A42MX16-2VQG100 Visão geral
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs) and programmable interconnects that designers configure after manufacturing. The MX family is a member of the broader PLD hierarchy (programmable logic device -> FPGA -> configurable logic), positioned by Microchip as a reliable, single-chip ASIC alternative for legacy designs.
Key features include 608 configurable logic blocks (1,232 logic cells), an efficient 5.0V-tolerant architecture, and Actel's antifuse-based one-time-programmable technology, which gives higher design security and no configuration-load time compared with SRAM FPGAs. The -2 speed grade balances performance and cost, and the commercial temperature range suits cost-sensitive applications.
The MX architecture combines Combinatorial Modules (CMs) and Sequential Modules (SMs) within its CLBs, connected via a segmented routing fabric. Because configuration is non-volatile and internal, no external boot PROM is required, reducing BOM count and improving power-up security.
Typical applications include glue-logic consolidation, legacy PLD integration, industrial control, and bridge logic in 5V legacy systems where a single low-cost device replaces multiple SSI/MSI parts.
Design consideration: the MX family is one-time-programmable, so reserve spare logic in your design for ECOs, and verify I/O assignments against the 100-TQFP pinout before programming, as antifuse devices cannot be reprogrammed.

Configuração de pinos do A42MX16-2VQG100
| Pino 1-100 | User I/O / CLIP / VDD / GND / VPP — 83 user I/O distributed around the 100-TQFP perimeter plus dedicated power, ground, and programming-voltage pins. Exact per-pin assignment must be taken from the MX family datasheet pin table for the 100-pin VQFP package; pin functions are software-assigned via the Microchip (Actel) Designer toolchain. |
Aplicações típicas
A42MX16-2VQG100 é adequado para 6 aplicaçãos: Legacy PLD Integration, Industrial Control and Automation, ASIC Prototyping and Bridge Logic, Test and Measurement Equipment, Defense and Avionics Legacy Sustainment, Telecom and Networking Line-Card Glue Logic.
Legacy PLD Integration
The MX family's core mission is consolidating multiple legacy 5V PLDs (PALs, GALs, 22V10 devices) into a single 24K-gate device. The A42MX16-2VQG100's 5.0V-tolerant I/O and 83 user pins interface directly with legacy 5V buses without level shifters, while its antifuse configuration is permanent at power-up - no configuration device or boot time. In a typical retrofit board, 10-20 SSI/MSI/PLD packages collapse into one 100-TQFP, cutting BOM count, assembly cost, and failure points while preserving the original logic functionality.
Recomendado
Industrial Control and Automation
In industrial controllers, the A42MX16-2VQG100 implements state machines, interlock logic, and I/O expansion at up to 117 MHz toggle rates - far above PLC scan needs - while its one-time-programmable antifuse fabric resists configuration corruption from electrical noise, a known failure mode of SRAM FPGAs in electrically harsh factory environments. The commercial-grade 100-TQFP suits enclosed controllers; for extended -40C to +85C ambient use, the pin-identical A42MX16-2VQG100I drops into the same footprint with no redesign.
Recomendado
ASIC Prototyping and Bridge Logic
The MX family is explicitly marketed by Microchip as a single-chip ASIC alternative for medium-volume production. Designers use the A42MX16-2VQG100 to bridge incompatible buses (e.g., a legacy 5V peripheral to a 3.3V processor), implementing address decoding, wait-state generation, and byte-lane steering in the 608-CLB fabric. Because the antifuse configuration is non-volatile and write-once, deployed bridge logic cannot be read out or altered, providing IP protection that SRAM-based FPGAs cannot match at this price point.
Recomendado
Test and Measurement Equipment
Bench instruments and ATE fixture logic benefit from the A42MX16-2VQG100's deterministic, instant-on behavior: antifuse configuration means the device is functional at power application with zero configuration latency, simplifying power-sequencing design. The 83 I/O pins drive fixture relays, mux select lines, and status monitoring, while the 117 MHz capability handles counter/timer functions. Reference Microchip's MX family datasheet for AC timing tables when constraining fixture timing budgets in the -2 grade.
Recomendado
Defense and Avionics Legacy Sustainment
Many defense platforms standardized on Actel MX devices during the 1990s and 2000s. For obsolescence-driven redesigns, the A42MX16-2VQG100 and its graded siblings keep the same 100-TQFP footprint: A42MX16-VQG100M covers military temperature requirements and A42MX16-VQG100A covers automotive-screened needs. The antifuse one-time-programmable fabric is intrinsically resistant to configuration upset, a valued property in high-radiation and high-vibration environments where SRAM FPGA configuration errors are a reliability concern.
Recomendado
Telecom and Networking Line-Card Glue Logic
Telecom line cards and backplane adapters use the A42MX16-2VQG100 for clock division, framing-logic assist, LED/status decode, and hot-swap handshaking between MAC/Framer ASICs and the CPU. The 3.3V/5.0V dual-supply architecture lets one device talk to both modern 3.3V ASICs and older 5V PHYs directly. Designers should budget the -2 grade's 117 MHz toggle limit against the line-card reference clock; for 155 MHz SONET-class clocks, move to the -3 speed grade in the same footprint.

Notas de projeto
The MX family is one-time-programmable (antifuse). Once programmed, the device cannot be erased or reprogrammed - a programming error consumes the part. Reserve 15-20% of logic resources for ECO fixes, and simulate thoroughly in the Microchip (Actel) Designer toolchain before committing to programming. Never probe VPP pins during normal operation; the programming voltage is applied only during the programming step.
The A42MX16-2VQG100 uses a 5.0V core with 3.3V/5.0V I/O capability. Decouple each VDD pin with 0.1uF ceramic capacitors placed within 2 mm of the pin, plus one 10uF bulk capacitor per supply rail. Because the 0.45 um process draws modest dynamic current at 117 MHz, thermal management is usually unnecessary, but confirm total dissipation against your toggle activity in the Designer power estimator.
The 100-TQFP (0.5 mm lead pitch) requires careful footprint adherence to the MX datasheet land pattern; avoid hand-routing under fine-pitch leads without solder mask defined pads. Underside thermal relief is not required. For 5V-tolerant I/O interfacing legacy buses, add series 22-33 ohm resistors on outputs driving long traces to control ringing, and keep unused I/O configured as inputs with pull-ups per Microchip application guidance.
