70T3799M中文资料128K x 72 Sync, 3.3V/2.5V Dual-Port数据手册Renesas规格书

描述 Description

The 70T3799M is a high-speed 128K x 72 bit synchronous Dual-Port RAM that 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 70T3799M 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.

特性 Features

Dual-Port allows simultaneous access of the same memory location
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
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
Available in a 324-pin BGA package
Includes JTAG Functionality
Industrial temperature range (-40C to +85C) is available
