Description
The IDT7027 is a high-speed 32K x 16 Dual-Port Static RAM, designed to be used as a stand-alone 512K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.
Features
◆ True Dual-Ported memory cells which allow simultaneous
access of the same memory location
◆ High-speed access
– Military: 25/35/55ns (max)
– Industrial: 25ns (max.)
– Commercial: 20/25/35/55ns (max.)
◆ Low-power operation
– IDT7027S
Active: 750mW (typ.)
Standby: 5mW (typ.)
– IDT7027L
Active: 750mW (typ.)
Standby: 1mW (typ.)
◆ Separate upper-byte and lower-byte control for bus
matching capability.
◆ Dual chip enables allow for depth expansion without
external logic
◆ IDT7027 easily expands data bus width to 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 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 (TQFP) and 108-pin
Ceramic Pin Grid Array (PGA)
