A42MX16-1PQG100 - 24K Gate MX FPGA, 83 I/O | Microchip
MPN: A42MX16-1PQG100 ✓ Hoạt độngA42MX16-1PQG100 Tóm tắt
An FPGA (Field Programmable Gate Array) is a semiconductor device containing configurable logic blocks and programmable interconnects that the designer wires together after manufacturing, in contrast to fixed-function ASICs. Within the programmable logic hierarchy, the MX family sits as a one-time-programmable (OTP) FPGA platform, positioned between CPLDs and large SRAM-based FPGAs, and is widely used to consolidate legacy PLD and glue-logic designs into a single low-cost, high-volume device.
Key characteristics of the A42MX16 include 24K system gates, 83 available I/O, the Actel antifuse architecture with non-volatile configuration (no external boot PROM required), and 5.0 V tolerant operation suited to legacy industrial system voltages. The -1 speed grade targets commercial temperature applications. Because configuration data is stored in antifuse elements, the device is inherently secure and immune to configuration-readback attacks and radiation-induced configuration upsets compared with SRAM FPGAs.
Architecturally, MX devices combine fine-grained logic modules (ACT modules) with embedded decoding and wide-decode capability, allowing efficient implementation of state machines, bus interfaces, and legacy 5V logic replacement. The PQFP-100 package offers a practical 0.65 mm lead pitch for hand-assembly-friendly prototype and repair workflows common in industrial maintenance.
Typical applications include legacy PLD consolidation, industrial control and automation boards, 5V bus interface bridging, aerospace/defense obsolescence management designs, and high-volume cost-sensitive logic integration. Engineers choose MX devices precisely because they bridge aging 5V systems to long-term production with a stable, single-chip solution.
Design consideration: because MX antifuse devices are one-time programmable, thoroughly verify the design in simulation before programming; provide the 5.0 V supply with adequate decoupling and follow the pinout table in datasheet DS2136 when assigning I/O.

Ứng dụng tiêu biểu
A42MX16-1PQG100 phù hợp cho 6 Áp dụngs: Legacy PLD Consolidation, Industrial Control and Automation, Obsolescence Management for Defense Systems, 5V Bus Interface Bridging, High-Volume Cost-Sensitive Logic Integration, Test and Measurement Instrument Logic.
Legacy PLD Consolidation
The A42MX16-1PQG100 is purpose-built for consolidating multiple legacy PLDs, GALs, and TTL glue-logic devices into a single low-cost 24K-gate FPGA. Its native 5.0 V architecture directly replaces aging 5V logic families without level translation, cutting board area and BOM count. In a typical consolidation, two to five 22V10-class PLDs plus address decoders fit into the 24K gates with margin. Because the antifuse configuration is non-volatile, no configuration PROM is needed on the bill of materials, keeping the replacement cost and provisioning simple for long-life production programs.
Được đề xuất
Industrial Control and Automation
In industrial control and automation boards, the A42MX16-1PQG100 implements state machines, motor-control sequencing, and bus-interface logic that must tolerate 5V signaling environments. The 83 user I/O provide sufficient pin count for parallel fieldbus interfaces and sensor polling, while the -1 commercial speed grade comfortably meets sub-100 MHz control logic timing. Antifuse configuration is immune to power-glitch corruption, an important reliability trait on factory floors with unstable power, and IEEE 1149.1 JTAG boundary scan supports in-circuit production test of assembled control boards.

Obsolescence Management for Defense Systems
Defense and avionics sustainment programs use the A42MX16-1PQG100 and its military-grade siblings to keep legacy 5V programmable logic in production after original PLD vendors exit the market. Microchip maintains the MX family specifically as a long-term platform for such programs. The 100-pin PQFP with gull-wing leads is easy to inspect and rework during depot-level repair, and the one-time-programmable antifuse technology provides inherent tamper resistance and configuration security valued in defense platforms where configuration readback must be impossible.
Được đề xuất
5V Bus Interface Bridging
The device serves as a bridge between legacy 5V parallel buses (VME-style backplanes, ISA-derived interfaces) and newer subsystem logic. With 83 I/O operating at 5.0 V, it drives and receives TTL-level signals directly, eliminating bus transceiver banks. The MX architecture's wide-decode capability implements address decoding and chip-select generation efficiently in the 24K gates. Designers should budget I/O clamp considerations and follow datasheet DS2136 DC specifications for VOH/VOL at required drive currents to guarantee bus timing margins across the commercial temperature range.
Được đề xuất
High-Volume Cost-Sensitive Logic Integration
For consumer and industrial products in volumes above roughly 10K units per year, the A42MX16-1PQG100 functions as a low-cost single-chip ASIC alternative: no NRE mask charges, immediate design changes, and non-volatile configuration that removes firmware provisioning from the assembly line. The antifuse technology makes cloned re-programming impossible, protecting logic IP in cost-sensitive markets. At the ~$258 unit price point as of 2026-08-30 it targets programs where reliability and IP security outweigh the per-unit cost of modern low-voltage FPGAs.
Được đề xuất
Test and Measurement Instrument Logic
Benchtop instruments and rack-mounted test equipment use the A42MX16-1PQG100 for timing sequencers, trigger logic, and interface glue logic that must remain fixed and deterministic across production units. The one-time-programmable nature guarantees identical configuration in every shipped unit - no firmware corruption risk in the field. JTAG boundary scan (IEEE 1149.1) enables full board interconnect testing during instrument calibration, and the 5.0 V I/O directly interfaces the legacy backplane and front-panel signaling common in long-lived instrument platforms.

Ghi chú thiết kế
The MX family operates from a single 5.0 V supply. Decouple each VDD pin of the PQ-100 package with 0.1 uF ceramic capacitors placed within 5 mm of the pin, plus bulk 10 uF tantalum per supply rail. Current consumption depends on toggling activity; obtain dynamic current estimates from the Microchip Designer tool power calculator rather than assuming worst-case datasheet numbers, and size the 5V regulator with margin for simultaneous output switching.
This is a one-time-programmable antifuse FPGA - a programmed device can never be reprogrammed. Complete full functional simulation and static timing analysis in Microchip Libero/Designer before releasing a design to Silicon Sculptor programming. Do not treat the -1 speed grade as interchangeable with -2 parts in timing-critical paths; check AC timing tables in datasheet DS2136 for your actual operating conditions.
With 83 5.0 V CMOS I/O, ground bounce can be significant when many outputs switch simultaneously. Assign high-toggle-rate signals near GND pins, use the MX family's programmable output slew-rate options to slow non-critical edges, and maintain a solid, unbroken ground plane under the PQFP. Follow Microchip MX application notes for recommended max simultaneous switching output counts per ground pin.
