A42MX16-PQ100 - MX FPGA 24K Gates 100-PQFP | Microchip
MPN: A42MX16-PQ100 ✓ نشطA42MX16-PQ100 نظرة عامة
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.

التطبيقات النموذجية
A42MX16-PQ100 مناسب لـ 6 التطبيقs: Industrial Control System Upgrades, Legacy Board Redesign / Obsolete PLD Consolidation, High-Volume Embedded Control, Glueless Bus Interfacing, Automotive Control Modules, Test and Measurement Fixtures.
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.
موصى به
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.
موصى به
Glueless Bus Interfacing
The A42MX16-PQ100 implements glueless bus interfaces between microprocessors, memories, and peripherals using its 83 user-programmable I/O and fast wide-decode circuitry. Wide decode structures in the MX fabric generate chip-select and address-decode outputs with minimal propagation delay, and the 5V-tolerant I/O banks connect directly to 5V microprocessor buses such as those on mature 8051, 68k, or PowerPC platforms. The 100-PQFP's 0.5mm-pitch leads keep signal integrity manageable for 103 MHz-class bus timing while remaining hand-solderable for prototyping.
موصى به
Automotive Control Modules
The 42MX family includes automotive FPGA variants, and the A42MX16's nonvolatile single-chip fabric addresses automotive needs for instant-on logic, configuration integrity, and supply-chain longevity. In body control, powertrain adjunct, and instrumentation modules, the FPGA consolidates legacy PAL/PLD logic that was never migrated to modern CMOS, running from the vehicle's regulated 5V rail. Engineers should select the automotive-qualified ordering variant and validate temperature-range requirements per the 40MX/42MX automotive family datasheet before production release.
موصى به
Test and Measurement Fixtures
Bench and production test fixtures benefit from the A42MX16-PQ100's one-time-programmable, tamper-resistant configuration: the test logic cannot be accidentally or maliciously altered after programming, ensuring repeatable fixture behavior across production sites. Dual-port SRAM captures stimulus/response data between the device-under-test and the host controller, while 83 I/O provide broad parallel access to test points. The PQFP package and 5V I/O tolerance allow direct interfacing with legacy 5V TTL test hardware common in mature production lines.

ملاحظات التصميم
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.
