Analog Devices Inc. RAPID-NI-V2007

Overview

RAPID-NI-V2007 from Innovasic is a pre-integrated network interface module with REM (Remote Enable/Disable) switch functionality, designed for industrial field devices requiring dual Ethernet port connectivity, embedded protocol stacks, and host processor interfacing via UART or 16-bit parallel bus. It integrates communications controller, Flash, RAM, PHYs, and isolated Ethernet line-side grounding in a 60.5 mm × 56.3 mm × 18.2 mm form factor, powered by a single +3.3 V supply and consuming ~1.8 W.

For engineers reviewing the RAPID-NI-V2007 datasheet, RAPID-NI-V2007 pinout, RAPID-NI-V2007 application, or RAPID-NI-V2007 equivalent, key selection considerations include its dual RJ45 Ethernet ports with Link/Activity LEDs, 64-pin 0.1" socket interface (SSW-116-21-F-D compatible), on-board TC1270A reset supervisor, and support for bootloader (.load), JTAG (.elf), and flash programmer (.srec) firmware updates.

Technical Context

The RAPID-NI-V2007 implements two independent Ethernet interfaces with integrated PHYs and line-side isolation, managed by an embedded fido® real-time OS and Unified Interface software stack. Its host communication supports either UART (TX/RX on X1-C3/C4) or 16-bit parallel FIFO interface (UIC0/UIC1 signals across X1-A/B/C/D rows), with dedicated control lines including FIFONOTEMPTY_N, WR_SEL_N, RD_SEL_N, and INT4.

Reset behavior is governed by the TC1270A voltage supervisor: MAN_RESET_N (X1-B8) accepts a low pulse ≥10 µs to initiate reset, while RESET_OUT_N (X1-B16) provides active-low status indication. Bootloader entry requires BOOTLOAD_EN_N (X1-B2) grounded at power-up, enabling field firmware updates over Ethernet without hardware rework.

FAQ

What is the primary function of the RAPID-NI-V2007 in an industrial system?

The RAPID-NI-V2007 serves as a complete, drop-in network interface subsystem that enables field devices to connect to industrial Ethernet networks with minimal host processor overhead. It handles physical layer signaling, MAC-layer operations, protocol stack execution (including REM switch control), and firmware update management-allowing host microcontrollers to focus on application logic rather than low-level networking tasks. The RAPID-NI-V2007 integrates all required components: PHYs, Flash, RAM, and supervisor IC.

Does the RAPID-NI-V2007 support both UART and parallel host interfaces simultaneously?

No, the RAPID-NI-V2007 supports UART and parallel host interfaces as mutually exclusive configuration options-not concurrently. Signal multiplexing is implemented at the pin level: for example, UIC1_16 functions as UART TX in serial mode but as RD_SEL_N in parallel mode. Hardware design must select one interface type during board layout, and firmware must be configured accordingly. The RAPID-NI-V2007 does not auto-detect or dynamically switch between modes.

How is Ethernet port isolation implemented on the RAPID-NI-V2007?

Ethernet port isolation on the RAPID-NI-V2007 is achieved through line-side isolation referenced to chassis ground (X1-C10), physically separating the Ethernet PHY circuitry from the module's signal ground plane. This design meets industrial EMC requirements and prevents ground loops in distributed control systems. The RJ45 connectors extend 3.0 mm beyond the PCB edge to accommodate enclosure mounting while maintaining isolation integrity. The RAPID-NI-V2007 does not include transformer modules on-board; isolation is implemented externally in the connector assembly.

What are the critical timing requirements for asserting MAN_RESET_N on the RAPID-NI-V2007?

The MAN_RESET_N signal (X1-B8) must be held low for a minimum duration of 10 µs to guarantee reliable reset initiation by the on-board TC1270A supervisor IC. The signal is not 5 V tolerant and must be driven with a clean +3.3 V logic-level source. Reset assertion can occur at any time during operation, but the RAPID-NI-V2007 will not enter functional operation until 1.0 second after the reset pulse ends or after power stabilization if no external reset is applied.

Can the RAPID-NI-V2007 be programmed in-system without removing it from the target hardware?

Yes, the RAPID-NI-V2007 supports in-system programming via three methods: Ethernet-based bootloader (.load files), JTAG interface (.elf files using RapID-PGMR VMCGR), and flash programmer (.srec files). All methods operate while the module is installed in the end equipment. The bootloader method requires BOOTLOAD_EN_N (X1-B2) grounded at power-up; JTAG access uses a dedicated header shown in Figure 9; and flash programming targets the on-board SPI Flash directly. No disassembly or rework is needed for field updates.
