Description
The IDT70T651/9 is a high-speed 256/128K x 36 Asynchronous Dual-Port Static RAM. The IDT70T651/9 is designed to be used as a stand-alone 9216/4608K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 72-bit-or-more word system. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 72-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.
Features
◆ True Dual-Port memory cells which allow simultaneous access of the same memory location
◆ High-speed access
– Commercial: 8/10/12/15ns (max.)
– Industrial: 10/12ns (max.)
◆ RapidWrite Mode simplifies high-speed consecutive write cycles
◆ Dual chip enables allow for depth expansion without external logic
◆ IDT70T651/9 easily expands data bus width to 72 bits or more using the Master/Slave select when cascading more than one device
◆ M/S = VIH for BUSY output flag on Master, M/S = VIL for BUSY input on Slave
◆ Busy and Interrupt Flags
◆ On-chip port arbitration logic
◆ 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
◆ Supports JTAG features compliant to IEEE 1149.1
◆ 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
◆ Available in a 256-ball Ball Grid Array, 208-pin Plastic Quad Flatpack and 208-ball fine pitch Ball Grid Array.
◆ Industrial temperature range (–40°C to +85°C) is available for selected speeds
