A42MX24-2PQG160I 개요
A field-programmable gate array (FPGA) is a semiconductor device containing a matrix of configurable logic blocks (CLBs) and programmable interconnects that designers configure after manufacturing. The MX family belongs to the antifuse FPGA category, meaning its interconnect is one-time programmable and retains configuration at power-up without an external configuration ROM - a key reliability advantage over SRAM-based FPGAs. FPGAs sit above CPLDs and below ASICs in the integration hierarchy and serve as a single-chip ASIC alternative for legacy PLD consolidation.
Key features include MultiPlex I/Os supporting mixed-voltage 5.0V and 3.3V systems, programmable PCI operation fully compliant with the PCI Local Bus Specification version 2.1, and a low-power mode. The 0.45um CMOS process delivers dependable, single-chip, high-volume operation at low cost.
The antifuse architecture provides inherent resistance to configuration upsets, making the A42MX24 well suited to industrial control, legacy system sustainment, high-reliability embedded logic, and military/defense retrofit programs where 5V compatibility is mandatory.
Designers should note that the antifuse fabric is one-time programmable, so design iteration requires new devices; plan programming yields accordingly. Verify 114.75MHz-class timing closure against the DS2136 datasheet for your speed grade.

일반적인 애플리케이션
A42MX24-2PQG160I 적합 용도: 6 애플리케이션s: Legacy 5V PLD Consolidation, Industrial Control and Automation, PCI Bus Interface Logic, Defense and Avionics Sustainment, High-Reliability Embedded Logic, ASIC Prototyping and Bridge Logic.
Legacy 5V PLD Consolidation
The A42MX24-2PQG160I is purpose-built for integrating multiple legacy 5V PLDs, PALs, and GALs into a single 36K-gate chip. Its native 5.0V architecture means no level shifters or dual-rail power trees are needed when replacing older 5V glue logic, and MultiPlex I/Os directly interface 5.0V and 3.3V domains. The antifuse fabric powers up instantly configured, matching the behavior of the ROM-less legacy devices it replaces. In sustainment programs, one A42MX24 typically replaces 5-15 TTL/PLD packages, cutting board area and failure points while preserving proven 5V system timing.

Industrial Control and Automation
In industrial controllers, motor-drive interface logic, and factory automation backplanes, the A42MX24-2PQG160I provides deterministic, one-time-programmed logic immune to configuration corruption from power glitches - a known weakness of SRAM FPGAs on noisy industrial floors. The industrial temperature rating of -40C to +85C covers unconditioned cabinets and cold-start environments. The PCI Local Bus v2.1 compliance allows direct attachment to industrial PC backplanes, and the low-power mode reduces cabinet heat. Antifuse non-volatility also removes configuration load time, so control logic is active immediately at power-up.
추천
PCI Bus Interface Logic
The A42MX24 is fully compliant with the PCI Local Bus Specification version 2.1 and offers programmable PCI I/O characteristics, making it a natural host for custom PCI interface cores in 33MHz systems. MultiPlex I/Os can be programmed for PCI-compliant drive and slew at both 5.0V and 3.3V signaling, letting one design serve both bus voltage environments. With 125 user I/Os, a single device implements the PCI state machine plus target application logic such as FIFOs and register files. Implementing PCI in antifuse fabric avoids SRAM configuration security concerns in commercial equipment.
추천
Defense and Avionics Sustainment
Legacy defense and avionics platforms standardized on the Actel MX family because antifuse FPGAs tolerate radiation-induced configuration upsets and provide instant-on, single-chip operation without boot devices. The A42MX24-2PQG160M variant (military range) shares this die for programs needing extended qualification. For depot-level sustainment of radar interfaces, mission-data encoders, and 1553 glue logic built on 5V architecture, the A42MX24-2PQG160I keeps obsolete designs manufacturable. The 0.45um process is well characterized, and design files in Libero remain compatible for re-programming new devices.

High-Reliability Embedded Logic
Applications that cannot tolerate configuration corruption - medical device control logic, test-equipment sequencers, and security systems - benefit from the one-time-programmed antifuse fabric of the A42MX24-2PQG160I. Unlike SRAM FPGAs, there is no bitstream to intercept or corrupt, providing inherent design-security and failure-mode advantages. The 36K-gate capacity handles state machines, counters, bus bridges, and custom peripherals, while 125 I/Os interface mixed 3.3V/5V subsystems. Instant power-up configuration simplifies watchdog and Brown-out recovery design, since logic is functional within microseconds of power application.
추천
ASIC Prototyping and Bridge Logic
Before committing to ASIC tape-out or while an ASIC is in fabrication, the A42MX24-2PQG160I serves as a low-cost prototyping and system-bridge device for modest gate counts. Microchip positions MX explicitly as a single-chip ASIC alternative for high-volume, cost-sensitive designs where a full ASIC is not economical. The antifuse fabric delivers ASIC-like deterministic timing without reconfiguration latency, and the 160-pin PQFP is inexpensive to assemble. Engineers can validate RTL, interface real 5V peripherals, and ship bridge logic while iterating on the target ASIC design.

- Speed grade -2 performance vs standard grade (vs A42MX24-PQG160I)
설계 노트
The A42MX24 operates from a 5V core with 3.3V/5V MultiPlex I/O banks. Decouple each VDD/GND pin pair with 0.1uF ceramic capacitors placed within 5 mm of the pin, plus bulk 10uF per rail. Mixed-voltage systems must ensure 3.3V banks are powered before 5V I/O drivers drive them, or use I/O bank grouping to respect the datasheet power-up ordering.
The antifuse fabric is one-time programmable - there is no reflow-and-retry. Budget 15-25% spare devices per programming session for yield loss, and lock your design in Libero before ordering. Also remember the -2 speed grade timing is faster than standard grade: swapping in a standard-grade A42MX24-PQG160I requires full static timing re-verification even though the footprint is identical.
Programmable PCI I/O requires attention to drive strength and slew settings on the PCI bus. When using MultiPlex I/Os at 5.0V with PCI v2.1 compliance, follow the 40MX/42MX datasheet DS2136 PCI implementation section for output timing parameters. Keep 160-PQFP lead-length stubs short on the PCI bus; series termination resistors (22-33 ohm) are typically needed on clock and high-fanout nets.
