A42MX16-PLG84A - 24K Gate FPGA, 72 I/O | Microchip Technology
MPN： A42MX16-PLG84A ✓ 啟用中A42MX16-PLG84A 概覽
An FPGA (Field-Programmable Gate Array) is an integrated circuit that can be configured by the customer or designer after manufacturing—hence 'field-programmable'. FPGAs consist of an array of programmable logic blocks and a hierarchy of reconfigurable interconnects that allow the blocks to be wired together in different configurations. This flexibility enables rapid prototyping and design iteration without the cost and lead time of custom ASICs. The MX family is positioned as a reliable, single-chip ASIC alternative, ideal for integrating legacy PLDs into a low-cost, high-volume platform.
Key features of the A42MX16-PLG84A include 24,000 typical gates, 608 logic modules, 72 user I/Os, and a maximum operating frequency of 153 MHz (as noted in Jotrin's listing). The device supports 5.0V I/O and is lead-free, complying with RoHS requirements. The 84-pin PLCC package offers a compact footprint with J-leads, suitable for surface-mount assembly. The industrial temperature range ensures reliable operation in harsh environments.
Technically, the MX family uses a 0.45um process technology, balancing performance and power consumption. The device includes dedicated clock networks and JTAG boundary-scan support for testing and configuration. The FPGA can be programmed using standard design tools, and its non-volatile configuration memory retains the design upon power-up, simplifying system integration.
Typical applications include industrial control, automotive electronics, communications infrastructure, and test and measurement equipment. The 5.0V architecture and 72 I/Os make it suitable for interfacing with legacy logic families and sensors. The device's reliability and long-term availability make it a preferred choice for designs requiring stable supply.
When designing with this FPGA, consider the 5.0V supply requirement and ensure proper decoupling on all power pins. The PLCC package requires a socket or reflow soldering; verify the thermal profile for J-lead packages. Also, plan for JTAG programming during production.

設計說明
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.
