Os accommodate various signal interfaces. This consolidation simplifies BOM management and improves reliability by reducing component count.
Recomendado
PCI Interface
The A42MX24-PQG208A is fully compliant with the PCI Local Bus Specification (version 2.1), making it suitable for implementing PCI interface logic in embedded systems. Its 176 I/Os can be configured to meet PCI signaling requirements, and the 5.0 V operation matches PCI 2.1 voltage levels. This eliminates the need for external level shifters, simplifying design. The device's high gate count allows integration of PCI target or master functions alongside custom logic.
Recomendado
Test and Measurement
In test and measurement equipment, the A42MX24-PQG208A provides flexible logic for data acquisition, signal routing, and instrument control. Its 176 I/Os can interface with ADCs, DACs, and display modules, while the 36K gates handle complex timing and control logic. The 5.0 V operation is compatible with many analog front-ends, and the low-power mode reduces heat in benchtop instruments. The commercial temperature range is suitable for laboratory environments.

Notas de projeto
The A42MX24-PQG208A operates from a 5.0 V supply. Ensure the power supply is stable and well-regulated, with adequate decoupling capacitors (0.1uF and 10uF) placed close to each VCC pin. The device supports mixed-voltage I/Os (3.3V and 5.0V), so verify that I/O banks are configured correctly to avoid damage. Estimated: total power consumption depends on logic utilization and toggle rate; refer to the datasheet's power estimation section for accurate calculations.
For the 208-pin PQFP package, follow the manufacturer's recommended land pattern and keep traces short to minimize parasitic inductance. Use a solid ground plane and separate analog/digital grounds if mixed-signal interfaces are used. Ensure proper solder paste stencil design for fine-pitch leads to avoid bridging. The package has a 28x28 mm body with 0.5 mm lead pitch, so precise PCB fabrication is essential.
The PQFP package has limited thermal dissipation capability. Estimated: at 5.0 V and typical current draw of 100 mA, power dissipation is 0.5 W. With a theta_JA of approximately 40 C/W (typical for PQFP), the junction temperature rise is 20C above ambient. For high-utilization designs, ensure adequate airflow or add a heatsink. The commercial temperature range (0C to +70C) must not be exceeded.
