cy7c1386d, cy7c1386f cy7c1387d, cy7c1387f document number: 38-05545 rev. *h page 8 of 36 functional overview all synchronous inputs pass through input registers controlled by the rising edge of the clock. all data outputs pass through output registers controlled by the ri sing edge of the clock. the cy7c1386d/cy7c1387d/cy7c1386f/cy7c1387f supports secondary cache in systems using either a linear or interleaved burst sequence. the interleaved burst order supports pentium ? and i486 ? processors. the linear burst sequence is suited for processors that use a linear burst sequence. the burst order is user selectable, and is determined by sampling the mode input. accesses can be initiated with either the processor address strobe (adsp ) or the controller address strobe (adsc ). address advancement through the burst sequence is controlled by the adv input. a two-bit on-chip wraparound burst counter captures the first address in a burst sequence and automatically increments the address for the rest of the burst access. byte write operations are qualified with the byte write enable (bwe ) and byte write select (bw x ) inputs. a global write enable (gw ) overrides all byte write inputs and writes data to all four bytes. all writes are simplified with on-chip synchronous self timed write circuitry. synchronous chip selects ce 1 , ce 2 , ce 3 [5] and an asynchronous output enable (oe ) provide for easy bank selection and output tristate control. adsp is ignored if ce 1 is high. single read accesses this access is initiated when the following conditions are satisfied at clock rise: (1) adsp or adsc is asserted low, (2) chip selects are all asserted active, and (3) the write signals (gw , bwe ) are all deasserted high. adsp is ignored if ce 1 is high. the address presented to the address inputs is stored into the address advancement logic and the address register while being presented to the memory core. the corresponding data is allowed to propagate to the input of the output registers. at the rising edge of the next clock the data is allowed to propagate through the output register and onto the data bus within t co if oe is active low. the only exception occurs when the sram is emerging from a deselected state to a selected state, its outputs are always tristated during the fi rst cycle of the access. after the first cycle of the access, the ou tputs are contro lled by the oe signal. consecutive single read cycles are supported. the cy7c1386d/cy7c1387d/cy7c1386f/cy7c1387f is a double cycle deselect part. after t he sram is deselected at clock rise by the chip select and either adsp or adsc signals, its output tristates immediately after the next clock rise. mode input- static selects burst order . when tied to gnd selects linear burst sequence. when tied to v dd or left floating selects interleaved burst sequence. this is a strap pin and must remain static during device operation. mode pin has an internal pull up. tdo jtag serial output synchronous serial data-out to the jtag circuit . delivers data on the negative edge of tck. if the jtag feature is not used, this pin must be disconnected. th is pin is not available on tqfp packages. tdi jtag serial input synchronous serial data-in to the jtag circuit . sampled on the rising edge of tc k. if the jtag feature is not used, this pin can be disconnected or connected to v dd . this pin is not available on tqfp packages. tms jtag serial input synchronous serial data-in to the jtag circuit . sampled on the rising edge of tc k. if the jtag feature is not used, this pin can be disconnected or connected to v dd . this pin is not available on tqfp packages. tck jtag- clock clock input to th e jtag circuitry . if the jtag feature is not used, this pin must be connected to v ss . this pin is not available on tqfp packages. nc ? no connects . not internally connected to the die. nc/(36 m, 72 m, 144 m, 288 m, 576 m, 1 g) ? these pins are not connected. they are used for expansion up to 36 m, 72 m, 144 m, 288 m, 576 m, and 1g densities. pin definitions (continued) name i/o description note 5. ce 3 and ce 2 are for 100-pin tqfp and 165-ball fbga packages only. 119-ball bga is offered only in single chip enable.

pattern to allow for fault isolation of the board-level serial test data path. bypass register to save time when serially shifting data through registers, it is sometimes advantageous to skip certain chips. the bypass register is a single-bit register that can be placed between the tdi and tdo balls. this allows data to be shifted through the sram with minimal delay. the by pass register is set low (v ss ) when the bypass instruction is executed. boundary scan register the boundary scan register is connected to all the input and bidirectional balls on the sram. the boundary scan register is loaded with the contents of the ram input and output ring when the tap controller is in the capture-dr state and is then placed between the tdi and tdo balls when the controller is moved to the shift-dr state. the extest, sample/preload, and sa mple z instructions can be used to capture the contents of the input and output ring. the boundary scan order tables show the order in which the bits are connected. each bit corresponds to one of the bumps on the sram package. the msb of the register is connected to tdi, and the lsb is connected to tdo. identification (id) register the id register is loaded with a vendor specific 32-bit code during the capture-dr state when the idcode command is loaded in the instruction register . the idcode is hardwired into the sram and can be shifted out when the tap controller is in the shift-dr state. the id regist er has a vendor code and other information described in the identification register definitions on page 18 . tap instruction set overview eight different instructions are possible with the three bit instruction register. all combinations are listed in identification codes on page 18 . three of these instru ctions are listed as reserved and must not be used. the other five instructions are described in detail below. instructions are loaded into the tap controller during the shift-ir state when the instruction register is placed between tdi and tdo. during this state, instructions are shifted through the instruction register through the tdi and tdo balls. to execute [+] feedback
