A42MX09-2PLG84I 개요
An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC that implements custom digital circuits through a matrix of configurable logic blocks and programmable interconnects. Within the programmable logic hierarchy, the MX family sits as a cost-effective, single-chip ASIC alternative positioned below high-end FPGA families, making it a platform for consolidating legacy PLDs into one low-cost device.
Key features include 250 MHz system performance, 5.6 ns clock-to-out, 5 ns dual-port SRAM access, up to 2.5 kbits of configurable dual-port SRAM, and fast wide-decode circuitry. The -2 speed grade balances performance and cost, and the 5.0V-tolerant architecture uniquely suits 5V legacy bus integration where modern low-voltage FPGAs require level shifters.
The MX architecture uses a 0.45 um process with act-three antifuse-style and reprogrammable configuration options across the family, offering high volume production reliability with no configuration PROM required for certain family members. Designers typically use Libero SoC design tools from Microchip for synthesis and place-and-route.
Typical applications include industrial control, legacy PLD consolidation, glue-logic integration, military/industrial upgrade programs, and 5V bus bridging in mixed-voltage systems. The industrial -40C to +85C rating supports harsh environments.
Design consideration: verify 5V/3.3V dual-rail sequencing on the PCB and confirm I/O bank voltage assignment early, since the 84-PLCC footprint offers limited I/O for late design changes.

일반적인 애플리케이션
A42MX09-2PLG84I 적합 용도: 6 애플리케이션s: Legacy PLD Consolidation, Industrial Control and Automation, 5V Bus Bridging and Glue Logic, ASIC Prototyping and Emulation, Military and Aerospace Upgrade Programs, Test and Measurement Equipment.
Legacy PLD Consolidation
The A42MX09-2PLG84I integrates multiple legacy PLDs, PALs, and GALs into a single 14K-gate device, reducing board area, BOM line items, and assembly cost. Its 5.0V architecture matches the legacy 5V logic environment directly, eliminating level shifters that 3.3V or 1.8V FPGAs would require. With 336 logic cells and fast wide-decode circuitry, address decoders and bus interfaces from older designs map efficiently. Migration to the pin-compatible MX16 or MX24 variants provides headroom if the consolidated logic outgrows 14K gates without any PCB change.
추천
Industrial Control and Automation
With a -40C to +85C industrial rating and 5V-tolerant I/O, the A42MX09-2PLG84I drives PLC I/O modules, motor control sequencing, and sensor interfacing in factory automation. The 72 user I/O pins implement parallel fieldbus transceivers, and the -2 speed grade's 5.6 ns clock-to-out supports deterministic control loops at tens of MHz. Dual-port SRAM enables ping-pong buffering between control logic and a host microcontroller. Designers should verify conduction cooling in sealed enclosures, since the PLCC-84 package has modest thermal performance.
추천
5V Bus Bridging and Glue Logic
Many military upgrade and telecom-legacy systems still run 5V backplanes. The MX family's 5.0V core with 3.3V/5V I/O operation lets the A42MX09-2PLG84I bridge 5V buses to 3.3V subsystems on-chip, replacing TTL glue logic with a single programmable device. Fast wide-decode FUBs handle address decoding at 250 MHz-class internal performance. Because it is reprogrammable in-circuit across the MX family tool flow, bus protocol changes are absorbed with a design update rather than a board respin, protecting long-lifetime platforms from obsolescence.
추천
ASIC Prototyping and Emulation
The MX family serves as a reliable single-chip ASIC alternative, and the A42MX09-2PLG84I is commonly used to prototype small ASIC blocks or emulate control logic before tape-out. The 2.5 kbits of configurable dual-port SRAM (5 ns access) models on-chip memories and FIFOs, while 336 cells accommodate datapath fragments. Running at up to 250 MHz internal performance, it validates functional behavior at speeds close to target ASIC clocks. Libero SoC timing reports provide first-order timing estimates, though antifuse/Flash-based timing differs from standard-cell ASIC libraries.
추천
Military and Aerospace Upgrade Programs
MX FPGAs originate from Microsemi heritage with military temperature options across the family (e.g., A42MX09-TQG176M), and the industrial-grade A42MX09-2PLG84I supports upgrade boards in defense platforms that must preserve 5V interfaces. The single-chip, high-reliability architecture suits long-lifecycle programs where design stability matters more than cutting-edge process nodes. Its 0.45 um mature process avoids single-event-latch-up sensitivity typical of deep-submicron devices. Consult Microchip military product briefs for screening flows (883-class options exist within the broader MX portfolio).
추천
Test and Measurement Equipment
Bench instruments and ATE modules use the A42MX09-2PLG84I for timing generators, trigger logic, and pattern decoders. The 5 ns dual-port SRAM access and 100 MHz FIFO capability implement deep capture buffers, while fast wide-decode circuitry recognizes trigger patterns across 72 I/O channels. The -2 speed grade provides timing margin for 50-100 MHz state machines in rack-based instruments. Its deterministic pinout and industrial temperature range also suit production-floor test heads where ambient conditions vary throughout the day.

설계 노트
The A42MX09-2PLG84I requires two supply rails: 5V (4.5-5.5V) for the core and 3.3V (3.0-3.6V) for I/O. Decouple each rail with at least 0.1 uF ceramic per power pin plus 10 uF bulk near the device. Confirm rail sequencing per the MX datasheet power-up specification to avoid I/O latch-up during configuration; if in doubt, use a supervisor such as a TPS3839 to hold reset until both rails are stable.
The 84-PLCC J-lead footprint requires careful land-pattern adherence to JEDEC MS-018 dimensions for reliable solder joints after reflow. Avoid routing high-speed clocks under the package center; PLCC packages lack a thermal pad, so keep switching IO return paths short with a solid ground plane. Reserve the footprint to accept MX16/MX24 pin-compatible upgrades - same land pattern supports A42MX16-3PLG84I and A42MX24-3PLG84I for capacity changes without respin.
Do not assume timing parity across speed grades: designs closed at -3 timing will not necessarily meet timing at -2 or -1. Also verify I/O bank assignments early - the 84-PLCC has only 72 user I/O, so pin budgeting errors discovered late force board respins. Finally, the MX family is a mature 0.45 um product line; check lifecycle status with Microchip before starting new designs and lock in a last-time-buy strategy for long-lifetime programs.
