Description
HIGH-SPEED
IDT70261S/L
16K x 16 DUAL-PORT
STATIC RAM WITH INTERRUPT
Features
◆ True Dual-Ported memory cells which allow simultaneous access of the same memory location
◆ High-speed access – Commercial: 15/20/25/35/55ns (max.) – Industrial 20/25ns (max.)
◆ Low-power operation – IDT70261S Active: 750mW (typ.) Standby: 5mW (typ.) – IDT70261L Active: 750mW (typ.) Standby: 1mW (typ.)
◆ Separate upper-byte and lower-byte control for multiplexed bus compatibility
◆ IDT70261 easily expands data bus width to 32 bits or more using the Master/Slave select when cascading more than one device
◆ M/S = H for BUSY output flag on Master, M/S = L 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 ◆ TTL-compatible, single 5V (±10%) power supply ◆ Available in 100-pin Thin Quad Flatpack ◆ Industrial temperature range ...
