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 memory devices. It supports in-system programming of AT17LVxx and AT17Fxx serial configuration PROMs, provides mechanical alignment and electrical connectivity for reliable programming, and enables direct socket-based connection without soldering or custom fixtures.

For engineers reviewing the ATDH2223 datasheet, ATDH2223 pinout, ATDH2223 application, or ATDH2223 equivalent, this adapter is essential when integrating AT17-series configuration PROMs into FPGA-based systems using the ATDH2200 programming platform - particularly where space-constrained 8-lead SOIC packages require verified, low-risk programming access.

Technical Context

The ATDH2223 serves as a passive mechanical and electrical interface between the ATDH2200 programming base unit and 8-lead SOIC-packaged AT17LVxx/AT17Fxx configuration PROMs. It maps the ATDH2200's standard programming header signals to the correct SOIC pin positions per JEDEC MS-012 outline.

No active circuitry, voltage translation, or logic is present. Signal integrity relies on direct 1:1 pin mapping, gold-plated contacts, and compliant SOIC footprint spacing (1.27 mm pitch). Compatibility is limited to devices matching the AT17 series' VCC (3.3 V or 5 V), I/O voltage levels, and serial configuration protocol timing.

Manufacturer

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

The ATDH2223 belongs to Atmel's FPGA Development Hardware product line, engineered specifically to extend the ATDH2200 configurator's compatibility across multiple AT17-series PROM package variants used in AT40K/AT6000 FPGA configuration workflows.

FAQ

What is the primary function of the ATDH2223?

The ATDH2223 is a passive 8-lead SOIC adapter that enables the ATDH2200 AT17 Series Configurator Programming Kit to program AT17LVxx and AT17Fxx serial configuration PROMs in SOIC-8 packages. It provides precise mechanical alignment and reliable electrical contact without signal conditioning or voltage level shifting. The ATDH2223 ensures full compatibility with the ATDH2200's programming interface and supports both 3.3 V and 5 V AT17-family devices.

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

The ATDH2223 is explicitly validated for use with AT17LV010, AT17LV020, AT17LV040, AT17F040, AT17F080, and AT17F160 configuration PROMs in 8-lead SOIC packages. Compatibility is based on pinout alignment, voltage tolerance, and serial configuration protocol adherence as documented in Atmel's ATDH2200/ATDH2223 hardware reference materials. The ATDH2223 does not support PLCC, TQFP, or other package variants.

Does the ATDH2223 require external power or drivers?

No, the ATDH2223 is a fully passive adapter with no active components, power input, or driver requirements. It draws all necessary power and control signals directly from the ATDH2200 base unit via its standardized programming header. The ATDH2223 functions solely as a precision-mapped interconnect - no software installation, firmware update, or host system configuration is needed to operate the ATDH2223.

Can the ATDH2223 be used with non-Atmel configuration PROMs?

No - the ATDH2223 is mechanically and electrically optimized exclusively for Atmel's AT17LVxx and AT17Fxx series PROMs in 8-lead SOIC packages. Its pin mapping, contact geometry, and voltage tolerances align only with those devices. Using the ATDH2223 with third-party or generic serial PROMs risks misalignment, open/short circuits, or incorrect programming due to undocumented timing or signaling differences. The ATDH2223 is not a universal SOIC programmer adapter.

How does the ATDH2223 differ from the ATDH2221 and ATDH2222 adapters?

The ATDH2223 is dimensionally and electrically distinct from ATDH2221 (20-pin SOIC) and ATDH2222 (20-pin PLCC): it supports only 8-lead SOIC packages with 1.27 mm pitch and JEDEC MS-012 outline, whereas ATDH2221 targets wider 20-pin SOICs and ATDH2222 interfaces 20-pin PLCC sockets. Pin count, pitch, body width, and socket type are mutually incompatible - each adapter serves a unique package family and cannot substitute for another. The ATDH2223 is not interchangeable with either ATDH2221 or ATDH2222.
