ST AN1809 Application Note
ST AN1810 Application Note
The aim of this application note is to present a practical example of communication using the BSPI peripheral of the STR71x between a STR71x microcontroller and a M25P10-A SPI Serial Flash memory. It shows an easy way of communicating between the STR71x BSPI interface and the M25P10-A serial flash memory from STMicroelectronics, performing write and read operations.
ST AN1946 Application Note
This paper describes the sensorless control and back electromotive force (BEMF) sampling methods for brushless DC motors, as well as the capability of ST7MC in implementing these topologies. The advantages and drawbacks of these topologies are also discussed.
ST AN1947 Application Note
This application note describes a 3-phase synchronous permanent magnet motor control software library developed for the ST7MC drive with sinusoidal waveform. The ST7MC microcontroller contains a peripheral dedicated to 3-phase brushless motor control, making it suitable for AC induction motors and permanent magnet DC/AC motors (PMDC/PMAC, also called BLDC). The library described here is made of several C modules that contain a set of convenient functions for the generation of the sinusoidal waveform, the synchronization mechanism and closed loop control of PMAC induction motors and is compatible with both COSMIC (www.cosmic-software.com) and METROWERKS (www.metrowerks.com) compilers.
ST AN1953 Application Note
AN1953 Application note introduces how to use the ST7MC microcontroller to implement Power Factor Correction (PFC) inside a motor control application.
ST AN1787 Application Note
This application note describes how to migrate designs from the uPSD3200 series to the uPSD3400 series, including pin definitions, SFRs, and interrupt vectors.
ST AN1712 Application Note
This application note presents a software technique for generating a high resolution sine wave using ST7 PWMART. The frequency and average amplitude of the sine wave can be adjusted, and the implementation uses the ST72321J9 microcontroller. PWMART is used to generate a PWM signal, which is then filtered by a low pass filter (a simple RC circuit) to generate the sine wave.
ST AN1903 Application Note
The ST52x440 is a member of ST52 microcontroller family and can be used to implement Sigma-Delta (Σ∆) converters.
ST AN1904 Application Note
This document describes a 3-phase induction motor control software library developed for the ST7MC. This 8-bit microcontroller contains a peripheral dedicated to 3- phase brushless motor control, making it suitable for AC induction motors and permanent magnet DC/AC motors (PMDC/PMAC also called BLDC). The library described here is made of several C modules that contain a set of convenient functions for the scalar control of AC induction motors and is compatible with COSMIC and METROWERKS compilers. The software allows users to quickly evaluate both the MCU and the available tools, and to have a motor running in a very short time when used together with the ST7MC starter kit (ST7MC-KIT/BLDC) and the demonstration AC motor (ST7MC-MOT/IND). It also eliminates the need for time consuming development of sine wave generation and speed regulation algorithms by providing ready-to-use functions that let the user concentrate on his application layer. The prerequisite for using this library is the basic knowledge of C programming, AC motor drives and power inverter hardware.

ST7MC Three-Phase BLDC Motor Control Software Library
ST AN1827 Application Note
This document describes how to implement a 10-bit Sigma-Delta A/D converter using a simple external circuit and a Sigma-Delta conversion program. The ST7FLITE05(09) has an on-chip ADC with 8-bit resolution and an input range of 0-VCC. The external Sigma-Delta ADC described in this application is designed for relatively slow alternating signals (0,2 - 5Hz) in the range 0 - 10mV(p-p). The focus of the project is to provide good relative accuracy, repeatable parameters and simplicity, resulting therefore a low cost of the device (in its simplest form, apart from the microcontroller, only three RC elements are necessary).

ST AN1755 Application Note
This application note presents a realistic example of a thermometer using an ST7 and an NE555.
ST AN1774 Application Note
This document provides an introduction to the STR71x product family. It describes the software environment required to develop an STR71x application from scratch. It summarizes the different steps needed to configure the development toolset and to use the template software library to build and debug a sample STR71x application on the target hardware. Two software examples are supplied with this application note. Both are intended for users new to STR71x microcontrollers. The first one is a standard application demonstrating an input/output pin toggling function. The required steps to create this example project, to build and debug the image are described in the first chapter. The second one illustrates an advanced example showing the use of interrupts. Both examples are loaded and executed from the STR71x embedded RAM, and then the target hardware has to be configured accordingly (BOOTEN/1/0=”110”). The application source files are provided within the package ’AN1774.zip’. This document assumes that the reader is familiar with ARM cores. For more details on the ARM core architecture, refer to the ARM Developer Suite Guide and the ARM Technical Reference Manual. These documents are available from ARM website.
ST AN1775 Application Note
This application note introduces the hardware development of STR71x product family, including power management, clock management, reset control, boot mode settings and debug management, and provides detailed reference design schematics.
