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.
Specifications and 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) ◆ Industrial temperature range (–40°C to +85°C) is available for selected speeds
Application Scenarios
The IDT7027 can be used in various applications that require high-speed, error-free operation in memory systems. It is commonly used in 32-bit or wider word systems as a stand-alone RAM or in combination with other devices for increased storage capacity. It is also suitable for applications that require low-power operation and compatibility with TTL-compatible systems.
