Analog Devices Inc. RAPID-NI-V2105

Overview

RAPID-NI-V2105 from Innovasic is a DLR Network Interface module integrating communications controller, protocol stacks, Flash, RAM, and analog Ethernet drivers for Device Level Ring (DLR) industrial networks. It supports dual 10/100BASE-TX Ethernet ports with Link/Activity LEDs, operates from a single +3.3V supply, consumes ~1.5W, and interfaces via UART or 16-bit parallel host interface.

For engineers reviewing the RAPID-NI-V2105 datasheet, RAPID-NI-V2105 pinout, RAPID-NI-V2105 application, or RAPID-NI-V2105 equivalent, this page delivers verified mechanical dimensions (51.5 × 56.3 × 18.2 mm), 64-pin 0.1" socket interface, 3.3V logic compatibility, dual Ethernet port timing behavior, and bootloader/JTAG/flash programming support - all critical for embedded industrial control integration.

Technical Context

The RAPID-NI-V2105 implements a complete DLR node stack including ring supervision, media access control, and deterministic Ethernet frame handling. It integrates fido®-based real-time processing, on-board TC1270A voltage supervisor for reset management, and isolated Ethernet line-side grounding via X1-C10 chassis ground.

Host communication is supported through two mutually exclusive modes: UART (TX/RX on X1-C3/C4) or 16-bit parallel interface using dedicated read/write FIFOs with handshaking signals (e.g., FIFONOTEMPTY_N, WR_SEL_N, RD_SEL_N). All I/O signals are 3.3V logic level, with inputs (except MAN_RESET_N) 5V tolerant.

FAQ

What is the primary function of the RAPID-NI-V2105?

The RAPID-NI-V2105 is a fully integrated DLR Network Interface module that implements the Device Level Ring protocol stack, dual-port 10/100BASE-TX Ethernet physical layer, and host interface logic. It enables industrial devices to join and maintain a deterministic, self-healing ring topology without requiring custom firmware development - the RAPID-NI-V2105 handles ring supervision, frame forwarding, and fault detection autonomously.

Does the RAPID-NI-V2105 require an external reset signal?

The RAPID-NI-V2105 includes an on-board TC1270A voltage supervisor IC and can initialize without an external reset if power sequencing meets specifications. However, for deterministic startup control, an external active-low pulse ≥10 µs applied to MAN_RESET_N (X1-B8) is supported. The module asserts RESET_OUT_N (X1-B16) during reset, and full operational readiness occurs 1.0 second after valid reset or power stabilization.

Which host interfaces does the RAPID-NI-V2105 support, and are they concurrent?

The RAPID-NI-V2105 supports either UART (X1-C3/TX, X1-C4/RX) or 16-bit parallel interface (using UIC0/UIC1 signals across X1-A/B/C/D rows), but not both simultaneously. The interface mode is selected at design time via hardware configuration and firmware initialization - no runtime switching capability is provided in the RAPID-NI-V2105.

How is the RAPID-NI-V2105 programmed or updated in production?

The RAPID-NI-V2105 supports three independent programming methods: (1) Ethernet bootloader using .load files, (2) JTAG via RapID-PGMR VMCGR wiggler and .elf files, and (3) offline flash programming using .srec files. Bootloader mode requires BOOTLOAD_EN_N (X1-B2) grounded at power-up; JTAG and flash programming do not require this signal assertion.

What mechanical and electrical considerations apply to the RAPID-NI-V2105's connector interface?

The RAPID-NI-V2105 uses a 64-pin, 0.1" pitch socket (4×16 layout) with Samtec SSW-116-21-F-D as the recommended mating connector (height ≤8.51 mm). Chassis ground is provided at X1-C10 for Ethernet isolation. Unused pins are NC or spare; all signal pins are 3.3V logic, with only MAN_RESET_N (X1-B8) non-5V-tolerant - requiring strict 3.3V drive.
