The AS7C3256A-15TC is a high-performance 256K x 8 Static Random Access Memory (SRAM) device manufactured by Alliance Memory, Inc. This SRAM is designed for applications requiring fast access times and low power consumption. As an end-of-life (EOL) component, it is important to understand its specifications for legacy system maintenance and potential replacements.

Applications

• Cache Memory
• Embedded Systems
• Networking Equipment
• Industrial Control Systems

Features

• Fast Access Time: 15ns access time for quick data retrieval.
• Low Power Consumption: Conserves power, making it suitable for battery-powered applications.
• Single 3.3V Power Supply: Operates on a single 3.3V supply.
• TTL-Compatible Inputs and Outputs: Simplifies interfacing with other digital components.

Benefits

• High-Speed Performance: Fast access time enhances system performance.
• Energy Efficient: Low power consumption extends battery life.
• Easy Integration: TTL-compatible I/O simplifies system design.
• Reliable Operation: Designed for stable and consistent performance.

Technical Specifications

Key specifications include:

• Memory Size: 256K x 8 bits
• Access Time: 15 ns
• Operating Voltage: 3.3V
• Operating Temperature: Typically industrial temperature range (-40°C to +85°C)
• Package Type: TSOP (Thin Small Outline Package)

The AS7C3256A-15TC is packaged in a TSOP, which is ideal for surface mounting on printed circuit boards. Given its EOL status, sourcing this specific component may be challenging, and designers may need to consider alternative SRAM solutions with similar performance characteristics. Reviewing legacy datasheets from Alliance Memory or distributors will provide comprehensive electrical and mechanical specifications.
