mbed_official | 52:a51c77007319 | 137 | This driver provides functions to configure and program the Flash memory of all STM32F10x devices, |
mbed_official | 52:a51c77007319 | 138 | including the latest STM32F10x_XL density devices. |
mbed_official | 52:a51c77007319 | 139 | |
mbed_official | 52:a51c77007319 | 140 | STM32F10x_XL devices feature up to 1 Mbyte with dual bank architecture for read-while-write (RWW) capability: |
mbed_official | 52:a51c77007319 | 141 | - bank1: fixed size of 512 Kbytes (256 pages of 2Kbytes each) |
mbed_official | 52:a51c77007319 | 142 | - bank2: up to 512 Kbytes (up to 256 pages of 2Kbytes each) |
mbed_official | 52:a51c77007319 | 143 | While other STM32F10x devices features only one bank with memory up to 512 Kbytes. |
mbed_official | 52:a51c77007319 | 144 | |
mbed_official | 52:a51c77007319 | 145 | In version V3.3.0, some functions were updated and new ones were added to support |
mbed_official | 52:a51c77007319 | 146 | STM32F10x_XL devices. Thus some functions manages all devices, while other are |
mbed_official | 52:a51c77007319 | 147 | dedicated for XL devices only. |
