A42MX09-PQ100I Descripción general
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs) and interconnects that the designer programs to implement custom digital logic, serving as a single-chip ASIC alternative. The 42MX family belongs to the broader category of programmable logic devices (PLDs), positioned between CPLDs and modern SRAM-based FPGAs in the power management and embedded logic hierarchy.
Key features include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, up to 100% resource utilization, and 100% pin locking with deterministic timing. The antifuse architecture is non-volatile and inherently single-chip, requiring no external configuration PROM and offering better security and instant-on behavior than SRAM FPGAs. The 0.45 um CMOS process supports system clock frequencies up to 129 MHz/215 MHz depending on the speed grade and routing.
The MX family is explicitly designed as a single-chip ASIC alternative, ideal for consolidating legacy PLD/CPLD logic into one low-cost, high-volume device. The -I suffix denotes industrial temperature qualification, and automotive-grade variants (FPQ) exist for in-cabin telematics and automobile interconnect applications.
Typical applications include glue logic integration, legacy PLD consolidation, bus interfacing, industrial control, and automotive interconnect systems where a 5V-tolerant, non-volatile FPGA simplifies the power tree.
Design consideration: this specific PQ100I variant is marked RoHS non-compliant and obsolete by Microchip, so new designs should target the PQG100I (green package) variant, while existing designs should secure last-time-buy inventory.

Aplicaciones típicas
A42MX09-PQ100I es adecuado para 6 aplicacións: 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.
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.
Recomendado
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.

Notas de diseño
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.
Información de cumplimiento
Per Microchip USA product data: RoHS Status RoHS non-compliant; Product Status Obsolete. AEC-Q100 qualification applies to the FPQ automotive variants, not this industrial-grade part.
