The IDT7140SA55P is a high-speed, low-power 4K x 4 Static RAM (SRAM) manufactured by Integrated Device Technology (IDT). This SRAM is designed for applications requiring fast access times and low power consumption. It operates from a single 5V power supply and is available in a variety of package options.

Applications

  
• Cache memory in high-performance systems
  
• Buffer memory in data acquisition systems
  
• Control store memory in microprogrammed systems
  
• High-speed data storage in embedded systems
  
• Digital signal processing (DSP) applications

Features

  
• High-speed access times: 55ns
  
• Low power consumption: Typically draws under 100mA in active mode.
  
• Single 5V power supply operation
  
• Fully static operation: No clock or refresh required
  
• Equal access and cycle times
  
• Available in various package options, including DIP and SOIC
  
• TTL-compatible inputs and outputs

Benefits

  
• Improved system performance due to fast access times
  
• Reduced power consumption, making it suitable for battery-powered applications
  
• Simplified system design due to fully static operation
  
• Increased system reliability due to high-quality manufacturing standards
  
• Easy integration into existing systems due to TTL-compatible I/O

Technical Specifications

The IDT7140SA55P is organized as 4,096 words by 4 bits. It features address inputs, data inputs/outputs, a chip select input, and write enable input. The device operates asynchronously and requires no external clock signals. The data is read from the memory when the chip select input is asserted and the write enable input is deasserted. Data is written to the memory when both the chip select and write enable inputs are asserted. The device provides a high impedance output state when deselected.

Operating Temperature: 0°C to +70°C

Supply Voltage: 5V ± 10%
