A42MX16-PQ100 概覽

The Microchip Technology (formerly Actel/Microsemi) A42MX16-PQ100 is a member of the 42MX antifuse FPGA family, delivering approximately 24,000 system gates with 608 logic cells in a 100-pin PQFP (100-BQFP) surface-mount package with 83 user-programmable I/O pins. It operates from dual 3.3V/5.0V supply rails with system performance of 103 MHz (172 MHz toggle).

A field-programmable gate array (FPGA) is an integrated circuit that can be configured by the designer after manufacturing, sitting within the programmable logic hierarchy between fixed-function ASICs and CPLDs. The MX family is distinctive because it uses Actel antifuse interconnect technology, which is nonvolatile and one-time programmable - the configuration is retained with power off and requires no external boot flash, providing a single-chip ASIC alternative for high-volume, cost-sensitive designs.

Key features include up to 2.5 kbits of configurable dual-port SRAM, fast wide-decode circuitry, 100% resource utilization with 100% pin locking, and deterministic routing based on a 0.45um CMOS process. The 5.0V-tolerant architecture makes it especially suited to integrating legacy 5V PLD designs into a single low-cost device, and an automotive variant of the 42MX family is available.

Typical applications include industrial control system upgrades, legacy board redesigns, glueless bus interfacing, and high-volume embedded control where single-chip nonvolatile programmable logic reduces board complexity and BOM cost.

Design consideration: because antifuse devices are one-time programmable, complete functional simulation and timing verification with Libero/Microsemi design tools is mandatory before programming production units.

🏭

Industrial Control System Upgrades

The A42MX16-PQ100 fits industrial control upgrades where legacy 5V PLD and ASIC designs must be consolidated without redesigning 5V bus infrastructure. Its dual 3.3V/5V supply operation and 5V-tolerant MX architecture allow direct interfacing with older TTL-level I/O, while 608 logic cells and fast wide-decode circuitry implement address decoders, sequencers, and bus controllers on a single chip. Because the antifuse configuration is nonvolatile, control logic initializes instantly at power-up with no configuration device, maximizing uptime in factory equipment and reducing board complexity for legacy system upgrades.

🔧

Legacy Board Redesign / Obsolete PLD Consolidation

For legacy board redesigns, the A42MX16-PQ100 replaces multiple discrete 22V10-class PLDs, PALs, and glue logic with a single low-cost antifuse FPGA. Microchip positions the MX family specifically as a platform for integrating legacy PLDs into one device, and with 100% resource utilization and 100% pin locking support, designers can lock critical pin assignments early and fill remaining fabric without routing penalties. The one-time-programmable fabric eliminates the boot-flash IC and its failure modes, cutting BOM count and improving reliability in mature products with long field service lives.

🖥️

High-Volume Embedded Control

In high-volume embedded control products, the A42MX16-PQ100 delivers ASIC-like integration without ASIC NRE costs. The 0.45um antifuse process and PQFP packaging keep unit cost low at volume, while deterministic routing gives predictable timing across production lots - important for designs at 103 MHz system performance. The 2.5 kbits of configurable dual-port SRAM implement FIFOs and scratch buffers between a microcontroller and peripherals. Because configuration is fixed at programming, field-failure analysis is simpler and there is no risk of bitstream corruption in electrically noisy environments.

推薦產品摘要

What is the A42MX16-PQ100?

The A42MX16-PQ100 is a Microchip Technology (Actel/Microsemi) MX-family antifuse FPGA with 24,000 system gates, 608 logic cells, and 83 user I/O in a 100-pin PQFP package. It operates at 3.3V/5V with 103 MHz system performance and features 2.5 kbits of configurable dual-port SRAM. Its nonvolatile antifuse fabric makes it a single-chip ASIC alternative for legacy and high-volume designs.

Where can I download the A42MX16-PQ100 datasheet PDF?

The A42MX16-PQ100 datasheet is available from the official Microchip product page at microchip.com/en-us/product/a42mx16 under the 40MX and 42MX FPGA Families document. Distributor sites such as DigiKey, Mouser, Octopart, and FindIC (9828KB PDF, published 2015-08-21) also host the datasheet PDF for direct download along with pinout and packaging information.

What is the best drop-in replacement for A42MX16-PQ100?

Within the same 100-PQFP package and MX family, the closest same-brand options are other A42MX16 speed-grade and temperature-grade variants such as the A42MX16-1PQ100I (industrial temperature). There is no true cross-brand pin-compatible drop-in for Actel antifuse FPGAs, because the antifuse architecture and pinout are proprietary. For EOL risk, contact Microchip for last-time-buy and lifetime-buy programs.

What is the difference between A42MX16 and A42MX24?

Both belong to the 42MX antifuse FPGA family, but the A42MX24 offers a larger gate count and more logic resources than the A42MX16 (24K gates, 608 cells). Larger 42MX members such as the A42MX24-PQ160I and A42MX36 come in bigger packages like PQ160 or PL84. Designers migrating upward should verify package footprint and I/O count, as PQ100 and PQ160 are not footprint-compatible.

Is A42MX16-PQ100 suitable for automotive applications?

Yes - the 42MX family includes an automotive FPGA variant per the Microchip datasheet covering the 40MX and 42MX Automotive FPGA Families. The single-chip nonvolatile antifuse fabric is attractive for automotive systems because it requires no configuration device and resists configuration corruption. Verify the automotive-qualified suffix variant and its AEC qualification status with Microchip before design-in.

How many I/O pins does the A42MX16-PQ100 have?

The A42MX16-PQ100 provides 83 user-programmable I/O pins on its 100-pin PQFP package. According to DigiKey's listing, the device is described as an MX Field Programmable Gate Array IC with 83 I/O in 100-BQFP. The 42MX family supports up to 202 user I/O on its largest packages, but this PQ100 variant is limited to 83.

Is A42MX16-PQ100 the same as A42MX16PQ100?

Yes - A42MX16PQ100 and A42MX16-PQ100 refer to the same Microchip (Actel/Microsemi) MX FPGA device; the hyphen is part of the official manufacturer part numbering and some distributors list it without the hyphen. Both designate the 24K-gate 42MX FPGA in the 100-PQFP package with 83 I/O. Always verify the exact speed/temp ordering code when purchasing.

What are the key specifications of A42MX16-PQ100 that engineers should know?

Key specifications: 42MX family antifuse FPGA; 24,000 system gates; 608 logic cells; 83 user I/O; 103 MHz system frequency (172 MHz toggle); 0.45um CMOS process; dual 3.3V/5V supply; 2.5 kbits configurable dual-port SRAM; 100-pin PQFP package; one-time-programmable nonvolatile configuration with 100% pin locking and 100% resource utilization. Source: Microchip/Microsemi A42MX16 datasheet and distributor listings.

Why choose an antifuse FPGA like the A42MX16 over SRAM-based FPGAs?

Antifuse FPGAs are nonvolatile and one-time programmable: configuration survives power-off with no external boot flash, and there is no configuration bitstream to corrupt or intercept. This simplifies BOM, improves security, and suits high-volume legacy 5V integration. The trade-off is that a programmed unit cannot be reconfigured - designs must be fully verified before programming, and field firmware updates are impossible.

What is the price of A42MX16-PQ100?

Exact per-unit pricing varies by distributor, quantity, and speed/temp ordering code; Octopart aggregates bulk discounts from 8 distributors for this part. As of 2026-08-30, obtain a real-time quote on XAIPART, DigiKey, Mouser, or Octopart. As a mature legacy Actel product, pricing and stock fluctuate - request quotes for volume purchases and confirm lead times.

Where can I buy A42MX16-PQ100 online?

The A42MX16-PQ100 can be purchased from major distributors including DigiKey, Mouser, and multiple global brokers aggregated on Octopart (8 distributors listed). XAIPART also offers direct quoting and stock checks for this Microchip MX FPGA. Because this is a mature device, verify stock freshness and request certificates of authenticity when sourcing from secondary distributors.

What is the lead time for A42MX16-PQ100?

Lead time depends on distributor stock and Microchip factory scheduling; DigiKey frequently shows ships-today stock for this part, while broker channels may quote multi-week lead times. For production volumes, contact Microchip or MicrochipDirect for factory lead-time commitments, and consider a lifetime buy given the legacy status of the 0.45um antifuse process family.

What software do I need to program the A42MX16-PQ100?

Design entry, place-and-route, and programming of MX-family antifuse FPGAs use Microchip's (formerly Microsemi/Actel) Libero SoC design suite, which supersedes the legacy Actel Designer toolchain. Because antifuse devices are one-time programmable, complete simulation and timing closure in Libero is essential before generating the programming file for production devices.

What is a good equivalent for the A42MX16-PQ100 from another brand?

There is no cross-brand pin-compatible equivalent for the A42MX16-PQ100 - Actel antifuse FPGA pinouts are proprietary, so vendors such as Xilinx, Altera (Intel), or Lattice have no drop-in match in a 100-PQFP footprint. A functional migration would require PCB redesign to a modern SRAM-based FPGA plus an external configuration device, trading away the MX family's nonvolatile single-chip advantage.

選型指南

Choose the A42MX16-PQ100 when you need roughly 24K gates of nonvolatile programmable logic in a compact 100-PQFP with 83 I/O and direct 5V/3.3V interface compatibility - typical for legacy PLD consolidation, industrial control, and high-volume glueless bus interfacing. Choose the A42MX16-1PQ100I if your environment requires industrial temperature range; choose the A42MX16-2PQ100 if timing margins at 103 MHz are tight. If your design exceeds 24K gates, migrate to A42MX24 or A42MX36 family members, but note these come in PL84/PQ160/PQG208 packages requiring PCB rework. There is no cross-brand pin-compatible alternative; migrating to SRAM FPGAs means a full board redesign plus external configuration memory. Verify ordering codes carefully - speed grade and temperature suffix determine availability and lead time.

設計說明

Antifuse FPGAs are one-time programmable. Complete functional simulation, static timing analysis, and pin-lock verification in Microchip Libero SoC (or legacy Actel Designer) before programming production units. A design bug discovered after programming cannot be patched - replacement parts and reprogramming are required, which is costly in volume production. Maintain a locked, revision-controlled programming file tied to board revision.

The device operates from dual 3.3V and 5.0V rails; sequence and decouple each rail locally with 0.1uF ceramic capacitors per power pin plus bulk capacitance at the board level. Verify total supply current against datasheet estimates for your design utilization - antifuse MX devices have no configuration inrush current (unlike SRAM FPGAs), but core and I/O switching current scales with clock activity at 103 MHz.

The 100-PQFP has fine-pitch leads requiring accurate land-pattern layout per the Microchip packaging drawing and careful reflow profiling; inspect for solder bridging on the 0.65mm-class pitch. Keep unused I/O configured with defined logic states or tristate with pull resistors per the 42MX datasheet I/O guidelines to prevent floating-node noise and excess current draw.
