A42MX09-1PQG160 - 14K Gate MX FPGA 160-PQFP | Microchip
MPN： A42MX09-1PQG160 ✓ 啟用中A42MX09-1PQG160 概覽
The MX family is a class of antifuse-based, one-time-programmable (OTP) FPGAs designed as a reliable single-chip ASIC alternative. Unlike SRAM FPGAs, antifuse devices retain their configuration permanently, require no external boot flash, and are inherently immune to configuration-bit upsets - which is why MX devices remain popular in legacy industrial, defense, and high-reliability systems.
Key features include a 5.0V-tolerant architecture suited for legacy PLD consolidation, 14K system gates in a low-cost package, deterministic interconnect delays typical of antifuse routing, and JTAG boundary-scan testing support. The -1 speed grade balances performance and cost, while the 160-PQFP package offers gull-wing leads compatible with standard surface-mount assembly.
Architecturally, the 42MX combines combinatorial and sequential logic modules on a segmented antifuse routing fabric, giving predictable timing that simplifies closure on legacy designs. The device is programmed once via the Microchip (Actel) programming flow and requires no configuration PROM, reducing BOM count and improving boot reliability.
Typical applications include legacy PLD/ASIC replacement, industrial control glue logic, military and avionics upgrades, and bridge/interface functions in 5V legacy systems. The device is especially valued for obsolescence-driven redesigns where a proven, non-volatile fabric is required.
Design consideration: because the MX fabric is OTP, exhaustively verify the design in simulation and on a -3 (faster) or lower-density evaluation device before committing production units - there is no reprogramming.

典型應用
A42MX09-1PQG160 適用於 6 應用s: Legacy PLD Consolidation, Industrial Control and Glue Logic, Defense and Avionics Upgrades, Obsolescence-Driven ASIC Replacement, Bridge and Interface Functions in 5V Systems, Instant-On Embedded Control.
Legacy PLD Consolidation
The A42MX09-1PQG160 is designed by Microchip specifically to integrate legacy PLDs into a single low-cost device, per the MX family positioning as a high-volume ASIC alternative. Its 14K system gates and 101 user I/O absorb multiple 22V10-class or small CPLD functions, while the 5.0V-tolerant architecture matches the signaling of legacy boards without level shifters. Because the antifuse fabric is non-volatile, consolidated logic is active immediately at power-up, matching the behavior of the original PLDs and eliminating configuration delays in systems that assume instant-on logic.
推薦
Industrial Control and Glue Logic
In industrial controllers, the A42MX09-1PQG160 serves as deterministic glue logic between microprocessors, buses, and peripherals. The antifuse interconnect gives fixed, predictable routing delays, so timing closure done once remains valid for the life of the program - important for long-lifecycle factory equipment. Its 3.3V/5V operation bridges legacy 5V sensor and actuator interfaces with newer 3.3V controllers, and the 224 MHz maximum toggle capability comfortably covers typical bus arbiters, address decoders, and state machines running well below 50 MHz.
推薦
Defense and Avionics Upgrades
Military and avionics platforms favor the A42MX09 because antifuse configuration contains no stored bitstream that can be disturbed by radiation-induced upsets, and the device needs no configuration PROM that could fail in the field. The PQG160M screening variant supports harsher environments. In upgrade programs, the 14K-gate A42MX09-1PQG160 replaces obsolete custom logic on existing 160-PQFP footprints, extending service life of airframe and ground-system electronics while preserving proven 5V interface compatibility with older line-replaceable modules.
推薦
Obsolescence-Driven ASIC Replacement
When a custom ASIC or gate array reaches end-of-life, the A42MX09-1PQG160 provides a single-chip migration path: 14K gates of one-time-programmable fabric at commodity pricing, in a package that many legacy ASIC sockets mechanically accept. Microchip markets MX explicitly as a reliable single-chip ASIC alternative for high-volume platforms. Engineering teams re-target the gate-level netlist to the MX fabric using the Libero/Microsemi flow, verify timing against antifuse routing delays, and program production devices without NRE charges or mask costs.
推薦
Bridge and Interface Functions in 5V Systems
The device implements bus bridges, protocol converters, and interface adapters where 5V signaling must interoperate with 3.3V subsystems. Its 3.3V/5V dual operation and 101 I/O enable direct connection to ISA, VME, and proprietary backplanes while interfacing modern peripherals. The non-volatile antifuse fabric presents interface logic instantly at power-up, avoiding the bus-hi-Z windows that SRAM FPGAs need for configuration - a genuine advantage in backplane systems where a slave must respond within milliseconds of power application.
推薦
Instant-On Embedded Control
Applications that require functional logic within microseconds of power - motor sequencing, safety interlocks, watchdog and reset management - benefit from the A42MX09's zero-configuration-boot antifuse fabric. Unlike SRAM FPGAs that spend 10s to 100s of milliseconds loading a bitstream, the A42MX09-1PQG160 is active immediately, so safety-critical enable/disable logic never has an unprotected window. Its 14K gates are ample for interlock state machines, redundant-voter circuits, and sequencing controllers in medical and industrial power systems.

設計說明
The A42MX09 is one-time programmable - a programmed device is permanent. Complete full functional simulation and timing analysis in the Microchip Libero/Designer flow before submitting devices for programming, and order extra programmed spares. Do not treat MX parts like SRAM FPGAs during prototyping; reserve rework cycles for unprogrammed units only.
The 42MX family supports 3.3V/5V operation on a 0.45 um process. Verify per-bank I/O voltage against the DS2316 datasheet tables and decouple VCC/VCCA pins with 0.1 uF ceramics placed within 5 mm of each supply pin. Antifuse devices have low, static quiescent current, so thermal design is usually trivial at this gate count, but confirm against your actual I/O switching activity.
For 5V-legacy boards, match trace impedance and add series termination (22-33 ohm) on outputs driving long buses; antifuse I/O edges can be fast enough to ring on unterminated legacy wiring. Use the JTAG boundary-scan chain (IEEE 1149.1 support in the MX family) to validate board-level connections before programming final fuses, since pin swap fixes after programming are impossible.
