The P2114A-4 is a 4096-bit (4K x 1) static RAM (SRAM) manufactured by Intel. It's a widely used memory component that provides fast access times and simple interface, making it suitable for various applications requiring temporary data storage.

Applications

• Microprocessor memory
• Buffer memory
• Cache memory
• Data storage in embedded systems

Features

• 4096-bit organization (4K x 1)
• Fast access time (450ns for the -4 version)
• Single +5V power supply
• TTL compatible inputs and outputs
• Three-state output
• Fully static operation (no clock or refresh required)

Benefits

• Fast access time allows for quick data retrieval and processing.
• Simple interface reduces design complexity.
• Single +5V power supply simplifies power supply requirements.
• Fully static operation eliminates the need for refresh circuitry, simplifying system design.

Additional Details

The P2114A-4 is typically packaged in a 18-pin DIP (Dual In-line Package). It operates using a single +5V power supply. The access time of 450ns is a characteristic of the "-4" variant. The device is enabled through a chip select (CS) input. The output enable (OE) input controls the output buffer, and the write enable (WE) input controls the write operation. The data input and output share the same pin (I/O). The absence of refresh requirements makes it easy to use in applications where data retention is important but memory density is not critical. The SRAM is a reliable and cost-effective solution for many memory application requirements.
