allowable range of RQ to guarantee impedance matching with a tolerance of 15% is between
150 Ω and 300 Ω. If the status of ZQ pin is open, output impedance is maximum. Maximum
impedance occurs with ZQ connected to V
occurs when the SRAM is in High-Z. Write and Deselect operations will synchronously switch
the SRAM into and out of High-Z, therefore triggering an update. The user may choose to
invoke asynchronous G updates by providing a G setup and hold about the K clock to guarantee
the proper update. At power-up, the output impedance defaults to minimum impedance. It will
take 2048 cycles for the impedance to be completely updated if the programmed impedance is
much higher than minimum impedance.

Boundary Scan Test Access Port Operations
In order to perform the interconnect testing of the modules that include this SRAM, the serial boundary
scan test access port (TAP) is designed to operate in a manner consistent with IEEE Standard 1149.1 -
1990. But does not implement all of the functions required for 1149.1 compliance The HM62Gxx series
contains a TAP controller. Instruction register, Boundary scans register, Bypass register and ID register.

Notes: 1. Bit number1 is the first scan bit to exit the chip.
2. The NC pads listed in this table are indeed no connects, but are represented in the boundary

3. In Boundary scan mode, differential input K and K are referred to each other and must be at
opposite logic levels for reliable operation.
Note: The value adjacent to each state transition in this figure represents the signal present
