JTAG boundary scan for BG and AJ package version Low-profile 119-bump 14-mm × 22-mm PBGA (Ball Grid Array) and 100-pin TQFP packages Functional Description The Cypress Synchronous Burst SRAM family employs high-speed, low-power CMOS designs using advanced triple-layer polysilicon, double-layer metal technology. Each memory cell consists of four transistors and two high-valued resistors. The CY7C1361A and CY7C1363A SRAMs integrate 262,144 × 36 and 524,288 × 18 SRAM cells with advanced synchronous peripheral circuitry and a two-bit counter for internal burst operation. All synchronous inputs are gated by registers controlled by a positive-edge-triggered Clock Input (CLK). The synchronous inputs include all addresses, all data inputs, address-pipelining Chip Enable (CE), depth-expansion Chip Enables (CE2 and CE2), burst control inputs (ADSC, ADSP, and ADV), Write Enables (BWa, BWb, BWc, BWd, and BWE), and global Write (GW). However, the CE2 chip enable input is only available for the TA package version. Asynchronous inputs include the Output Enable (OE) and burst mode control (MODE). The data outputs (Q), enabled by OE, are also asynchronous. Addresses and chip enables are registered with either Address Status Processor (ADSP) or Address Status Controller (ADSC) input pins. Subsequent burst addresses can be internally generated as controlled by the Burst Advance Pin (ADV). Address, data inputs, and Write controls are registered on-chip to initiate self-timed Write cycle. Write cycles can be one to four bytes wide as controlled by the Write control inputs. Individual byte Write allows individual byte to be written. BWa controls DQa. BWb controls DQb. BWc controls DQc. BWd controls DQd. BWa, BWb, BWc, and BWd can be active only with BWE being LOW. GW being LOW causes all bytes to be written. The x18 version only has 18 data inputs/outputs (DQa and DQb) along with BWa and BWb (no BWc, BWd, DQc, and DQd). For the TQFP AJ and the BGA package versions, four pins are used to implement JTAG test capabilities: Test Mode Select (TMS), Test Data-In (TDI), Test Clock (TCK), and Test Data-Out (TDO). The JTAG circuitry is used to serially shift data to and from the device. JTAG inputs use LVTTL/LVCMOS levels to shift data during this testing mode of operation. The TA package version does not offer the JTAG capability. The CY7C1361A and CY7C1363A operate from a +3.3V power supply. All inputs and outputs are LVTTL-compatible.

Document #: 38-05259 Rev. *C Page 9 of 27 CY7C1361A CY7C1363A IEEE 1149.1 Serial Boundary Scan (JTAG) Overview This device incorporates a serial boundary scan test access port (TAP). This port is designed to operate in a manner consistent with IEEE Standard 1149.1-1990 (commonly referred to as JTAG), but does not implement all of the functions required for IEEE 1149.1 compliance. Certain functions have been modified or eliminated because their implementation places extra delays in the critical speed path of the device. Nevertheless, the device supports the standard TAP controller architecture (the TAP controller is the state machine that controls the TAPs operation) and can be expected to function in a manner that does not conflict with the operation of devices with IEEE Standard 1149.1 compliant TAPs. The TAP operates using LVTTL/ LVCMOS logic level signaling. Disabling the JTAG Feature It is possible to use this device without using the JTAG feature. To disable the TAP controller without interfering with normal operation of the device, TCK should be tied LOW (VSS) to prevent clocking the device. TDI and TMS are internally pulled up and may be unconnected. They may alternately be pulled up to VCC through a resistor. TDO should be left unconnected. Upon power-up the device will come up in a reset state which will not interfere with the operation of the device. Test Access Port TCK—Test Clock (INPUT) Clocks all TAP events. All inputs are captured on the rising edge of TCK and all outputs propagate from the falling edge of TCK. TMS—Test Mode Select (INPUT) The TMS input is sampled on the rising edge of TCK. This is the command input for the TAP controller state machine. It is allowable to leave this pin unconnected if the TAP is not used. The pin is pulled up internally, resulting in a logic HIGH level. TDI—Test Data In (INPUT) The TDI input is sampled on the rising edge of TCK. 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 register (refer to Figure 1, TAP Controller State Diagram). It is allowable to leave this pin unconnected if it is not used in an application. The pin is pulled up internally, resulting in a logic HIGH level. TDI is connected to the Most Significant Bit (MSB) of any register (see Figure 2). TDO—Test Data Out (OUTPUT) The TDO output pin is used to serially clock data-out from the registers. The output that is active depending on the state of the TAP state machine (refer to Figure 1, TAP Controller State Diagram). Output changes in response to the falling edge of TCK. This is the output side of the serial registers placed between TDI and TDO. TDO is connected to the Least Significant Bit (LSB) of any register (see Figure 2). Document #: 38-05259 Rev. *C Performing a TAP Reset The TAP circuitry does not have a reset pin (TRST, which is optional in the IEEE 1149.1 specification). A RESET can be performed for the TAP controller by forcing TMS HIGH (VCC) for five rising edges of TCK and pre-loads the instruction register with the IDCODE command. This type of reset does not affect the operation of the system logic. The reset affects test logic only. At power-up, the TAP is reset internally to ensure that TDO is in a High-Z state. TAP Registers Overview The various TAP registers are selected (one at a time) via the sequences of ones and zeros input to the TMS pin as the TCK is strobed. Each of the TAPs registers are serial shift registers that capture serial input data on the rising edge of TCK and push serial data out on subsequent falling edge of TCK. When a register is selected, it is connected between the TDI and TDO pins. Instruction Register The instruction register holds the instructions that are executed by the TAP controller when it is moved into the run test/idle or the various data register states. The instructions are three bits long. The register can be loaded when it is placed between the TDI and TDO pins. The parallel outputs of the instruction register are automatically preloaded with the IDCODE instruction upon power-up or whenever the controller is placed in the test-logic reset state. When the TAP controller is in the Capture-IR state, the two least significant bits of the serial instruction register are loaded with a binary “01” pattern to allow for fault isolation of the board-level serial test data path. Bypass Register The bypass register is a single-bit register that can be placed between TDI and TDO. It allows serial test data to be passed through the device TAP to another device in the scan chain with minimum delay. The bypass register is set LOW (VSS) when the BYPASS instruction is executed. Boundary Scan Register The Boundary Scan register is connected to all the input and bidirectional I/O pins (not counting the TAP pins) on the device. This also includes a number of NC pins that are reserved for future needs. There are a total of 70 bits for the x36 device and 51 bits for the x18 device. The boundary scan register, under the control of the TAP controller, is loaded with the contents of the device I/O ring when the controller is in Capture-DR state and then is placed between the TDI and TDO pins when the controller is moved to Shift-DR state. The EXTEST, SAMPLE/PRELOAD and SAMPLE-Z instructions can be used to capture the contents of the I/O ring. The Boundary Scan Order table describes the order in which the bits are connected. The first column defines the bit’s position in the boundary scan register. The MSB of the register is connected to TDI, and LSB is connected to TDO. The second column is the signal name, the third column is the TQFP pin number, and the fourth column is the BGA bump number. Page 10 of 27 CY7C1361A CY7C1363A Identification (ID) Register The ID Register is a 32-bit register that is loaded with a device and vendor specific 32-bit code when the controller is put in Capture-DR state with the IDCODE command loaded in the instruction register. The register is then placed between the TDI and TDO pins when the controller is moved into Shift-DR state. Bit 0 in the register is the LSB and the first to reach TDO when shifting begins. The code is loaded from a 32-bit on-chip ROM. It describes various attributes of the device as described in the Identification Register Definitions table. TAP Controller Instruction Set Overview There are two classes of instructions defined in the IEEE Standard 1149.1-1990; the standard (public) instructions and device specific (private) instructions. Some public instructions are mandatory for IEEE 1149.1 compliance. Optional public instructions must be implemented in prescribed ways. Although the TAP controller in this device follows the IEEE 1149.1 conventions, it is not IEEE 1149.1-compliant because some of the mandatory instructions are not fully implemented. The TAP on this device may be used to monitor all input and I/O pads, but can not be used to load address, data, or control signals into the device or to preload the I/O buffers. In other words, the device will not perform IEEE 1149.1 EXTEST, INTEST, or the preload portion of the SAMPLE/PRELOAD command. When the TAP controller is placed in Capture-IR state, the two least significant bits of the instruction register are loaded with 01. When the controller is moved to the Shift-IR state the instruction is serially loaded through the TDI input (while the previous contents are shifted out at TDO). For all instructions, the TAP executes newly loaded instructions only when the controller is moved to Update-IR state. The TAP instruction sets for this device are listed in the following tables. EXTEST EXTEST is an IEEE 1149.1 mandatory public instruction. It is to be executed whenever the instruction register is loaded with all 0s. EXTEST is not implemented in this device. The TAP controller does recognize an all-0 instruction. When an EXTEST instruction is loaded into the instruction register, the device responds as if a SAMPLE/PRELOAD instruction has been loaded. There is one difference between two instructions. Unlike SAMPLE/PRELOAD instruction, EXTEST places the device outputs in a High-Z state. IDCODE The IDCODE instruction causes a vendor-specific, 32-bit code to be loaded into the ID register when the controller is in Document #: 38-05259 Rev. *C Capture-DR mode and places the ID register between the TDI and TDO pins in Shift-DR mode. The IDCODE instruction is the default instruction loaded in the instruction upon power-up and at any time the TAP controller is placed in the test-logic reset state. SAMPLE-Z If the High-Z instruction is loaded in the instruction register, all output pins are forced to a High-Z state and the boundary scan register is connected between TDI and TDO pins when the TAP controller is in a Shift-DR state. SAMPLE/PRELOAD SAMPLE/PRELOAD is an IEEE 1149.1 mandatory instruction. The PRELOAD portion of the command is not implemented in this device, so the device TAP controller is not fully IEEE 1149.1-compliant. When the SAMPLE/PRELOAD instruction is loaded in the instruction register and the TAP controller is in the Capture-DR state, a snap shot of the data in the device’s input and I/O buffers is loaded into the boundary scan register. Because the device system clock(s) are independent from the TAP clock (TCK), it is possible for the TAP to attempt to capture the input and I/O ring contents while the buffers are in transition (i.e., in a metastable state). Although allowing the TAP to sample metastable inputs will not harm the device, repeatable results can not be expected. To guarantee that the boundary scan register will capture the correct value of a signal, the device input signals must be stabilized long enough to meet the TAP controller’s capture set-up plus hold time (tCS plus tCH). The device clock input(s) need not be paused for any other TAP operation except capturing the input and 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 pins. Because the PRELOAD portion of the command is not implemented in this device, moving the controller to the Update-DR state with the SAMPLE/PRELOAD instruction loaded in the instruction register has the same effect as the Pause-DR command. BYPASS When the BYPASS instruction is loaded in the instruction register and the TAP controller is in the Shift-DR state, the bypass register is placed between TDI and TDO. This allows the board level scan path to be shortened to facilitate testing of other devices in the scan path. Reserved Do not use these instructions. They are reserved for future use.
