DSC 5682/7 IDT70T3509M High-Speed 2.5V 1024K x 36 Dual-Port Synchronous Static RAM Commercial Temperature Range Description: The IDT70T3509M is a high-speed 1024K x 36 bit synchronous Dual-Port RAM. The memory array utilizes Dual-Port memory cells to allow simultaneous access of any address from both ports. Registers on control, data, and address inputs provide minimal setup and hold times. The timing latitude provided by this approach allows systems to be designed with very short cycle times. With an input data register, the IDT70T3509M has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode. The 70T3509M can support an operating voltage of either 3.3V or 2.5V on one or both ports, controllable by the OPT pins. The power supply for the core of the device (VDD) is at 2.5V. 6.42 2 IDT70T3509M High-Speed 2.5V 1024K x 36 Dual-Port Synchronous Static RAM Commercial Temperature Range Pin Configuration (1,2,3,4) 70T3509M BP BP-256(5,7) 256-Pin BGA Top View(6) 08/03/04 A1 NC B1 I/O18L C1 A2 TDI B2 NC C2 I/O18R I/O19L D1 D2 A3 A19L B3 TDO C3 VSS D3 A4 A 17L B4 A 18L C4 A16L D4 A5 A6 A 14L A11L B5 B6 A15L C5 A13L D5 A12L C6 A10L D6 A7 A 8L B7 A 9L C7 A7L D7 A9 A8 BE2L CE1L B9 B8 BE3L BE1L B10 B11 C10 C11 BE0L CLKL ADSL D9 D8 A11 A12 OEL CNTENL A5L CE0L R/WL REPEATL C9 C8 A10 D10 D11 B12 A4L C12 A6L D12 A13 A2L B13 A1L C13 A3L D13 A14 A0L B14 VDD C14 A15 A16 NC NC B16 B15 I/O17L NC C16 C15 OPTL I/O17R I/O16L D14 D16 D15 I/O20R I/O19R I/O20L PIPE/FTL VDDQL VDDQL VDDQR VDDQR VDDQL VDDQL VDDQR VDDQR VDD I/O15R I/O15L I/O16R E1 E2 E3 E4 I/O21R I/O21L I/O22L VDDQL F1 F2 F3 F4 E5 VDD F5 I/O23L I/O22R I/O23R VDDQL VDD G1 G2 G3 G4 I/O24R I/O24L I/O25L VDDQR H1 H2 H3 H4 G5 VSS H5 I/O26L I/O25R I/O26R VDDQR VSS J1 J2 J3 J4 I/O27L I/O28R I/O27R VDDQL K1 K2 K3 K4 I/O29R I/O29L I/O28L VDDQL L1 L2 L3 L4 J5 ZZR K5 VSS L5 I/O30L I/O31R I/O30R VDDQR VDD M1 M2 M3 M4 I/O32R I/O32L I/O31L VDDQR N1 N2 N3 N4 M5 VDD N5 E6 VDD F6 E7 INTL F7 NC G6 VSS H6 VSS J6 VSS K6 VSS L6 NC M6 VDD N6 NC G7 VSS H7 VSS J7 VSS K7 VSS L7 NC M7 INTR N7 E9 E8 VSS VSS F9 F8 VSS VSS G9 G8 VSS H8 VSS H9 VSS J8 VSS J9 VSS K8 VSS K9 VSS L8 VSS L9 VSS M8 VSS M9 VSS N8 VSS N9 E10 VSS F10 VSS G10 VSS H10 V SS J10 VSS K10 VSS L10 V SS M10 VSS N10 E11 VDD F11 VSS G11 VSS H11 VSS J11 VSS K11 VSS L11 VSS M11 VDD N11 E12 F12 P2 P3 I/O35R I/O34L TMS R1 I/O35L T1 NC R2 NC T2 TCK R3 P4 A16R R4 TRST A18R T3 A19R T4 A17R P5 A13R R5 A15R T5 A14R P6 A10R R6 A12R T6 A11R P7 A7R R7 A9R T7 A8R P8 P9 P10 P11 BE1R BE0R CLKR ADS R R8 R9 R10 R11 G12 VSS H12 VSS J12 T9 BE2R CE1R T10 T11 E16 E15 F13 F14 F15 F16 G13 G14 G15 G16 VDDQL I/O10L I/O11L I/O11R H13 H14 VDDQL I/O9R J13 J14 H16 H15 IO9L I/O10R J15 J16 ZZL VDDQR I/O8R I/O7R K12 VSS L12 VDD M12 VDD N12 P12 A6R R12 BE3R CE0R R/WR REPEATR A4R T8 E14 VDD VDDQR I/O12R I/O13R I/O12L I/O33L I/O34R I/O33R P IP E /FTR V DDQR VDDQR VDDQL VDDQL V DDQR VDDQR VDDQL VDDQL P1 E13 VDD VDDQR I/O13L I/O14L I/O14R T12 OER CNTENR A5R K13 K14 K15 I/O8L K16 VDDQR I/O6R I/O6L I/O7L L13 L14 VDDQL I/O5L M13 M14 VDDQL I/O3R N13 VDD P13 A3R R13 A1R T13 A2R N14 I/O2L P14 L15 L16 I/O4R I/O5R M16 M15 I/O3L I/O4L N16 N15 I/O1R I/O2R P15 P16 I/O0L I/O0R R14 OPTR T14 A 0R I/O1L R16 R15 NC T15 NC , T16 NC NC 5682 drw 02d NOTES: , 1.

VDD, OPTX, and VDDQX must be set to appropriate operating levels prior to applying inputs on the I/Os and controls for that port. 2. OPTX selects the operating voltage levels for the I/Os and controls on that port. If OPTX is set to VDD (2.5V), then that port's I/Os and controls will operate at 3.3V levels and VDDQX must be supplied at 3.3V. If OPT X is set to VSS (0V), then that port's I/Os and address controls will operate at 2.5V levels and VDDQX must be supplied at 2.5V. The OPT pins are independent of one another—both ports can operate at 3.3V levels, both can operate at 2.5V levels, or either can operate at 3.3V with the other at 2.5V. 3. When REPEATX is asserted, the counter will reset to the last valid address loaded via ADS X. 4. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when asserted. All static inputs, i.e., PL/FTx and OPTx and the sleep mode pins themselves (ZZx) are not affected during sleep mode. It is recommended that boundary scan not be operated during sleep mode. 5. Chip Enables and Byte Enables are double buffered when PL/FT = VIH, i.e., the signals take two cycles to deselect. 6.42 4 IDT70T3509M High-Speed 2.5V 1024K x 36 Dual-Port Synchronous Static RAM Commercial Temperature Range Truth Table I—Read/Write and Enable Control (1,2,3,4) OE CLK CE0 CE 1 BE3 BE2 BE1 BE0 R/W ZZ Byte 3 I/O27-35 Byte 2 I/O18-26 Byte 1 I/O9-17 Byte 0 I/O0-8 X ↑ H L X X X X X L High-Z High-Z High-Z High-Z X ↑ L L X X X X X X Active Active Active Active Not Allowed X ↑ H H X X X X X X Active Active Active Active Not Allowed X ↑ L H H H H H X L High-Z High-Z High-Z High-Z All Bytes Deselected X ↑ L H H H H L L L High-Z High-Z High-Z DIN Write to Byte 0 Only X ↑ L H H H L H L L High-Z High-Z DIN High-Z Write to Byte 1 Only X ↑ L H H L H H L L High-Z DIN High-Z High-Z Write to Byte 2 Only X ↑ L H L H H H L L DIN High-Z High-Z High-Z Write to Byte 3 Only X ↑ L H H H L L L L High-Z High-Z DIN DIN X ↑ L H L L H H L L DIN DIN High-Z High-Z X ↑ L H L L L L L L DIN DIN DIN DIN Write to All Bytes L ↑ L H H H H L H L High-Z High-Z High-Z DOUT Read Byte 0 Only L ↑ L H H H L H H L High-Z High-Z DOUT High-Z Read Byte 1 Only L ↑ L H H L H H H L High-Z DOUT High-Z High-Z Read Byte 2 Only L ↑ L H L H H H H L DOUT High-Z High-Z High-Z Read Byte 3 Only L ↑ L H H H L L H L High-Z High-Z DOUT DOUT Read Lower 2 Bytes Only L ↑ L H L L H H H L DOUT DOUT High-Z High-Z Read Upper 2 Bytes Only MODE Deselected–Power Down Write to Lower 2 Bytes Only Write to Upper 2 bytes Only L ↑ L H L L L L H L DOUT DOUT DOUT DOUT H ↑ X X X X X X X L High-Z High-Z High-Z High-Z Outputs Disabled X X X X X X X X X H High-Z High-Z High-Z High-Z Sleep Mode Read All Bytes 5682 tbl 02 NOTES: 1. "H" = V IH, "L" = VIL, "X" = Don't Care. 2. ADS, CNTEN, REPEAT = VIH. 3. OE and ZZ are asynchronous input signals. 4. It is possible to read or write any combination of bytes during a given access. A few representative samples have been illustrated here.

"H" = V IH, "L" = VIL, "X" = Don't Care. 2. Read and write operations are controlled by the appropriate setting of R/W, CE 0, CE1, BEn and OE. 3. Outputs configured in flow-through output mode: if outputs are in pipelined mode the data out will be delayed by one cycle. 4. ADS and REPEAT are independent of all other memory control signals including CE0, CE1 and BEn 5. The address counter advances if CNTEN = VIL on the rising edge of CLK, regardless of all other memory control signals including CE0, CE1, BEn. 6. When REPEAT is asserted, the counter will reset to the last valid address loaded via ADS. This value is not set at power-up: a known location should be loaded via ADS during initialization if desired. Any subsequent ADS access during operations will update the REPEAT address location. 7. Address A 19 must be managed as part of a full depth counter implementation using the IDT70T3509M. For physical addresses 00000H through 7FFFFH the value of a A19 is 0, while for physical addresses 80000H through FFFFF H the value of A19 is 1. The user needs to keep track of the device counter and make sure that A19 is actively driven from 0-to-1 or 1-to-0 and held as needed at the appropriate address boundaries for full depth counter operation and that A19 is in the appropriate state when using the REPEAT function. 6.42 5 IDT70T3509M High-Speed 2.5V 1024K x 36 Dual-Port Synchronous Static RAM Commercial Temperature Range Recommended Operating Temperature and Supply Voltage Grade Commercial Industrial (1) Ambient Temperature GND VDD 0OC to +70OC 0V 2.5V + 100mV -40OC to +85OC 0V 2.5V + 100mV NOTES: 1.

The Pipelined output parameters (tCYC2, tCD2) apply to either or both left and right ports when FT/PIPEX = VDD (2.5V). Flow-through parameters (tCYC1, tCD1) apply when FT/PIPE = Vss (0V) for that port. 2. All input signals are synchronous with respect to the clock except for the asynchronous Output Enable (OE), FT/PIPE and OPT. FT/PIPE and OPT should be treated as DC signals, i.e. steady state during operation. 3. These values are valid for either level of VDDQ (3.3V/2.5V).

Address A19 must be managed as part of a full depth counter implementation using the IDT70T3509M. For physical addresses 00000H through 7FFFFH the value of a A19 is 0, while for physical addresses 80000H through FFFFFH the value of A19 is 1. The user needs to keep track of the device counter and make sure that A19 is actively driven from 0-to-1 or 1-to-0 and held as needed at the appropriate address boundaries for full depth counter operation.

The "Internal Address" is equal to the "External Address" when ADS = VIL and equals the counter output when ADS = VIH. 4. No dead cycle exists during REPEAT operation. A READ or WRITE cycle may be coincidental with the counter REPEAT cycle: Address loaded by last valid ADS load will be accessed. For more information on REPEAT function refer to Truth Table II. A19 must be in the appropriate state when using the REPEAT function to guarantee the correct address location is loaded. 5. CNTEN = VIL advances Internal Address from ‘An’ to ‘An +1’. The transition shown indicates the time required for the counter to advance. The ‘An +1’Address is written to during this cycle. 6. For Pipelined Mode user should add 1 cycle latency for outputs as per timing waveform of read cycle for pipelined operations. 7. Address A19 must be managed as part of a full depth counter implementation using the IDT70T3509M. For physical addresses 00000H through 7FFFFH the value of a A19 is 0, while for physical addresses 80000H through FFFFFH the value of A19 is 1.

CE0 has to be deactivated (CE0 = VIH) one cycle prior to de-asserting ZZ (ZZx = V IL) and held for three cycles after de-asserting ZZ (ZZx = VIL). 5. The device must be in Read Mode (R/W High) when exiting sleep mode. Outputs are active but data is not valid until the following cycle. 6.42 18 IDT70T3509M High-Speed 2.5V 1024K x 36 Dual-Port Synchronous Static RAM Commercial Temperature Range Functional Description Sleep Mode The IDT70T3509M provides a true synchronous Dual-Port Static RAM interface. Registered inputs provide minimal set-up and hold times on address, data, and all critical control inputs. All internal registers are clocked on the rising edge of the clock signal, however, the self-timed internal write pulse width is independent of the cycle time. An asynchronous output enable is provided to ease asynchronous bus interfacing. Counter enable inputs are also provided to stall the operation of the address counters for fast interleaved memory applications. The combination of a HIGH on CE0 and a LOW on CE1 for one clock cycle will power down the internal circuitry to reduce static power consumption. Multiple chip enables allow easier banking of multiple IDT70T3509Ms for depth expansion configurations. Two cycles are required with CE0 LOW and CE1 HIGH to re-activate the outputs. The IDT70T3509M is equipped with an optional sleep or low power mode on both ports. The sleep mode pin on both ports is asynchronous and active high. During normal operation, the ZZ pin is pulled low. When ZZ is pulled high, the port will enter sleep mode where it will meet lowest possible power conditions. The sleep mode timing diagram shows the modes of operation: Normal Operation, No Read/Write Allowed and Sleep Mode. For normal operation all inputs must meet setup and hold times prior to sleep and after recovering from sleep. Clocks must also meet cycle high and low times during these periods. Three cycles prior to asserting ZZ (ZZx = VIH) and three cycles after de-asserting ZZ (ZZx = VIL), the device must be disabled via the chip enable pins. If a write or read operation occurs during these periods, the memory array may be corrupted. Validity of data out from the RAM cannot be guaranteed immediately after ZZ is asserted (prior to being in sleep). When exiting sleep mode, the device must be in Read mode (R/Wx = VIH)when chip enable is asserted, and the chip enable must be valid for one full cycle before a read will result in the output of valid data. During sleep mode the RAM automatically deselects itself. The RAM disconnects its internal clock buffer. The external clock may continue to run without impacting the RAMs sleep current (IZZ). All outputs will remain in high-Z state while in sleep mode. All inputs are allowed to toggle. The RAM will not be selected and will not perform any reads or writes. Width Expansion The IDT70T3509M can be used in applications requiring expanded width. Through combining the control signals, the devices can be grouped as necessary to accommodate applications needing 72-bits or wider. 6.42 19 IDT70T3509M High-Speed 2.5V 1024K x 36 Dual-Port Synchronous Static RAM Commercial Temperature Range JTAG Functionality and Configuration The IDT70T3509M is composed of four independent memory arrays, and thus cannot be treated as a single JTAG device in the scan chain. The four arrays (A, B, C and D) each have identical characteristics and commands but must be treated as separate entities in JTAG operations. Please refer to Figure 2. JTAG signaling must be provided serially to each array and utilize the information provided in the Identification Register Definitions, Scan Register Sizes, and System Interface Parameter tables. Specifically, all serial commands must be issued to the IDT70T3509M in the following sequence: Array D, Array C, Array B, Array A.
