A42MX24-1PQG208M Descripción general
An FPGA (Field Programmable Gate Array) is a semiconductor device containing a fabric of programmable logic blocks and interconnects that engineers configure in the field, unlike fixed-function ASICs. Within the programmable logic hierarchy, the MX family sits as a low-cost, high-volume, antifuse-based one-time-programmable platform, positioned as a reliable single-chip ASIC alternative and a consolidation target for legacy PLDs and glue logic.
Key features include 36K system gates in a 0.45um CMOS process, a flexible dual 3.3V/5V supply architecture that directly interfaces with legacy 5V systems, and D-modules arranged around the device periphery that provide wide-decode AND functionality comparable to CPLD and PAL architectures, with programmable output inversion for active-HIGH or active-LOW assertion. The 208-pin PQFP provides 176 user I/O, ample pin count for bus interfacing, and surface-mount assembly compatibility.
Architecturally, the 42MX fabric combines C-modules (combinational), S-modules (sequential with flip-flops), and D-modules (wide decode). The D-module arrangement gives A42MX24 fast address decoding and wide-input combinational functions at speeds approaching dedicated CPLDs, a differentiator versus fine-grained FPGA fabrics. The antifuse programmable interconnect is non-volatile, immune to configuration bitstream loading at power-up, and inherently more secure against readback than SRAM FPGAs.
Typical applications include legacy system redesign where 5V I/O compatibility is mandatory, automotive electronic control modules requiring the M-grade screening, industrial motor controllers, and high-volume products replacing masked ASICs where NRE cost is prohibitive. The device integrates multiple discrete PLDs into one low-cost package, reducing board area and BOM count.
Design consideration: the MX family is one-time programmable (antifuse), so prototype your design thoroughly in the Libero/Synplify flow before committing; there is no reprogramming. Verify 5V-tolerant I/O assignments against the 42MX datasheet current and slew limits, and plan power decoupling for the 3.3V/5V dual-rail domains.

Aplicaciones típicas
A42MX24-1PQG208M es adecuado para 6 aplicacións: Automotive Control Modules, Legacy 5V System Redesign, ASIC Replacement in High-Volume Products, Industrial Motor and Process Control, Test and Measurement Fixtures, Aerospace and Defense Legacy Sustainment.
Automotive Control Modules
The M suffix on A42MX24-1PQG208M denotes Microchip's automotive screening, making it suitable for electronic control units requiring proven reliability. Its 5.0V-tolerant 3.3V/5V architecture interfaces directly with legacy 5V automotive sensors and actuators without level translators, while the antifuse fabric powers up instantly with no configuration bitstream load, an important attribute for modules with strict ignition timing requirements. The 176 user I/O accommodate motor control, solenoid driving, and sensor aggregation logic in a single 208-PQFP, replacing multiple discrete PLDs.
Recomendado
Legacy 5V System Redesign
Many industrial platforms still run 5V buses that modern SRAM FPGAs cannot directly interface. The MX family's efficient, flexible 5.0V architecture accepts 5V I/O, letting engineers replace obsolete PAL, GAL, and CPLD glue logic with one A42MX24 while preserving the existing 5V backplane. Its 36K gates and 912 cells consolidate multiple legacy PLDs, and D-modules provide the wide-input AND decode functions these older designs rely on at CPLD-comparable speeds, per the 42MX datasheet.
Recomendado
ASIC Replacement in High-Volume Products
Microchip markets MX as a reliable single-chip ASIC alternative for high-volume production. When ASIC NRE and mask costs are unjustified at moderate volumes, the A42MX24 provides one-time-programmable, non-volatile logic at commodity cost with no configuration device required. The antifuse fabric also avoids SRAM readback security concerns, making it attractive for proprietary designs. The 0.45um process and 36K gates suit cost-sensitive products shipping tens of thousands of units annually.
Recomendado
Industrial Motor and Process Control
The A42MX24's D-module wide-decode structure delivers fast address decoding and control-state logic suited to motor controllers, PLC I/O cards, and process instrumentation. Operating from 3.3V/5V rails, it bridges modern 3.3V microcontroller peripherals to 5V industrial field signals. Deterministic antifuse routing and instant-on operation eliminate configuration latency in safety-related interlocks, and the wide 176-I/O count supports parallel encoder, relay, and sensor interfaces on one 208-PQFP device.
Recomendado
Test and Measurement Fixtures
Production test fixtures and board-level debug equipment benefit from the A42MX24's instant-on antifuse fabric: no configuration download delays test throughput. The 5V-tolerant I/O probes and drives legacy 5V boards directly, and one-time programming prevents accidental or malicious design extraction in shared lab environments. With 176 I/O in the 208-PQFP, it terminates wide parallel buses, generates test patterns, and performs pass/fail decode logic at deterministic speeds.
Recomendado
Aerospace and Defense Legacy Sustainment
The 42MX family's long availability record, non-volatile antifuse technology, and SEU-immune one-time-programmed configuration make it a candidate for sustaining mature defense and aerospace platforms that standardized on Actel MX devices decades ago. Where designs originally used A42MX24 devices, the PQG208 variants provide form-fit-function refresh without redesign. Confirm screening level (standard vs. M/automotive) and program-specific qualification requirements before substitution in regulated programs.

Diferenciadores clave
- 5.0V-tolerant I/O architecture (frente a Xilinx Spartan / Intel Cyclone SRAM FPGAs)
- CPLD-like wide-decode D-modules (frente a A42MX16 (no D-modules at this scale))
- Instant-on non-volatile antifuse fabric (frente a A42MX36-PQG208I (same technology) vs any SRAM FPGA)
Notas de diseño
The A42MX24 operates from dual 3.3V/5V domains. Decouple each VCC pin pair with 0.1uF ceramic capacitors placed within 2mm of the pin, plus bulk 10uF per rail. Per the 42MX datasheet, 5V-tolerant I/O banks must have their associated supply present before 5V signals are applied to avoid latch-up; sequence supplies accordingly in mixed-voltage boards.
The MX family is antifuse, one-time programmable. There is no rework path after programming: a logic bug scraps the device. Fully validate timing and functional simulation in the Libero SoC design flow, and reserve JTAG/programming access on the PCB for production programming. Never treat MX prototypes like reprogrammable SRAM FPGAs during debug iterations.
The 208-PQFP (0.5mm pitch) requires careful solder-paste stencil design; use 0.10-0.12mm laser-cut stencils to prevent bridging on fine-pitch leads. Provide fiducials on two diagonal corners and keep thermal relief on GND plane connections to aid rework. Follow IPC-7351 land pattern recommendations for PQFP-208 and inspect with AXI or 100% optical inspection.
