MPN: A42MX16-1PLG84M ✓ AktifA42MX16-1PLG84M Ringkasan
An FPGA (Field-Programmable Gate Array) is an integrated circuit that can be configured by the customer after manufacturing to implement any digital logic function. FPGAs belong to the programmable logic device (PLD) family, which sits between fixed-function ASICs and general-purpose processors in the digital logic hierarchy. The 42MX family is based on a 0.45um CMOS process and provides a flexible, efficient 5.0V architecture, making it ideal for bridging legacy 5V systems with modern 3.3V logic.
Key features include 24K system gates, 608 CLBs, 72 I/O pins, and support for both 3.3V and 5V supply voltages. The device offers a maximum operating frequency of 119 MHz (internal) and 198 MHz (for the -1 speed grade), with a propagation delay of 1.0 ns. It is available in an 84-pin PLCC package with J-leads, suitable for surface-mount assembly. The A42MX16-1PLG84M is RoHS compliant and supports IEEE 1149.1 (JTAG) boundary-scan testing for board-level verification.
Technically, the 42MX family uses a sea-of-modules architecture with a fine-grained logic cell, enabling efficient implementation of random logic, counters, and state machines. The device includes dedicated clock networks and supports multiple I/O standards, including LVTTL and LVCMOS. The -1 speed grade indicates a faster performance variant, with a maximum clock frequency of 198 MHz. The 0.45um process technology balances density and power consumption, making it suitable for cost-sensitive applications.
Typical applications include industrial control, automotive electronics, communications infrastructure, and legacy PLD consolidation. The 72 I/O pins allow interfacing with a wide range of peripherals, while the 24K gates provide sufficient capacity for medium-complexity logic designs. The dual-voltage support enables seamless integration into mixed 3.3V/5V systems, a common requirement in industrial and automotive environments.
When designing with this device, ensure proper decoupling of the VCC and GND pins with 0.1uF ceramic capacitors placed close to the package. The JTAG interface should be connected for in-system programming and boundary-scan testing. For high-speed designs, pay attention to the clock routing and use the dedicated global clock pins to minimize skew.

Catatan Desain
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.
