A42MX16-2PQG100 概述
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer programs after manufacturing. Within the programmable logic hierarchy, the MX family sits as a low-cost, mature-platform FPGA bridging legacy PLD/CPLD integration and full-custom ASICs. The 42MX16 combines antifuse-style non-volatile programming heritage with Actel-proven architecture now maintained by Microchip Technology after the Microsemi acquisition.
Key features include 24K system gates of configurable logic, 83 user-programmable I/O pins, a -2 commercial speed grade, and lead-free, RoHS-friendly PQG100 packaging. The MX architecture enables consolidation of multiple legacy PAL/GAL/PLD devices into a single low-cost package, reducing board area, BOM count, and assembly cost.
The MX fabric balances logic density and routing flexibility, supporting glue logic, state machines, bus interfacing, and control-path functions commonly required in industrial and embedded systems. Because the family is mature and widely second-sourced through distribution, it remains a dependable choice for long-lifecycle programs where design continuity matters more than cutting-edge process nodes.
Typical applications include industrial control and automation glue logic, legacy PLD consolidation, communication backplane interface logic, defense and aerospace control circuits leveraging the Microsemi heritage, and embedded system peripheral control.
Design consideration: verify I/O voltage standards and power-up sequencing against the 40MX/42MX family datasheet (DS2136/DS2316), and confirm speed-grade timing models in Libero SoC before finalizing placement-critical designs.

典型应用
A42MX16-2PQG100 适用于 6 应用s: Legacy PLD Consolidation, Industrial Control and Automation Glue Logic, Aerospace and Defense Control Circuits, Communication Backplane Interface Logic, Embedded System Peripheral Control, ASIC Prototyping and Emulation.
Legacy PLD Consolidation
The A42MX16-2PQG100 is purpose-built to integrate multiple legacy PAL, GAL, and CPLD devices into a single 24K-gate FPGA. Its 5.0V-tolerant MX architecture interfaces directly with legacy 5V buses without level shifters, and its 83 I/O provide ample pin capacity to replace several 20-24 pin PLDs simultaneously. Consolidation reduces board area, BOM line items, and assembly cost while extending the life of proven legacy logic designs with a currently active, second-sourced part.
推荐
Industrial Control and Automation Glue Logic
In industrial controllers, the A42MX16-2PQG100 implements address decoding, bus bridging, handshaking, and state-machine logic between microprocessors and peripherals. The -2 speed grade provides adequate propagation delays for control-path timing at typical industrial clock rates, and 83 I/O accommodate parallel bus widths and discrete I/O. Its mature, fully characterized fabric ensures deterministic timing, while the 100-pin PQFP suits vibration-tolerant through-hole-adjacent assembly on standard industrial SMT lines.
推荐
Aerospace and Defense Control Circuits
The 42MX family carries Microsemi heritage in aerospace and defense, where long-lifecycle, well-characterized FPGAs are preferred. The A42MX16-2PQG100 serves in non-radiation-critical control, telemetry formatting, and interface logic. Military-suffix siblings such as the A42MX16-1PQG100M in the same 100-pin BQFP package allow a single board layout to serve commercial prototypes and qualifiable production builds, de-risking program logistics for long-duration defense platforms.
推荐
Communication Backplane Interface Logic
For telecom and datacom backplanes, the A42MX16-2PQG100 terminates parallel status/control buses, generates framing and handshaking signals, and bridges legacy line-card logic to modern controllers. The 24K-gate fabric accommodates multiple UART-style serializers or parallel port interfaces, and the 5.0V-tolerant I/O matches legacy backplane signaling standards directly, eliminating level-translation stages and their associated propagation delay and power cost.
推荐
Embedded System Peripheral Control
Embedded systems use the A42MX16-2PQG100 as a flexible peripheral controller: driving LCD timing, generating PWM channels, multiplexing sensor inputs, and implementing custom serial protocols. The reprogrammable fabric permits field design updates without PCB respins, while deterministic MX-family timing simplifies meeting real-time I/O deadlines. The 100-pin PQFP's 0.65mm-class lead pitch is reworkable with standard hot-air tools, easing low-volume embedded production.
推荐
ASIC Prototyping and Emulation
The MX family is positioned by Microchip as a single-chip ASIC alternative, making the A42MX16-2PQG100 useful for prototyping small ASIC control blocks and emulating gate-array netlists before committing to mask costs. Its 24K-gate capacity covers small state-machine-based ASIC functions, and the same die is offered across multiple packages (PQG100, TQG176, PQG208), letting designers trade I/O count and board area while keeping the validated programming file unchanged.

设计说明
The MX architecture is specified for a 5.0V supply environment. Confirm the exact VCC/VCCA/VCCI pin requirements and allowed tolerances in the 40MX/42MX families datasheet (DS2136 v16) before power tree design, and provide local 0.1uF decoupling at each supply pin plus bulk capacitance per Microchip power guidelines. Do not connect 3.3V-only drivers without verifying I/O compatibility.
Speed grade matters at the timing-closure stage: a design meeting timing on a -3 part may fail on the slower -1 grade, and a -2 part is not necessarily a substitution for a -3 in timing-critical paths. Always re-run static timing analysis in Microchip Libero SoC with the correct speed-grade model after any grade substitution, and verify unused I/O termination settings per the datasheet.
The 100-pin BQFP has leads on four sides with relatively fine pitch; use a footprint matching the datasheet package drawing exactly, with no-clean flux compatible with lead (G suffix) plating. Thermal relief: the BQFP has no exposed pad, so heat removal is via leads - keep trace widths generous on power rails and avoid placing high-current devices directly beneath the package.
合规信息
The G suffix in PQG100 denotes lead-free plating per distributor listings (PCB Electronics lists the part as LEAD FREE). Formal RoHS/REACH declarations were not present in verified data - obtain from Microchip product page.
