The TC55464P-20 is a 65,536-bit static RAM (SRAM) organized as 8192 words by 8 bits, manufactured by Toshiba Semiconductor and Storage. It is designed for applications requiring fast access times and low power consumption. The “-20” suffix indicates an access time of 200ns.

Applications:

• Microprocessor Systems: Used as cache memory or main memory in embedded systems.
• Data Acquisition Systems: Employed for temporary storage of data during the acquisition process.
• Industrial Control Systems: Used in applications where quick access to data is critical.
• Instrumentation: Integrated into instruments for data storage and processing.
• Buffer Memory: Used as a buffer to temporarily store data between different system components.

Features:

• Static RAM (SRAM): Requires continuous power to maintain stored data.
• 65,536-bit Capacity: Provides 64KB of storage.
• Organized as 8192 x 8 bits: Byte-wide organization simplifies interfacing with microprocessors.
• Fast Access Time: 200ns access time enables quick data retrieval.
• Low Power Consumption: Reduces power dissipation in battery-powered applications.

Additional Details:

The TC55464P-20 operates on a single 5V power supply. Key specifications include access time, cycle time, and power dissipation. The memory is accessed using address lines, data lines, and control signals (Chip Enable, Output Enable, and Write Enable). It's essential to consult the datasheet for precise timing characteristics, input/output voltage levels, and operating conditions. The device is typically available in a DIP (Dual In-line Package). Proper decoupling capacitors should be used near the power supply pins to minimize noise and ensure stable operation. The TC55464P-20 offers a reliable solution for applications where speed and simplicity are important factors.
