SIM卡的基本结构
SIM卡是带有微处理器的芯片， 内有5个模块，每个模块对应一个功能：
CPU(8位/16位/32位)
程序存储器ROM
工作存储器RAM
数据存储器EEPROM
串行通信单元
这5个模块集成在一块集成电路中。
SIM卡在与手机连接时，最少需要5个连接线：
电源(Vcc)
时钟(CLK)
数据I/O口(Data)
复位(RST)
接地端(GND)
其中：
GND 地 基准电压
VCC 电源输入
I/O 串行数据的输入/输出
CLK 时钟信号输入
RST 复位信号输入
VPP 编程电压输入 由卡选用
SIM卡的通信时序
SIM卡的上电复位有2种，一种是冷复位，另外一种是热复位。
所谓冷复位就是VCC会拉低后再拉高，即VCC先断电，然后再给电。所谓热复位就是VCC不断电，RESET管脚会先先拉低后再拉高。
冷复位的时序图如下：
热复位的时序图如下：
SIM卡之ART含义
SIM卡上电后，会与主机进行通信握手信号。在进行握手的过程中，主机可能会尝试电压从CLASS_A--CLASS_C的尝试，从而选择一个合适的电压供电。
当供电电压选定后，SIM卡会发出ATR(复位应答信号)，主机会返回PPS，SIM卡会对PPS做出应答，其中PPS与PPS应答过程是可选的。
ATR包括的信息有：信号约定：即高电平有效(正向约定)还是低电平有效(反向约定)、通信速率、电压类型等信息(详细可以看规范ISO7816-3部分)。
PPS为通信速率协商。可以理解为SIM卡与主机协商双方用多大的速率来进行数据通信。
| 数据元 | 说明 |
| TS | 起始字符（强制性的） |
| T0 | 格式字符 （强制性的） |
| TA1，TB1，TC1，TD1，… | 接口字符（可选） |
| T1，T2，… ，TK |
|
| TCK |
|
1.起始字符TS
TS为强制性的部分，该部分有两种约定，3B:表示正向约定，高电平为1 低电平为0；3F反向约定
2.格式字符T0
该字节用来表示接口字符的个数和历史字节的个数
该字节高四位的1 的位置表示是否有历史字符例如 1111表示TA1，TB1，TC1，TD1都有
3.接口字符TA1，TB1，TC1，TD1，…
TA1：公式为3571200/(Fi/Di),Fi为高四位查表Di为第四位查表
FI和DI编码如下：
2.SIM卡初始流程
1)模块开机上电时先开始检测SIM卡。1.8V供电给SIM卡（不成功切换3.0V供电voltage class）。基本上，模块会有尝试3次recovery的动作。
2)模块把SIM卡的controller 的RESET PIN拉动,当SIM卡收到controller 的RST后会回复一串字符串，称为ATR。
3)ATR里面包含了一些卡的信息。根据ATR里面的卡信息去分类SIM卡类型及之间的交互方式。
4)收到 ATR后，进入PPS negotiation，UICC与 modem将会协商clk rate和baud rate(FI,DI)。

3.SIM卡相关的EVENT
这部分主要介绍了当SIM发生insert和remove操作后，会有哪些EVENT发生，根据这些EVENT，方便我们确认SIM卡处于哪一种状态。根据这些状态，分别做相应的处理。下面是QXDM log的关键点：
1）Card insert event
User Identity Module/High[ mmgsdi.c 8849] Received event: 0x0 in mmgsdi_evt_cb
User Identity Module/High[ mmgsdi.c 9220] MMGSDI_CARD_INSERTED_EVT, slot: 0x1
DS AT Command Parser/High[ dsatme_ex.c 1894] dsatme_mmgsdi_event_handler for event: 0, Session id: 0 Apps ID: 5, slot_id 1
2) Session changed event
DS AT Command Parser/High[ dsatme_ex.c 1894] dsatme_mmgsdi_event_handler for event: 13, Session id: 68 Apps ID: 0, slot_id 1
3) PIN1 event
DS AT Command Parser/High[ dsatme_ex.c 1894] dsatme_mmgsdi_event_handler for event: 14, Session id: 68 Apps ID: 0, slot_id 1
4) PIN2 event
DS AT Command Parser/High[ dsatme_ex.c 1894] dsatme_mmgsdi_event_handler for event: 15, Session id: 68 Apps ID: 0, slot_id 1
5)Personalization event
DS AT Command Parser/High[ dsatme_ex.c 1894] dsatme_mmgsdi_event_handler for event: 19, Session id: 68 Apps ID: 0, slot_id 0
6)Ready event
DS AT Command Parser/High[ dsatme_ex.c 1894] dsatme_mmgsdi_event_handler for event: 12, Session id: 68 Apps ID: 0, slot_id 1
当这个事件状态上报后，SIM卡的初始话工作已经基本完成，后续它还会把短信和电话本读取到cache中。
7)Card error error
当出现开机不识卡和掉卡等情况时，会有这个event发生。
User Identity Module/High[ mmgsdi.c 8849] Received event: 0x1 in mmgsdi_evt_cb
User Identity Module/High[ mmgsdi.c 9303] MMGSDI_CARD_ERROR, condition: 0x3, slot: 0x1
DS AT Command Parser/High[ dsatme_ex.c 1894] dsatme_mmgsdi_event_handler for event: 1, Session id: 0 Apps ID: 5, slot_id 1
8)Refresh event
这个事件一般发生在MBN更新或者网络下发特别短信触发的，这个短信可能触发BIP的动作或者修改某个文件。下面主要介绍下短信触发的流程：

5. SIM STK 过程

MDM9205 SIM issue(voltage 3V).isf： SIM在交互过程中上报只支持3V和5V，因为MDM9205平台只支持1.8V，所以识别卡失败。
