    命名规范

    | Device | description |
    | ------------- |
    | STM32 |基于ARM?的32位微控制器产品类型。 |
    | F |通用类型产品子系列 |
    |Device subfamily|101 = 基本型 102 = USB基本型 103 = 增强型 105/107 = 互联型|
    |Pin count| T=36 C=48 R=64 V=100 Z=144|
    |Flash Size|6=32 8=64 B=128 C=256 D=384 E=512 |
    |Package|H = BGA T = LQFP U = VFQFPN Y = WLCSP64|

    STM32 产品类型和启动文件的选择

    - startup_stm32f10x_ld_vl.s: for STM32 Low density Value line devices
    - startup_stm32f10x_ld.s: for STM32 Low density devices
    - startup_stm32f10x_md_vl.s: for STM32 Medium density Value line devices
    - startup_stm32f10x_md.s: for STM32 Medium density devices
    - startup_stm32f10x_hd.s: for STM32 High density devices
    - startup_stm32f10x_xl.s: for STM32 XL density devices
    - startup_stm32f10x_cl.s: for STM32 Connectivity line devices
    cl:互联型产品,stm32f105/107系列
    vl:超值型产品,stm32f100系列
    xl:超高密度产品,stm32f101/103系列
    ld:低密度产品,FLASH小于64K
    md:中等密度产品,FLASH=64 or 128
    hd:高密度产品,FLASH大于128
    

    STM32 Flash 页面大小划分

    STM32有4种Flash module organization,分别是:

    • low-density devices(32KB,1KB/page)
    • medium-density devices(128KB,1KB/page)
    • high-density devices(512KB,2KB/page)
    • connectivity line devices(256KB,2KB/page)
    • XL-density(devices(1M,2KB/page)
