Typical Applications

A42MX09-PQ100I is suitable for 6 applications: Legacy PLD/CPLD Consolidation, Industrial Control and Automation, Automotive In-Cabin Telematics, Bus Interface and Glue Logic, Dual-Port SRAM Buffering and FIFOs, ASIC Prototyping and Low-Volume Production.

πŸ”§

Legacy PLD/CPLD Consolidation

The MX family was explicitly designed to integrate logic currently spread across multiple CPLDs or PLDs into a single chip. The A42MX09-PQ100I offers 14,000 gates and 684 logic cells with 100% resource utilization and 100% pin locking, so a multi-PLD board can be collapsed onto one 100-pin PQFP without timing closure surprises. Its antifuse, non-volatile configuration removes the external configuration PROM required by SRAM FPGAs, saving board space and BOM cost. Its 5V/3.3V dual rails also interface directly with legacy 5V bus logic common in older systems being redesigned.

🏭

Industrial Control and Automation

The -I industrial temperature rating of -40C to +85C makes the A42MX09-PQ100I suitable for factory automation controllers, motor drive interface logic, and process control I/O modules. The deterministic antifuse routing eliminates configuration-time delay and provides instant-on operation after power-up, which matters in machinery requiring immediate handshake logic. With 83 user I/O and fast wide-decode circuitry, address decoding and bus interfacing for backplane systems are natural fits. Dual 3.3V/5V supply operation lets one device bridge modern 3.3V microcontroller peripherals and legacy 5V industrial sensors.

πŸš—

Automotive In-Cabin Telematics

Per the 40MX/42MX Automotive FPGA Families datasheet, the MX family targets in-cabin telematics and automobile interconnect applications as a cost-effective ASIC alternative. While the PQ100I itself is industrial grade, the same die in the A42MX09-FPQ100I variant carries automotive qualification in the identical PQ100 footprint. Designers prototyping automotive logic consolidation can develop on the PQ100I and migrate to the FPQ part for production. The 2.5 kbit dual-port SRAM supports buffer FIFOs between telematics processors and body-domain I/O.

πŸ–₯️

Bus Interface and Glue Logic

The fast wide-decode circuitry of the 42MX family makes the A42MX09-PQ100I well suited to address decoding, bus bridging, and wait-state generation between processors and peripherals. With system frequencies up to 129 MHz on the fastest grades and deterministic antifuse routing, decode paths have fixed, predictable propagation delay - an advantage over SRAM FPGAs whose routing varies at compile time. The 83 user I/O pins in a 0.65 mm-pitch 100-pin PQFP provide enough connectivity for 16- or 32-bit bus interfaces plus control strobes on a single chip.

🧩

Dual-Port SRAM Buffering and FIFOs

The A42MX09-PQ100I provides up to 2.5 kbits of configurable dual-port SRAM, enabling clock-domain crossing FIFOs, ping-pong buffers, and shared-memory handshakes entirely on-chip. This eliminates external dual-port SRAM devices, reducing board area and cost in data-acquisition and telemetry front ends. Because the antifuse fabric is non-volatile, buffer logic is live immediately at power-up. The deterministic timing also simplifies FIFO flag timing analysis at the approximately 129 MHz system rates the family supports on fast speed grades.

πŸ”§

ASIC Prototyping and Low-Volume Production

The MX family is positioned by Microchip as a reliable single-chip ASIC alternative for high-volume, cost-sensitive systems. Designers can use the A42MX09-PQ100I to prototype and even ship low-to-mid-volume products that would otherwise require an ASIC mask set, avoiding NRE charges. One-time antifuse programming means there is no configuration file to steal, providing design security SRAM FPGAs cannot match. At 14,000 gates, the device accommodates moderate state machines, bus logic, and datapath functions typical of ASIC replacements.

What are the key specifications of A42MX09-PQ100I?
The A42MX09-PQ100I is a 14,000-gate antifuse FPGA with 684 logic cells, 83 user I/O, and up to 2.5 kbits of dual-port SRAM. Per the Microchip MX datasheet, it runs on dual rails of 3.0-3.6V and 4.5-5.5V, operates from -40C to +85C, and comes in a 100-pin PQFP with 0.65 mm pitch. It uses 0.45 um CMOS and is currently obsolete.
Where can I buy A42MX09-PQ100I?
The A42MX09-PQ100I is listed by distributors including DigiKey, Mouser, and Microchip USA, but Microchip marks the part Obsolete with no manufacturer lead time available, so stock is last-time-buy only. XAIPART offers sourcing support for this MPN; request a quote for current inventory and pricing as of 2026-08-30.
What is the price of A42MX09-PQ100I?
Current pricing for the obsolete A42MX09-PQ100I varies by distributor stock and is not published in a standard price ladder; verify live pricing as of 2026-08-30. Because the part is RoHS non-compliant and obsolete, remaining inventory typically trades at a premium to original list. Request a quote from XAIPART for a firm price.
Is A42MX09-PQ100I still in production?
No. According to Microchip USA product data, the A42MX09-PQ100I is marked Obsolete with no lead time information available, and it is RoHS non-compliant. The same die remains available in the RoHS-compliant A42MX09-PQG100I green-package variant for new or continuing production needs.
What is the difference between A42MX09-PQ100I and A42MX09-PQG100I?
The two parts share the same die, gate count, I/O, and 100-pin PQFP footprint; the difference is the package plating. The PQG100I uses a green, RoHS-compliant finish, while the PQ100I is RoHS non-compliant and obsolete. For new designs or lead-free assembly lines, the PQG100I is the correct drop-in choice.
Can A42MX09-PQ100I be replaced by a drop-in replacement?
Yes, within the same family. The A42MX09-1PQ100I (faster speed grade), A42MX09-PQG100I (RoHS-compliant green package), and A42MX09-FPQ100I (automotive grade) are pin-to-pin compatible on the same 100-pin PQ100 footprint. No cross-brand drop-in equivalent exists because the Actel/Microchip antifuse architecture is proprietary; see the alternatives table for details.
What is the best Xilinx equivalent for A42MX09-PQ100I?
There is no true cross-brand pin-compatible equivalent for the A42MX09-PQ100I. Xilinx and Altera SRAM FPGAs of similar density (e.g., XC4000-series class devices) use different packages, pinouts, and volatile configuration schemes, so a PCB redesign and external configuration device would be required. The practical replacement path is within the Microchip MX family itself.
When should I choose A42MX09-PQ100I over A42MX16-PQ100?
Choose the A42MX09-PQ100I when 14,000 gates suffice and cost or existing BOM qualification matters; choose the A42MX16-PQ100 when you need more logic density, since it uses the same PQ100 0.65 mm footprint with a larger die. Both are obsolete 5V/3.3V antifuse FPGAs, so new designs should instead target the PQG100 green variants.
Where can I download the A42MX09-PQ100I datasheet PDF?
The official datasheet is the 40MX and 42MX FPGA Families document, available from the Microchip product page (microchip.com/en-us/product/A42MX09) and mirrored by Mouser as MX_Auto_DS.pdf. Archived Actel datasheets are also available on alldatasheet.com. The PDF covers both the standard and automotive MX families.
How is the A42MX09-PQ100I powered?
It uses a dual-rail scheme: VCCI of 3.0V to 3.6V and VCL of 4.5V to 5.5V, per the Microchip MX family datasheet. This lets designers interface directly with legacy 5V logic while running the I/O ring at 3.3V. Decouple both rails with 0.1 uF ceramic capacitors close to the package power pins.
Hey Google, is A42MX09-PQ100I the same as A42MX09-PQ100?
Almost - the I suffix matters. The A42MX09-PQ100I is the industrial temperature grade rated -40C to +85C, while the A42MX09-PQ100 (no I) is the commercial grade rated 0C to +70C. They share the same 14K-gate die and 100-pin PQFP footprint, but the commercial part cannot be used where industrial temperature is required.
Is A42MX09-PQ100I suitable for automotive applications?
Not directly. The standard PQ100I is an industrial-grade part, not automotive qualified. For in-cabin telematics and automobile interconnect designs, Microchip offers the A42MX09-FPQ100I automotive variant of the same 14K-gate die in the same 100-pin PQFP footprint, per the 40MX/42MX Automotive FPGA Families datasheet.
What tools are used to program the A42MX09-PQ100I?
Designs are developed in Microchip (formerly Microsemi/Actel) Libero SoC design software and programmed via the antifuse programming interface used across the MX family. Because antifuse programming is one-time, verify the design fully in simulation before programming production devices. Legacy Designer series software also supports MX.

Selection Guide

Choose the A42MX09-PQ100I only when you must maintain an existing qualified legacy BOM at industrial temperature, since the part is obsolete and RoHS non-compliant. For new builds on the same 100-PQFP footprint, select the A42MX09-PQG100I (RoHS-compliant green package, active status) as the primary drop-in. Pick the A42MX09-1PQ100I when your design needs extra timing margin from the faster speed grade, and the A42MX09-FPQ100I for automotive-qualified production. If 14,000 gates are insufficient, the A42MX16-PQ100 doubles density on the identical footprint, but note its commercial temperature range - verify your thermal environment before substituting. Cross-brand replacement is not practical: competing SRAM FPGAs require PCB rework and an external configuration device, defeating the MX family's single-chip, instant-on value proposition.

Key Differentiators

  • Non-volatile antifuse, single-chip configuration (vs A42MX16-PQ100)
  • RoHS-compliant green package option on same footprint (vs A42MX09-PQG100I)
  • Automotive-qualified same-die variant available (vs A42MX09-FPQ100I)
  • Faster speed grade on same footprint (vs A42MX09-1PQ100I)

Design Notes

The A42MX09-PQ100I uses a dual-rail architecture: VCCI 3.0-3.6V and VCL 4.5-5.5V per the MX datasheet. Decouple both rails with at least 0.1 uF ceramic capacitors placed within 5 mm of the package power pins, plus bulk 10 uF per rail. Because the antifuse fabric draws near-zero static configuration current unlike SRAM FPGAs, the power tree is simple, but 5V rail integrity directly affects output edge rates on 5V-tolerant I/O banks.

Antifuse FPGAs are one-time programmable: a design error permanently consumes a device. Verify timing and functional simulation completely in Microchip Libero SoC before programming production parts, and program one verification unit before committing a batch. Additionally, this PQ100I variant is RoHS non-compliant - it cannot be used in assemblies requiring lead-free process compliance; substitute A42MX09-PQG100I on the same footprint.

The 0.65 mm-pitch PQ100 package with 83 user I/O at up to ~129 MHz system speeds needs controlled stub lengths on bus lines. Keep address/data traces under 10 cm where practical and series-terminate 33-50 ohm on clock outputs. Deterministic antifuse routing means board-level timing extracted from Libero holds for the life of the design - re-verify only when changing speed grade.

The obsolete, RoHS non-compliant PQ100I finish may not be compatible with lead-free reflow profiles required by modern SMT lines. Confirm your assembly process allows leaded parts, or redesign the BOM to the A42MX09-PQG100I green variant, which is footprint-identical. Standard PQ100 land pattern per IPC-SM-782 applies for the 0.65 mm pitch quad flat pack.
