IEEE 1149.1 SERIal BOUNDaRY SCaN (JTaG)
TheIS61LPD/VPD51236AandIS61LPD/VPD102418A
haveaserialboundaryscanTestAccessPort(TAP)inthe
PBGApackageonly.(TheTQFPpackagenotavailable.)
This port operates in accordance with IEEE Standard
1149.1-1900,butdoesnotincludeallfunctionsrequired
forfull1149.1compliance.ThesefunctionsfromtheIEEE
specificationareexcludedbecausetheyplaceaddeddelay
inthecriticalspeedpathoftheSRAM.TheTAPcontrol-
ler operates in a manner that does not conflict with the
performanceofotherdevicesusing1149.1fullycompliant
TAPs.TheTAPoperatesusingJEDECstandard2.5VI/O
logic levels.
DISaBlING THE JTaG FEaTURE
TheSRAMcanoperatewithoutusingtheJTAGfeature.
To disable the TAP controller, TCK must be tied LOW
(Vss)topreventclockingofthedevice.TDIandTMSare
internallypulledupandmaybedisconnected.Theymay
alternatelybeconnectedtoVddthroughapull-upresistor.
TDOshouldbeleftdisconnected.Onpower-up,thedevice
will start in a reset state which will not interfere with the
device operation.
