A42MX16-FPLG84 - 24K Gate FPGA 84-PLCC | Microchip Technology
MPN: A42MX16-FPLG84 ✓ فعالA42MX16-FPLG84 جائزہ
An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC whose interconnect and logic function blocks are configured by the designer after manufacturing. Within the programmable logic hierarchy (FPGA -> programmable logic device -> programmable IC -> semiconductor), the MX family is an antifuse-based FPGA designed as a single-chip ASIC alternative and a platform for consolidating legacy PLDs into one low-cost device.
Key features of the A42MX16 include the flexible 5.0V-tolerant MX architecture, antifuse program interconnect (non-volatile and secure, no configuration PROM required at power-up), and support for the IEEE 1149.1 JTAG boundary-scan standard on family members. The commercial-grade FPLG84 package is a square 84-lead J-lead chip carrier (package code QCCJ) suited for solder reflow assembly.
The MX family uses a proven 0.45um CMOS antifuse process, delivering deterministic interconnect delays and one-time programmability that eliminates configuration time and improves design security versus SRAM FPGAs. Logic is organized in mux-based combinational modules and sequential modules typical of the Actel MX architecture.
Typical applications include glue logic integration, legacy PLD consolidation, industrial control, telecommunications line cards, and high-reliability single-chip ASIC prototyping where a soldered, non-volatile FPGA is preferred over SRAM-based devices.
Design consideration: because the device is one-time programmable (antifuse), debugging requires the Actel/Microchip Libero design flow and careful pre-programming simulation; dual-rail power sequencing (5V and 3.3V) must also be verified in the power-supply design.

عام استعمالات
A42MX16-FPLG84 کے لیے موزوں ہے 6 ایپلیکیشنs: Legacy PLD Consolidation, Industrial Control Systems, Single-Chip ASIC Alternative, Telecommunications Line Cards, Test and Measurement Fixtures, Aerospace and Defense Legacy Sustainment.
Legacy PLD Consolidation
The MX family's 5V-tolerant architecture makes the A42MX16-FPLG84 ideal for collapsing multiple legacy PAL/GAL/PLD devices into a single antifuse FPGA. Its 24,000 gates and 608 cells provide ample capacity for several mid-size PLD designs, while 72 I/O handles the combined pin count. Because antifuse programming is non-volatile, replacement boards power up instantly with no configuration PROM, matching the behavior of the original discrete PLDs and simplifying qualification of legacy industrial and telecom boards.

Industrial Control Systems
In factory automation and motor-control supervisory boards, the A42MX16-FPLG84 provides deterministic glue logic between microcontrollers, sensors, and actuators. The 62 MHz system frequency is sufficient for address decoding, PWM merging, and interlock logic, and 5V/3.3V dual-supply I/O directly interfaces legacy industrial TTL-level signals without level shifters. Antifuse one-time programming eliminates configuration corruption in electrically noisy environments, a common failure mode of SRAM FPGAs on plants with unstable power.

Single-Chip ASIC Alternative
The MX family is positioned by Microchip as a reliable single-chip ASIC alternative for mid-volume products. The A42MX16-FPLG84's antifuse interconnect delivers deterministic delays and masks design content from competitors, approximating ASIC security at FPGA economics. With 24,000 gates it fits control, interface, and data-path functions that would otherwise require a mask ASIC with high NRE. Designers validate in simulation, then program production devices, avoiding ASIC lead times and minimum-order commitments.

Telecommunications Line Cards
Telecom line cards frequently mix legacy 5V backplane signaling with 3.3V logic; the A42MX16-FPLG84 bridges both domains with its dual 3.3V/5V supply architecture. Its 72 I/O terminate backplane address, data, and control lines, while the 62 MHz system speed covers T1/E1 framing glue and HDLC-style edge handling. Non-volatile antifuse configuration ensures the card is functional immediately at hot-swap insertion, before a host can download bitstreams, improving fault diagnostics.
تجویز کردہ
Test and Measurement Fixtures
Production test fixtures and bed-of-nails interfaces use the A42MX16-FPLG84 as reprogrammable-at-design-time channel multiplexing, address decoding, and pass/fail gating logic. IEEE 1149.1 JTAG boundary-scan support on 42MX devices enables board-level interconnect testing through the same header used for programming. Because the device is one-time programmable, fixture logic can be locked against unauthorized change - valuable for calibrated or certified test stations where configuration integrity must be provable.

Aerospace and Defense Legacy Sustainment
Actel antifuse FPGAs have a long heritage in defense electronics, and the A42MX16-FPLG84 continues sustaining programs that specified MX devices. Non-volatile programming, radiation-tolerant family lineage, and secure configuration make it a fit for ground-based and benign-environment military spares. With 24,000 gates it replicates legacy gate-array and PLD functions without redesign, and Microchip's longevity commitments on mature FPGA families support long-term obsolescence management through last-time-buy planning.

ڈیزائن نوٹس
The A42MX16-FPLG84 requires dual supplies: 5V nominal core (4.75V-5.25V commercial) and 3.3V I/O (3.0V-3.6V) per Microchip USA documentation. Decouple each rail with 0.1uF ceramics at package corners plus 10uF bulk per rail. Verify power-up sequencing against the MX datasheet to avoid latch-up during mixed-rail ramping, especially when the 5V rail is shared with legacy TTL loads.
This is a one-time-programmable antifuse device: a programming error is unrecoverable. Complete full pre-programming simulation in the Microchip Libero/Designer flow, reserve spare I/O in the pin assignment, and order engineering-spare devices before committing production programming. Also note that moving a design between standard and -1 speed grades changes timing; re-run static timing analysis on any swap.
The 84-PLCC (QCCJ) J-lead package needs a square footprint per JEDEC PLCC-84 dimensions; allow J-lead fillets for rework. Keep the programming pins (VPP and related) routed per datasheet recommendations even in normal operation, and place 0.1uF decoupling within 3mm of VCC/GND pairs. Confirm pin-1 index mark orientation - PLCC pin 1 is at the center of one edge, not a corner.
At 0.45um-era edge rates, 5V-tolerant I/O can drive fast edges into legacy buses. Add 22-33 ohm series resistors on long backplane or cable runs to control ringing, and use the device's JTAG (IEEE 1149.1) boundary-scan chain during board bring-up to verify interconnect before functional test.
