A42MX24-PQG160M 개요
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing an array of programmable logic blocks and reconfigurable interconnects that the designer wires together to implement custom digital hardware. Within the product hierarchy, the A42MX24 belongs to the FPGA category under programmable logic ICs, positioned as a single-chip ASIC alternative for high-volume systems and legacy PLD integration.
Key features include Microsemi's proven 0.45 um antifuse technology, which produces a one-time-programmable, non-volatile configuration that is inherently immune to configuration readback attacks and radiation-induced configuration upset. The device operates from a 5.0V supply with 3.3V-tolerant multiPlex I/O support, enabling mixed-voltage system designs. D-modules arranged around the die periphery provide wide-decode functions comparable to CPLD and PAL architectures, and a low-power mode reduces static consumption in standby.
The architecture combines C-modules (8-input combinational logic), S-modules (sequential flip-flop logic), and D-modules (wide-decode), giving designers flexible mapping of state machines, decoders, and glue logic. Because the antifuse fabric is programmed permanently, there is no configuration PROM required at power-up, reducing bill-of-materials cost and boot time versus SRAM FPGAs.
Typical applications include industrial control, automotive subsystems (the M-suffix automotive grade), communications bridging, bus interfacing including programmable PCI, and consolidation of legacy 5V PLD/CPLD designs into one low-cost device.
Design consideration: the 5.0V core supply is mandatory; designers must respect the 114.75 MHz frequency ceiling and verify I/O voltage levels for 3.3V interfacing using the multiPlex I/O configuration options.

일반적인 애플리케이션
A42MX24-PQG160M 적합 용도: 6 애플리케이션s: Automotive Control Modules, Legacy 5V PLD Consolidation, Industrial Control and Automation, Communications and Bus Bridging, Test and Measurement Fixtures, Secure and Radiation-Tolerant System Logic.
Automotive Control Modules
The A42MX24-PQG160M carries the M automotive suffix and is documented in Microchip's 40MX/42MX Automotive FPGA Families datasheet (DS0025), making it a qualified choice for body control, powertrain-adjacent glue logic, and sensor-interface modules. Its antifuse fabric is non-volatile and instantly active at power-up with no configuration device, eliminating boot-time faults that SRAM FPGAs can exhibit in crank-cycle conditions. The 5.0V-tolerant multiPlex I/O system interfaces directly with legacy 5V automotive sensors while also supporting 3.3V logic. Designers typically use the 912 CLBs for state machines, PWM generation, and diagnostic counters, exploiting D-modules for fast wide-input decode of fault conditions at speeds comparable to CPLD architectures.
추천
Legacy 5V PLD Consolidation
The MX family was explicitly designed as a single-chip ASIC alternative for integrating legacy PLDs, PALs, and CPLDs on aging 5.0V boards, and the A42MX24-PQG160M is the 36K-gate point for that task. Its 5.0V core and I/O tolerance mean multiple TTL-bus interfaced devices can be absorbed without level-shifting, and the D-module wide-decode circuitry replicates the fast, wide AND functions of PAL architectures, so decode maps port with minimal timing penalty. Because the antifuse configuration is permanent, replacement parts behave identically to the programmed original from the first clock edge. Teams consolidating obsolescent 22V10, GAL, or small CPLD clusters typically map the design in Libero SoC and reach the 912-CLB budget with headroom for future changes.
추천
Industrial Control and Automation
Industrial controllers benefit from the A42MX24-PQG160M's combination of 125 user I/Os, 114.75 MHz toggle capability, and one-time-programmable determinism - there is no configuration-load latency or readback path, which simplifies functional-safety arguments in factory equipment. The 5.0V architecture directly drives optocoupler inputs and legacy PLC backplane signals, while 3.3V-capable multiPlex I/O banks bridge to modern microcontrollers on the same board. Typical roles include encoder processing, axis interlock logic, backplane bus arbitration, and watchdog/fail-safe decoding implemented in D-modules for microsecond-class response. The low-power mode reduces static draw during standby states demanded by energy-efficiency standards. Tray packaging suits mid-volume panel-builder procurement, and same-footprint speed-grade variants allow a single PCB to serve multiple product tiers.
추천
Communications and Bus Bridging
The MX family's multiPlex I/O support includes programmable PCI functionality, positioning the A42MX24-PQG160M for bus-interface and protocol-bridging duties in industrial networking and telecom backplanes. Designers implement PCI target logic, dual-port FIFO structures, and address decoding in the 912-CLB fabric, with D-modules providing the wide, fast comparators that address decoders require. The 3.3V/5.0V mixed-voltage I/O lets one device bridge legacy 5V backplanes to modern 3.3V PHYs and microprocessors without external translators. Because configuration is antifuse-based, the bridge logic is fixed and tamper-resistant at every power cycle - valuable in deployed network equipment. The 114.75 MHz maximum toggle frequency comfortably covers PCI-class clock rates and common serial-interface oversampling tasks in this device class.
추천
Test and Measurement Fixtures
Production test fixtures and bench instrumentation frequently adopt the A42MX24-PQG160M because its permanent antifuse configuration guarantees that the test vectors applied today behave identically to those applied last year - no firmware drift between calibration cycles. The 125 I/Os drive relay banks, comparators, and boundary-scan chains, while the 912 CLBs implement pattern generators, frequency dividers, and pass/fail combinatorial evaluation using D-module wide-decode for rapid multi-signal fault gating. Its 5.0V I/O tolerance matches older instrument buses, and 3.3V banks connect to USB or Ethernet companion controllers. The 160-pin PQFP is hand-assemblable in low-volume fixture shops with standard hot-air tools, and tray packaging suits the make-to-order nature of test equipment builds.
추천
Secure and Radiation-Tolerant System Logic
Antifuse FPGAs are favored where the design must not be readable or accidentally reconfigured: the A42MX24-PQG160M stores its bitstream as physical antifuse connections with no readback mechanism and no volatile configuration to upset at power-up. Security-focused industrial, defense-adjacent, and infrastructure equipment use it for key-management glue logic, secure boot sequencing support, and tamper-evident interconnect that SRAM FPGAs cannot match without external protection. Microsemi heritage in high-reliability markets means the MX fabric has long field history in such roles. Engineers pair it with a discreet MCU supervising the overall secure state machine; the FPGA enforces hardwired interlocks at 114.75 MHz-class response times while remaining entirely passive on any configuration bus at power-on.

설계 노트
The A42MX24 requires a regulated 5.0V core/I/O supply; the multiPlex I/O structure supports 3.3V signaling on designated banks, but the 5V rail quality directly affects timing. Budget a low-ESR bulk capacitor plus 0.1 uF ceramic decoupling at each VCC pin pair of the 160-PQFP. Because MX static current is modest but dynamic current scales with clock utilization, run Microchip's power estimator on your Libero netlist rather than copying datasheet typicals. Estimated: at 40 MHz with 60 percent utilization, expect tens of milliamps - verify against your design.
Antifuse devices are one-time programmable: a design change means a new physical part, so freeze timing constraints and pin assignments before committing programming files, and order pre-programmed inventory only after design sign-off. Do not confuse suffixes - PQG160M (automotive M), PQG160I (industrial), and PQG160A differ in qualification documentation and price even though the package is identical. Finally, respect the 114.75 MHz frequency ceiling: paths timed at 100 MHz+ in faster speed grades may fail on the standard grade. Simulate timing in Libero for your exact speed suffix.
The 160-pin PQFP has 0.65 mm-class gull-wing leads; use a solder-mask-defined footprint per IPC-era PQFP conventions with generous fillets, and keep trace stubs short on high-speed I/O. A solid ground plane under the die improves signal integrity and thermal relief - the exposed-lead PQFP dissipates through the leads, so adding thermal vias near corner power pins helps. For hand rework, hot-air at controlled temperature avoids lead lifting on this mature package. Assign unused I/O per datasheet recommendations to avoid floating-node noise.
