A42MX24-2PLG84I - 36K Gate Antifuse FPGA, 84-PLCC | Microchip
MPN: A42MX24-2PLG84I ✓ فعالA42MX24-2PLG84I جائزہ
An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC that implements custom digital circuits after manufacturing. Unlike SRAM FPGAs, the MX family uses one-time-programmable antifuse interconnects, which makes it a reliable, single-chip ASIC alternative: the configuration is retained permanently, requires no external boot flash, is immune to configuration readback attacks, and powers up instantly with no configuration time. Within the programmable logic hierarchy, the MX family sits as a mature, low-cost, high-volume platform ideal for integrating legacy PLD and glue-logic designs into a single device.
Key features include 36K system gates with 912 logic cells, dedicated D-modules arranged around the device periphery that provide fast, wide-input decode functions similar to CPLD architectures, and flexible 3.3V/5V I/O operation for legacy 5V bus interfacing. The 84-PLCC package is through-hole-compatible for socketed use and easy to rework, making it popular for defense, industrial, and long-lifecycle systems.
The antifuse fabric architecture delivers deterministic interconnect delays and low static power, while the S-module and C-module combination enables both combinational and sequential logic efficiently. Typical applications include legacy PLD consolidation, industrial control, military/defense subsystems, telecommunications line cards, and 5V-tolerant bus bridging in mixed-voltage systems.
Design consideration: because MX devices are one-time-programmable, always complete functional simulation in Libero SoC before programming, and reserve the -2 speed grade timing margin for worst-case industrial temperature operation. Pricing below is as of 2026-08-30.

عام استعمالات
A42MX24-2PLG84I کے لیے موزوں ہے 6 ایپلیکیشنs: Legacy PLD / Glue Logic Consolidation, Defense and Avionics Subsystems, Industrial Control and Automation, Mixed 3.3V/5V Bus Bridging, Telecommunications Line Cards, Test and Measurement Fixtures.
Legacy PLD / Glue Logic Consolidation
The A42MX24-2PLG84I is purpose-built by Microchip as a single-chip ASIC alternative for integrating legacy PLDs, PALs, and glue logic into one low-cost device. Its 36,000 gates and 912 cells absorb multiple 22V10-class devices, while D-modules provide fast wide-input decode functions similar to CPLD architectures - ideal for address decoding and bus control. The 84-PLCC package simplifies replacement of socketed legacy parts, and one-time-programmable antifuse fabric removes the boot-flash BOM line entirely.

Defense and Avionics Subsystems
Antifuse FPGAs are favored in defense and aerospace programs because the configuration cannot be read back, survives radiation-tolerant system profiles, and powers up instantly with no configuration device to fail. The A42MX24-2PLG84I's industrial -40C to +85C rating, deterministic interconnect delays, and mature 0.45um process with long-lifecycle availability make it suitable for interface control, bus bridging, and sequencer logic in avionics LRUs and ground systems. The 84-PLCC J-lead package also eases rework in low-volume programs.

Industrial Control and Automation
In industrial controllers and motor-drive interface boards, the A42MX24-2PLG84I provides 5.0V-tolerant I/O that connects directly to legacy PLC backplanes and sensor buses without level shifters. The 72 user I/O and wide-decode D-modules implement address decoding, interlock logic, and I/O expansion with microsecond-deterministic response. Its antifuse fabric retains configuration through brownouts and power cycles - important in factory environments - while the industrial temperature rating covers uncontrolled cabinet conditions from -40C to +85C.

Mixed 3.3V/5V Bus Bridging
The MX family's mixed-voltage I/O makes the A42MX24-2PLG84I an effective bridge between 5V TTL/CMOS systems and 3.3V subsystems. Designers frequently use it to interface modern 3.3V microcontrollers to 5V ISA-style, VME, or proprietary backplanes. With 72 I/O supporting both 3.3V and 5.0V signaling in a single 84-PLCC device, it replaces banks of level-shifting transceivers, cutting BOM cost and board area. Deterministic antifuse routing also keeps bus setup/hold timing stable across production lots.

Telecommunications Line Cards
Legacy telecom line cards and backplane adapters rely on the A42MX24-2PLG84I for framing-glue, control-plane decode, and LED/relay drive sequencing. Its instant-on antifuse configuration means line cards are active the moment power is applied - no configuration delay that would trip backplane hot-swap supervisors. The 36K-gate capacity covers T1/E1 glue logic and alarm aggregation, and the PLCC package supports the rework-heavy provisioning workflows typical of NEBS-style equipment maintenance.

Test and Measurement Fixtures
Prototype and production test fixtures benefit from the A42MX24-2PLG84I's combination of socket-friendly 84-PLCC packaging, instant power-up, and fixed timing. Fixtures use its 72 I/O and D-module decoders to implement address generators, stimulus sequencers, and pass/fail combinational monitors. Because antifuse programming is permanent, a validated fixture configuration is bit-reproducible across every programmed unit - an advantage over SRAM FPGAs where bitstream or configuration-flash variation can alter fixture timing between builds.

ڈیزائن نوٹس
The A42MX24-2PLG84I is one-time programmable. Complete behavioral simulation, synthesis, and static timing analysis (industrial corner, speed grade -2) in Microchip Libero SoC BEFORE programming, and use a socketed device for first-article bring-up. Programmed antifuses cannot be erased, so an unverified bitstream means a scrapped device.
The MX family uses a 5.0V architecture with 3.3V/5.0V mixed I/O. Provide clean 5V to the core/VCI pins and decouple each supply pin with 0.1uF ceramic plus 10uF bulk capacitance. Verify which pins are reserved for programming voltages (VPP/VCI) in the datasheet PLCC84 table and never drive them during normal operation - doing so can corrupt the device.
The 84-PLCC J-lead package has ~1.27mm lead pitch with leads on all four sides. Keep clock traces short to dedicated CLK pins, use a solid ground plane, and place 0.1uF decoupling inside the PLCC footprint. PLCC sockets add contact reliability concerns in vibration environments - prefer direct soldering for shock/vibration applications.
With 0.45um antifuse technology and 912 cells, static power is low and no heatsink is needed for typical glue-logic utilization. Still, verify junction temperature with theta_JA for PLCC-84 (approx. [DATA_NEEDED: theta_JA value]) if driving many 5V outputs at high toggle rates, since 5V I/O switching dominates power in MX designs.
