Typical Applications
A42MX16-1VQG100M is suitable for 6 applications: Legacy PLD Consolidation, Industrial Control and Automation, Design-Secure Glue Logic, Mil-Aerospace and Defense Subsystems, ASIC Prototyping and Low-Volume ASIC Replacement, Bus Interface and Protocol Bridging.
Legacy PLD Consolidation
The A42MX16-1VQG100M integrates multiple legacy PAL, GAL, and CPLD devices into a single antifuse FPGA, per Microchip's MX positioning for legacy PLD integration. With 24,000 gates and 83 user I/O, several 22V10-class PLDs plus glue logic typically collapse into one device, cutting BOM count and board area. Because configuration is non-volatile and instant-on, replacement boards power up with no configuration delay, matching original PLD behavior. Logic is re-entered in Libero SoC and fitted to the MX fabric, preserving function while modernizing supply.
Recommended
Industrial Control and Automation
In industrial controllers and motor-drive interface boards, the A42MX16-1VQG100M provides deterministic, instant-on logic with 108 MHz maximum clock capability and 3.3 V I/O. The antifuse configuration cannot be corrupted by power glitches, brownouts, or EMI events that can flip SRAM FPGA cells - a meaningful reliability advantage on noisy factory floors. Its single-chip nature removes the external configuration flash, improving MTBF. With 83 I/O it can bridge encoders, limit switches, and communication transceivers to a host processor efficiently.
Recommended
Design-Secure Glue Logic
For systems requiring IP protection, the A42MX16-1VQG100M's antifuse interconnect is physically formed and cannot be read back, unlike SRAM FPGAs whose bitstreams can be intercepted at boot. This makes it well suited to proprietary interface translation, custom bus bridges, and authentication logic. The 24K-gate capacity with 608 CLBs accommodates address decoders, state machines, and protocol adapters. Security is combined with instant-on operation: protected logic is active the instant power is applied, with no configuration window to exploit.
Recommended
Mil-Aerospace and Defense Subsystems
The MX family's antifuse technology is inherently tolerant of radiation-induced configuration upset because there is no volatile configuration memory to disturb, a key reason Microsemi MX FPGAs serve defense and aerospace boards. The A42MX16-1VQG100M suits non-flight, ground-based, and legacy defense platforms needing deterministic glue logic and bus interfacing. Instant-on non-volatile configuration suits munitions and rapidly powered subsystems. For full temperature range requirements, the industrial -I speed variants of the same die should be evaluated during design.
Recommended
ASIC Prototyping and Low-Volume ASIC Replacement
Microchip positions MX FPGAs as a reliable single-chip ASIC alternative for high volume at low cost. The A42MX16-1VQG100M implements 24K gates of ASIC-like glue logic with permanent, deterministic interconnect - no configuration loading time and no SRAM reliability concerns. For gate-array replacements around 20K gates, the A42MX16 often replaces a full custom ASIC without NRE mask charges. Design once in Libero SoC, program the antifuse die, and ship a genuinely single-chip solution with ASIC-like power-up behavior.
Recommended
Bus Interface and Protocol Bridging
With 83 user I/O and 108 MHz maximum clock rate, the A42MX16-1VQG100M handles parallel bus bridging tasks - ISA/PCI-legacy style interfaces, memory bus translation, and backplane interconnect adaptation. The 5.0 V-tolerant flexible architecture simplifies interfacing to older 5 V systems while the core operates at 3.3 V nominal (3.0-3.6 V range). Deterministic antifuse routing delivers consistent timing across production units, which matters for interface timing closure. State machines, FIFOs, and decoders fit comfortably in 608 CLBs.

Key Differentiators
- Instant-on non-volatile configuration (vs SRAM FPGAs (e.g., Xilinx Spartan family))
- Native read-back protection (vs A42MX16-1VQG100 vs SRAM devices)
- Capacity/cost balance in MX family (vs A42MX09-2VQG100)
Design Notes
The A42MX16 is one-time programmable antifuse silicon - there is no erase or rework path once programmed. Complete full functional simulation and timing verification in Libero SoC before submitting the design to programming. Order unprogrammed evaluation or use the simulator flow to validate state machines and I/O assignments; a pinout error discovered after programming requires a new die.
Operate the core/IO supply at 3.3 V nominal within the 3.0-3.6 V range and decouple each VDD pin with 0.1 uF ceramic capacitors placed within 2 mm of the pin, plus bulk 10 uF near the device. MX antifuse FPGAs have no configuration inrush current, simplifying power sequencing compared to SRAM FPGAs - no power-up ramp constraint from a configuration device exists.
The 100-TQFP (VQG100) has a 0.5 mm pin pitch; use a standard Gull-wing TQFP-100 land pattern per the Microsemi package drawing. Keep global clock inputs (CLKA/CLKB) routed short and away from switching I/O to preserve the 108 MHz timing budget. Unused I/O should be configured per datasheet defaults to avoid floating nodes.
Compliance Information
Distributor listings (PCB Electronics, Mouser) identify A42MX16-1VQG100M as lead free. REACH, halogen-free, and conflict-minerals status not stated in provided data - verify on Microchip product page.
