The IDT7134SA55JI is a high-speed, low-power 4K x 4 Dual-Port Static RAM (SRAM) manufactured by Renesas Electronics America. This device provides asynchronous access from either port and is designed for use in applications requiring concurrent access to a shared memory.

Applications

• Telecommunications equipment
• Networking devices
• Data buffering
• Image processing
• High-speed data acquisition systems
• Shared memory applications

Features

• High-speed access time: 55ns
• Low power consumption
• Dual-port operation allows simultaneous access from two independent ports
• On-chip arbitration logic simplifies memory management
• Fully asynchronous operation
• Separate I/O pins for each port
• Available in a ceramic DIP package (JI)
• TTL-compatible inputs and outputs

Benefits

• Increased system performance due to fast access times
• Reduced power consumption extends battery life in portable applications
• Simplified system design with on-chip arbitration
• Eliminates the need for external arbitration logic
• Flexibility in system architecture with dual-port access
• Enhanced data integrity through independent port operation

Technical Specifications

The IDT7134SA55JI operates from a single 5V power supply. It features separate address, data, and control lines for each port, enabling true dual-port operation. The on-chip arbitration logic ensures that only one port can access a memory location at a time, preventing data corruption. The device is available in a 28-pin ceramic DIP (JI) package and is specified for operation over the industrial temperature range.

Additional specifications include:

• Organization: 4K x 4
• Access Time: 55ns
• Operating Voltage: 5V
• Operating Temperature: -40°C to +85°C
• Package Type: 28-Pin Ceramic DIP (JI)
