A42MX24-1TQG176M 概要
An FPGA (Field-Programmable Gate Array) is a reconfigurable integrated circuit that implements digital logic through programmable interconnect and logic modules. Within the power management hierarchy of digital ICs, the MX family occupies the one-time-programmable (OTP) antifuse FPGA segment, offering designers a reliable single-chip ASIC alternative for integrating legacy PLDs into a single, low-cost, high-volume device.
Key features include 36K system gates, 912 logic cells, up to 150 user I/Os, and D-modules arranged around the device periphery containing wide-decode circuitry that provides a fast, wide-input AND function similar to CPLD architectures. The 5.0V-tolerant, flexible architecture makes MX an ideal platform for legacy PLD consolidation. The antifuse fabric is non-volatile and configuration-data secure, unlike SRAM FPGAs that require external configuration memory.
Technically, the 42MX family combines C-modules (combinational logic) and S-modules (sequential logic with flip-flops), with A42MX24 and A42MX36 devices adding D-modules for wide-decode functions. This module mix enables efficient state machines, decoders, and glue-logic integration at low static power.
Typical applications include legacy PLD consolidation, industrial control glue logic, military/aerospace upgrades of 5V systems, and bridge/interface logic where 5V-tolerant I/O is required.
Design consideration: as a one-time-programmable antifuse device, programming is irreversible - verify the design thoroughly in simulation with Libero/Microsemi design tools before programming production units, and ensure 3.3V/5V rail sequencing complies with the datasheet.

主な用途
A42MX24-1TQG176M の用途: 6 件s: Legacy PLD Consolidation, Industrial Control Glue Logic, Defense and Aerospace System Upgrades, 5V-Tolerant Bridge and Interface Logic, Test and Measurement Adapter Logic, ASIC Prototyping and Emulation.
Legacy PLD Consolidation
The MX family is explicitly positioned by Microchip as a single-chip ASIC alternative for integrating legacy PLDs. The A42MX24-1TQG176M provides 36K system gates with D-module wide-decode logic, allowing multiple 22V10-class PALs, GALs, and small CPLDs to be merged into one device. Because I/O is 5V-tolerant on a 3.3V/5V architecture, legacy board-level voltage domains do not require level translation. OTP antifuse programming also eliminates configuration-ROM BOM cost and configuration-time delays at power-up, a common pain point in long-lifecycle industrial boards.
おすすめ
Industrial Control Glue Logic
In industrial controllers, the A42MX24-1TQG176M implements address decoding, bus arbitration, and interface bridging between microprocessors and peripherals. The D-modules provide fast, wide-input AND functions similar to CPLD decode architectures, enabling chip-select logic with predictable single-path delays on the -1 speed grade. The 150 user I/Os in the 176-TQFP cover most 8/16-bit microprocessor buses with margin. Non-volatile antifuse configuration means the logic is active immediately at power-on with no configuration controller, improving system bring-up reliability in factory environments with unstable power sequencing.
おすすめ
Defense and Aerospace System Upgrades
Antifuse FPGAs are favored in defense upgrades because the programmed interconnect cannot be read back as bitstream data, providing inherent configuration security compared to SRAM FPGAs. The A42MX24-1TQG176M's 5V-tolerant I/O directly interfaces with legacy military 5V logic families without translators, easing retrofit of avionics and ground systems. The A ordering code variant (A42MX24-TQG176A) supports programs requiring higher screening levels. Designers should model timing on the -1 grade in Libero and reserve the TQG176A variant where environmental screening is mandated.
おすすめ
5V-Tolerant Bridge and Interface Logic
The MX 5.0V architecture lets the A42MX24-1TQG176M sit directly between legacy 5V TTL/CMOS buses and 3.3V subsystems. With 150 user I/Os and dual 3.3V/5V supplies, designers implement PCI-era bus bridges, backplane interfaces, and mixed-voltage memory controllers in one device. Unlike SRAM FPGAs, no bus-switch or series-resistor level-shifting schemes are needed at 5V boundaries. Static power is low for the 0.45um process, but designers should still budget I/O current per the DS2316 DC characteristics when driving heavily loaded 5V buses.
おすすめ
Test and Measurement Adapter Logic
Bench instruments and fixture adapters benefit from the A42MX24-1TQG176M's immediate power-on operation and fixed timing. Decode, clock division, and protocol-shunt logic programmed into antifuse fabric behaves identically across every unit, simplifying calibration compared to devices with configuration variability. The -1 speed grade provides deterministic delays suited to sub-50MHz control paths common in fixture logic. The 176-TQFP's 0.5mm pitch supports straightforward rework and socketed prototyping fixtures used in production test engineering.
おすすめ
ASIC Prototyping and Emulation
Before committing to an ASIC mask set, the A42MX24-1TQG176M can prototype control-path and glue logic at 36K gates. Although antifuse devices are OTP, the low unit cost of the MX family allows multiple programming iterations during bring-up, and the deterministic antifuse timing closely models ASIC static timing without SRAM-FPGA reconfiguration artifacts. The 5V-tolerant I/O matches the voltage domains of many mature-node ASIC test benches. Combine with the A42MX36 for designs that outgrow 36K gates during emulation.

設計ノート
The A42MX24 uses dual 3.3V/5V supplies. Follow the DS2316 power-up requirements: decouple each VDD/VCCI pin with 0.1uF ceramic capacitors placed within 2mm of the pin, plus bulk 10uF per rail. Verify rail sequencing per the datasheet to avoid latch-up on the 0.45um process. Budget static and I/O current using the DS2316 DC tables; the 150 user I/Os driving 5V TTL loads can dominate total power in bus-heavy designs.
This is a one-time-programmable antifuse FPGA - programmed devices cannot be erased or reprogrammed. Complete functional simulation and timing analysis in Libero SoC before submitting devices to programming, and order engineering samples in low quantities before volume programming. Reserve the -1 speed grade timing margin of at least 10% in static timing analysis, as antifuse routing delays are deterministic but not adjustable after programming.
The 176-TQFP has 0.5mm pitch leads; use a 4-mil trace/space land pattern per IPC-7351 TQFP-176 conventions and include thermal relief vias under the center for inspection access. Keep high-fanout D-module decode outputs on short, direct traces to minimize stub reflections. Unused I/O should be configured per DS2316 recommendations (tri-state with weak pull-up or ground) to prevent floating-node EMI.
