A42MX24-PQG160A 概述
An FPGA (Field Programmable Gate Array) is a semiconductor device containing a matrix of configurable logic blocks and programmable interconnects that the designer programs to implement custom digital logic. Within the hierarchy of programmable logic, FPGAs sit above CPLDs in density and flexibility, and the MX family specifically serves as a single-chip ASIC alternative: the 42MX devices integrate legacy PLD, glue-logic, and control functions into one low-cost, high-volume 0.45 um process device.
Key features of the A42MX24 include 36K system gates with 912 logic cells, a flexible 5.0V-tolerant architecture that simplifies integration with legacy 5V systems, 125 user I/O, and industrial-plus temperature range suitable for automotive and harsh-environment deployments. The device is ROHS3 compliant and lead free, easing transition of mature 5V designs to current environmental standards.
Architecturally, the MX family combines combinatorial and sequential logic modules with embedded routing resources, delivering deterministic performance of up to 135 MHz - adequate for legacy control, interface bridging, and state-machine applications. As a one-time or low-volume programmable platform, it eliminates NRE costs of full-custom ASICs while shortening the design and development cycle.
Typical applications include legacy PLD consolidation, industrial control systems, 5V bus interfacing, automotive modules requiring -40C to +125C operation, and ASIC prototyping for the MX/AX architecture migration path.
When designing with the A42MX24-PQG160A, respect the two-rail supply requirement (3V-3.6V core/I-O domain and 4.5V-5.5V domain) and follow the Microchip/Microsemi MX datasheet power-up sequencing and decoupling recommendations. Note the 10-week manufacturer lead time when planning production buys.

典型应用
A42MX24-PQG160A 适用于 6 应用s: Legacy PLD Consolidation, 5V Industrial Control Systems, Automotive Electronic Modules, ASIC Prototyping and Bridge Logic, Bus Interface and Protocol Translation, Test and Measurement Fixtures.
Legacy PLD Consolidation
The A42MX24-PQG160A's 36K gates and 912 logic cells let designers fold dozens of legacy PAL/GAL/22V10 devices into one chip, cutting board area and BOM count. Its flexible 5.0V-tolerant MX architecture directly accepts legacy 5V TTL/CMOS signaling on the 125 user I/O, eliminating level-shifting circuitry. Per Microchip, MX is explicitly positioned as a single-chip ASIC alternative for integrating legacy PLDs at low cost in high-volume production.
推荐
5V Industrial Control Systems
Industrial PLC backplanes and motor-control boards still run 5V logic, and the A42MX24-PQG160A's dual-rail operation (3V-3.6V and 4.5V-5.5V) plus 5V-tolerant I/O makes it a natural fit. Its 135 MHz system speed covers sequencers, bus arbitration, and interlock logic, while -40C to +125C operation survives cabinet and floor environments. Deterministic FPGA timing avoids software latency of MCU-based glue logic in safety interlocks.
推荐
Automotive Electronic Modules
Listed as an automotive-grade MX device, the A42MX24-PQG160A operates from -40C to +125C, covering underhood-adjacent and body-electronics zones. It implements seat/door module sequencing, lamp diagnostics, and sensor-interface glue logic with 125 flexible I/O. The 0.45 um mature process offers stable long-term supply for programs spanning a decade, and the ROHS3-compliant A-suffix package meets current automotive environmental directives.
推荐
ASIC Prototyping and Bridge Logic
Before committing to an ASIC, engineers validate RTL on the A42MX24's 36K gates; the MX architecture is the direct predecessor platform for Microsemi Axcelerator/ProASIC migration paths. Its 912 cells and 135 MHz performance suffice for peripheral controllers, bus bridges, and protocol translators. The 160-PQFP 28x28 mm package is hand-solderable on prototype boards, and tray packaging suits low-volume lab builds without reel commitments.
推荐
Bus Interface and Protocol Translation
With 125 user I/O and 135 MHz toggle capability, the A42MX24-PQG160A bridges ISA/VME-style parallel buses, parallel peripherals, and custom serializers to modern controllers. The 5V-tolerant MX I/O accepts direct legacy signaling, while the FPGA fabric implements state machines for handshaking, wait-state generation, and byte-lane steering. Its deterministic single-chip solution removes the timing-skew risks of multi-chip PLD chains.
推荐
Test and Measurement Fixtures
Production test equipment often needs custom timing generators, pattern muxes, and pass/fail comparators; the A42MX24's 36K gates implement these in one 28x28 mm PQFP running up to 135 MHz. The -40C to +125C range suits thermally stressed rack environments, and the deterministic FPGA fabric delivers repeatable stimulus timing that software-driven testers cannot match. 125 I/O covers wide parallel bus poke/probe applications.

关键差异点
- 4x the logic capacity of smaller same-footprint MX parts （对比 A42MX09-PQG160A)
- Full automotive temperature range （对比 A42MX09-3PQG160I)
- 5V-tolerant dual-rail architecture （对比 Cross-brand modern FPGAs (Xilinx/Altera))
设计说明
The A42MX24-PQG160A requires two supply domains: 3V-3.6V and 4.5V-5.5V. Implement each rail with local 0.1 uF ceramic decoupling per supply pin pair plus 10 uF bulk per rail. Follow the MX datasheet power-up sequence to avoid latch-up on the 5V-tolerant I/O structure. Verify worst-case core current against the datasheet supply-current tables at 135 MHz toggle rates before sizing the 3.3V regulator.
The 160-PQFP 28x28 mm package has 0.65 mm-pitch leads requiring careful solder-paste stencil design; use NSMD pads per IPC guidance found in the Microchip packaging data. Reserve keep-out clearance for lead forming and inspection. Unused user I/O should be programmed to a defined state (input with pull or grounded output) per MX design guidelines to prevent floating-node EMI.
Do not confuse the A-suffix (RoHS3 lead-free) part with legacy leaded A42MX24-PQG160 in mixed stock - they are not drop-in equivalent for RoHS-restricted builds. Also confirm the 10-week manufacturer lead time in production plans, and verify logic capacity in Libero/MX tools before migrating smaller A42MX09 designs up to the 36K device, since routing congestion affects achievable gate utilization.
