- Industrial temperature range (vs A42MX16-PLG84)
Design Notes
The A42MX16-PLG84A requires a 5.0V supply. Ensure adequate decoupling with 0.1uF and 10uF capacitors placed close to each VCC and GND pin. The FPGA's power consumption depends on logic utilization and toggle rate; estimate using Microchip's power calculator. For high-speed designs, consider a dedicated power plane to minimize noise.
The 84-pin PLCC package has J-leads, which require a specific footprint. Use the recommended land pattern from the datasheet. For hand-soldering, a PLCC socket is recommended for prototyping. Ensure proper thermal relief for the center pad if present. Follow IPC-7351 guidelines for pad dimensions.
Do not exceed the absolute maximum supply voltage of 5.5V. Ensure all I/O pins are not driven above VCC. The FPGA's configuration is non-volatile, but verify the programming voltage and timing. For JTAG programming, use a standard 4-wire interface and ensure proper pull-up resistors on TMS and TDI.
