ST7232X-EVAL

Insem’s ST-STEP64 Evaluation Board for ST7232x and ST7252x

DATA BRIEF

The

Insem ST-STEP64 Evaluation Board

(ST7232X-EVAL)

evaluation board that allows you to try out the
features of the ST7232x and ST7252x, and
develop applications for these microcontrollers. Its
innovative design allows stand-alone operation
(application running on the included ST72F521R
microcontroller), or operation while connected to
your host-PC using the low-cost ST7MDT20­DVP3 emulator.

is an adaptable, full-featured

evaluation board (PWM, LCD, I
CAN, potentiometer, LEDs, I/Os,... etc.), it
includes connectors and accessories to facilitate
switching between operation with a
microcontroller or the ST7MDT20-DVP3 emulator.
The ST-STEP64 also integrates a 10-pin ICC
connector for easy programming of the
microcontroller using an in-circuit programming
tool for ST7.

TQFP64 14x14 Core Module with
ST72F521R9T – included daughter board with

ST72F521R97 that makes it possible to run your
application in stand-alone mode on the
microcontroller.

Also Includes pre-wired daughter board PCBs,
ready for mounting of connectors and supported
MCUs in TQFP80 (14x14), TQFP64 (10x10) and
TQFP32, so that you can make your own Core
Module for an ST7232x or ST7252x.

ST7MDT20-DVP3 emulator (not included)

low-cost ST7-DVP3 series emulator provides a
hardware interface with the host PC for debugging
application software and in-circuit programming of
the ST72F521R97 or other ST7 flash
microcontroller. The evaluation board comes with
the additional flat cable and the adapter required
for connection to an ST7MDT20-DVP3 emulator.

For more information about the ST7MDT20­DVP3, please refer to the

ST7 Visual Develop (STVD7)

integrated development environment for ST7
featuring simulator and full integration of Cosmic
and Metrowerks C toolsets. STVD7 runs on the
host PC, allowing you to debug applications with
an emulator, or to in-circuit program an application
to the target ST7 and in-circuit debug the
application while it runs on the ST7 on your
evaluation board.
