A42MX16-1PQG160 Présentation
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer wires together post-manufacture, sitting in the programmable-logic hierarchy between CPLDs and full ASICs. The MX family is distinctive for its antifuse-based, non-volatile fabric and efficient 5.0V architecture, making it a reliable single-chip ASIC alternative for integrating legacy PLD designs into one low-cost, high-volume device.
Key features include the 5.0V-tolerant architecture that directly interfaces with legacy 5V bus systems without level shifters, antifuse program-once technology that is inherently secure and resistant to configuration readback, and commercial temperature range operation (0C to +70C, indicated by the absence of the I industrial suffix). The PQFP-160 surface-mount package supports standard reflow assembly.
Architecturally, the MX fabric combines logic modules with embedded routing channels optimized for high fan-in functions, suiting glue logic consolidation, state machines, bus interfacing, and control-path implementations. Design entry and programming use the Microchip (Microsemi) Libero SoC design suite.
Typical applications include legacy 5V industrial control boards, telecommunications line cards, mil-aero legacy redesigns, and high-volume consumer/industrial products where a one-time-programmable, tamper-resistant fabric is preferred over SRAM FPGAs.
Design consideration: because MX antifuse devices are one-time programmable, fully verify the design in simulation and, if possible, on a higher-density MX device before committing the production die. Pricing referenced is as of 2026-08-30; verify current stock as this mature family is often sourced through distribution allocation.

Applications typiques
A42MX16-1PQG160 convient pour 6 applications: Legacy 5V Industrial Control Board Redesign, Secure Anti-Tamper Logic, Telecommunications Line Cards, High-Volume Consumer and Appliance Control, Test and Measurement Instrumentation, Mil-Aero and Transportation Legacy Sustainment.
Legacy 5V Industrial Control Board Redesign
The A42MX16's native 5.0V architecture directly interfaces with legacy TTL, ABstd-B, and 5V CMOS bus systems without level translators, which is why it remains a favored ASIC alternative for maintaining older industrial controllers. With 1,232 logic cells and 125 user I/O, one A42MX16 can consolidate multiple 22V10-class PLDs and glue logic into a single antifuse die, reducing BOM count and board area. The one-time-programmable fabric also powers up instantly with no configuration device, improving system boot reliability in factory equipment.
Recommandé
Secure Anti-Tamper Logic
Antifuse FPGAs are preferred where configuration security matters: unlike SRAM FPGAs, the A42MX16 stores its design physically in antifuse interconnect elements with no bitstream to intercept or read back. This makes it suitable for defense, gaming, and DRM-adjacent logic that must resist design extraction. The 24K-gate capacity accommodates authentication state machines, key-check logic, and protocol wrappers, while instant-on, non-volatile startup eliminates the configuration window that SRAM devices expose at power-up.
Recommandé
Telecommunications Line Cards
The MX family was widely deployed in telecom backplanes and line cards operating on 5V signaling. The A42MX16's 125 user I/O handle parallel data paths, TDM framing logic, and backplane handshaking at clock rates up to 94 MHz, adequate for E1/T1 framing and legacy PDH transport functions. Its commercial 0C to +70C rating suits central-office environments, and the 160-lead PQFP with 0.655 mm pitch supports standard reflow assembly on telecom PCBs designed around through-hole-era footprints upgraded to SMT.
Recommandé
High-Volume Consumer and Appliance Control
Microchip positions MX as a high-volume, low-cost ASIC alternative: the A42MX16 avoids ASIC NRE charges and mask lead times while providing hard-wired, one-time-programmed behavior identical from unit to unit. At 24K gates and 1,232 logic cells, it implements appliance sequencers, motor-control glue logic, keypad scanning, and display controllers. Unit pricing around $30 at 1K volume (as of 2026-08-30) and instant-on startup make it cost-competitive against microcontroller plus CPLD combinations in cost-sensitive products.
Recommandé
Test and Measurement Instrumentation
Bench instruments and ATE fixtures frequently retain 5V logic interfaces; the A42MX16 bridges this directly with its 5.0V-tolerant I/O and 125 available pins for stimulus/response channels. Its deterministic, one-time-programmed timing avoids SRAM FPGA configuration variability, and the -2 or -3 speed grades provide up to 94 MHz-plus toggle capability for counter, encoder, and trigger-path logic. Boundary-scan cells chained from TDI to TDO (per DS2316) support in-system interconnect testing of instrument backplanes.
Recommandé
Mil-Aero and Transportation Legacy Sustainment
Programs built on Actel MX silicon continue to require form-fit-function replacements; the A42MX16-1PQG160 sustains such platforms with identical die and package. Antifuse fabric tolerates radiation-induced configuration upsets better than SRAM (no configuration memory to corrupt), and its non-volatile instant-on behavior suits avionics and vehicle control units that must be operational at first power cycle. The industrial-temperature A42MX16-1PQG160I variant covers extended-environment deployments with the same footprint.

Principaux différenciateurs
- Native 5.0V I/O eliminates level shifters (vs A42MX16-2PQG160)
- Antifuse security with instant-on startup (vs XC4000XLA-class SRAM FPGAs)
- Industrial temperature drop-in available (vs A42MX16-1PQG160I)
Notes de conception
Decouple each VDD pin with 0.1 uF ceramic capacitors placed within 5 mm of the pin, plus at least one 10 uF bulk capacitor per device. The 5.0V MX fabric draws transient shoot-through current during logic transitions; an inadequate power plane causes intermittent timing failures that are difficult to diagnose on OTP devices. Measure supply ripple under worst-case toggling patterns before committing the design to antifuse programming.
Antifuse programming is irreversible. Complete full post-layout timing simulation in Libero SoC and, where feasible, validate on an A42MX24 (larger die, same family) or a prototype A42MX16 before burning production parts. Reserve approximately 20% logic headroom; designs exceeding 80% utilization risk route congestion failures that cannot be fixed after programming.
The 160-lead PQFP with 0.655 mm pitch requires solder-mask-defined or non-solder-mask-defined pads per IPC-SM-782-style QFP land patterns; use 0.55 mm-wide lands with 0.65 mm pitch routing escape. Keep clock traces length-matched and away from I/O returns. Inspect QFP leads with X-ray or 3D AOI to catch coplanarity-related open joints after reflow.
The boundary-scan chain (TDI through all cells to TDO, per DS2316) enables interconnect test after assembly. Use TCK series termination (22-33 ohm) to limit ringing, and do not leave TMS/TDI floating - pull TMS high through 10K ohm. Undriven JTAG inputs on 5V fabric can float into indeterminate levels and cause scan-chain lockup during production test.
