1 Introduction

MMstr71xF is universal minimodule for the STR71xF microcontrollers from STMicroelectronics.

This microcontroller is available in the TQFP64 case which is difficult to apply to prototype and

amateur circuits due to the compactness of pins. We have undertaken an attempt at placing it on

a board of 36x36mm with a layout of leads which matches the commonly available prototype

circuit boards. In addition, we have included 3.3V voltage regulator, a serial DataFlash memory

with a capacity of up to 4MB, a circuit monitoring the supply voltage and clock generators for

microcontroller and USB interface. All ports and signals of the microcontroller are lead out by

means of two-row pin connectors with 0.1’ pitch. This minimodule is not only an adapter but a

complete main board for STR71xF. It needs only a connection to the supply voltage and to the

JTAG connector and we can start loading 256kBytes of Flash memory of the microcontroller.

Through integration of the peripherals with the microcontrollers on one board, the application of

this module can lead to a shorter design period and facilitate the construction of systems based

on ARM microcontrollers, by eliminating the need to design the printed board. The module is

supplied with example software.

The MMstr71xF minimodule can be also used in didactic laboratories of informatics colleges and

universities, and can be also used to build circuits realizing thesis projects.

Minimodule can be ordered in different configurations with use of selector:

MMstr71xF – f – u – d

Flash size:

0 – 64kB

1 – 128kB

2 – 256kB

48MHz generator for USB:

0 – not mounted

1 – mounted

DataFlash size:

0 –DataFlash not mounted

1 – 16Mb

2 – 32Mb

For example: MMstr711F-2-0-0 – minimodule with STR711FR2 (256kB Flash), without 48MHz

generator, without DataFlash memory.
