A42MX09-2PQG100 Übersicht

The Microchip Technology A42MX09-2PQG100 is a field-programmable gate array (FPGA) from the MX family, offering 14,000 system gates and 83 user I/O pins in a 100-pin PQFP (PQG100) package. It operates from a 5.0 V supply and provides a single-chip ASIC alternative for integrating legacy PLDs. The device features 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, and up to 202 user-programmable I/O pins across the family. With a clock-to-out time of 5.6 ns and 250 MHz performance, it suits high-speed logic integration.

An FPGA is a semiconductor device containing programmable logic blocks and interconnects that can be configured after manufacturing to implement custom digital circuits. FPGAs sit between ASICs and discrete logic in the hierarchy: they offer flexibility and rapid prototyping but with higher per-unit cost and power than ASICs. The MX family is optimized for 5.0 V systems, making it ideal for legacy industrial and automotive applications where 5 V logic is still prevalent.

Key features include 14,000 system gates, 83 user I/O pins, 2.5 kbits dual-port SRAM, and 5.6 ns clock-to-out. The device supports 5.0 V operation and is lead-free (RoHS compliant). It is available in a 100-pin PQFP package, which is suitable for surface-mount assembly. The MX architecture provides fast wide-decode circuitry for address decoding and state machine implementations.

Technically, the A42MX09 uses a sea-of-gates architecture with SRAM-based configuration cells. It offers 250 MHz internal performance and 100 MHz FIFO operation. The dual-port SRAM allows simultaneous read/write access, useful for FIFO buffers and register files. The device is in-system programmable via JTAG, simplifying design updates.

Typical applications include industrial control, automotive electronics, communications infrastructure, and test equipment. Its 5.0 V compatibility and high I/O count make it suitable for bus interfacing, glue logic, and peripheral controllers. The 83 I/O pins can interface with 5 V TTL/CMOS logic directly.

When designing with this FPGA, ensure proper decoupling of the 5.0 V supply and follow the recommended power-up sequence. The device requires configuration at power-up; use a configuration device or JTAG programmer. Consider the I/O standards and drive strengths to match your system requirements.

The -2PQG100 is a 100-pin PQFP with 83 user I/O pins, while the -2PQG160 is a 160-pin PQFP with more I/O pins (typically 125). The -2PQG160 offers more I/O for designs requiring additional connections, but the -2PQG100 is more compact and cost-effective for lower I/O requirements.

When should I choose A42MX09-2PQG100 over A42MX09-2PQG160?

Choose the A42MX09-2PQG100 when your design requires 83 or fewer I/O pins and you prefer a smaller, lower-cost 100-pin package. It is ideal for space-constrained boards and applications where the I/O count is sufficient. Choose the A42MX09-2PQG160 if you need more I/O pins (up to 125) for larger bus interfaces or additional peripherals. The -2PQG160 is also suitable for designs that may require future I/O expansion.

What is the best drop-in replacement for A42MX09-2PQG100?

The best drop-in replacement for A42MX09-2PQG100 is the A42MX09-2PQG100I, which is the industrial temperature grade version (-40C to +85C) in the same 100-pin PQFP package. It is pin-to-pin compatible and offers identical logic resources. Other drop-in options include the A42MX09-2PQG100M (military grade) and the A42MX09-3PQG100 (faster speed grade). All share the same footprint and are available from Microchip.

Can A42MX09-2PQG100 be replaced by A42MX09-2PQG100I?

Yes, the A42MX09-2PQG100I is a direct drop-in replacement for the A42MX09-2PQG100. Both are in the same 100-pin PQFP package and have identical pinout and logic resources. The -I suffix indicates industrial temperature range (-40C to +85C) instead of commercial (0C to +70C), making it suitable for harsher environments. The electrical specifications are otherwise the same, so you can swap them without PCB changes.

Where can I download the A42MX09-2PQG100 datasheet PDF?

The A42MX09-2PQG100 datasheet is available from Microchip's official product page at https://www.microchip.com/en-us/product/A42MX09. It is also hosted on third-party sites like alldatasheet.com, which provides a 173-page PDF titled '40MX and 42MX FPGA'. For the most authoritative version, download directly from Microchip's website to ensure you have the latest revision.

Where can I find the A42MX09-2PQG100 pinout?

The A42MX09-2PQG100 pinout is detailed in the official datasheet, which is available from Microchip's product page. The 100-pin PQFP package has 83 user I/O pins, with the remaining pins used for power, ground, and configuration. The pinout diagram is provided in the datasheet's package section. You can also find pinout information on distributor sites like Mouser and DigiKey, but the datasheet is the authoritative source.

What are the key specifications of A42MX09-2PQG100 that engineers should know?

Engineers should know that the A42MX09-2PQG100 is a 5.0 V FPGA with 14,000 system gates, 83 user I/O pins, and 2.5 kbits of dual-port SRAM.

Designhinweise

The A42MX09-2PQG100 operates from a 5.0 V supply. Ensure adequate decoupling with 0.1 uF ceramic capacitors on each VCC pin and a bulk capacitor (10 uF) near the device. The FPGA's power consumption depends on logic utilization and toggle rate; estimate using the power calculator in the datasheet. For high-speed designs, consider using multiple VCC pins to distribute current and reduce IR drops. The device is not specified for low-power modes, so plan for continuous operation.

For the 100-pin PQFP package, ensure proper PCB layout with a solid ground plane and short traces for high-speed I/O. Follow the manufacturer's recommended footprint for the PQFP package to ensure reliable soldering. Place decoupling capacitors as close to the VCC pins as possible. For the 5.0 V supply, use wide traces to minimize voltage drop. Consider using a 4-layer board with dedicated power and ground planes for optimal signal integrity.

A common pitfall is forgetting to configure the FPGA at power-up. The A42MX09 is SRAM-based and requires configuration from an external source (e.g., a configuration PROM or JTAG). Ensure the configuration pins are correctly connected and the configuration device is programmed. Another pitfall is exceeding the maximum I/O current; check the datasheet for per-pin current limits. Also, verify that the 5.0 V supply is within the specified range (typically 4.75V to 5.25V) to avoid erratic behavior.
