 HIGH-SPEED 3.3V 256/128K x 18 IDT70V3319/99S SYNCHRONOUS DUAL-PORT STATIC RAM WITH 3.3V OR 2.5V INTERFACE
Features:


True Dual-Port memory cells which allow simultaneous access of the same memory location High-speed data access - Commercial: 3.6ns (166MHz)/4.2ns (133MHz) (max.) - Industrial: 4.2ns (133MHz) (max.) Selectable Pipelined or Flow-Through output mode - Due to limited pin count PL/FT option is not supported on the 128-pin TQFP package. Device is pipelined outputs only on each port. Counter enable and repeat features Dual chip enables allow for depth expansion without additional logic Full synchronous operation on both ports - 6ns cycle time, 166MHz operation (6Gbps bandwidth) - Fast 3.6ns clock to data out - 1.7ns setup to clock and 0.5ns hold on all control, data, and address inputs @ 166MHz


- Data input, address, byte enable and control registers - Self-timed write allows fast cycle time Separate byte controls for multiplexed bus and bus matching compatibility Dual Cycle Deselect (DCD) for Pipelined Output mode LVTTL- compatible, single 3.3V (150mV) power supply for core LVTTL compatible, selectable 3.3V (150mV) or 2.5V (100mV) power supply for I/Os and control signals on each port Industrial temperature range (-40C to +85C) is available at 133MHz. Available in a 128-pin Thin Quad Flatpack, 208-pin fine pitch Ball Grid Array, and 256-pin Ball Grid Array Supports JTAG features compliant to IEEE 1149.1 - Due to limited pin count, JTAG is not supported on the 128-pin TQFP package.

IDT70V3319/99S High-Speed 3.3V 256/128K x 18 Dual-Port Synchronous Static RAM
Industrial and Commercial Temperature Ranges
The IDT70V3319/99 is a high-speed 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 IDT70V3319/99 has been optimized for applications having unidirectional
Description:
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 70V3319/99 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) remains at 3.3V.

NOTES: 1. A17 is a NC for IDT70V3399. 2. VDD, OPTX, and VDDQX must be set to appropriate operating levels prior to applying inputs on the I/Os and controls for that port. 3. OPTX selects the operating voltage levels for the I/Os and controls on that port. If OPTX is set to VIH (3.3V), then that port's I/Os and controls will operate at 3.3V levels and VDDQX must be supplied at 3.3V. If OPTX is set to VIL (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. 4. When REPEATX is asserted, the counter will reset to the last valid address loaded via ADSX. 5. PIPE/FT option in PK-128 package is not supported due to limitation in pin count. Device is pipelined output mode only on each port. 6. Chip Enables and Byte Enables are double buffered when PL/FT = VIH, i.e., the signals take two cycles to deselect.

NOTES: 1. "H" = VIH, "L" = VIL, "X" = Don't Care. 2. Read and write operations are controlled by the appropriate setting of R/W, CE0, CE1, UB, LB and OE. 3. Outputs configured in flow-through output mode: if outputs are in pipelined mode the date out will be delayed by one cycle. 4. ADS and REPEAT are independent of all other memory control signals including CE0, CE1 and UB, LB. 5. The address counter advances if CNTEN = VIL on the rising edge of CLK, regardless of all other memory control signals including CE0, CE1, UB, 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.

NOTES: 1. The Pipelined output parameters (tCYC2, tCD2) apply to either or both left and right ports when FT/PIPEX = VIH. Flow-through parameters (tCYC1, tCD1) apply when FT/PIPE = VIL for that port. 2. All input signals are synchronous with respect to the clock except for the asynchronous Output Enable (OE) and FT/PIPE. FT/PIPE should be treated as a DC signal, i.e. steady state during operation. 3. These values are valid for either level of VDDQ (3.3V/2.5V). See page 5 for details on selecting the desired operating voltage levels for each port.

The output is disabled (High-Impedance state) by CE0 = VIH, CE1 = VIL, UB, LB = VIH following the next rising edge of the clock. Refer to Truth Table 1. 4. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use only. 5.

A READ or WRITE cycle may be coincidental with the counter REPEAT cycle: Address loaded by last valid ADS load will be accessed. Extra cycles are shown here simply for clarification. For more information on REPEAT function refer to Truth Table II. 7. CNTEN = VIL advances Internal Address from `An' to `An +1'.

Functional Description
The IDT70V3319/99 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 is independent of the LOW to HIGH transition of the clock signal. 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 IDT70V3319/99s for depth expansion configurations. Two cycles are required with CE0 LOW and CE1 HIGH to re-activate the outputs.
Depth and Width Expansion
The IDT70V3319/99 features dual chip enables (refer to Truth Table I) in order to facilitate rapid and simple depth expansion with no requirements for external logic. Figure 4 illustrates how to control the various chip enables in order to expand two devices in depth. The IDT70V3319/99 can also be used in applications requiring expanded width, as indicated in Figure 4. Through combining the control signals, the devices can be grouped as necessary to accommodate applications needing 36-bits or wider.

Instruction EXTEST BYPASS IDCODE Code 0000 1111 0010 0011 0001 Description Forces contents of the boundary scan cells onto the device outputs(1). Places the boundary scan registe r (BSR) between TDI and TDO. Places the by pass register (BYR) between TDI and TDO. Loads the ID register (IDR) with the vendor ID code and places the register between TDI and TDO. Places the bypass register (BYR) be tween TDI and TDO. Forces all device output drivers to a High-Z state. Places the boundary scan registe r (BSR) between TDI and TDO. SAMPLE allows data from device inputs (2) to be captured in the boundary scan cells and shifted serially through TDO. PRELOAD allows data to be input serially into the b oundary scan cells via the TDI. Several combinations are reserved. Do not use codes other than those identified above.
