A42MX09-3PQ100

Overview

The A42MX09-3PQ100 is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microsemi. It features 684 Configurable Logic Blocks (CLBs) and approximately 14,000 system gates. The device supports a maximum clock frequency of 161 MHz with a CLB maximum combinatorial delay of 1.6 ns. It operates within a supply voltage range of 4.75 V to 5.25 V and includes 83 I/O pins. The component is housed in a PQFP-100 package and is rated for an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Flash-based non-volatile architecture enabling instant-on functionality without external configuration memory.
• Supports both 3.3 V and 5 V supply voltages for flexible interface compatibility.
• Includes hardware security features such as bitstream encryption and authentication.

Applications

• Industrial control systems requiring deterministic logic performance.
• Automotive electronics operating under extended temperature conditions.
• Military and aerospace applications utilizing radiation-tolerant or high-reliability components.

Procurement Notes

Verify the specific suffix '3PQ100' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Ensure compliance with RoHS directives if required by the target application. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly. Confirm availability status directly with authorized distributors as lead times may vary.

Selection Notes

Select this model when a moderate logic density of 14K gates is sufficient for the design. The PQFP-100 package is suitable for surface-mount applications where through-hole options are not preferred. Consider the 161 MHz speed grade for timing-critical designs. Verify that the 83 available I/O pins meet the interface requirements of the target system.

Part Context

This component belongs to the A42MX family of Flash FPGAs, which succeeded the Actel SmartFusion predecessor line. The MX series is characterized by its embedded Flash technology, eliminating the need for volatile configuration SRAM. This family is widely used in legacy system upgrades and new designs requiring high reliability and low power consumption.

Replacement Considerations

Direct replacements include other variants within the A42MX09 series with different speed grades or packages, such as A42MX09-3TQ100. For higher logic density, the A42MX16 series offers similar architecture with increased resources. Cross-family migration to newer Microchip FPGA lines requires significant design re-verification.
