IDT70T35/34L IDT70T25/24L
Features
◆ True Dual-Ported memory cells which allow simultaneous
reads of the same memory location ◆ High-speed access
IDT70T35/34L (IDT70T25/24L)
– Commercial: 20/25ns (max.)
– Industrial: 25ns (max.) ◆ Low-power operation
– IDT70T35/34L (IDT70T25/24L)
Active: 200mW (typ.) Standby: 600µW (typ.) ◆ Separate upper-byte and lower-byte control for multiplexed
bus compatibility ◆ IDT70T35/34L (IDT70T25/24L) easily expands data bus
width to 36 bits (32 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 Flag ◆ On-chip port arbitration logic ◆ Full on-chip hardware support of semaphore signaling
between ports ◆ Fully asynchronous operation from either port ◆ LVTTL-compatible, single 2.5V (±100mV) power supply ◆ Available in a 100-...
