Design Notes
The A42MX16-PG176B operates from a 5.0 V supply. Ensure that all VCC pins (141, 143, 145, 147, 149, 151, 153, 155, 157, 159, 161, 163, 165, 167, 169, 171, 173, 175) are connected to a clean 5.0 V rail with adequate decoupling. Place 0.1 uF ceramic capacitors close to each VCC pin and a 10 uF bulk capacitor near the device. The total current consumption depends on the design's logic utilization and toggle rate; estimate based on the datasheet's power consumption tables. For high-speed designs, use a low-impedance power plane to minimize voltage droop.
The A42MX16-PG176B is a ceramic CPGA package with good thermal conductivity. However, for high-density designs with high toggle rates, power dissipation can be significant. Estimate the power consumption using the datasheet's power estimation formulas, then calculate the junction temperature using the package's thermal resistance (theta_JA). Ensure that the junction temperature stays within the specified operating range. For military temperature grade, the range is typically -55Β°C to +125Β°C. If necessary, use a heatsink or forced airflow to maintain safe temperatures.
The 176-pin CPGA package requires a socket or through-hole soldering. When designing the PCB, ensure that the hole sizes and pad patterns match the package dimensions. For high-reliability applications, consider using a socket to allow easy replacement. Route all I/O signals with controlled impedance if they interface with high-speed buses. Provide a solid ground plane beneath the device to reduce noise. Follow the layout guidelines in the datasheet for decoupling capacitor placement and power plane routing.
Compliance Information
