A42MX16-1PQG208 Обзор
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that the designer configures after manufacturing. Within the programmable logic hierarchy, the A42MX16 sits as a mid-density member of the 42MX family (which spans up to the A42MX36), above the 40MX series, and serves as an integration platform for consolidating legacy PLDs, glue logic, and ASIC prototypes into one low-cost device.
Key features include dual 3.3V/5V supply operation for easy integration into mixed-voltage systems, speed grade -1 timing supporting internal performance up to 119MHz/198MHz per family datasheet figures, IEEE 1149.1 JTAG boundary-scan testing on the family, and wide temperature availability across commercial, industrial, automotive, and military ranges. The PQ208 plastic package is pin-compatible with the CQ208 ceramic package, enabling straightforward prototyping-to-production conversion and ceramic screening to MIL-STD-883 on larger family members.
Technically, the MX architecture combines combinational and sequential logic modules with dedicated routing, programmed via antifuse-based configuration that is inherently non-volatile and secure against readback - unlike SRAM FPGAs, no external configuration PROM is required at power-up, reducing BOM cost and improving system boot behavior.
Typical applications include legacy PLD consolidation, ASIC prototyping, industrial control, aerospace and defense subsystems (with ceramic package options), and communication equipment requiring 5V-compatible I/O.
Design consideration: the MX family is mature; verify lifecycle status and plan a second-source or migration strategy for new designs, and confirm JTAG programming fixture compatibility with Microchip FlashPro-style tooling for the antifuse device.

Типичное применение
A42MX16-1PQG208 подходит для 6 применениеs: Legacy PLD Consolidation, ASIC Prototyping, Industrial Control Systems, Aerospace and Defense, Communication Equipment, Test and Measurement Fixtures.
Legacy PLD Consolidation
The MX family is explicitly positioned by Microchip as a platform for integrating legacy PLDs into a single low-cost device. With 24,000 system gates, 608 logic cells, and 140 user I/O, the A42MX16-1PQG208 can absorb multiple 22V10-class PLDs and glue logic into one 3.3V/5V-tolerant package. Antifuse configuration means no external configuration PROM and instant power-up, simplifying board bring-up compared to SRAM FPGA designs.
Рекомендуется
ASIC Prototyping
MX FPGAs offer a reliable single-chip ASIC alternative for prototyping and low-to-mid-volume production. The 0.45um antifuse process and deterministic routing suit gate-array-style flows, and Microchip provides conversion paths from FPGA prototypes to structured ASIC derivatives. The 140 I/O and 119MHz/198MHz internal performance cover many legacy ASIC interface requirements while the PQ208 footprint transitions to ceramic CQ208 for qualification builds.
Рекомендуется
Industrial Control Systems
In industrial controllers and motor-drive interface cards, the A42MX16-1PQG208 provides 5V-tolerant I/O that directly connects to legacy sensors, relays, and PLC backplanes without level shifters. Speed grade -1 timing at 119MHz/198MHz is ample for state machines and bus interface logic. Industrial-temperature sibling A42MX16-1PQG208I is a drop-in for harsh-environment builds on the identical PCB.
Рекомендуется
Aerospace and Defense
The MX family is fully tested over automotive and military temperature ranges, and the A42MX36 is available in CQ208/CQ256 ceramic packages screened to MIL-STD-883. Designers prototype on the plastic PQ208 and convert to ceramic for flight builds because PQ208 and CQ208 are pin-compatible. The antifuse configuration is immune to configuration upsets from radiation-induced readback and offers secure, non-volatile storage valued in defense programs.
Рекомендуется
Communication Equipment
Line cards and backplane interface logic in telecom and datacom equipment benefit from the A42MX16-1PQG208's 140 user I/O and mixed 3.3V/5V operation, bridging 5V legacy line interfaces to 3.3V logic domains. Deterministic antifuse routing supports predictable timing for framing, multiplexing, and protocol glue logic, while non-volatile configuration ensures the link is immediately operational at power-up with no boot delay.
Рекомендуется
Test and Measurement Fixtures
Production test fixtures and JTAG-based board test setups use the A42MX16-1PQG208 to implement scan controllers, pattern generators, and bus capture logic. Family IEEE 1149.1 boundary-scan support enables board-level interconnect test integration, and the -1 speed grade delivers adequate 119MHz-class performance for fixture-side logic. Its 208-pin PQFP provides abundant I/O for contacting multi-connector boards under test.

Ключевые отличия
- Non-volatile antifuse configuration - no boot PROM (против SRAM FPGAs (e.g., Xilinx/Altera equivalents))
- Pin-compatible density scaling in PQ208 (против A42MX24-1PQG208I / A42MX36-1PQG208)
- Dual 3.3V/5V I/O operation (против Modern low-voltage FPGAs)
Заметки по проектированию
The MX architecture supports 3.3V and 5V operation. Decouple VDD pins with 0.1uF ceramic capacitors at each supply pin plus bulk 10uF near the device. Because antifuse devices draw no configuration current at power-up, inrush is minimal - but verify I/O bank currents when driving 5V legacy loads at 140 I/O to stay within package power limits.
The PQFP-208 has 0.5mm-pitch leads; use a 0.65mm-center footprint per the DS2316 mechanical drawing and verify with your assembler. Since PQ208 is pin-compatible with CQ208 ceramic, design the footprint once to allow prototype-to-production and high-reliability conversion without PCB spin.
Antifuse programming is one-time: a design change requires a new physical device, so reserve engineering spare gates and route spare I/O to test points before committing. Also note IEEE 1149.1 JTAG detail in DS2316 is explicitly described for 42MX24/42MX36 - validate the A42MX16 scan chain in your test plan rather than assuming identical compliance.
