This driver provides functions to configure and program the Flash memory of all STM32F10x devices, |
|
|
including the latest STM32F10x_XL density devices. |
|
|
|
|
|
STM32F10x_XL devices feature up to 1 Mbyte with dual bank architecture for read-while-write (RWW) capability: |
|
|
- bank1: fixed size of 512 Kbytes (256 pages of 2Kbytes each) |
|
|
- bank2: up to 512 Kbytes (up to 256 pages of 2Kbytes each) |
|
|
While other STM32F10x devices features only one bank with memory up to 512 Kbytes. |
|
|
|
|
|
In version V3.3.0, some functions were updated and new ones were added to support |
|
|
STM32F10x_XL devices. Thus some functions manages all devices, while other are |
|
|
dedicated for XL devices only. |
|
|
|
|
|
The table below presents the list of available functions depending on the used STM32F10x devices. |
