A42MX16-3PQG208 Tóm tắt

The Microchip A42MX16-3PQG208 is a field-programmable gate array (FPGA) from the 42MX family, offering 24,000 system gates and 608 logic modules in a 208-pin PQFP package. It operates at a maximum internal frequency of 142 MHz and a maximum I/O frequency of 237 MHz, with a 0.45 µm CMOS process and support for 3.3V and 5V I/O. This device provides 140 user I/O pins and is designed as a reliable, single-chip ASIC alternative for integrating legacy PLDs.

An FPGA (Field-Programmable Gate Array) is an integrated circuit that can be configured by the customer after manufacturing to implement custom digital logic. FPGAs belong to the programmable logic device (PLD) family, which sits between ASICs and discrete logic in the hierarchy of digital integrated circuits. The 42MX family is a high-volume, low-cost platform that enables designers to consolidate multiple PLDs into a single device, reducing board space and system cost.

Key features of the A42MX16-3PQG208 include 24,000 system gates, 608 logic modules, and 140 user I/O pins. It supports both 3.3V and 5V I/O levels, making it versatile for mixed-voltage systems. The device is fully tested over automotive and military temperature ranges, ensuring reliability in harsh environments. Additionally, the 42MX family offers selectable PCI output drives on larger devices, enabling compliance with PCI specification version 2.1.

Technically, the A42MX16 is built on a 0.45 µm CMOS process, providing a balance of speed and power efficiency. It features a maximum internal clock frequency of 142 MHz and a maximum I/O frequency of 237 MHz, suitable for moderate-speed applications. The device includes JTAG boundary-scan testing support (IEEE 1149.1) for efficient board-level testing. The 208-pin PQFP package has a 0.5 mm terminal pitch and is available in both plastic and ceramic versions, with the CQ208 and PQ208 packages being pin-compatible for easy prototyping and conversion.

Typical applications for the A42MX16-3PQG208 include industrial control systems, automotive electronics, telecommunications infrastructure, and medical devices. Its ability to integrate multiple legacy PLDs into a single chip makes it ideal for system consolidation and cost reduction. The device's wide temperature range and robust architecture also suit aerospace and defense applications.

When designing with this FPGA, consider the power supply requirements: it supports both 3.3V and 5V I/O, but the core voltage is 5V. Ensure proper decoupling and power sequencing to avoid latch-up. The JTAG interface can be used for in-system programming and testing, simplifying the development process.

The A42MX16-3PQG208 and A42MX16-FPQG208 are both from the A42MX16 family, but the 'F' suffix typically indicates a different speed grade or feature set. The A42MX16-FPQG208MX39 variant has a maximum clock frequency of 56 MHz, while the A42MX16-3PQG208 has 142 MHz. They are pin-compatible but differ in performance.

What is the package type of A42MX16-3PQG208?

The A42MX16-3PQG208 is housed in a 208-pin PQFP (Plastic Quad Flat Package) with a 0.5 mm terminal pitch. The package is designated as S-PQFP-G208. It is a surface-mount package suitable for high-density PCB designs.

Is A42MX16-3PQG208 RoHS compliant?

Yes, the A42MX16-3PQG208 is RoHS compliant, as indicated by the 'G' in the part number, which typically denotes RoHS compliance in Microchip's naming convention. The datasheet and distributor listings confirm RoHS compliance.

Dữ liệu tham khảo kỹ thuật cho A42MX16-3PQG208 — so sánh, hướng dẫn thiết kế và thông tin tuân thủ.

Hướng dẫn chọn lựa

Choose the A42MX16-3PQG208 when you need a moderate-density FPGA (24K gates) with 140 I/O in a 208-pin PQFP package, and you require the highest speed grade (-3) for performance. If you need industrial temperature range, select the A42MX16-3PQG208I. For lower speed requirements, the -1 or -2 variants offer cost savings. If you need more logic resources, consider the A42MX24-3PQG208 (36K gates) or A42MX36-3PQG208 (54K gates), which are pin-compatible. All alternatives share the same package, enabling PCB reuse.

Ghi chú thiết kế

The A42MX16-3PQG208 supports 5V core and 3.3V/5V I/O. Ensure proper decoupling capacitors (0.1µF and 10µF) are placed close to each VCC and GND pin to minimize power supply noise. For low-power systems, the datasheet mentions that all inputs and outputs can be turned off to reduce current consumption to below 500µA. Use this feature in standby modes to save power.

The 208-pin PQFP package has a 0.5mm terminal pitch, requiring careful PCB layout. Use fine-pitch soldering techniques and ensure adequate solder mask clearance. For thermal management, provide a solid ground plane and consider adding vias under the package to improve heat dissipation. Follow the manufacturer's recommended land pattern for the PQFP-208.

Do not exceed the maximum input voltage ratings. The device supports 5V I/O, but ensure that signals from 3.3V logic are level-shifted if necessary. Also, be aware that the A42MX16-3PQG208 is a 5V device; using it in a 3.3V-only system may require level translation. Verify the JTAG interface connections for proper programming and testing.
