A42MX16-1PQG208I 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and programmable interconnects that the designer configures after manufacturing. Within the power management hierarchy of programmable logic, FPGAs sit above CPLDs in density and flexibility, and the MX family is specifically positioned as a reliable, single-chip ASIC alternative for high-volume, cost-sensitive designs integrating legacy PLD functionality.
Key features include an efficient, flexible 5.0V-tolerant architecture, 200 MHz on-chip operation with 6.1 ns clock-to-output performance, and PCI Local Bus Specification (version 2.1) compliance. The device uses 0.45 um CMOS process technology and supports system-level features in larger family members such as IEEE 1149.1 (JTAG) boundary scan testing and fast wide-decode modules.
The act-1 style logic architecture provides predictable routing delays, making the MX family attractive for designs migrating from discrete PAL/GAL/PLD devices into a single low-cost FPGA while maintaining 5V compatibility required by legacy industrial backplanes.
Typical applications include legacy industrial control systems, 5V PCI interfaces, MIL/COTS heritage system refreshes, glue logic consolidation, and replacement of obsolete multi-PLD designs. Its 5V I/O tolerance eliminates level-shifting when interfacing with older TTL/5V CMOS peripherals.
Design consideration: plan power-up sequencing and verify I/O bank loading against the 208-pin PQFP thermal characteristics; maximum junction temperature is 150 C per the 40MX/42MX families datasheet (DS2136).

主な用途
A42MX16-1PQG208I の用途: 6 件s: 5V PCI Bus Interfaces, Legacy Industrial Control Systems, PLD Consolidation / Glue Logic, Defense / Heritage System Refresh, Test and Measurement Equipment, ASIC Prototyping and Low-Volume Bridge.
5V PCI Bus Interfaces
The A42MX16 fits 5V PCI interface designs because 42MX devices are fully compliant with the PCI Local Bus Specification version 2.1, delivering 200 MHz on-chip operation and 6.1 ns clock-to-output performance per DS2136. The native 5.0V-tolerant I/O architecture connects directly to legacy 5V PCI backplanes without level translators, reducing BOM cost and failure points. Implement the PCI state machine in the 608-CLB fabric with margin, since the 119 MHz/198 MHz system clock support comfortably exceeds the 33/66 MHz PCI clock domains.
おすすめ
Legacy Industrial Control Systems
Industrial retrofits benefit from the A42MX16's 5V-tolerant architecture, which interfaces directly with older TTL and 5V CMOS PLC I/O modules without level shifting. The industrial temperature grade (-40C to +85C) and 0.45 um CMOS process provide proven reliability in electrically noisy factory environments. As a single-chip ASIC alternative per Microchip's MX positioning, it consolidates multiple legacy PAL/GAL/PLD devices into one 24K-gate device, cutting board area and inventory while preserving proven logic functionality.
おすすめ
PLD Consolidation / Glue Logic
The MX family was explicitly designed as a platform for integrating legacy PLDs into a single low-cost device, per the Microchip A42MX16 product page. With 24,000 gates and 1,232 logic cells, one A42MX16 typically replaces several 22V10-class PLDs plus discrete decoding logic. Predictable act-1 routing delays simplify timing closure when migrating schematics from fixed-delay PAL devices. The result is fewer line items, lower assembly cost, and one programming file instead of multiple device chains.
おすすめ
Defense / Heritage System Refresh
Microsemi (now Microchip) MX FPGAs have a long heritage in defense and aerospace program sustainment, where long-lifecycle supply and 5V interface compatibility matter more than process node. The A42MX16 in industrial grade supports obsolescence-driven board redesigns of 1990s-era avionics, telemetry, and test equipment. Military (M) and other temperature grades exist within the family, letting designers match grade to program requirements while reusing one toolchain and one logic design across board variants.
おすすめ
Test and Measurement Equipment
Bench and rack instrumentation with 5V digital backplanes use the A42MX16 for trigger logic, counter/timer functions, and bus interfacing. The 6.1 ns clock-to-output and 198 MHz toggle capability support fast counter chains, while PCI v2.1 compliance enables standard instrumentation bus cards. The 208-pin PQFP offers generous I/O for multi-channel stimulus/response front ends. Industrial temperature rating also suits portable instruments used outdoors across the full -40C to +85C ambient range.
おすすめ
ASIC Prototyping and Low-Volume Bridge
As a single-chip ASIC alternative, the A42MX16 serves as a prototype or bridge device for 24K-gate ASICs where mask costs are unjustified. The 0.45 um CMOS fabric with deterministic routing gives predictable timing during RTL or schematic verification, and the dual 3.3V/5V supplies emulate legacy ASIC I/O environments. For low-volume production, the same FPGA can ship in the product, deferring or eliminating ASIC NRE entirely - a core MX family value proposition for high-mix, low-volume manufacturers.

主な差別化要因
- Native 5V-tolerant architecture （vs A42MX24-1PQG208M)
- PCI Local Bus v2.1 compliance at 6.1 ns clock-to-out （vs A42MX16-PQG208I)
- Same-die package flexibility within 42MX16 （vs A42MX16-1PQG100)
設計ノート
The A42MX16 uses a dual 3.3V/5V supply scheme on the 0.45 um CMOS process. Verify per-pin supply assignments in DS2136 and decouple each VCC pin pair with 0.1 uF ceramic capacitors placed within 5 mm, plus bulk 10 uF per rail. Exceeding the 150 C maximum junction temperature voids reliability targets; compute dissipation from actual I/O loading since PQFP theta-JA dominates the budget in still air.
With 5V-tolerant I/O switching on a PQFP with 0.5 mm pitch, ground bounce on simultaneously switching outputs can exceed TTL noise margins if return paths are fragmented. Assign bank outputs to interleave GND pins, limit simultaneously switching output groups, and use series 22-33 ohm termination on fast edges driving long backplane traces, especially for PCI v2.1 compliant designs.
The 42MX16 does not include IEEE 1149.1 JTAG boundary scan (that feature belongs to 42MX24/42MX36), so plan board-level test with bed-of-nails or functional vectors rather than assuming chain access. Also note the -1 speed grade vs faster grades differ in timing models - always run static timing with the exact order code (A42MX16-1PQG208I) selected in Libero/design tools before sign-off.
