This application note presents the clock system configuration tool for the STM32F2xx microcontroller family. The purpose of this tool is to help the user configure the microcontroller clocks, taking into consideration product parameters such as power supply and Flash access mode. The configuration tool supports various functionalities including system clock configuration, HCLK source and output frequency configuration, Flash latency configuration, setting of various frequencies such as PCLK1, PCLK2, TIMCLK (timer clocks), USBCLK, and I2SCLK, and generation of a ready-to-use system_stm32F2xx.c file. It is important to read the STM32F2xx microcontroller reference manual before using the clock tool. This tool supports only revision B and revision Y of the STM32F2xx.
This document presents a clock configuration tool designed for the STM32F2xx microcontroller family. The tool helps users configure system clocks, Flash latency, and peripheral frequencies while considering power supply and Flash access modes. It generates a ready-to-use system_stm32F2xx.c file based on the selected settings.
The note covers software and hardware requirements for using the tool, which runs on Windows XP, Vista, or 7 with Microsoft Office. It provides tutorials for both Wizard and Expert modes, explains the clock scheme for Silicon revisions B and Y, and lists known limitations.
| Supported Silicon Revisions | Revision B and Revision Y |
|---|---|
| Minimum RAM Requirement | 256 Mbytes |
| Operating System Support | Windows XP, Vista, or Windows 7 |
| HSE Oscillator Frequency Range | 4 MHz to 26 MHz |
| HSI Oscillator Frequency | 16 MHz |
| USB OTG FS Clock Frequency | 48 MHz |
The tool requires a recent version of Windows (XP, Vista, or 7) with at least 256 Mbytes of RAM and Microsoft Office installed.
The tool supports only revision B and revision Y of the STM32F2xx.
It generates a ready-to-use system_stm32F2xx.c file containing all system clock settings.
