ATNGW100MKII 概述
An embedded MCU evaluation board is a ready-to-use printed circuit assembly that hosts a target microcontroller plus the supporting power, clock, memory, debug, and communication circuitry needed to begin software development immediately. In the product hierarchy it sits under development tools -> evaluation boards and kits -> embedded MCU and DSP evaluation boards, bridging the gap between a bare microcontroller datasheet and a production-locked custom PCB.
Key features of the ATNGW100MKII center on the AVR32 architecture, a 32-bit RISC core family originally developed by Atmel and inherited by Microchip Technology. The platform supports the AT32AP7000, AT32AP7001, and AT32AP7002 application processors, integrates Ethernet networking hardware, and provides a JTAG interface for on-chip debugging and flash programming, which makes it a natural fit for Linux-class gateway and industrial networking designs.
Technically, the AP7000-series devices combine the AVR32 RISC core with on-chip peripherals suited to communication equipment, including Ethernet MAC, USB, and serial interfaces as implemented on the board. The NGW100 mkII iteration refined the original Network Gateway board layout, and the published Atmel document set includes a product overview datasheet plus the EOL notification that defines last-time-buy conditions for the platform.
Typical applications include network gateway prototyping, embedded Linux porting and driver development, industrial automation nodes, and academic teaching of 32-bit RISC embedded systems. The onboard Ethernet and JTAG make the board usable out of the box for both application code and low-level bootloader work.
A key design consideration is lifecycle planning: because the platform is formally EOL/obsolete, new designs should treat the ATNGW100MKII as a maintenance and prototyping tool rather than a long-term production reference, and should budget for last-time-buy stock.

典型应用
ATNGW100MKII 适用于 6 应用s: Embedded Linux Gateway Development, 32-bit RISC Embedded Systems Education, Industrial Automation Legacy Maintenance, Driver and Bootloader Porting, IoT Edge Node Prototyping, Reference Design Reuse for Custom Boards.
Embedded Linux Gateway Development
The ATNGW100MKII was purpose-built as the NGW100 mkII Network Gateway reference platform for AVR32 Linux development. The AT32AP7000-series 32-bit RISC application processor provides the processing headroom and peripheral set required to boot an embedded Linux image, while the onboard Ethernet port enables realistic network-gateway workloads such as packet forwarding, protocol bridging, and lightweight web services. The JTAG interface allows developers to debug U-Boot and kernel bring-up at the register level before the OS is stable. Because the board integrates power, clock, memory, and debug circuitry, a team can begin software work the same day the board arrives. The principal trade-off is lifecycle: with the platform EOL, teams should confine its use to legacy maintenance or educational gateway projects rather than new production designs.
推荐
32-bit RISC Embedded Systems Education
Universities and training labs use the ATNGW100MKII to teach 32-bit embedded systems because it exposes a complete computer: AVR32 RISC CPU, Ethernet, JTAG, and board-level peripherals on a single self-contained assembly. Students can progress from assembly-language exercises through C bare-metal programming to a full embedded Linux port, using JTAG for step-by-step debugging that hides nothing from the learner. The board's documented Atmel datasheet set (product datasheet plus EOL notification) gives instructors stable reference material, and abundant community documentation for the NGW100 family lowers course preparation effort. Since the platform is obsolete, institutions can often acquire boards at reduced cost from the independent market, though per-lab spare availability should be verified before standardizing a multi-year curriculum on this specific hardware.
推荐
Industrial Automation Legacy Maintenance
Control systems that were prototyped or deployed on the NGW100 platform face a maintenance problem now that the ATNGW100MKII is formally EOL. This board serves as a replacement and bench-reference unit: its support for the AT32AP7000, AT32AP7001, and AT32AP7002 targets means firmware images built for the original gateway hardware can be re-validated without fabricating a custom board. The Ethernet interface supports fieldbus-over-IP functions such as Modbus TCP gateways, and JTAG enables recovery of devices with corrupted bootloaders. Teams sustaining such systems should last-time-buy sufficient boards from the independent market (icDirectory has listed over 23,000 units) and archive the Atmel documentation set, while planning a medium-term migration path to a currently supported Microchip platform for any hardware refresh.
推荐
Driver and Bootloader Porting
The ATNGW100MKII is a practical vehicle for low-level software work on AVR32: writing or modifying U-Boot, porting kernel drivers for the AP7000 peripheral set, and validating custom hardware that reuses NGW100 reference circuitry. JTAG access lets engineers single-step through early boot code before any serial console exists, and the board's known-good design isolates software bugs from hardware variables. Because the board supports all three AP700x variants (AT32AP7000/7001/7002), a single bench setup can validate code across the family. Development effort invested here transfers directly to custom AP7000-based designs, since the reference circuitry mirrors typical production implementations. The main caveat is toolchain age: AVR32 GCC and kernel support are frozen upstream, so pin legacy tool versions and containerize the build environment.
推荐
IoT Edge Node Prototyping
For connected edge devices that predate the ARM-only era, the ATNGW100MKII demonstrates the core IoT edge pattern: a 32-bit MCU with Ethernet uplink running a network stack and local control logic. The NGW100 mkII board provides the Ethernet MAC and PHY circuitry plus sufficient processing from the AT32AP7000-class device to run a TCP/IP stack, MQTT-style messaging, or a small HTTP management interface. JTAG aids power-peripheral co-debugging when custom sensor circuitry is attached. The platform is well suited to proof-of-concept work where the goal is validating network protocols and application logic before porting to a current low-power MCU. Given the EOL status, treat it as a prototyping tool only - production IoT designs should move to Microchip's supported SAM or PIC32 ecosystems to secure long-term supply.
推荐
Reference Design Reuse for Custom Boards
Hardware engineers designing custom AT32AP7000-based products can use the ATNGW100MKII as a proven reference design. The board embodies Atmel's recommended implementation of the AP7000 power, clocking, memory, Ethernet, and JTAG circuitry - details that are expensive to derive from the datasheet alone. By lifting schematic blocks from the NGW100 mkII and validating them against the actual board with JTAG measurements, designers de-risk their first spin. The mkII revision also captures layout lessons from the original NGW100, useful for signal integrity on memory and Ethernet lines. Because the platform is EOL, the board itself will eventually disappear from the market, so teams should archive the full schematic and layout files now and consider purchasing at least one golden reference unit for future bring-up comparisons.

设计说明
Treat the ATNGW100MKII as a non-renewable resource. Atmel published a formal Product End-of-Life notification, so no new production exists. Before starting any project on this board, secure your required quantity from the independent market (icDirectory has listed over 23,000 units, and brokers such as Cytech Systems offer quotes) and archive the complete Atmel documentation set - the product datasheet, the EOL notification, schematics, and BSP files - since hosted copies can disappear as datasheet aggregators reorganize.
Freeze your AVR32 toolchain. Upstream GCC, U-Boot, and Linux support for AVR32 is frozen, so newer host toolchains may fail to build legacy BSPs. Containerize the build environment (a known-good GCC for AVR32, matching binutils, and the Atmel BSP) so the project remains reproducible even as developer workstations change. This is the single most common failure mode when teams return to NGW100-class projects years after the platform was discontinued.
When reusing NGW100 mkII reference circuitry in a custom AT32AP7000 board, replicate not only the schematic but also the layout practices for the memory bus and Ethernet magnetics isolation. The mkII revision incorporated corrections learned from the original ATNGW100; compare both board documents before your first spin, and use JTAG on the eval board to validate expected read/write behavior of any memory interface block you copy.
