The P2114AL-2 is a 1024 x 4 bit static RAM (SRAM) device. It is typically manufactured by various companies, and Rochester Electronics specializes in providing long-term support and continued availability of such devices, including those that are obsolete or discontinued by the original manufacturer.

Applications

• Microprocessor systems: As a small, fast memory for temporary data storage and program execution.
• Digital signal processing (DSP): Used in DSP applications for high-speed data buffering and calculations.
• Embedded systems: Used as working memory in embedded control systems.
• Instrumentation and control equipment: Providing fast data storage in instruments and control systems.
• Data acquisition systems: Buffering data in real-time data acquisition systems.

Features

• Organization: 1024 x 4 bits: Provides a total of 4096 bits of storage, organized as 1024 words of 4 bits each.
• Static RAM (SRAM): Retains data as long as power is applied, without the need for refreshing.
• Fast access time: The "-2" suffix typically indicates a faster access time, such as 200ns or less. Check the datasheet for the exact value.
• TTL compatible: Directly interfaces with TTL logic levels.
• Single 5V power supply: Operates from a single 5V power source.

Benefits

• High speed: Fast access time makes it suitable for applications requiring quick data retrieval.
• Easy to use: Static RAM requires no refreshing, simplifying system design.
• Low power consumption: SRAMs generally have relatively low power consumption compared to dynamic RAM (DRAM).
• Long-term availability: Rochester Electronics ensures the continued availability of this device, even if the original manufacturer has discontinued it.

Additional Details

The P2114AL-2 typically comes in a 18-pin DIP (Dual In-line Package). The operating temperature range is often between 0°C to +70°C. The device requires a stable 5V power supply for reliable operation. The specific access time will vary but is typically in the range of 150ns to 250ns. Refer to the specific datasheet provided by Rochester Electronics for detailed specifications, including timing diagrams and electrical characteristics.
