A42MX09-3PLG84I Descripción general
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks and programmable interconnects that the designer wires together after manufacturing, sitting in the programmable-logic hierarchy between CPLDs and full gate-array ASICs. The Microchip/Microsemi MX (40MX and 42MX) families were engineered specifically as low-cost, single-chip ASIC alternatives at 5.0 V, letting designers consolidate legacy PLD, glue-logic, and bus-interface functions into one device for high-volume systems.
Key features of the A42MX09 include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, 250 MHz internal performance, 5 ns dual-port SRAM access, and 100 MHz FIFO capability. The -3 speed grade and the widely available 84-PLCC package make this member attractive for through-hole-friendly, J-lead surface-mount boards that must keep a 5 V I/O ecosystem alive.
Technically, the MX family is fabricated on a 0.45 um process and provides 336 logic cells for this density, with core and I/O operation at 5.0 V. The Actel/Microsemi antifuse-style programming heritage means configuration is non-volatile and immediately active at power-up, unlike SRAM FPGAs that need a configuration PROM.
Typical applications include legacy 5 V industrial control, military/aerospace board upgrades, telecommunications line cards, and consolidation of multiple 22V10/PLD devices into a single chip.
Designers should verify I/O banking rules and power distribution on the 84-PLCC footprint, and confirm the -3 speed grade meets timing for 129 MHz to 215 MHz clocking scenarios.

Aplicaciones típicas
A42MX09-3PLG84I es adecuado para 6 aplicacións: Legacy 5V Industrial Control, Aerospace and Defense Board Upgrades, Telecommunications Line Cards, PLD Consolidation / Glue Logic Replacement, Test and Measurement Equipment, Medical Device Legacy Sustaining.
Legacy 5V Industrial Control
The A42MX09-3PLG84I is a natural fit for 5.0 V industrial control boards still running TTL-level I/O. Its native 5 V architecture connects directly to PLC backplanes, motor-drive controllers, and sensor buses without level shifters, while 14K gates and 72 user I/O absorb multiple legacy PLDs and glue-logic devices into one package. The -3 speed grade supports control loops clocked up to 250 MHz internally, and the 2.5 kbit dual-port SRAM buffers data between asynchronous subsystems. Industrial plants often keep 5 V equipment alive for decades, and the industrial -40C to +85C rating plus non-volatile, live-at-power-up configuration makes this part a low-risk modernization path for such installed bases.
Recomendado
Aerospace and Defense Board Upgrades
Defense and aerospace programs frequently sustain 5 V avionics and ground-system boards designed around Actel MX antifuse FPGAs. The A42MX09-3PLG84I keeps that supply chain viable: the PLG84 footprint is unchanged from legacy drawings, configuration is non-volatile so boards power up functional without a configuration device, and the M-suffix sibling (A42MX09-3PLG84M) covers military screening flows. The 14K gate density suits bus interfaces, telemetry encoders, and sequencer logic. Designers upgrading older PLD-based boards consolidate decode, arbitration, and status logic into this single chip, reducing component count and improving reliability in radiation-tolerant-adjacent, high-vibration, wide-temperature environments.
Recomendado
Telecommunications Line Cards
Telecom line cards benefit from the A42MX09-3PLG84I's combination of fast embedded memory and wide-decode logic. The 5 ns dual-port SRAM and 100 MHz FIFO support handle data-path elasticity, T1/E1 framing buffers, and bus width conversion, while 336 logic cells implement HDLC controllers, address decoders, and clock-domain bridging. The -3 speed grade delivers 5.6 ns clock-to-out for fast external bus turnaround. Because the MX family operates at 5.0 V, it interfaces directly with legacy line-card chipsets built before the 3.3 V transition, letting carriers extend the life of installed central-office equipment without redesigning the entire card.
Recomendado
PLD Consolidation / Glue Logic Replacement
A common MX use case is collapsing a handful of 22V10 CPLDs, GALs, and TTL glue chips into one FPGA. The A42MX09-3PLG84I's 14K gates and 72 I/O comfortably absorb address decoding, wait-state generation, interrupt control, and simple state machines, cutting board area, BOM lines, and assembly cost. Fast wide-decode circuitry keeps decode paths in the nanosecond range, matching the timing expectations of legacy microprocessor buses. Because MX configuration is non-volatile and immediately active, the consolidated design powers up exactly like the original PLD solution, an important compatibility property when board revisions must remain software- and firmware-transparent to field technicians.
Recomendado
Test and Measurement Equipment
Bench instruments and automated test fixtures often contain 5 V subsystems - relay drivers, trigger logic, timing generators - where the A42MX09-3PLG84I excels. Its deterministic, non-volatile configuration means the instrument is ready at power-up with no configuration download delay, and the 250 MHz internal performance supports precision timing generators and trigger state machines. The dual-port SRAM implements capture buffers or pattern memory without external RAM. The 84-PLCC J-lead package is easy to socket and rework in maintenance-heavy lab equipment, and the industrial temperature rating tolerates uncontrolled environments such as production-floor test stations and environmental chambers.
Recomendado
Medical Device Legacy Sustaining
Long-lifecycle medical equipment - analyzers, imaging subsystems, patient monitors - commonly embeds MX FPGAs in 5 V sections that must be sustained for regulatory and service reasons. The A42MX09-3PLG84I allows footprint-identical replacements that keep design history files intact, a significant advantage under design-control change management. Its non-volatile configuration removes configuration-device failure modes relevant to device safety reviews, and the industrial -40C to +85C range covers cold-chain transport and storage requirements. Because only the speed grade and finish change versus other A42MX09 PLG84 order codes, form-fit-function documentation updates remain minimal and validation effort is contained.

Notas de diseño
The MX family operates from a single 5.0 V supply. Estimated: with tens of mA of I/O switching and the -3 grade, budget at least 100-200 mA per device on the 5 V rail and verify with Libero power analysis for your specific design. Place 0.1 uF ceramic decoupling capacitors at each of the four corner VCC/GND pin pairs of the 84-PLCC plus one bulk 10 uF per device. Because PLCC power pins are distributed around the package, a solid 5 V plane is strongly recommended rather than routed power traces.
The PLG84 footprint is the classic J-lead PLCC-84 land pattern; when qualifying a lead-free (I-suffix) replacement for a tin-lead design, confirm your assembly profile supports SAC-type solders at the J-leads, which sit under the package body and need good flux delivery. Keep unused I/O configured per the MX recommended practice (input with pull-up or driven output) rather than floating, to avoid excess static current and noise pickup on the 5 V bus.
The -3 speed grade is the fastest MX09 grade, but static timing must still be run in Libero SoC for your actual design - do not assume 250 MHz on every path. If substituting A42MX09-2PLG84I or -1PLG84I during shortages, re-run timing before release; the slower grades reduce margin on every register-to-register path. Also note the ordering-code trap: A42MX09-3PLG84 without the I is commercial temperature and legacy finish - ordering the wrong suffix can stall industrial-temperature builds.
