STMicroelectronics AS-DIP-SO

Overview

AS-DIP-SO is a connection kit from STMicroelectronics designed to interface the ST7MDT10-EMU3 in-circuit emulator with target application boards hosting ST7 microcontrollers in SDIP32 or SO28 packages. It comprises two hardware adapters - DB510 (SDIP32 adapter) and DB359 (SDIP32-to-SO28 device adapter) - enabling physical and signal continuity between emulator and target MCU footprint during debug sessions.

For engineers reviewing the AS-DIP-SO datasheet, AS-DIP-SO pinout, AS-DIP-SO application, or AS-DIP-SO equivalent, this kit supports real-time debugging of ST7-based embedded systems by replicating MCU pinout and timing behavior while allowing emulator access to all signals including reset, clock, and debug I/O lines.

Technical Context

The kit implements passive mechanical and electrical adaptation: DB510 mates directly with the W2 connector on the ST7MDT10-EMU3 emulation board and presents an SDIP32 footprint; DB359 bridges that SDIP32 layout to the SO28 land pattern used by ST7 devices such as ST72324J or ST72321J. No active circuitry or signal conditioning is included.

Both adapters maintain 1:1 pin mapping with verified alignment markers (pin 1 indicators), solderable connection pins for permanent mounting on the application board, and mechanical support features to ensure coplanar insertion and prevent bent pins during repeated connect/disconnect cycles.

Key Specifications

Availability

AS-DIP-SO is available at Aetrix Electronics and suitable for ST7 microcontroller development, in-circuit debugging of industrial control firmware, and validation of SO28/SDIP32-based embedded designs requiring stable component supply across prototyping and pre-production phases.

Supply support for AS-DIP-SO 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

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, specializing in microcontrollers, power management, sensors, and automotive ICs.

This kit belongs to ST's EMU3 emulator accessory product line, engineered specifically to extend debug capability from ST7 evaluation hardware to custom application boards without modifying target PCB layout or sacrificing signal integrity.

FAQ

What MCU families and packages does AS-DIP-SO support?

AS-DIP-SO supports ST7 microcontrollers exclusively in SDIP32 and SO28 packages, including variants like ST72324J, ST72321J, and ST72264G. It is not compatible with QFP, TSSOP, or other ST7 package types, nor with non-ST7 devices, due to precise pin pitch, pad layout, and debug protocol dependencies.

Does AS-DIP-SO require firmware or configuration?

No. AS-DIP-SO is a passive hardware adapter set with no active components, firmware, or configuration requirements. It functions solely as a mechanical and electrical bridge between the ST7MDT10-EMU3 emulator and the target board, relying entirely on the emulator's native SWIM debug interface.

Can AS-DIP-SO be used with newer ST emulators like ST-LINK?

No. AS-DIP-SO is mechanically and electrically designed for the ST7MDT10-EMU3 and its W2 connector. ST-LINK programmers use different pinouts, protocols (SWD vs. SWIM), and physical interfaces, making them incompatible without additional conversion hardware not provided in this kit.

How is AS-DIP-SO mounted on the application board?

AS-DIP-SO is mounted by soldering its connection pins directly onto the application board in place of the target ST7 MCU. The DB359 device adapter serves as a jig during soldering to hold pins aligned; after soldering, the DB510 adapter plugs into DB359, and the full assembly connects to the emulator's W2 port.
