A42MX16-PQG208I Übersicht
A field-programmable gate array (FPGA) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that designers configure in the field via hardware description languages such as VHDL or Verilog. Within the power-management hierarchy of system logic, FPGAs sit above fixed-function ASICs in flexibility and below CPLDs in simplicity for small designs, serving as a reliable single-chip ASIC alternative for glue logic, bus interfacing, and control-plane integration.
Key features of the A42MX16 include a dual 3.3 V/5 V supply architecture that eases integration into legacy 5 V systems, 608 configurable logic cells organized in the Actel MX combinatorial-and-sequential module structure, and 140 bidirectional user I/O pins on the 208-pin body. The MX family is a proven high-volume platform targeted at consolidating legacy PLDs and small ASICs into one low-cost, antifuse-programmable device.
The 42MX architecture delivers dependable deterministic routing with no configuration-memory volatility, and family documentation notes full compliance with the PCI Local Bus Specification (version 2.1) together with up to 200 MHz on-chip operation and 6.1 ns clock-to-output performance in family members; higher-density 42MX24/42MX36 devices add IEEE 1149.1 (JTAG) boundary scan testing and fast wide-decode modules.
Typical applications include industrial automation controllers, telecommunications line cards, legacy 5 V system upgrades, and embedded control systems where a proven single-chip ASIC replacement reduces bill-of-material cost and obsolescence risk.
When designing with this device, verify power sequencing of the 3.3 V core and 5 V I/O domains, and confirm that the industrial temperature variant (suffix I) matches your environmental requirements, since commercial and automotive grade variants of the same die exist.

Typische Anwendungen
A42MX16-PQG208I ist geeignet für 6 Anwendungs: Industrial Automation and Control, Legacy 5 V System Consolidation, Telecommunications Line Cards, Embedded Control Systems, Single-Chip ASIC Alternative / NRE Avoidance, Security and Surveillance Equipment.
Industrial Automation and Control
The A42MX16-PQG208I fits industrial automation controllers where deterministic, non-volatile logic must survive power interruptions and harsh temperatures. Its -40C to +85C industrial rating and antifuse configuration mean no configuration flash to corrupt and no configuration device to source, a common failure point in SRAM FPGAs on factory floors. With 24,000 system gates, 608 logic cells, and 140 user I/O in a 208-pin PQFP, it absorbs glue logic, sensor interfaces, and sequencing previously spread across multiple PLDs. Placed on a 3.3 V/5 V dual-rail board, it directly bridges legacy 5 V TTL peripherals with modern 3.3 V logic, eliminating level-shifters and reducing BOM cost in brownfield machine retrofits.

Legacy 5 V System Consolidation
The dual 3.3 V/5 V supply architecture makes the A42MX16-PQG208I an ideal consolidation vehicle for legacy 5 V backplane systems still running TTL-compatible peripherals. According to Microchip's MX family positioning, MX is an ideal platform for integrating legacy PLDs into a single, low-cost device in high-volume production. Designers replace banks of 22V10 GALs, PALs, and SSI/MSI glue chips with one 24,000-gate antifuse device, gaining reliability and shrinking board area without redesigning the 5 V environment. The 140 user I/O on the 208-pin PQFP provide the pin budget those legacy devices collectively consumed, and the non-volatile antifuse fabric powers up instantly with no configuration load time.
Empfohlen
Telecommunications Line Cards
Telecom line cards benefit from the A42MX16-PQG208I's deterministic routing and single-chip ASIC-alternative economics. Distributor references (Baidu B2B, FPGAkey) identify telecommunications as a primary deployment domain for this part, where it implements framing logic, backplane interface glue, and supervisory state machines. The 42MX family's PCI Local Bus Specification version 2.1 compliance enables direct host-bus interfacing, and family performance up to 200 MHz on-chip operation with 6.1 ns clock-to-output supports line-card timing budgets. The industrial temperature range covers central-office environments, and the antifuse fabric introduces no configuration-read latency at card power-up, critical for hot-swap slot architectures.
Empfohlen
Embedded Control Systems
In embedded control systems, the A42MX16-PQG208I serves as a configurable co-processor beside a microcontroller, offloading time-critical state machines, PWM generation, and parallel bus decoding. The 608-cell MX fabric implements combinatorial and sequential modules with predictable timing, and the dual-supply design lets it sit between a 5 V sensor domain and a 3.3 V MCU domain as a protocol bridge. With 140 user I/O, one device can terminate multiple parallel peripherals simultaneously. Recommended companion MCUs such as the MSP430FR5994 provide supervisory intelligence while the FPGA guarantees hard-real-time response that software cannot, and the industrial -40C to +85C rating suits unconditioned enclosures.
Empfohlen
Single-Chip ASIC Alternative / NRE Avoidance
Microchip positions the MX family explicitly as a reliable, single-chip ASIC alternative for high-volume products where ASIC NRE and lead time are unacceptable. The A42MX16-PQG208I delivers 24,000 usable system gates of fixed, verified fabric - designers avoid mask-set costs, spin iterations, and minimum-order exposure while retaining deterministic timing and instant-on antifuse startup that ASIC-like products require. For volumes where a 0.45 um 24K design would justify an ASIC economically, the MX device removes schedule risk instead. The 208-pin PQFP is a mature, low-cost assembly package compatible with standard surface-mount lines, further reducing total deployed cost versus custom packaged silicon.
Empfohlen
Security and Surveillance Equipment
Security and surveillance hardware uses the A42MX16-PQG208I for camera control glue logic, sensor timing generation, and alarm-state machines where instant-on operation matters. The antifuse configuration means the device is functional within nanoseconds of power application - no configuration image to load and no window during which a surveillance node is blind. The 140 user I/O interface CCD/CIS sensor timing, pan-tilt actuators, and legacy 5 V alarm loops on one chip, and the industrial temperature rating covers outdoor enclosures from -40C to +85C. Deterministic single-event routing also avoids the configuration-bitflip concerns associated with SRAM FPGAs in always-on remote installations.

Wichtigste Unterscheidungsmerkmale
- Lowest-cost 208-pin PQFP entry point in the 42MX family (vs. A42MX36-PQG208I)
- Industrial temperature rating in the identical footprint (vs. A42MX16-PQG208A)
- Instant-on antifuse configuration (vs. A42MX24-1PQG208I)
Designhinweise
The A42MX16-PQG208I requires both 3.3 V and 5 V supplies per the 42MX family datasheet. Sequence the rails according to the datasheet power-up specification and decouple each supply pin with 0.1 uF ceramics placed within 2 mm of the pin, plus bulk capacitance near the package. Estimated: at moderate utilization of a 24K-gate 0.45 um antifuse fabric, core current is typically tens of milliamps, but verify with the Microchip Libero/power tools for your actual design rather than relying on estimates.
The 208-pin PQFP has 0.5 mm-pitch leads requiring a solder-mask-defined land pattern per the manufacturer package drawing. Include thermal relief vias under the die area where the board allows, and keep high-fanout FPGA I/O traces short with controlled impedance when driving backplane signals. The PQFP gull-wing leads are mechanically less forgiving than BGA/CSP packages, so specify an inspection-friendly stencil and consider X-ray sampling on first-article builds to confirm lead coplanarity reflow results.
Do not confuse temperature suffixes: the I suffix is industrial (-40C to +85C) while suffix A and M denote automotive and military grades. Second, note that JTAG boundary scan (IEEE 1149.1) is only available on 42MX24/42MX36 devices - if your test plan depends on boundary scan, the A42MX16 will not meet it; select A42MX24-1PQG208I instead. Finally, antifuse devices are one-time programmable: reserve spare gates and verify the design fully in simulation before programming production devices.
