A42MX09-PQG100I

Overview

The A42MX09-PQG100I is a Flash-based Field Programmable Gate Array from the Microchip Actel MX series. It features 336 Logic Elements and approximately 14,000 system gates within a PQFP-100 package. The device supports mixed-voltage operation with core and I/O supplies ranging from 3.3V to 5.5V. It operates reliably across an industrial temperature range of -40°C to +85°C. Key specifications include up to 83 user-programmable I/O pins and non-volatile Flash technology for instant-on functionality without external configuration memory.

Feature Summary

• Instant-on capability provided by non-volatile Flash architecture, eliminating the need for external configuration PROMs.
• Supports mixed-voltage operation allowing flexible integration with both 3.3V and 5V logic interfaces.
• Enables 100% resource utilization and deterministic timing through full pin locking capabilities.

Applications

• Replacement for complex discrete logic or ASICs in industrial control systems
• Interface bridging between different voltage domains in embedded systems
• Prototyping and low-volume production for aerospace and defense electronics

Procurement Notes

Verify the specific speed grade suffix (e.g., -1, -2) against design timing requirements, as performance varies within the A42MX09 family. Confirm RoHS compliance status for the specific manufacturing lot if required by environmental regulations. Ensure ESD precautions are taken during handling due to moisture sensitivity level 3 classification. Cross-reference the manufacturer part number with distributor codes to avoid confusion with similar packages.

Selection Notes

Select this component when a small-scale FPGA with instant-on Flash technology is required. Compare logic density against the A40MX02 or A42MX16 if gate count requirements change. Verify that the PQFP-100 footprint matches the PCB layout constraints. Consider the operating voltage range to ensure compatibility with existing power rails without additional level shifters.

Part Context

This part belongs to the Actel MX family, acquired by Microchip Technology. The A42MX09 represents a mid-range density option within the series, balancing gate count with power consumption. It utilizes proprietary Flash processes distinct from SRAM-based FPGAs, offering radiation tolerance and security advantages suitable for harsh environments.

Replacement Considerations

Direct substitutes include other A42MX09 variants with different speed grades or package options, such as A42MX09-1PQG100I. Generic FPGA replacements require significant redesign of logic and timing constraints.
