This application note provides an overview of the STR73x power management features and gives some guidelines for using the low power modes to minimize the power consumption of the microcontroller. Example software is provided with this application note for implementing and showing the various low power modes.

This document describes the features of the SystemMemory boot mode developed for STR73x Flash microcontrollers to provide all the basic functionality to support programming of the embedded Flash. It will describe its general features, and then move on to specific features of the UART boot mode.

This document describes the implementation of a current regulator for BLDC motor control. It provides an overview of various approaches for obtaining current feedback and analyzes the limitations of each approach. The document also presents a simple, linear, and cost-effective method of implementing the inner current loop by sampling the DC link current at the mid-point of PWM 'on time' with ST7FMC. Experimental results are also discussed.

This document describes a firmware implementation for an Ekey-Udisk device based on ST72651. The software is divided into 3 parts: USB management, NAND Flash interface, and Smart Card interface.

This application note describes how to design a printed circuit board (PCB) with optimum performance and compatibility between ST92E196 or ST92T196 (SDIP56 package) and ST92186 (SDIP32 and SDIP42 packages) microcontrollers. It also describes the external filters and components needed for the ST92186 family of microcontrollers (MCU), and provides advice on how to develop applications for ST92186 microcontrollers in SDIP32 or SDIP42 packages using ST92E196 / ST92T196 devices.

This document introduces the STP16CP05 and STP16CPS05 LED drivers and provides two reference designs, for driving 80 and 32 high brightness LED arrays, respectively.

The purpose of this application note is to show users of the ST7LITE2 ADC how to achieve 13-bit resolution with the internal amplifier. It also explains the software methodology, which can be applied to find and cancel the amplifier offset error. A reference application is shown with implementation of hardware and software filtering techniques (using an averaging algorithm) to minimize the ADC error.

The purpose of this application note is to provide STR73x family device users with a number of recommendations on the HW circuitry connected to the main special pins. It covers the pins for power supply (digital and analog), reset, crystal oscillator, the decoupling of the internal voltage regulator, boot modes, test pin, RC oscillator biasing pin and the JTAG debug port. Detailed reference design schematics of the STR730-EVAL board are also contained in this document with descriptions of the main components, interfaces and modes.

AN2164 is an application note published by ST, which introduces how to connect ST10 with external memory. The application note is divided into two parts. The first part introduces the features of the ST10 external bus, including the EBC operating modes, port pins timing and maximum addressable space. The second part describes how to connect external memory, discussing both demultiplexed and multiplexed buses and giving examples of word-wide and byte-wide memory.

This document provides a design guide for the uPSD3200 family of MCUs. It introduces the features and characteristics of the products, and describes how to use the DK3200 development board, PSDsoft Express software, and Keil Software's uVision2 8051 integrated development environment to create a design.

This article introduces the ST7MC microcontroller family, which is the second generation of the 8-bit microcontroller family dedicated to driving 3-phase brushless DC motors. These microcontrollers have advantages such as high efficiency, low noise, and better reliability, and are suitable for both sensor and sensorless methods of permanent magnet brushless DC motor control.

This application note introduces some software techniques for compensating and minimising ST7 ADC errors. The document also provides some general tips on writing ADC software. For a list of related application notes that contain other useful information about ADCs see section 6 on page 39. This document provides some methods of calibrating the ADC. Some ADC errors like Offset and Gain errors can be cancelled using these simple software techniques. Other errors like Differential Linearity Error and Integral Linearity Error are associated with the ADC design and cannot be compensated easily. The example software provided with this application note is explained in brief in section 5 on page 35.
