Analog Devices Inc./Maxim Integrated DS9122Q#

Overview

DS9122Q# from Maxim Integrated is a 6-pin TDFN (3mm × 3mm) socket adapter designed for programming 1-Wire® devices including DS2431Q, DS28E15Q, DS28EL15Q, DS28EL22Q, DS28EL25Q, DS28E22Q, and DS28E25Q. It interfaces with the DS9488-GP8 multi-device programmer to enable simultaneous in-system programming of up to eight ICs via 1-Wire or I²C buses. Each socket supports dedicated status LEDs for real-time pass/fail verification during production programming.

For engineers reviewing the DS9122Q# datasheet, DS9122Q# pinout, DS9122Q# application, or DS9122Q# equivalent, this adapter enables rapid, secure, and repeatable programming of Maxim's secure memory and authentication ICs in manufacturing test environments - especially where compact footprint, ESD-safe handling, and dual-protocol (1-Wire/I²C) compatibility are required.

Technical Context

The DS9122Q# is a passive mechanical and electrical interface module - not an active IC - that maps the 6-pin TDFN package of target devices (e.g., DS2431Q) to the DS9488-GP8's 6-pin socket receptacle (SRx) and associated 1-Wire/I²C signal routing. It routes VCC, GND, IO (1-Wire data), SDA, SCL, and optional control lines (e.g., SLPZ) without level-shifting or signal conditioning.

Each DS9122Q# socket connects directly to one of the DS9488-GP8's 16 configurable socket sites (AB01–AB16), supporting either 1-Wire-only or I²C-only operation per socket. The adapter relies on the host programmer's MAX14661 multiplexers and DS2484 1-Wire-to-I²C masters for protocol translation and timing compliance.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in analog, mixed-signal, and digital ICs for industrial, automotive, communications, and computing applications.

The DS9122Q# belongs to Maxim's evaluation system accessory product line, engineered specifically to extend the DS9488-GP8 multi-device programmer's compatibility to surface-mount 1-Wire and I²C devices in compact TDFN packages - enabling scalable, automated programming in manufacturing test floors.

FAQ

What is the DS9122Q# used for?

The DS9122Q# is a socket adapter that enables the DS9488-GP8 programmer to interface with 6-pin TDFN-packaged 1-Wire and I²C devices such as DS2431Q and DS28E15Q. It provides mechanical alignment and electrical connectivity between the target IC and the programmer's socket receptacle, supporting production-grade programming with per-socket LED status feedback. DS9122Q# does not contain active circuitry - its function is purely interpositional.

Which devices are confirmed compatible with the DS9122Q#?

The DS9122Q# is explicitly listed by Maxim as supporting DS2431Q, DS28E15Q, DS28EL15Q, DS28EL22Q, DS28EL25Q, DS28E22Q, and DS28E25Q. These are all 6-pin TDFN variants of Maxim's secure memory and cryptographic authentication ICs. Compatibility is defined by pin count, pitch, and signal mapping - not functional equivalence across families.

Does the DS9122Q# require drivers or firmware?

No - the DS9122Q# is a passive hardware adapter with no embedded logic, microcontroller, or firmware. It requires no drivers. Operation depends entirely on the DS9488-GP8 host board and its installed software plugins (e.g., "DS2431 Programmer Plugin") which must be loaded separately into the Windows-based 1-Wire + I²C Multi-Device Programmer application.

How does the DS9122Q# differ from the DS9122P#?

The DS9122Q# supports 6-pin TDFN (3mm × 3mm) devices, while the DS9122P# supports 6-pin TSOC packages. They are mechanically and electrically incompatible - different footprints, land patterns, and socket receptacle requirements. Neither is interchangeable with the other on the DS9488-GP8 without physical replacement. Both share identical functional roles but serve distinct package types.

Is the DS9122Q# RoHS compliant?

Yes - the DS9122Q# is RoHS compliant, as indicated by the "#" suffix in its part number per Maxim's official Ordering Information table. This designation confirms compliance with EU Directive 2011/65/EU and related restrictions on hazardous substances.
