MOTOROLA FAST SRAM
SERIAL BOUNDARY SCAN TEST ACCESS PORT OPERATION
OVERVIEW
The serial boundary scan test access port (TAP) on this
RAM is designed to operate in a manner consistent with
IEEE 1149.1–1990 (commonly referred to as JTAG), but
does not implement all of the functions required for 1149.1
compliance. Certain functions have been modified or elimi-
nated because their implementation places extra delays in
the RAMs critical speed path. Nevertheless, the RAM sup-
ports the standard TAP controller architecture. The TAP con-
troller is the state machine that controls the TAP operation
and can be expected to function in a manner that does not
conflict with the operation of devices with IEEE 1149.1
compliant TAPs. The TAP operates using conventional
JEDEC Standard 8–1B low voltage (3.3 V) TTL/CMOS logic
level signaling.
DISABLING THE TEST ACCESS PORT
It is possible to use this device without utilizing the TAP. To
disable the TAP controller without interfering with normal
operation of the device, TCK must be tied to VSS to preclude
mid–level inputs. TDI and TMS are designed so an undriven
input will produce a response identical to the application of a
logic one, and may be left unconnected. But they may also
be tied to VDD through a 1 k resistor. TDO should be left
unconnected.
