is62/65 wv51216eall is62/65 wv51216ebll integrated silicon solution, inc. - www.issi.com 3 rev. b 10/21 /2014 function description sram is one of random access memories. each byte or word has an address and can be accessed randomly. sram has three different modes supported. each function is described below with truth table. standby mode device enters standby mode when deselected ( high or c s 2 low or both and are high). the input and output pins (i/o0 - 15) are p laced in a high impedance state. the current consumption in this mode will be either isb1 or isb2 depending on the input level. cmos input in this mode will maximize saving power. write mode write operati on issues with chip selected ( low a nd cs2 high) and write enable ( ) input low. the input and output pins(i/o0 - 15) are in data input mode. output buffers are c losed during this time even if is low. and enables a b yte write feature. by e n abling low, data from i/ o pins (i/o0 through i/o7) are written into the location specified on the address pins. and with being low, data from i/o pins (i/o8 through i/o15) are written into the location . read mode read operation issues with chip s elected ( low and c s 2 high) and write enable ( ) input high. when is low, output buffer turns on to make data output. any input to i/o pins during read mode is not permitted. and enables a byte r ead feature. by enabling low, data from memo ry appears on i/o0 - 7. and with being low, data from memory appears on i/o8 - 15. in the read mode, output buffers can be turned off by pulling high . in this mode, internal device operates as read but i/os are in a high impedance state. since device is in read mode, active current is used. truth table mode cs2 i/o0 - i/o7 i/o8 - i/o15 vdd current not selected h x x x x x high - z high - z isb1,isb2 x l x x x x high - z high - z x x x x h h high - z high - z output disabled l h h h l x high - z high - z icc l h h h x l high - z high - z read l h h l l h dout high - z icc l h h l h l high - z dout l h h l l l dout dout write l h l x l h din high - z icc l h l x h l high - z din l h l x l l din din
