Rev.0.0, Jan. 2003, page 4 of 30 HM66AEB36104/18204/9404 Pin Descriptions Name I/O type Descriptions SAn SA0 SA1 Input Synchronous address inputs: These inputs are registered and must meet the setup and hold times around the rising edge of K. Ball 2A is reserved for the next higher-order address input on future devices. All transactions operate on burst-of-four words (two clock periods of bus activity). SA0 and SA1 are used as the lowest two address bits for burst READ and burst WRITE operations permitting a random burst start address on ×18 and ×36 devices. These inputs are ignored when device is deselected or once burst operation is in progress. LD Input Synchronous load: This input is brought low when a bus cycle sequence is to be defined. This definition includes address and READ / WRITE direction. All transactions operate on a burst-of-four data (two clock periods of bus activity). R/W Input Synchronous read / write Input: When LD is low, this input designates the access type (READ when R/W is high, WRITE when R/W is low) for the loaded address. R/W must meet the setup and hold times around the rising edge of K. BW BWn Input Synchronous byte writes: When low, these inputs cause their respective byte to be registered and written during WRITE cycles. These signals must meet setup and hold times around the rising edges of K and K for each of the two rising edges comprising the WRITE cycle. See Byte Write Truth Table for signal to data relationship. K, K Input Input clock: This input clock pair registers address and control inputs on the rising edge of K, and registers data on the rising edge of K and the rising edge of K. K is ideally 180 degrees out of phase with K. All synchronous inputs must meet setup and hold times around the clock rising edges. C, C Input Output clock: This clock pair provides a user-controlled means of tuning device output data. The rising edge of C is used as the output timing reference for second and fourth output data. The rising edge of C is used as the output reference for first and third output data. Ideally, C is 180 degrees out of phase with C. C and C may be tied high to force the use of K and K as the output reference clocks instead of having to provide C and C clocks. If tied high, C and C must remain high and not to be toggled during device operation. DOFF Input DLL disable: When low, this input causes the DLL to be bypassed for stable, lowfrequency operation. ZQ Input Output impedance matching input: This input is used to tune the device outputs to the system data bus impedance. DQ and CQ output impedance are set to 0.2 × RQ, where RQ is a resistor from this ball to ground. Alternately, this ball can be connected directly to VDDQ, which enables the minimum impedance mode. This ball cannot be connected directly to VSS or left unconnected. TMS TDI Input IEEE1149.1 test inputs: 1.8 V I/O levels. These balls may be left not connected if the JTAG function is not used in the circuit. TCK Input IEEE1149.1 clock input: 1.8 V I/O levels. This ball must be tied to VSS if the JTAG function is not used in the circuit. Rev.0.0, Jan. 2003, page 5 of 30 HM66AEB36104/18204/9404 Name I/O type Descriptions DQn Input/ output CQ, CQ Output Synchronous echo clock outputs: The edges of these outputs are tightly matched to the synchronous data outputs and can be used as a data valid indication. These signals run freely and do not stop when DQ tri-states. TDO Output IEEE 1149.1 test output: 1.8 V I/O level. VDD Supply Power supply: 1.8 V nominal. See DC Characteristics and Operating Conditions for range. VDDQ Supply Power supply: Isolated output buffer supply. Nominally 1.5 V. 1.8 V is also permissible. See DC Characteristics and Operating Conditions for range. VSS Supply Power supply: Ground VREF HSTL input reference voltage: Nominally VDDQ/2. Provides a reference voltage for the input buffers. NC No connect: These signals are internally connected and appear in the JTAG scan chain as the logic level applied to the ball sites. These signals may be connected to ground to improve package heat dissipation. Note: Synchronous data I/Os: Input data must meet setup and hold times around the rising edges of K and K. Output data is synchronized to the respective C and C data clocks, or to the respective K and K if C and C are tied high. The ×9 device uses DQ0 to DQ8. Remaining signals are NC. The ×18 device uses DQ0 to DQ17. Remaining signals are NC. The ×36 device uses DQ0 to DQ35. NC signals are read in the JTAG scan chain as the logic level applied to the ball site. 1. All power supply and ground balls must be connected for proper operation of the device.

Data inputs are registered at K and K rising edges. Data outputs are delivered at C and C rising edges, except if C and C are high, then data outputs are delivered at K and K rising edges. All control inputs in the truth table must meet setup/hold times around the rising edges (low to high) of K. ALL control inputs are registered during the rising edge of K. This device contains circuitry that will ensure the outputs will be in high-Z during power-up. Refer to state diagram and timing diagrams for clarification. It is recommended that (K) = /(K) = (C) = /(C) when clock is stopped. This is not essential, but permits most rapid restart by overcoming transmission line charging symmetrically. “A+0” refers to the address input during a WRITE or READ cycle. “A+1”, “A+2” and “A+3” refer to the internal burst address in accordance with the linear burst sequence.

Rev.0.0, Jan. 2003, page 19 of 30 HM66AEB36104/18204/9404 JTAG Specification These products support a limited set of JTAG functions as in IEEE standard 1149.1. 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 1, and may be left unconnected. But they may also be tied to VDD through a 1kΩ resistor. TDO should be left unconnected. Test Access Port (TAP) Pins Symbol I/O Pin assignments Description TCK 2R Test clock input. All inputs are captured on the rising edge of TCK and all outputs propagate from the falling edge of TCK. TMS 10R Test mode select. This is the command input for the TAP controller state machine. TDI 11R Test data input. This is the input side of the serial registers placed between TDI and TDO. The register placed between TDI and TDO is determined by the state of the TAP controller state machine and the instruction that is currently loaded in the TAP instruction. TDO 1R Test data output. Output changes in response to the falling edge of TCK. This is the output side of the serial registers placed between TDI and TDO. Note: The device does not have TRST (TAP reset). The Test-Logic Reset state is entered while TMS is held high for five rising edges of TCK. The TAP controller state is also reset on SRAM POWER-UP.

Boundary scan register cells at output balls are used to apply test vectors, while those at input balls capture test results. Typically, the first test vector to be applied using the EXTEST instruction will be shifted into the boundary scan register using the PRELOAD instruction. Thus, during the Update-IR state of EXTEST, the output drive is turned on and the PRELOAD data is driven onto the output balls. 0 0 1 IDCODE The IDCODE instruction causes the ID ROM to be loaded into the ID register when the controller is in capture-DR mode and places the ID register between the TDI and TDO balls in shiftDR mode. The IDCODE instruction is the default instruction loaded in at power up and any time the controller is placed in the Test-Logic-Reset state. 0 1 0 SAMPLE-Z If the SAMPLE-Z instruction is loaded in the instruction register, all RAM outputs are forced to an inactive drive state (high-Z, except CQ, CQ ball) and the boundary register is connected between TDI and TDO when the TAP controller is moved to the shift-DR state. 0 1 1 RESERVED These instructions are not implemented but are reserved for future use. Do not use these instructions. 1 0 0 SAMPLE (-PRELOAD) When the SAMPLE instruction is loaded in the instruction register, moving the TAP controller into the capture-DR state loads the data in the RAMs input and I/O buffers into the boundary scan register. Because the RAM clock(s) are independent from the TAP clock (TCK) it is possible for the TAP to attempt to capture the I/O ring contents while the input buffers are in transition (i.e., in a metastable state). Although allowing the TAP to SAMPLE metastable input will not harm the device, repeatable results cannot be expected. RAM input signals must be stabilized for long enough to meet the TAPs input data capture setup plus hold time (tCS plus tCH). The RAMs clock inputs need not be paused for any other TAP operation except capturing the I/O ring contents into the boundary scan register. Moving the controller to shift-DR state then places the boundary scan register between the TDI and TDO balls. 1 0 1 RESERVED 1 1 0 RESERVED 1 1 1 BYPASS Notes 1, 2 The BYPASS instruction is loaded in the instruction register when the bypass register is placed between TDI and TDO. This occurs when the TAP controller is moved to the shift-DR state. This allows the board level scan path to be shortened to facilitate testing of other devices in the scan path. Notes: 1. Data in output register is not guaranteed if EXTEST instruction is loaded. 2. After performing EXTEST, power-up conditions are required in order to return part to normal operation.
