DSC-5652/6 IDT70T3339/19/99S High-Speed 2.5V 512/256/128K x 18 Dual-Port Static RAM Industrial and Commercial Temperature Ranges Description: The IDT70T3339/19/99 is a high-speed 512/256/128k x 18 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 IDT70T3339/19/99 has been optimized for applications having unidirec- tional 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 IDT70T3339/19/99 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 IDT70T3339/19/99S High-Speed 2.5V 512/256/128K x 18 Dual-Port Static RAM Industrial and Commercial Temperature Ranges Pin Configuration (3,4,5,6,9) 70T3339/19/99BC BC-256(8) 256-Pin BGA Top View(9) 01/13/03 A1 NC B1 INTL C1 A2 TDI B2 NC C2 COLL I/O9L D1 NC E1 D2 I/O9R E2 I/O10R I/O10L F1 I/O11L G1 NC H1 NC J1 F2 NC G2 NC H2 I/O12R J2 A3 NC B3 A4 A5 A 17L(2) A14L B4 B5 TDO A18L(1) A15L C3 VSS D3 NC E3 NC F3 C4 A 16L D4 C5 A13L D5 E4 E5 VDDQL VDD F4 G4 I/O12L VDDQR H3 F5 H4 G5 VSS H5 NC V DDQR VSS J3 J4 J5 I/O13L I/O14R I/O13R VDDQL ZZR K1 NC L1 I/O15L M1 K2 NC L2 NC M2 I/O16R I/O16L N1 NC P1 N2 I/O17R P2 K3 INT R T1 NC R2 NC T2 TCK K5 L4 L5 I/O15R VDDQR VDD M3 M4 NC VDDQR N3 B6 A 12L C6 A 10L D6 A7 A8L B7 A9L C7 A7L D7 A8 A9 NC CE1L B9 B8 UBL NC LB L D9 D8 A11 A12 OEL CNTENL A 5L B10 B11 CE0L R/WL REPEATL C9 C8 A10 C10 C11 CLKL ADSL D10 D11 B12 A4L C12 A6L D12 N4 M5 VDD N5 E6 VDD E7 NC F7 F6 NC G6 VSS H6 VSS J6 NC G7 VSS H7 VSS J7 VSS K6 V SS L6 NC M6 VDD N6 E9 E8 VSS F9 F8 VSS K7 VSS L7 NC M7 NC N7 VSS G9 G8 V SS H8 VSS H9 V SS J8 VSS VSS VSS J9 VSS K8 VSS K9 V SS L8 VSS L9 V SS VSS M9 M8 VSS N8 VSS N9 E10 VSS F10 VSS G10 VSS H10 VSS J10 VSS K10 VSS L10 VSS M10 VSS N10 E11 VDD F11 VSS G11 VSS H11 VSS J11 VSS K11 VSS L11 VSS M11 VDD N11 E12 P3 R3 P4 A16R R4 P5 A13R R5 TRST A18R(1) A15R T3 NC A13 A2L B13 A1L C13 A3L D13 T4 T5 A17R(2) A14R P6 A 10R R6 A12R T6 A11R P7 A7R R7 A9R T7 A8R P9 P8 NC R8 LB R R9 UBR F12 NC P11 CLKR ADSR R10 R11 CE1R T10 T11 F13 A14 A0L B14 V DD C14 OPTL D14 NC E14 NC F14 VDD VDDQR I/O6R G12 V SS H12 VSS J12 G13 G14 VDDQL I/O5L H13 VDDQL J13 H14 NC J14 A15 A16 NC B15 NC B16 NC NC C16 C15 NC I/O8L D16 D15 NC I/O8R E16 E15 I/O7L I/O7R F16 F15 NC G15 I/O6L G16 NC NC H16 H15 NC I/O5R J16 J15 ZZ L VDDQR I/O4R I/O3R I/O4L K12 V SS L12 VDD M12 VDD N12 P12 A 6R R12 CE0R R/WR REPEATR A 4R T9 T8 P10 E13 V DD VDDQR NC PIPE/ FT R VDDQR VDDQR V DDQL VDDQL VDDQR VDDQR VDDQL VDDQL COLR I/O17L TMS R1 K4 I/O14L VDDQL VSS L3 A11L PIPE/FTL VDDQL VDDQL VDDQR VDDQR VDDQL VDDQL VDDQR VDDQR VDD I/O11R VDDQL VDD G3 A6 T12 OER CNTENR A5R K13 K14 VDDQR NC L13 L14 VDDQL I/O2L M13 M14 VDDQL I/O1R N13 VDD P13 A3R R13 A1R T13 A2R N14 NC P14 NC R14 OPTR T14 A0R K16 K15 NC I/O3L L16 L15 NC I/O2R M16 M15 I/O1L NC N16 N15 I/O0R P15 NC P16 NC I/O0L R16 R15 NC T15 NC , T16 NC NC 5652 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 boundry scan not be operated during sleep mode. 5. Due to limited pin count, JTAG, Collision Detection and Interrupt are not supported in the DD-144 package. 6. Address A18x is a NC for the IDT70T3319. Also, Addresses A18x and A17x are NC's for the IDT70T3399. 7.

"H" = VIH, "L" = VIL, "X" = Don't Care. 2. Read and write operations are controlled by the appropriate setting of R/W, CE0, CE 1, UB, LB 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, UB and LB. 5. The address counter advances if CNTEN = VIL on the rising edge of CLK, regardless of all other memory control signals including CE 0, CE1, UB and LB. 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. 6.42 7 IDT70T3339/19/99S High-Speed 2.5V 512/256/128K x 18 Dual-Port Static RAM Industrial and Commercial Temperature Ranges Maximum Operating Temperature and Supply Voltage(1) Grade Commercial Industrial Ambient Temperature GND VDD 0OC to +70OC 0V 2.5V + 100mV -40OC to +85OC 0V 2.5V + 100mV NOTES: 1.

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. A HIGH on CE0 or 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 IDT70T3339/19/99s for depth expansion configurations. Two cycles are required with CE0 LOW and CE1 HIGH to re-activate the outputs. Interrupts If the user chooses the interrupt function, a memory location (mail box or message center) is assigned to each port. The left port interrupt flag (INTL) is asserted when the right port writes to memory location 7FFFE (HEX), where a write is defined as CER = R/WR = VIL per the Truth Table. The left port clears the interrupt through access of address location 7FFFE when CEL = VIL and R/WL = VIH. Likewise, the right port interrupt flag (INT R ) is asserted when the left port writes to memory location 7FFFF (HEX) and to clear the interrupt flag (INTR), the right port must read the memory location 7FFFF (3FFFF or 3FFFE for IDT70T3319 and 1FFFF or 1FFFE for IDT70T3399). The message (18 bits) at 7FFFE or 7FFFF (3FFFF or 3FFFE for IDT70T3319 and 1FFFF or 1FFFE for IDT70T3399) is user-defined since it is an addressable SRAM location. If the interrupt function is not used, address locations 7FFFE and 7FFFF (3FFFF or 3FFFE for IDT70T3319 and 1FFFF or 1FFFE for IDT70T3399) are not used as mail boxes, but as part of the random access memory. Refer to Truth Table III for the interrupt operation. Collision Detection Collision is defined as an overlap in access between the two ports resulting in the potential for either reading or writing incorrect data to a specific address. For the specific cases: (a) Both ports reading - no data is corrupted, lost, or incorrectly output, so no collision flag is output on either port. (b) One port writing, the other port reading - the end result of the write will still be valid. However, the reading port might capture data that is in a state of transition and hence the reading port's collision flag is output. (c) Both ports writing - there is a risk that the two ports will interfere with each other, and the data stored in memory will not be a valid write from either port (it may essentially be a random combination of the two). Therefore, the collision flag is output on both ports. Please refer to Truth Table IV for all of the above cases. The alert flag (COLX) is asserted on the 2nd or 3rd rising clock edge of the affected port following the collision, and remains low for one cycle. Please refer to Collision DetectionTiming table on Page 21. During that next cycle, the internal arbitration is engaged in resetting the alert flag (this avoids a specific requirement on the part of the user to reset the alert flag). If two collisions occur on subsequent clock cycles, the second collision may not generate the appropriate alert flag. A third collision will generate the alert flag as appropriate. In the event that a user initiates a burst access on both ports with the same starting address on both ports and one or both ports writing during each access (i.e., imposes a long string of collisions on contiguous clock cycles), the alert flag will be asserted and cleared every other cycle. Please refer to the Collision Detection timing waveform on page 21. Collision detection on the IDT70T3339/19/99 represents a significant advance in functionality over current sync multi-ports, which have no such capability. In addition to this functionality the IDT70T3339/19/99 sustains the key features of bandwidth and flexibility. The collision detection function is very useful in the case of bursting data, or a string of accesses made to sequential addresses, in that it indicates a problem within the burst, giving the user the option of either repeating the burst or continuing to watch the alert flag to see whether the number of collisions increases above an acceptable threshold value. Offering this function on chip also allows users to reduce their need for arbitration circuits, typically done in CPLD's or FPGA's. This reduces board space and design complexity, and gives the user more flexibility in developing a solution. Sleep Mode The IDT70T3339/19/99 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. 6.42 23 IDT70T3339/19/99S High-Speed 2.5V 512/256/128K x 18 Dual-Port Static RAM Industrial and Commercial Temperature Ranges Depth and Width Expansion The IDT70T3339/19/99 features dual chip enables (refer to Truth Table I) in order to facilitate rapid and simple depth expansion with no requirements for external logic.
