A42MX09-PLG84

Overview

The A42MX09-PLG84 is a field-programmable gate array from the Microchip A42MX09 series, designed as a single-chip ASIC alternative. It features 336 logic elements and approximately 14,000 system gates. The device provides 72 input/output pins and operates with a minimum supply voltage of 4.75 V and a maximum of 5.25 V. It supports mixed-voltage operation for core and I/Os at 3.3 V or 5.0 V. The component is housed in a PLCC-84 package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Single-chip solution integrating logic previously implemented in multiple PALs, CPLDs, and FPGAs
• Supports mixed-voltage operation with PCI-compliant I/Os
• Enables up to 100% resource utilization and pin locking

Applications

• High-speed controllers
• Address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify current lifecycle status before procurement, as the A42MX09 series has been subject to discontinuation notices by the manufacturer. Confirm that the specific PLCC-84 variant meets all electrical and environmental requirements for the target application. Ensure compatibility with existing design tools and programming hardware. Check for availability of last-time buy options if long-term supply is required.

Selection Notes

Select this model when a low-pin-count FPGA with moderate logic capacity is needed for 5V or 3.3V systems. The PLCC-84 package suits designs requiring through-hole or standard surface-mount assembly without fine-pitch constraints. Consider the 336 LE count against complex logic requirements. Verify that the commercial temperature range aligns with the operational environment.

Part Context

The A42MX09-PLG84 belongs to the Actel MX family, which bridges the gap between simple programmable logic devices and complex FPGAs. This series emphasizes deterministic timing and high reliability. The PLG84 suffix denotes the Plastic Leaded Chip Carrier package with 84 leads, providing a compact form factor for space-constrained embedded applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The A42MX09 series has faced end-of-life notifications. Designers should consult Microchip Technology for recommended migration paths or equivalent components within updated product lines.
