This driver provides functions to configure and program the Flash memory of all STM32F10x devices,
|
| 123 |
including the latest STM32F10x_XL density devices.
|
| 124 |
|
| 125 |
STM32F10x_XL devices feature up to 1 Mbyte with dual bank architecture for read-while-write (RWW) capability:
|
| 126 |
- bank1: fixed size of 512 Kbytes (256 pages of 2Kbytes each)
|
| 127 |
- bank2: up to 512 Kbytes (up to 256 pages of 2Kbytes each)
|
| 128 |
While other STM32F10x devices features only one bank with memory up to 512 Kbytes.
|
| 129 |
|
| 130 |
In version V3.3.0, some functions were updated and new ones were added to support
|
| 131 |
STM32F10x_XL devices. Thus some functions manages all devices, while other are
|
| 132 |
dedicated for XL devices only.
|
| 133 |
|
| 134 |
The table below presents the list of available functions depending on the used STM32F10x devices.
