Description



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
Counter enable and repeat features
Dual chip enables allow for depth expansion without
additional logic
Interrupt and Collision Detection Flags
Full synchronous operation on both ports
6ns cycle time, 166MHz operation (23.9Gbps bandwidth)
Fast 3.6ns clock to data out
Self-timed write allows fast cycle time
1. Address A17 is a NC for the IDT70T3799.
2. 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.
NOTES:
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
Separate byte controls for multiplexed bus and bus
matching compatibility
Dual Cycle Deselect (DCD) for Pipelined Output Mode
2.5V (±100mV) 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 (-40°C to +85°C) is
available at 133MHz
Available in a 324-pin Green Ball Grid Array (BGA)
Includes JTAG Functionality

Description

The IDT70T3719 is a high-speed 256K/128K x 72 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 IDT70T3719 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 IDT70T3719 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.
