A42MX16-2PQG160I - 24K Gate 5V FPGA 160-PQFP | Microchip
MPN： A42MX16-2PQG160I ✓ 啟用中A42MX16-2PQG160I 概覽
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) and programmable interconnects that engineers configure in the field after manufacturing. FPGAs sit within the programmable logic hierarchy alongside CPLDs and ASICs, offering a single-chip ASIC alternative for mid-volume designs. The MX family is specifically positioned for 5.0V legacy integration, allowing designers to consolidate legacy PLD/CPLD logic into one low-cost, high-reliability device.
Key features include a flexible 5.0V-tolerant architecture, 125 user I/O in the 160-BQFP package, dual-voltage 3.3V/5V operation, and antifuse-based one-time-programmable (OTP) configuration that provides instant-on power-up, high radiation tolerance, and no external configuration PROM - a hallmark of the Microsemi MX product line.
The 0.45um CMOS process implements the Actel antifuse programmable interconnect, delivering true single-chip operation with minimal standby power and superior resistance to configuration upset compared to SRAM-based FPGAs. Speed grade -2 supports internal toggle rates cited as 129MHz/215MHz in distributor data.
Typical applications include legacy system consolidation, industrial control, military/aerospace upgrades, motor control glue logic, and 5V bus bridging where SRAM FPGA configuration storage is undesirable.
Design consideration: as an OTP antifuse device, the design must be final before programming - plan programming via the Microchip FlashPro/Libero flow and verify I/O assignments against the 160-PQFP pinout before committing.

典型應用
A42MX16-2PQG160I 適用於 6 應用s: Legacy System Logic Consolidation, Industrial Motor Control Sequencing, Military and Aerospace System Upgrades, 5V Industrial Bus Bridging, Test and Measurement Instrumentation, In-Cabin Automotive Telematics Interfaces.
Legacy System Logic Consolidation
The A42MX16-2PQG160I is explicitly positioned by Microchip as a single-chip ASIC alternative for consolidating legacy PLD, CPLD, and SSI/MSI glue logic into one device. Its 24,000 gates, 1,232 logic cells, and 125 user I/O in the 160-PQFP absorb multiple 5V legacy devices, while the antifuse OTP configuration powers up instantly with no external configuration PROM. The 3.3V/5V dual-supply operation lets it sit directly on legacy 5V buses, reducing board area, inventory, and power versus discrete TTL/CPLD stacks.
推薦
Industrial Motor Control Sequencing
In industrial drives, the A42MX16-2PQG160I implements PWM generation, gate-sequencing, and protection interlock logic with 125 MHz system performance, far exceeding the tens-of-kHz timing needs of motor control. The -40C to +85C industrial grade suits factory floor environments, while 5V-tolerant I/O interfaces directly with legacy drive controllers. Placed between a microcontroller and power-stage gate drivers, it offloads deterministic timing-critical tasks; the OTP configuration ensures no configuration corruption from industrial noise transients, unlike SRAM-based FPGAs.
推薦
Military and Aerospace System Upgrades
Microsemi MX FPGAs have a long heritage in defense platforms, and the A42MX16 continues that role in sustainment and upgrade programs. The antifuse architecture is immune to configuration upset and offers high design security since no bitstream is stored externally - a key advantage for avionics and defense hardware. The industrial temperature range and 0.45um CMOS process with low static power support conformal-coated, sealed enclosures. For space-constrained upgrades, the 24K gates replace arrays of legacy PAL/GAL devices in one certified device.
推薦
5V Industrial Bus Bridging
Many installed industrial systems still run 5V signaling on backplanes and field interfaces. The A42MX16-2PQG160I operates at 5V and provides 125 user I/O that directly bridge 5V buses to modern 3.3V logic, implementing bus arbitration, translation, and protocol glue inside one device. Its instant-on antifuse configuration means the bridge is active within microseconds of power application - critical in systems without controlled power sequencing. The 160-PQFP surface-mount package with 0.635mm pin pitch supports standard industrial PCB assembly.
推薦
Test and Measurement Instrumentation
The A42MX16-2PQG160I serves as timing, sequencing, and interface logic in bench and rack instrumentation. Its deterministic antifuse interconnect avoids configuration-load delay at power-up, so instruments are immediately testable, and its fixed routing yields repeatable timing - valuable for calibration stability. With 129MHz/215MHz internal toggle rates, it handles counter/timer, trigger, and data-path multiplexing functions around converters. Distributor data cites 24K gates with 608 CLBs, sufficient for a full instrument control state machine plus I/O formatting logic.
推薦
In-Cabin Automotive Telematics Interfaces
Microsemi publishes an automotive-grade MX variant for in-cabin telematics and automobile interconnect applications, and the standard A42MX16 logic design ports directly into these flows. In telematics gateways, the A42MX16-2PQG160I aggregates sensor, switch, and bus status lines into consolidated interfaces to host processors. The 5V I/O matches legacy vehicle harness levels, while the OTP configuration eliminates boot-delay and bitstream-tampering concerns in vehicles. Its 125 user I/O consolidate dozens of discrete GPIO expanders into one device, cutting wiring harness complexity.

- Industrial temperature range (對比A42MX16-2PQG160)

設計說明
The A42MX16 supports dual 3.3V/5V operation. In mixed-voltage systems, apply the 5V rail for I/O compatibility with legacy logic and observe the datasheet DS2316 sequencing and pin-assignment rules. Because antifuse MX devices have very low static power, bulk decoupling requirements are modest, but add 0.1uF ceramic bypass capacitors at each VCC/GND pin pair on the 160-PQFP to handle internal toggle current spikes at 125 MHz.
The MX family is one-time-programmable (antifuse). Never release a PCB to assembly before completing full timing simulation and pin verification in Libero; a routing change after programming requires a new device. Confirm the I and speed-grade suffix on purchasing documents - the commercial-grade A42MX16-2PQG160 (0C to +70C) is not a substitute in industrial -40C to +85C enclosures.
The 160-PQFP uses a 0.635mm (0.025 in) terminal pitch per Microchip USA product data. Use fine-pitch QFP land patterns per the datasheet package drawing, with fan-out vias on a 0.5mm grid to escape 125 signal pins. For the exposed mechanical reliability in vibration-prone industrial deployments, consider corner glue fillets and symmetric trace fan-out to reduce solder-joint stress.
At -2 speed grade toggle rates up to 215 MHz internal and 125 MHz system performance, keep high-fanout clock nets short and consider the MX global clock resources rather than general routing. Series-terminate fast 5V-switching outputs driving long cables to limit ringing, and reserve adjacent ground pins for return paths on bus interfaces.
