现在大家看到的这些,都是季总以前在群里说过的,现在摘抄下来,供新手们学习。      {1}容量差异:24通常以K计量比如24C16就是16kbit,2kbyte.25通常以M计量比如25F32就是32mbit,4mbyte,不过PM25LV512则是512Kbit,64Kbyte  .目前能买到的最大容量的25芯片是256Mbit,32M byte,比如MX25L25635。{2}通讯总线不同:24是I2C总线通讯方式,信号有两根,第5脚是SDA,第6脚是SCL ,25是SPI总线通讯方式,信号有4跟,1脚是CS,2脚是DO,5脚是 D1,6脚是CLK。{3}用途不同:24通常用来保存用户配置数据,比如开关机状态,亮度对比度颜色设置,电视频道信息。25通常保存MCU的固件。
