点击看大图


上图为S29GL P系列的TSOP56的脚位图


如果是S29GL128P A23 A24 A25多是空脚,即S29GL128P的地址是


A0-A22,23条地址线A的23次即8M,8M乘以16位(DQ0-DQ15)


就是128Mbit;


如果S29GL128P不使用16位数据模式,即使用8位数据模式(DQ0-DQ7),这时候DQ15 充当最低位地址线A-1,这时候的地址线为A-1 - A22 24条地址线,即16M*8bit=128Mbit, 8位/16位数据模式通过第53脚


BYTE#来选择,


当BYTE为低,器件工作在8位数据模式,A-1 - A22 ,24条数据线,8位数据位(DQ0-DQ7);


当BYTE为高,器件工作在16位数据模式,A0 - A22 ,23条数据线,16位数据位(DQ0-DQ15);


8位数据模式节省了IO空间,IO比较紧张的时候简易使用8位数据模式;


16位数据模式用的IO口比8位多7个IO,IO充裕请选16位模式;


16位数据模式虽然多用7个IO,但是他一次能读16位数据,所以读完


FLASH所用的时间比8位数据位模式快一倍;
