Typical Applications
A42MX36-PQG208A is suitable for 6 applications: Legacy 5.0V System Integration, Industrial Control and Automation, PCI Bus Interface Design, Aerospace and Defense Upgrades, Single-Chip ASIC Alternative, Test and Measurement Equipment.
Legacy 5.0V System Integration
The A42MX36-PQG208A natively operates at 5.0V, matching older board-level power rails that modern 3.3V/1.2V FPGAs cannot tolerate without level shifting. Its 54K gates and 176 user I/Os allow consolidating multiple legacy PLDs, PALs, and glue logic into one device, cutting board area and BOM cost. MultiPlex I/O supports 5.0V/3.3V mixed signaling, easing transitions where new peripherals coexist with 5V buses. The one-time-programmable fabric needs no boot flash, improving reliability in long-lifecycle industrial systems.
Recommended
Industrial Control and Automation
In factory automation and motor-control backplanes, the A42MX36-PQG208A provides deterministic, one-time-programmable logic with 116 MHz capability and robust 5.0V noise margins suited to electrically harsh environments. Its automotive/military temperature screening ensures dependable operation beyond commercial limits. The low-power mode reduces dissipation in always-on control nodes. PCI v2.1 programmable compliance also allows direct interface to industrial PC backplanes without external bridge devices.
Recommended
PCI Bus Interface Design
The MX family is fully compliant with the PCI Local Bus Specification version 2.1, with programmable PCI support delivered by the MultiPlex I/O structure at both 5.0V and 3.3V signaling levels. Designers can implement PCI target or master interfaces directly inside the 54K-gate fabric alongside custom application logic, eliminating a dedicated PCI ASSP. The 116 MHz maximum clock capability covers the 33 MHz PCI clock domain with ample margin for internal logic.
Recommended
Aerospace and Defense Upgrades
For defense programs maintaining 5V-era platforms, the A42MX36 offers CQ208 ceramic packages screened to MIL-STD-883 levels, and the plastic PQ208 is pin-compatible with CQ208, allowing prototype on plastic and conversion to ceramic without PCB rework. The antifuse fabric is immune to configuration-memory upset, an advantage over SRAM FPGAs in radiation environments. The PQG208A automotive/military temperature screening supports ground-based and avionic legacy refresh applications.
Recommended
Single-Chip ASIC Alternative
Microchip positions MX FPGAs as reliable, single-chip ASIC alternatives for high-volume products. Compared with an ASIC's NRE and long lead times, the A42MX36-PQG208A provides instant programmability, field updates via device replacement, and zero mask costs at moderate volumes. Its 54K-gate capacity suits protocol glue, bus bridging, and control datapaths. One-time programming also protects the design from cloning because the configuration cannot be read back.
Recommended
Test and Measurement Equipment
Bench instruments and ATE often retain 5V subsystems where the A42MX36-PQG208A interfaces directly with legacy ADCs, drivers, and backplanes without translation devices. Its 176 I/Os handle wide parallel data buses for timing and control sequencing, and the 116 MHz fabric clock supports fast state machines. One-time-programmable configuration guarantees the instrument powers up instantly with no configuration latency, which matters in rack systems with strict boot-time requirements.

Key Differentiators
- Automotive temperature screening (vs A42MX36-PQG208I)
- Full 54K-gate density in PQFP-208 (vs A42MX24-3PQG208I)
- No configuration flash required (vs SRAM-based FPGA vendors)
Design Notes
The A42MX36 requires a clean 5.0V supply. Provide bulk and 0.1uF ceramic decoupling at each VCC/GND pair on the 208-pin PQFP, and budget current per the Libero SoC power estimator for your design. When driving 3.3V I/O banks via MultiPlex I/O, verify bank voltage assignments so no 3.3V-only device receives 5V signaling.
MX devices are one-time programmable (antifuse): a design error cannot be corrected in-system. Complete full simulation and, ideally, prototype on the pin-compatible CQ208/PQ208 pair before final programming. Also note speed grade suffixes affect timing closure - re-run static timing when switching between A, 1, and MX39 grade devices.
The 208-pin PQFP has 0.5 mm-pitch leads; use a land pattern per the datasheet DS2316 package drawing with no-clean flux to avoid bridging. Keep PCI and high-speed clock traces impedance-controlled and short; distribute ground returns under the device with a solid plane on layer 2 for signal integrity at the 116 MHz internal clock rates.
Compliance Information
Distributor listing (PCB Electronics Supply Chain) indicates LEAD FREE for A42MX36-PQG208A. AEC-Q100 qualification not stated in provided data; MX devices are specified for automotive temperature ranges but formal AEC-Q100 status is unknown.
