Product details
Overview
STM3240G-JAVA from STMicroelectronics is a Java evaluation kit for the STM32 F4 series, centered on the STM32F407IGH6 MCU and preloaded with a Java demo. It includes the STM3240G-EVAL board, STM32Java SDK (MicroEJ®-based), 3.2" 240×320 TFT LCD with touch, Ethernet with TCP/IP stack, and embedded ST-LINK/V2 debugger.
For engineers reviewing the STM3240G-JAVA datasheet, STM3240G-JAVA pinout, STM3240G-JAVA application, or STM3240G-JAVA equivalent, this kit supports rapid prototyping of Java-based embedded HMI, networked control, and real-time UI applications on ARM Cortex-M4 hardware with hardware floating-point acceleration.
Technical Context
The kit implements MicroEJ® Virtual Machine (VM) on STM32F407IGH6, enabling Java bytecode execution with native C integration via SNI and SP interfaces. It targets Eclipse-based development and includes MicroUI™ for pixel-accurate GUI rendering and MWT for widget composition.
Hardware abstraction covers LCD controller, Ethernet MAC/PHY (via external PHY), USART, GPIO buttons/LEDs, and touch controller - all exposed to Java through standardized JPF APIs. The evaluation version enforces 3-month license duration and 1-hour runtime limit per session.

FAQ
Is STM3240G-JAVA still in production?
No - STM3240G-JAVA is an obsolete evaluation kit discontinued by STMicroelectronics as of 2013. It remains available through authorized legacy distributors and Aetrix Electronics for continuity support, but no firmware updates, technical documentation revisions, or replacement parts are issued.
What Java environment does it use?
It uses MicroEJ® Virtual Machine (v3.x), built on Eclipse IDE, with MicroUI™ for GUI and MWT for widgets. Java code compiles to MicroEJ bytecode, executes on the STM32F407IGH6, and interfaces with hardware via SNI and Shielded Plug (SP) abstractions.
Can I deploy commercial applications with this kit?
No - the included STM32Java SDK is an evaluation version restricted to 3 months' license validity and 1 hour of runtime per session. Commercial deployment requires a licensed MicroEJ® SDK subscription and separate agreement with MicroEJ SA.
Does it support modern IDEs or debuggers?
It integrates with Eclipse IDE (v3.7+), using ST-LINK/V2 for SWD-based debugging. While not compatible with VS Code or modern STM32CubeIDE out-of-the-box, debug symbols and ELF output allow third-party toolchain adaptation with manual configuration.
