A42MX24-1PLG84 Visão geral
An FPGA (Field-Programmable Gate Array) is an integrated circuit that can be configured by the customer after manufacturing to implement any digital logic function. FPGAs belong to the programmable logic device (PLD) family, which sits above CPLDs in complexity and below ASICs in customization. The MX family is a high-volume, low-cost platform that bridges the gap between discrete logic and full-custom silicon, enabling rapid prototyping and flexible system design.
Key features include fast wide-decode circuitry similar to CPLD architectures, embedded dual-port SRAM modules optimized for high-speed datapath functions such as FIFOs and scratchpad memory, and support for 5V and 3.3V I/O standards. The device is manufactured using a 0.45um CMOS process, balancing performance with cost-effectiveness. The 84-pin PLCC package provides a compact footprint with J-lead terminations suitable for surface mounting.
Technically, the A42MX24 integrates D-modules arranged around the periphery, providing fast wide-input AND functions that accelerate control logic. The dual-port SRAM enables concurrent read/write operations, essential for buffering and data movement. The device supports in-system programming via JTAG, allowing flexible design updates without removing the component from the PCB.
Typical applications include industrial control systems, automotive electronics, communication interfaces, and legacy PLD consolidation. The 5V compatibility makes it ideal for interfacing with older 5V logic families, while the 3.3V option supports mixed-voltage designs. Its high I/O count and embedded memory suit bus interface and glue-logic applications.
When designing with this FPGA, ensure proper decoupling of both supply rails and follow the recommended power-up sequencing to avoid latch-up. The PLCC package requires a socket or reflow profile compatible with J-lead components. Thermal management is straightforward given the moderate power consumption of the 0.45um process.

Notas de projeto
The A42MX24-1PLG84 supports dual supply voltages: 3.3V (3.0V-3.6V) and 5V (4.75V-5.25V). Ensure both rails are properly decoupled with 0.1uF ceramic capacitors placed close to each VCC pin, and a bulk capacitor (10uF) on the board. The power-up sequence should avoid applying I/O voltage before the core supply to prevent latch-up. Refer to the Microchip 40MX and 42MX FPGA Families datasheet (DS2316) for recommended power supply decoupling and sequencing guidelines.
For the 84-PLCC package, ensure the PCB footprint matches the J-lead dimensions. Use a reflow profile suitable for J-lead components, and consider a socket for prototyping to avoid thermal stress. Provide adequate ground plane and thermal vias under the package to dissipate heat. Route high-speed signals with controlled impedance and minimize trace lengths to I/O pins. Follow the layout recommendations in the datasheet to reduce noise and crosstalk.
A common pitfall is neglecting the dual supply voltage requirements. The A42MX24-1PLG84 requires both 3.3V and 5V supplies; missing one can cause malfunction. Also, ensure JTAG pins (TDI, TDO, TMS, TCK) are properly terminated with pull-up resistors as recommended. Do not leave unused I/O pins floating; configure them as outputs or tie them to a defined level. Verify the speed grade (-1) meets your timing requirements; if not, consider a faster grade like -2 or -3.
