Analog Devices Inc. USB-SMBUS-CABLEZ

Overview

USB-SMBUS-CABLEZ from Analog Devices is a USB-to-I²C interface dongle designed exclusively for programming and communication with the ADM1062 through ADM1069 family of programmable super sequencers. It provides SCL, SDA, and GND signals via a 3-pin crimp housing, connects directly to a standard USB port, and enables PC-based configuration of supported I²C devices on evaluation boards.

For engineers reviewing the USB-SMBUS-CABLEZ datasheet, USB-SMBUS-CABLEZ pinout, USB-SMBUS-CABLEZ application, or USB-SMBUS-CABLEZ equivalent, this cable serves as a dedicated hardware bridge between Windows-based evaluation software (v4.0.0+) and target power management ICs-requiring no external power, supporting hot-plug detection, and mandating board power-on prior to connection to prevent damage.

Technical Context

The USB-SMBUS-CABLEZ implements a full-speed USB 2.0 interface using the Cypress CY7C68013A-56LFXC USB microcontroller, which translates USB commands into I²C transactions. It incorporates level-shifting circuitry (P82B96 bus buffer) and local 3.3 V regulation (ADP3303-3.3) to ensure signal integrity and compatibility with 3.3 V I²C targets.

It supports standard-mode (100 kbps) and fast-mode (400 kbps) I²C protocols, uses an internal 24 MHz crystal for timing stability, and includes EEPROM (24LC64) for device identification and firmware storage. The dongle's PCB schematic is shared with USB-5PSMBUS-CABLEZ but omits CONV and ALERT signal routing.

Key Specifications

FAQ

What is the primary function of the USB-SMBUS-CABLEZ?

The USB-SMBUS-CABLEZ is a dedicated USB-to-I²C interface dongle that enables PC-based programming and real-time monitoring of the ADM1062 through ADM1069 super sequencer family. It does not operate as a general-purpose I²C adapter-it is functionally locked to those specific Analog Devices ICs via firmware and hardware design, and its use outside that scope is unsupported.

Which evaluation software versions support the USB-SMBUS-CABLEZ?

The USB-SMBUS-CABLEZ requires Version 4.0.0 or later of the ADM1062–ADM1069 Evaluation Software. Earlier versions lack the required driver stack and command protocol mapping. This software is distributed by Analog Devices and must be installed before connecting the USB-SMBUS-CABLEZ to avoid unrecognized device errors.

Does the USB-SMBUS-CABLEZ provide power to the target board?

No-the USB-SMBUS-CABLEZ does not supply power to the target evaluation board. It only provides SCL, SDA, and GND signals. The target board (e.g., EVAL-ADM106xEB) must be powered independently before connecting the USB-SMBUS-CABLEZ; failure to do so risks damaging both the dongle and the board.

Can the USB-SMBUS-CABLEZ be used with ADM117x or ADM119x devices?

No-USB-SMBUS-CABLEZ is incompatible with ADM1175/ADM1176/ADM1177/ADM1178 or ADM1191x devices. Those require the 5-pin USB-5PSMBUS-CABLEZ, which adds CONV and ALERT signals. The USB-SMBUS-CABLEZ lacks both the physical pins and firmware support for those families.

Is the USB-SMBUS-CABLEZ RoHS compliant?

Yes-the "Z" suffix in USB-SMBUS-CABLEZ explicitly denotes RoHS compliance per Analog Devices' ordering guide. All components listed in the bill of materials-including the CY7C68013A-56LFXC, ADP3303-3.3, and P82B96-are sourced to meet EU Directive 2011/65/EU requirements.
