A42MX09-PLG84A Visão geral
An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC whose interconnect and logic function are configured by the designer after manufacturing, sitting within the broader hierarchy of programmable logic devices (PLD -> CPLD -> FPGA). The MX family uses antifuse programmability, providing non-volatile configuration, low power, and instant-on operation that distinguish it from SRAM-based FPGAs.
Key features include up to 54,000 equivalent system gates in the family, 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, 5.6 ns clock-to-out, 250 MHz performance, and 5 ns dual-port SRAM access supporting 100 MHz FIFOs. The A42MX09 density offers 14K gates and is rated for automotive applications per distributor data (5V, 84-pin PLCC, 0.45 um technology, up to 192 MHz cell performance as listed by Jotrin).
Typical applications include legacy PLD consolidation, industrial control, defense and avionics upgrades of 5V systems, glue-logic integration, and high-volume boards where a low-cost, non-volatile single-chip ASIC replacement is desired.
When designing with this device, note that 5.0 V I/O makes it ideal for interfacing with legacy TTL/5V-CMOS buses but incompatible with 3.3V-only systems without level translation; verify speed-grade suffix and programming support (e.g., Microchip Libero/Designer tools) before layout.

Aplicações típicas
A42MX09-PLG84A é adequado para 6 aplicaçãos: Legacy PLD Consolidation, Industrial Control Systems, ASIC Prototyping and Replacement, Defense and Avionics Upgrades, Automotive Electronics, Communications and Data Buffering.
Legacy PLD Consolidation
The A42MX09-PLG84A fits applications where multiple legacy PLDs, PALs, and glue-logic devices are integrated into a single 5V-tolerant chip. Its 14K gates and 72 user I/O absorb address decoding, bus interfacing, and state machines that previously occupied several packages. Because the MX antifuse fabric is non-volatile and active at power-up, no configuration PROM or boot sequence is required - a decisive advantage when retrofitting legacy boards. Consolidation reduces BOM count, board area, and assembly cost while preserving the original 5.0 V I/O signaling levels.
Recomendado
Industrial Control Systems
Industrial controllers built around 5V buses benefit directly from the A42MX09-PLG84A. Its 5.0 V architecture interfaces natively with legacy TTL/CMOS sensors, actuators, and optocoupler front ends without level shifters, while 336 logic cells and 2.5 kbits of dual-port SRAM implement control sequencing, FIFO buffering, and handshaking logic. With 100 MHz FIFO capability and 5 ns SRAM access, it handles fast data-path tasks in factory automation equipment. The 84-PLCC J-lead package offers robust surface-mount reliability suited to vibration-prone industrial environments and straightforward rework.
Recomendado
ASIC Prototyping and Replacement
As a single-chip ASIC alternative, the A42MX09-PLG84A serves both prototyping and permanent replacement of mask ASICs in mid-volume products. Antifuse programming locks the design once and for all - no configuration data is exposed, which matters for IP protection - while eliminating NRE charges and mask lead times of custom ASICs. The 0.45 um process supports 250 MHz-class performance in the family with 5.6 ns clock-to-out on the MX09 density, sufficient for many control and data-formatting functions originally targeted at gate arrays. Production quantities are available through standard distribution.
Recomendado
Defense and Avionics Upgrades
Defense and avionics sustainment programs frequently must keep 5V legacy hardware alive. The A42MX09-PLG84A addresses this with a 5V, non-volatile antifuse architecture that survives radiation-tolerant screening options in the MX family and requires no configuration memory that could be corrupted. Its 14K gates replace obsolete bipolar and CMOS logic boards, and the ceramic-compatible PLCC-84 mounting supports existing sockets on older boards. Instant-on operation removes boot-time constraints in safety-related systems, and Microchip's long-lifecycle policy on MX devices supports multi-decade sustainment plans.
Recomendado
Automotive Electronics
Distributor data lists the A42MX09-PLG84A as an automotive-rated member of the 42MX family. In vehicle applications it implements body-control glue logic, sensor conditioning interfaces, and protocol bridging on legacy 5V subsystems where 3.3V FPGAs would need extensive translation. The dual-port SRAM (5 ns access) supports buffered communication between ECUs and instrumentation, while antifuse non-volatility eliminates configuration flash that is vulnerable to noise transients in harsh electrical environments. Its 84-PLCC package withstands under-hood-adjacent thermal cycling with standard surface-mount assembly.
Recomendado
Communications and Data Buffering
The MX09 dual-port SRAM and wide-decode resources suit communications line cards and data-formatting pipelines. With 5 ns dual-port access and 100 MHz FIFO capability, the A42MX09-PLG84A implements rate adaptation between 5V legacy interfaces and faster internal logic, plus address generation for packet buffering. Fast wide-decode circuitry (to 202 user-programmable I/O pins in the wider family, 72 on this package) enables rapid address mapping. Because it is non-volatile, line cards power up functional immediately after hot-swap, simplifying system-level bring-up in telecom shelves.

Principais diferenciais
- 5.0 V native I/O architecture (vs A42MX16-2PLG84)
- Non-volatile antifuse configuration (vs SRAM-based competitor FPGAs)
- Dual-port SRAM with 5 ns access and 100 MHz FIFO support (vs A42MX09-PLG84M)
Notas de projeto
The A42MX09-PLG84A operates from a single 5.0 V supply per MX family architecture. Decouple VCC with at least 0.1 uF ceramic per supply pin plus bulk 10 uF near the device. Because antifuse FPGAs draw no configuration current at power-up, inrush is dominated by I/O loading, but verify static and dynamic ICC against your utilization in the Microchip Designer timing/power reports rather than datasheet maxima.
The 84-PLCC J-lead package suits both socketed and direct surface-mount assembly. If using a PLCC socket for field-replaceable legacy upgrades, account for socket contact resistance and added lead inductance on fast (5.6 ns) clock-to-out paths. Keep ground return paths short beneath the package and avoid routing high-speed clocks on the J-lead corners where inductance is highest.
Three frequent mistakes with this part: (1) assuming bitstream compatibility with other A42MX09 order codes - verify the exact speed grade and die in your Libero/Designer project before programming; (2) forgetting that antifuse devices are one-time programmable - reserve engineering samples for iterations; (3) mixing the PLG84 (green/lead-free) with legacy non-G PL84 footprints in reflow profiles - the A-suffix/G package requires lead-free assembly temperatures.
