The TC55257BPL-10L is a low-power 262,144-bit static RAM (SRAM) from Toshiba Semiconductor and Storage, organized as 32,768 words by 8 bits. Similar to the BFL series, the 'L' designates low power. The 'P' likely refers to the package type, possibly a plastic leaded chip carrier (PLCC) or similar package. The '10L' indicates a 10ns access time with low power consumption. This SRAM is well-suited for battery-powered devices, portable equipment, and embedded systems where both speed and power efficiency are critical.

Applications:

• Portable computing devices (e.g., handhelds, PDAs)
• Battery-backed memory systems
• Low-power embedded controllers
• Wireless communication devices
• Industrial control systems with strict power budgets

Features:

• Access time: 10 ns
• Very Low power consumption: Optimized for battery operation
• Organization: 32,768 words x 8 bits
• Single 5V power supply
• TTL compatible inputs and outputs
• Three-state outputs
• Package: Likely PLCC or similar package type

Benefits:

• Extended battery life: Minimal power consumption allows for prolonged operation in portable devices.
• Reduced heat generation: Low power dissipation simplifies thermal management and allows for denser packaging.
• Fast data access: 10ns access time ensures rapid data retrieval and processing.
• Simplified integration: TTL compatibility and three-state outputs facilitate easy interfacing with other system components.
• Reliable performance: Manufactured by Toshiba, known for high-quality semiconductor products.

Additional Details:

The TC55257BPL-10L operates from a single 5V power supply. It uses TTL-compatible inputs and outputs, simplifying integration with standard logic circuits. The three-state outputs enable flexible memory expansion and bus sharing. The 'P' package type provides a compact and robust mounting option. Consult the Toshiba datasheet for specific power consumption figures and package dimensions.

The combination of low power and fast access time makes this SRAM an excellent choice for demanding portable applications. The PLCC package offers good mechanical stability and ease of handling during assembly.
