Microchip Technology ATDH2223-

Overview

ATDH2223 from Atmel is an 8-lead SOIC adapter designed to interface the ATDH2200 AT17 Series Configurator Programming Kit with 8-pin SOIC package configuration PROMs. It supports in-system programming of AT17LVxx and AT17Fxx FPGA configuration memory devices, enabling direct JTAG-based configuration loading onto AT40K/AT6000 FPGAs during development and production testing. The adapter features gold-plated contacts and a zero-insertion-force (ZIF) socket for reliable, repeatable connection.

For engineers reviewing the ATDH2223 datasheet, ATDH2223 pinout, ATDH2223 application, or ATDH2223 equivalent, this adapter enables rapid prototyping and reprogramming of FPGA configuration memory without soldering or custom fixtures - critical for iterative FPGA design validation, field firmware updates, and low-volume manufacturing verification workflows.

Technical Context

The ATDH2223 functions as a mechanical and electrical bridge between the ATDH2200 programming base unit and 8-lead SOIC-packaged AT17-series serial configuration PROMs. It maps JTAG signals (TCK, TMS, TDI, TDO) and VCC/GND directly from the ATDH2200's edge connector to the corresponding SOIC pin positions per JEDEC MS-012 standard.

No active circuitry or level-shifting is integrated; signal integrity relies on precise trace routing and contact alignment. Compatibility is strictly limited to AT17LV010, AT17LV020, AT17LV040, AT17F040, and AT17F080 devices in 8-lead SOIC packages - not applicable to PLCC, TQFP, or standalone microcontrollers.

Key Specifications

Supply support for ATDH2223 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Atmel Corporation was a U.S.-based semiconductor manufacturer specializing in microcontrollers, nonvolatile memory, and programmable logic devices before its acquisition by Microchip Technology in 2016.

The ATDH2223 belongs to Atmel's FPGA Development Hardware product line, engineered specifically to simplify and accelerate configuration memory programming for AT40K/AT6000 FPGA families during hardware bring-up and firmware iteration.

FAQ

What is the primary function of the ATDH2223 adapter?

The ATDH2223 adapter provides a plug-and-play interface between the ATDH2200 programming base unit and 8-lead SOIC-packaged AT17LVxx and AT17Fxx configuration PROMs. It enables JTAG-based in-system programming without soldering, supporting rapid FPGA configuration updates during development and lab validation. The ATDH2223 ensures correct pin mapping and signal integrity for reliable bitstream loading onto AT40K/AT6000 FPGAs.

Which specific AT17-series devices are compatible with the ATDH2223?

The ATDH2223 supports only AT17LV010, AT17LV020, AT17LV040, AT17F040, and AT17F080 devices in 8-lead SOIC packages. It is not compatible with PLCC, TQFP, or non-AT17-series memory devices. Compatibility is verified per Atmel Application Note AT17-01 and the ATDH2200 user guide - no other SOIC PROMs are supported, even if pin-count matches.

Does the ATDH2223 require external power or configuration software?

No, the ATDH2223 is a passive mechanical adapter with no active components, power input, or firmware. It draws all operating power and control signals directly from the ATDH2200 base unit via its edge connector. Configuration is handled entirely by Atmel's IDS software suite - no driver installation or additional utilities are needed for ATDH2223 operation.

Can the ATDH2223 be used with modern Windows or Linux hosts?

The ATDH2223 itself has no OS dependency - it is a physical interface adapter. However, full functionality requires the legacy Atmel IDS software (v3.x), which officially supports Windows 98/2000/NT and Solaris 2.4+. Modern Windows 10/11 or Linux systems require compatibility layers or virtual machines running supported OS versions to use ATDH2223 with IDS and ATDH2200.

Is the ATDH2223 pinout documented in any official Atmel resource?

Yes - the ATDH2223 pinout is fully documented in the "ATDH2200E AT17 Series Configurator Programming Kit User Guide" (Rev. 1421D–06/01), Figure 7, which shows exact SOIC pin-to-ATDH2200 edge-connector mapping for TCK, TMS, TDI, TDO, VCC, and GND. No alternate pin assignments or variants exist for the ATDH2223.
