CY7C1386D, CY7C1386F CY7C1387D, CY7C1387F 18-Mbit (512 K × 36/1 M × 18) Pipelined DCD Sync SRAM 18-Mbit (512 K × 36/1 M × 18) Pipelined DCD Sync SRAM Features ■ ■ ■ ■ ■ ■ ■ ■ Functional Description The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F SRAM[1] integrates 512 K × 36/1 M × 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 (CE1), depth expansion chip enables (CE2 and CE3 [2]), burst control inputs (ADSC, ADSP, and ADV), write enables (BWX, and BWE), and global write (GW). Asynchronous inputs include the output enable (OE) and the ZZ pin. Addresses and chip enables are registered at rising edge of clock when either address strobe processor (ADSP) or address strobe controller (ADSC) are active. Subsequent burst addresses can be internally generated as controlled by the advance pin (ADV). Address, data inputs, and write controls are registered on-chip to initiate a self timed write cycle.This part supports byte write operations (see on page 4 and Truth Table on page 11 for further details). Write cycles can be one to four bytes wide as controlled by the byte write control inputs. GW active LOW causes all bytes to be written. This device incorporates an additional pipelined enable register which delays turning off the output buffers an additional cycle when a deselect is executed.This feature allows depth expansion without penalizing system performance. The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F operates from a +3.3 V core power supply while all outputs operate with a +3.3 V or +2.5 V supply. All inputs and outputs are JEDEC-standard and JESD8-5-compatible. Supports bus operation up to 250 MHz Available speed grades are 250, 200, and 167 MHz Registered inputs and outputs for pipelined operation Optimal for performance (double-cycle deselect) Depth expansion without wait state 3.3 V core power supply (VDD) 2.5 V or 3.3 V I/O power supply (VDDQ) Fast clock-to-output times ❐ 2.6 ns (for 250 MHz device) Provides high performance 3-1-1-1 access rate User selectable burst counter supporting Intel Pentium Interleaved or linear burst sequences Separate processor and controller address strobes Synchronous self-timed writes Asynchronous output enable CY7C1386D/CY7C1387D available in JEDEC-standard Pb-free 100-pin TQFP, Pb-free and non Pb-free 165-ball FBGA package.

TDI TMS TCK NC NC/(36 M, 72 M, 144 M, 288 M, 576 M, 1 G) 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 rising 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 (BWX) 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 CE1, CE2, CE3 [5] and an asynchronous output enable (OE) provide for easy bank selection and output tristate control. ADSP is ignored if CE1 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 CE1 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 tCO 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 first cycle of the access. After the first cycle of the access, the outputs are controlled by the OE signal. Consecutive single read cycles are supported. The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F is a double cycle deselect part. After the 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. Note 5. CE3 and CE2 are for 100-pin TQFP and 165-ball FBGA packages only. 119-ball BGA is offered only in Single Chip Enable. Document Number: 38-05545 Rev. *H Page 8 of 36 [+] Feedback CY7C1386D, CY7C1386F CY7C1387D, CY7C1387F Single Write Accesses Initiated by ADSP This access is initiated when both of the following conditions are satisfied at clock rise: (1) ADSP is asserted LOW and (2) chip select is asserted active. The address presented is loaded into the address register and the address advancement logic while being delivered to the memory core. The write signals (GW, BWE, and BWX) and ADV inputs are ignored during this first cycle. ADSP triggered write accesses require two clock cycles to complete. If GW is asserted LOW on the second clock rise, the data presented to the DQx inputs is written into the corresponding address location in the memory core. If GW is HIGH, the write operation is controlled by BWE and BWX signals. The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F provides byte write capability that is described in the write cycle description table. Asserting the byte write enable input (BWE) with the selected byte write input, selectively writes to the desired bytes. Bytes not selected during a byte write operation remains unaltered. A synchronous self timed write mechanism has been provided to simplify the write operations. The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F is a common I/O device, the output enable (OE) must be deasserted HIGH before presenting data to the DQ inputs. This tristates the output drivers. As a safety precaution, DQ are automatically tristated whenever a write cycle is detected, regardless of the state of OE. core. If a byte write is conducted, only the selected bytes are written. Bytes not selected during a byte write operation remains unaltered. A synchronous self timed write mechanism has been provided to simplify the write operations. The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F is a common I/O device, the output enable (OE) must be deasserted HIGH before presenting data to the DQX inputs. This tristates the output drivers. As a safety precaution, DQX are automatically tristated whenever a write cycle is detected, regardless of the state of OE. Burst Sequences The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F provides a two-bit wraparound counter, fed by A[1:0], that implements either an interleaved or linear burst sequence. The interleaved burst sequence is designed specifically to support Intel Pentium applications. The linear burst sequence is designed to support processors that follow a linear burst sequence. The burst sequence is user selectable through the MODE input. Asserting ADV LOW at clock rise automatically increments the burst counter to the next address in the burst sequence. Both read and write burst operations are supported. Sleep Mode The ZZ input pin is an asynchronous input. Asserting ZZ places the SRAM in a power conservation sleep mode. Two clock cycles are required to enter into or exit from this sleep mode. While in this mode, data integrity is guaranteed. Accesses pending when entering the sleep mode are not considered valid nor is the completion of the operation guaranteed. The device must be deselected prior to entering the sleep mode. CEs, ADSP, and ADSC must remain inactive for the duration of tZZREC after the ZZ input returns LOW. Single Write Accesses Initiated by ADSC ADSC write accesses are initiated when the following conditions are satisfied: (1) ADSC is asserted LOW, (2) ADSP is deasserted HIGH, (3) chip select is asserted active, and (4) the appropriate combination of the write inputs (GW, BWE, and BWX) are asserted active to conduct a write to the desired byte(s).

This part is fully compliant with 1149.1. The TAP operates using JEDEC-standard 3.3 V or 2.5 V I/O logic levels. The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F contains a TAP controller, instruction register, boundary scan register, bypass register, and ID register. instruction register. Data is serially loaded into the TDI ball on the rising edge of TCK. Data is output on the TDO ball on the falling edge of TCK. Instruction Register Three-bit instructions can be serially loaded into the instruction register. This register is loaded when it is placed between the TDI and TDO balls as shown in the TAP Controller Block Diagram on page 15. Upon power-up, the instruction register is loaded with the IDCODE instruction. It is also loaded with the IDCODE instruction if the controller is placed in a reset state as described in the previous section. When the TAP controller is in the Capture-IR state, the two least significant bits are loaded with a binary ‘01’ 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 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 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 SAMPLE 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 register has a vendor code and other information described in the Identification Register Definitions on page 18. Disabling the JTAG Feature It is possible to operate the SRAM without using the JTAG feature. To disable the TAP controller, TCK must be tied LOW (VSS) to prevent clocking of the device. TDI and TMS are internally pulled up and may be unconnected. They may alternately be connected to VDD through a pull up resistor. TDO can be left unconnected. Upon power-up, the device comes up in a reset state which does not interfere with the operation of the device. Test Access Port (TAP) Test Clock (TCK) The test clock is used only with the TAP controller. All inputs are captured on the rising edge of TCK. All outputs are driven from the falling edge of TCK. Test Mode Select (TMS) The TMS input is used to give commands to the TAP controller and is sampled on the rising edge of TCK. This pin may be left unconnected if the TAP is not used. The ball is pulled up internally, resulting in a logic HIGH level. Test Data-In (TDI) The TDI ball is used to serially input information into the registers and can be connected to the input of any of the registers. The register between TDI and TDO is chosen by the instruction that is loaded into the TAP instruction register. TDI is internally pulled up and can be unconnected if the TAP is unused in an application. TDI is connected to the most significant bit (MSB) of any register. Test Data-Out (TDO) The TDO output ball is used to serially clock data out from the registers. The output is active depending upon the current state of the TAP state machine. The output changes on the falling edge of TCK. TDO is connected to the least significant bit (LSB) of any register. 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 instructions 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 Performing a TAP Reset A Reset is performed by forcing TMS HIGH (VDD) for five rising edges of TCK. This Reset does not affect the operation of the SRAM and may be performed while the SRAM is operating. At power-up, the TAP is reset internally to ensure that TDO comes up in a high Z state. TAP Registers Registers are connected between the TDI and TDO balls and allow data to be scanned into and out of the SRAM test circuitry. Only one register can be selected at a time through the Document Number: 38-05545 Rev. *H Page 13 of 36 [+] Feedback CY7C1386D, CY7C1386F CY7C1387D, CY7C1387F the instruction after it is shifted in, the TAP controller needs to be moved into the Update-IR state. EXTEST The EXTEST instruction enables the preloaded data to be driven out through the system output pins. This instruction also selects the boundary scan register to be connected for serial access between the TDI and TDO in the Shift-DR controller state. IDCODE The IDCODE instruction causes a vendor specific 32-bit code to be loaded into the instruction register. It also places the instruction register between the TDI and TDO balls and allows the IDCODE to be shifted out of the device when the TAP controller enters the Shift-DR state. The IDCODE instruction is loaded into the instruction register upon power-up or whenever the TAP controller is given a test logic reset state. SAMPLE Z The SAMPLE Z instruction causes the boundary scan register to be connected between the TDI and TDO balls when the TAP controller is in a Shift-DR state. The SAMPLE Z command places all SRAM outputs into a high Z state. SAMPLE/PRELOAD SAMPLE/PRELOAD is a 1149.1 mandatory instruction. When the SAMPLE/PRELOAD instructions are loaded into the instruction register and the TAP controller is in the Capture-DR state, a snapshot of data on the input and output pins is captured in the boundary scan register. The user must be aware that the TAP controller clock can only operate at a frequency up to 20 MHz, while the SRAM clock operates more than an order of magnitude faster. As there is a large difference in the clock frequencies, it is possible that during the Capture-DR state, an input or output undergoes a transition. The TAP may then try to capture a signal while in transition (metastable state). This does not harm the device, but there is no guarantee as to the value that is captured. Repeatable results may not be possible. To guarantee that the boundary scan register captures the correct value of a signal, the SRAM signal must be stabilized long enough to meet the TAP controller’s capture setup plus hold times (tCS and tCH). The SRAM clock input might not be captured correctly if there is no way in a design to stop (or slow) the clock during a SAMPLE/PRELOAD instruction. If this is an issue, it is still possible to capture all other signals and simply ignore the value of the CK and CK captured in the boundary scan register. After the data is captured, it is possible to shift out the data by putting the TAP into the Shift-DR state. This places the boundary scan register between the TDI and TDO pins. PRELOAD allows an initial data pattern to be placed at the latched parallel outputs of the boundary scan register cells prior to the selection of another boundary scan test operation. The shifting of data for the SAMPLE and PRELOAD phases can occur concurrently when required; that is, while data captured is shifted out, the preloaded data can be shifted in. BYPASS When the BYPASS instruction is loaded in the instruction register and the TAP is placed in a Shift-DR state, the bypass register is placed between the TDI and TDO balls. The advantage of the BYPASS instruction is that it shortens the boundary scan path when multiple devices are connected together on a board. EXTEST Output Bus Tristate IEEE Standard 1149.1 mandates that the TAP controller be able to put the output bus into a tristate mode. The boundary scan register has a special bit located at bit #85 (for 119-ball BGA package) or bit #89 (for 165-ball FBGA package). When this scan cell, called the “extest output bus tristate,” is latched into the preload register during the Update-DR state in the TAP controller, it directly controls the state of the output (Q-bus) pins, when the EXTEST is entered as the current instruction. When HIGH, it enables the output buffers to drive the output bus. When LOW, this bit places the output bus into a high Z condition. This bit can be set by entering the SAMPLE/PRELOAD or EXTEST command, and then shifting the desired bit into that cell, during the Shift-DR state. During Update-DR, the value loaded into that shift-register cell latches into the preload register. When the EXTEST instruction is entered, this bit directly controls the output Q-bus pins. Note that this bit is preset HIGH to enable the output when the device is powered-up, and also when the TAP controller is in the Test-Logic-Reset state.

This part has a voltage regulator internally; tPOWER is the time that the power needs to be supplied above VDD(minimum) initially before a read or write operation can be initiated. 27. tCHZ, tCLZ,tOELZ, and tOEHZ are specified with AC test conditions shown in (b) of Figure 4 on page 23. Transition is measured ±200 mV from steady-state voltage. 28. At any voltage and temperature, tOEHZ is less than tOELZ and tCHZ is less than tCLZ to eliminate bus contention between SRAMs when sharing the same data bus. These specifications do not imply a bus contention condition, but reflect parameters guaranteed over worst case user conditions. Device is designed to achieve high Z prior to low Z under the same system conditions. 29. This parameter is sampled and not 100% tested.
