A42MX09-1TQG176M

Overview

The A42MX09-1TQG176M is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features up to 9,000 system gates and 336 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with core voltages of 5.0V or 3.3V and PCI-compliant I/Os. Key performance metrics include a maximum clock frequency of 117 MHz and a CLB maximum combinatorial delay of 3.5 ns. It offers up to 2.5 kbits of configurable dual-port SRAM and up to 176 user-programmable I/O pins. The component operates within a temperature range of -40°C to +85°C and is housed in a TQFP-176 package.

Feature Summary

• Provides deterministic, user-controllable timing for precise design implementation.
• Supports mixed-voltage operation allowing flexible integration of 5.0V and 3.3V logic levels.
• Enables up to 100% resource utilization and complete pin locking capabilities.

Applications

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

Procurement Notes

Verify the specific suffix '1' indicates the required speed grade against official datasheets. Confirm the 'M' suffix denotes industrial temperature range compliance. Ensure the TQFP-176 package matches the target PCB footprint. Check for RoHS compliance status in current documentation. Validate that the manufacturer source is recognized for this legacy series.

Selection Notes

Select this model when a cost-effective single-chip solution replaces multiple PALs, CPLDs, or FPGAs. Choose based on the requirement for up to 9,000 system gates and 176 I/Os. Consider the 117 MHz performance limit for timing closure. Evaluate the need for mixed-voltage I/O support. Verify thermal requirements fit the industrial temperature range specifications.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families. These devices are engineered to consolidate logic previously implemented in discrete components. The family provides high performance while shortening system design cycles. They serve as direct replacements for complex programmable logic solutions.

Replacement Considerations

Public confirmed substitute part numbers: A42MX09-PQFP176, A42MX09-TQFP176I. Verify pin compatibility and gate count equivalence before substitution.
