A42MX09-1PQG160I

Overview

The A42MX09-1PQG160I is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX series, originally developed by Actel. It features 336 Configurable Logic Blocks (CLBs), equivalent to 14,000 system gates, and provides 101 user-programmable I/O pins. The device operates within a supply voltage range of 4.75V to 5.25V for the core and supports mixed-voltage operation at 3.3V for I/Os. It is housed in a 160-pin Plastic Quad Flat Package (PQFP) with dimensions of 28x28 mm. The component supports a maximum clock frequency of 70.2 MHz and has a CLB combinational delay of 3.5 ns. It is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• Supports mixed-voltage operation allowing 5.0V or 3.3V core and I/O configurations with PCI-compliant I/Os.
• Enables 100% resource utilization and 100% pin locking for deterministic, user-controllable timing.
• Functions as a single-chip ASIC alternative with up to 2.5 kbits of configurable dual-port SRAM.

Applications

• Replacement for complex ASICs in embedded systems requiring low power and high density.
• Prototyping and development of digital logic circuits using mixed-voltage interfaces.
• Implementation of deterministic timing applications requiring full pin locking capabilities.

Procurement Notes

This specific part number is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or secondary markets rather than direct factory orders. Buyers must confirm the authenticity of the source and check for any relevant Product Change Notifications (PCNs) regarding assembly site changes or material substitutions that may affect compliance with RoHS or REACH standards.

Selection Notes

When selecting this FPGA, verify that the application requires the specific 160-pin PQFP package and 101 I/O count. Ensure the design utilizes the 5V core voltage range or confirms compatibility with the 3.3V I/O mixed-mode operation. Designers should account for the commercial temperature grade limits and ensure the PCB layout accommodates the 28x28 mm footprint and moisture sensitivity level requirements during storage and reflow soldering.

Part Context

The A42MX09 belongs to the Actel MX family of FPGAs, which were acquired by Microchip Technology. This series is characterized by its non-volatile flash-based technology, offering instant-on capability and high radiation tolerance options. The A42MX09 specifically targets applications needing moderate logic density with robust I/O flexibility, bridging the gap between CPLDs and larger FPGAs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the obsolete status of the A42MX09 series. Engineers should consult Microchip's official obsolescence notices for potential migration paths to newer FPGA families such as the PolarFire or IGLOO series, though these require significant design adaptation.
