STMicroelectronics ST7232X-EVAL

Overview

ST7232X-EVAL from STMicroelectronics is an evaluation board designed for the ST7232x and ST7252x 8-bit Flash microcontrollers, featuring a removable 128×64 graphic LCD, PWM-controlled motor speed/beep, RS232/I²C/SPI/CAN interfaces, and on-board 7-segment display with 8 LEDs for I/O status monitoring.

For engineers reviewing the ST7232X-EVAL datasheet, ST7232X-EVAL pinout, ST7232X-EVAL application, or ST7232X-EVAL equivalent, this board supports rapid prototyping of embedded control systems requiring mixed-signal I/O, real-time motor feedback, CAN bus integration, and graphical human-machine interface development.

Technical Context

The ST7232X-EVAL implements the ST-STEP64 architecture, centered on a TQFP64-mounted ST72F521R9T core module enabling standalone operation, while supporting host-PC debugging via ST7MDT20-DVP3 emulator through a 10-pin ICC connector and included flat cable adapter.

It integrates hardware resources aligned with ST7232x/ST7252x peripheral sets: dual PWM channels for motor/beep control, dedicated ADC input via internal potentiometer, four tactile interrupt switches, IR sensor input, and expandable wrapping area for custom circuit integration.

FAQ

Does ST7232X-EVAL include the ST7232x microcontroller?

No. The board ships with an ST72F521R9T core module for standalone operation but does not include ST7232x or ST7252x MCUs. Users must mount their target device onto the provided TQFP64/TQFP80/TQFP32 daughter board footprints for evaluation.

Is the ST7MDT20-DVP3 emulator included with ST7232X-EVAL?

No. The ST7MDT20-DVP3 emulator is sold separately. However, the board includes the required flat cable and adapter to connect it to the emulator when purchased independently.

What software tools are supported for ST7232X-EVAL development?

ST7 Visual Develop (STVD7), a free IDE from STMicroelectronics, is fully supported - including simulator, Cosmic/Metrowerks C compiler integration, in-circuit programming, and real-time debugging via ST7MDT20-DVP3 emulator or direct ICC connection.

Can ST7232X-EVAL be used for CAN protocol validation?

Yes. The board provides a functional CAN transceiver interface with termination and connector, enabling physical-layer testing and firmware validation of CAN message transmission/reception using ST7232x/ST7252x CAN modules in real-world network environments.
