JTAG Port Operation
Overview
The JTAG Port on this RAM operates in a manner that is compliant with IEEE Standard 1149.1-1990, a serial boundary scan
interface standard (commonly referred to as JTAG). The JTAG Port input interface levels scale with VDD. The JTAG output
drivers are powered by VDDQ.
Disabling the JTAG Port
It is possible to use this device without utilizing the JTAG port. The port is reset at power-up and will remain inactive unless
clocked. TCK, TDI, and TMS are designed with internal pull-up circuits.To assure normal operation of the RAM with the JTAG
Port unused, TCK, TDI, and TMS may be left floating or tied to either VDD or VSS. TDO should be left unconnected.
