The 70T653M is a high-speed 256K x 36 Asynchronous Dual-Port Static RAM designed to be used as a stand-alone 18874K-bit Dual-Port RAM. An automatic power down feature controlled by the chip enables (either CE0 or CE1) permit the on-chip circuitry of each port to enter a very low standby power mode.
特性
Dual-Port allows simultaneous access of the same memory location
Dual chip enables allow for depth expansion without external logic
Easily expands data bus width to 72 bits or more using the Busy Input when cascading more than one device
Busy input for port contention management
Interrupt Flags
Full on-chip hardware support of semaphore signaling between ports
Fully asynchronous operation from either port
Separate byte controls for multiplexed bus and bus matching compatibility
Sleep Mode Inputs on both ports
Single 2.5V (±100mV) power supply for core
LVTTL-compatible, selectable 3.3V (±150mV)/2.5V (±100mV) power supply for I/Os and control signals on each port
Includes JTAG functionality
Available in a 256-ball BGA
Industrial temperature range (–40C to +85C) is available
