A42MX16-PQ100 개요
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that designers configure after manufacturing. The 42MX family uses antifuse programming technology, which is one-time programmable (OTP), providing non-volatile configuration, high immunity to configuration corruption, and inherent security advantages over SRAM-based FPGAs. This makes MX devices a reliable, single-chip ASIC alternative for high-volume systems.
Key features include 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, support for up to 100% resource utilization and 100% pin locking, and deterministic routing. The 5V-tolerant, 5.0V-capable architecture makes the A42MX16 especially well suited for integrating legacy PLD/CPLD designs into a single low-cost device while maintaining 5V industrial signal compatibility.
Architecturally, the MX family combines combinational and sequential logic modules with embedded dual-port SRAM blocks, fabricated on a 0.45 um process. Deterministic interconnect means timing remains predictable even at full utilization, an important trait for glue logic consolidation, bus interface bridging, and legacy redesigns where behavior must be preserved exactly.
Typical applications include legacy system consolidation, industrial control, 5V bus interfacing, telecommunications line cards, and ASIC prototyping. Pricing as of 2026-08-30 is available from DigiKey, Mouser, and Octopart.
Design note: because MX devices are one-time programmable, verify the full design in simulation and, where possible, use the same family in a reprogrammable flow or footprint-compatible strategy before committing production devices.

일반적인 애플리케이션
A42MX16-PQ100 적합 용도: 6 애플리케이션s: Legacy PLD/CPLD Design Consolidation, 5V Industrial Bus Interfacing, ASIC Prototyping and Low-Volume Emulation, Telecommunications Line Cards, Industrial Motor and Power Control Logic, Test and Measurement Instrumentation.
Legacy PLD/CPLD Design Consolidation
The 42MX family is explicitly marketed by Microchip as a high-volume platform for integrating legacy PLDs into a single, low-cost device. With 24K gates, 608 logic cells, and deterministic antifuse routing, multiple 22V10-class PLDs and small CPLDs can be merged into one A42MX16-PQ100 while preserving exact timing behavior and 5V I/O compatibility. Because configuration is non-volatile and one-time programmable, no external configuration flash is needed, simplifying BOM and improving robustness in long-lifecycle industrial systems.
추천
5V Industrial Bus Interfacing
The A42MX16's flexible 3.3V/5V architecture directly interfaces with 5V TTL-level industrial buses, backplanes, and sensors without level shifters. The PQ100 package provides 83 user I/O, enough for 16/32-bit parallel bus bridges, address decoding with fast wide-decode circuitry, and handshaking logic. Deterministic antifuse interconnect ensures fixed propagation delays, which matters for bus timing margins in legacy replacement designs where behavior must match the original PLD implementation exactly.
추천
ASIC Prototyping and Low-Volume Emulation
As a single-chip ASIC alternative, the A42MX16-PQ100 enables gate-array-style prototyping with up to 54,000 system gates and 2.5 kbits of dual-port SRAM for FIFOs and register files. One-time programmable antifuse technology provides full-speed, radiation-tolerant-like deterministic behavior without SRAM reconfiguration delays, making prototype timing representative of gate-array results. 100% pin locking lets the PCB be designed once while logic is finalized, reducing board spins during ASIC emulation cycles.
추천
Telecommunications Line Cards
Telecom line cards built around 5V backplane standards benefit from the A42MX16's 5V-tolerant I/O, 103 MHz system performance, and glueless interface to framers, HDLC controllers, and TDM switching logic. The dual-port SRAM blocks implement small FIFOs for rate adaptation, while fast wide-decode circuitry handles address and channel decoding at full bus speed. Non-volatile antifuse configuration removes configuration-readout vulnerabilities important in carrier equipment, and the mature 0.45 um process supports long-term product availability.
추천
Industrial Motor and Power Control Logic
In motor drives and power conversion systems, the A42MX16-PQ100 implements PWM generation, dead-time insertion, fault latching, and protection interlocks alongside 5V microcontrollers or DSPs. Deterministic antifuse delays allow precise, predictable PWM edge placement, and immediate-on power-up (no configuration load time) enables safety logic to be active as soon as power is applied - a key advantage over SRAM FPGAs that require boot time. 100% pin locking simplifies PCB layout around fixed connector and gate-driver pin assignments.
추천
Test and Measurement Instrumentation
Bench and automated test equipment frequently mixes 5V legacy instruments with modern 3.3V controllers; the A42MX16-PQ100 bridges these domains with its 3.3V/5V I/O architecture and 83 user I/O pins. Its fast wide-decode circuitry implements trigger comparators, address decoders, and timing-chain logic deterministically, while dual-port SRAM provides small capture buffers. The non-volatile antifuse configuration is immune to power-cycle corruption, ensuring instruments behave identically at every power-up, which is essential for repeatable measurements.

설계 노트
The A42MX16-PQ100 operates from a 3.3V/5V architecture per the Microsemi DS2316 datasheet. Connect all VCC and ground pins in the 100-pin PQFP as specified in the datasheet pin tables, and provide the VPP programming supply required for antifuse programming during the programming stage only. Decouple each supply pin with 0.1uF ceramic capacitors placed close to the package, and verify total I/O switching current against the datasheet DC characteristics to size the 5V rail appropriately.
The MX family is one-time programmable antifuse silicon: a programmed A42MX16 cannot be erased or reprogrammed. Complete full functional simulation, timing verification, and preferably a bench-proven design before committing production devices. Establish 100% pin locking early, since the antifuse architecture locks routing and pin assignments deterministically; late pin changes require device replacement rather than a bitstream update.
The 100-pin PQFP (BQFP) has fine-pitch leads requiring careful land-pattern design per the mechanical drawing in DS2316. Use a no-clean or water-washable paste with 0.5mm pitch stencil apertures, inspect leads for solder bridging with X-ray or AOI, and avoid excessive reflow peak temperatures on this mature 0.45 um process device. The BQFP body is taller and more mechanically exposed than TQFP - add clearance and consider lead coplanarity inspection at incoming QC.
When interfacing 5V buses, group fast-switching outputs away from sensitive input pins and use the fast wide-decode circuitry for address decoding rather than long ripple-carry chains to minimize glitch-sensitive decode outputs. Because antifuse routing is deterministic, extracted delays from Libero timing reports are reliable; still, series-terminate heavily loaded 5V bus lines to control reflections at backplane connectors.
