STMicroelectronics Manuals

This application note presents the implementation of a Device Firmware Upgrade (DFU) capability in ST7 USB microcontrollers. It follows the DFU class specification defined by the USB Implementers Forum, for reprogramming an application through USB. The DFU principle is particularly well suited to USB applications that require need to be reprogrammed in the field: The same USB connector can be used both for the standard operating mode, and for the reprogramming process. This operation is made possible by the IAP capability featured by most of the ST7 microcontrollers, which allows a FLASH MCU to be reprogrammed by any communication channel. The DFU process, like any other IAP process, is based on the execution of firmware located in Sector 0 of the ST7 Flash memory which manage the Flash operations (erasing and programming) of Sectors 1 and 2. This application note covers then two main aspects: The firmware located in Sector 0, The Interface between the firmware in Sector 0 and the firmware in Sectors 1 & 2. The proposed implementation is demonstrated with 2 different projects: the USB Low-Speed devices Evaluation Kit and the ST7265 Full-Speed 5-in-1 demoboard. In this document these projects are referred to as “LS project” and “FS project”. A basic DFU protocol is also introduced.

The In-Application Programming (IAP) drivers provided by STMicroelectronics allow for flexible communication methods and protocols for reprogramming ST7 FLASH microcontrollers.

This document presents guidelines for upgrading from the ST92F120 (0.50µm) to the ST92F124/F150/F250 (0.35µm). Microcontrollers for embedded applications are integrating more peripherals and larger memories. Shrinking the microcontroller die size is necessary to provide the right products with the right features at the right cost. The purpose of this document is to highlight the differences between the ST92F120 (0.50µm) and ST92F124/F150/F250 (0.35µm) microcontrollers and provide guidelines for upgrading the application's software and hardware.

This document provides an sufficiently accurate description of the testflash content to allow the user to access to the different parameters and routines included in the testflash

Extending the current & voltage capability on the ST7265 VDDF supply

This application note presents various ways of programming an ST7 MCU that has already been soldered on a PCB. This includes using STFLASH Programmer and ST-LINK Utility to program MCUs on a production line or while the MCU is running.

This document describes the features and characteristics of the ST7 microcontroller, specifically the accurate timebase application using the internal RC oscillator.

AN1527 APPLICATION NOTE DEVELOPING A USB SMARTCARD READER WITH ST7SCR

AN1544 is an application note on how to design applications based on ST10F269. The note contains six main items: the use of external resonator with the on-chip oscillator, startup configuration and necessary precautions, filtering, decoupling and special pins use, recommendations to reduce ADC conversion errors, memory interface, and interfacing with the L4969 CAN interface.

This application note provides information on using ST72264 new series in an application orig- inally designed for the ST72254, 215, 216, 104 series.

This Application Note describes how to emulate this feature with a ST72F521 device and the restrictions this emulation implies.

This application note presents a software solution using the frequency of the European standard mains (220V/50Hz) as a timebase to adjust the internal RC oscillator of the ST7FLITE0 microcontroller.

This is the datasheet of STP12PF06 P-CHANNEL 60V - 0.18 Ω - 12A TO-220/TO-220FP STripFET™ II POWER MOSFET

STP11NM80, STB11NM80, STF11NM80 and STW11NM80 are N-Channel 800V, 0.35 Ohm, 11A TO-220/FP/D2PAK/TO-247 MDmesh™ Power MOSFETs with outstanding low on-resistance, impressively high dv/dt and excellent avalanche characteristics. This product is very suitable for single switch applications, especially for Flyback and Forward converter topologies.
