Design Notes
The A42MX16-1PLG84M supports dual supply voltages of 3.3V and 5V. Ensure that both VCC pins are connected to the appropriate supply rails and that decoupling capacitors (0.1uF and 10uF) are placed close to each VCC pin. The device can operate with either supply, but mixing 3.3V and 5V I/O requires careful consideration of I/O standards. For 5V operation, ensure the supply is within 4.75V to 5.25V. For 3.3V operation, use 3.0V to 3.6V. Proper power sequencing is not critical, but it is recommended to ramp both supplies simultaneously to avoid latch-up.
For the 84-PLCC package, ensure the PCB footprint matches the J-Lead configuration. Use a thermal pad or vias under the package to improve heat dissipation if power dissipation is high. Route all I/O traces with controlled impedance if used for high-speed signals. Place JTAG pins (TCK, TDI, TDO, TMS) with pull-up resistors as recommended in the datasheet. Decouple each VCC pin with a 0.1uF ceramic capacitor and a 10uF bulk capacitor. Keep the ground plane continuous under the device to minimize noise.
A common pitfall is assuming all 84 pins are user I/O; only 72 are user I/O, with the remaining pins dedicated to power, ground, and JTAG. Do not connect loads to NC pins. Ensure the JTAG pins are not left floating; tie them to appropriate logic levels if not used. Also, verify the speed grade: the -1 variant is faster than the standard, but using a -2 variant in a design that requires 198 MHz will cause timing failures. Always check the temperature range suffix (M for military, I for industrial) to ensure it meets your environmental requirements.
