MPN: A42MX36-1BGG272 ✓ Hoạt độngA42MX36-1BGG272 Tóm tắt
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that designers configure after manufacturing. Within the programmable logic hierarchy, the MX family sits as a one-time-programmable antifuse FPGA - a single-chip ASIC alternative - under the broader category of programmable logic devices (PLDs), which also includes CPLDs and PLDs.
Key features include Microchip's reliable antifuse architecture operating at 5.0V, which provides non-volatile, tamper-resistant configuration that is live at power-up with no external configuration PROM required. This makes MX devices ideal for integrating legacy PLD designs, glue logic, and bus interfaces into a single low-cost, high-volume device. The 272-ball BGA (JESD-30 BBGA) package provides high I/O density in a surface-mount footprint.
The A42MX36 is the largest member of the 42MX family. It uses a CMOS process with a flexible routing fabric suited to state machines, address decoding, bus interfacing, and control logic. Design entry and programming use the Microchip (Microsemi) Libero SoC design suite.
Typical applications include legacy ASIC/PLD consolidation, industrial control, military and aerospace systems (ceramic CQ208/CQ256 versions are screened to MIL-STD-883 levels), telecommunications line cards, and embedded system glue logic.
Design consideration: the 5.0V core/I-O architecture requires a 5V power rail; verify I/O voltage compatibility with adjacent modern 3.3V or 2.5V devices and use appropriate level shifting or series resistors on mixed-voltage busses.

Ứng dụng tiêu biểu
A42MX36-1BGG272 phù hợp cho 6 Áp dụngs: Legacy PLD and ASIC Consolidation, Industrial Control and Automation, Military and Aerospace Systems, Telecommunications Line Cards, Test and Measurement Equipment, Embedded System Glue Logic.
Legacy PLD and ASIC Consolidation
The A42MX36-1BGG272 consolidates multiple legacy PLDs, glue logic, and small ASICs into a single 54,000-gate antifuse device. Its 1184 CLBs and 2438 logic cells absorb address decoders, state machines, and bus logic, while the non-volatile antifuse fabric is live at power-up, matching the behavior of the original discrete devices. The 202 user I/Os on the 272-BGA footprint support wide legacy bus widths at 5.0V CMOS levels, eliminating level-shifting circuitry in older system architectures.
Được đề xuất
Industrial Control and Automation
In industrial controllers, the A42MX36-1BGG272 provides deterministic, single-chip logic with the -1 speed grade supporting up to 83 MHz system clocks, adequate for motor sequencing, interlock logic, and I/O scanning. The 5.0V architecture directly interfaces with legacy industrial sensors and actuators running 5V CMOS levels, and antifuse configuration survives power interruptions without reconfiguration time. The 2560 RAM bits support small FIFOs and lookup tables used in sequencing and monitoring functions.

Military and Aerospace Systems
The MX family is a proven platform in defense electronics: the largest member A42MX36 is available in CQ208 and CQ256 ceramic packages screened to MIL-STD-883 levels, per the Microchip 40MX/42MX datasheet. The plastic 272-BGA A42MX36-1BGG272 supports ground-based and benign-environment military equipment, offering single-event-immune non-volatile configuration with no configuration readout path, reducing the attack and upset surface compared to SRAM FPGAs in secure systems.

Telecommunications Line Cards
Telecom line cards use the A42MX36-1BGG272 for framing control, backplane interface glue logic, and alarm aggregation at line rates within the 83 MHz envelope of the -1 grade. The 202 configurable I/Os terminate wide TDM backplane busses at 5.0V levels, and the antifuse fabric provides deterministic timing with no configuration latency at card power-up, simplifying hot-swap sequencing and fault recovery designs in central-office equipment.
Được đề xuất
Test and Measurement Equipment
Bench and automated test instruments use the A42MX36-1BGG272 as programmable control fabric for stimulus routing, relay matrix control, and counter/timer logic. The 54,000-gate capacity with 2560 RAM bits implements timing generators and capture buffers, while 202 I/Os address large relay and multiplexer arrays. One-time-programmable configuration guarantees an instrument always powers up with the factory logic image, an advantage for calibration integrity.
Được đề xuất
Embedded System Glue Logic
Microprocessor-based embedded systems deploy the A42MX36-1BGG272 to glue a legacy CPU to memory, peripherals, and custom ASICs: address decoding, wait-state generation, interrupt aggregation, and bus-width conversion all fit within the 2438-cell fabric. The 5.0V I/O rings connect directly to 5V microprocessors such as older 80C51 and 68K family parts, and the 272-BGA gives routing flexibility with abundant spare balls for power and ground.

Ghi chú thiết kế
The MX family operates from a single 5.0V rail. Decouple the 272-BGA power and ground balls with an array of 0.1 uF ceramic capacitors placed directly under the BGA footprint, plus bulk 10 uF capacitance near the regulator. Verify the 5V rail tolerance against the datasheet operating conditions before production; brownout during antifuse-device operation does not corrupt configuration, but out-of-spec voltage degrades AC timing.
The 5.0V CMOS I/O rings driving 202 outputs at 83 MHz can generate significant ground bounce. Maximize the number of balls assigned to ground in your pin assignment, keep switching outputs grouped away from sensitive inputs, and add series termination (22-33 ohm) on fast outgoing edges. Because the device is one-time-programmable, complete full timing simulation in Libero SoC before committing the design to silicon.
Antifuse FPGAs cannot be reprogrammed - a design change requires a new physical device. Prototype using the same BG272 package, exhaustively verify the design in Libero SoC simulation and timing analysis, and hold a programming-slot review before committing production devices. Also note that when converting from PQ208 to BG272 or ceramic CQ packages, consult the family datasheet pinout tables; PQ208 and CQ208 are pin-compatible, but BG272 requires its own layout.
