The K4S280832I-UC75 is an SDRAM (Synchronous Dynamic Random-Access Memory) component manufactured by Samsung. SDRAM is a type of dynamic RAM that synchronizes its operation with the system clock, enabling faster data access compared to traditional asynchronous DRAM. This particular part is designed for applications requiring moderate memory capacity and bandwidth, commonly found in embedded systems, graphics cards, and other devices needing temporary data storage.

Applications

• Graphics Cards: Used as frame buffer memory in older graphics cards.
• Embedded Systems: Provides working memory for embedded processors in devices like set-top boxes and industrial controllers.
• Printers: Acts as a buffer for print data.
• Networking Devices: Serves as temporary storage in routers and switches.
• Older Computer Systems: Can be found as main memory in older PCs and laptops.

Features

• Synchronous Operation: Synchronizes memory operations with the system clock for faster data access.
• 256Mb Density: Offers a moderate amount of memory storage capacity.
• 3.3V Power Supply: Operates on a standard 3.3V power supply.
• Multiple Banks: Features multiple internal banks for interleaved memory access, improving performance.
• LVTTL Compatible Inputs and Outputs: Compatible with standard LVTTL logic levels.
• Programmable Burst Length: Supports programmable burst lengths for efficient data transfer.

Benefits

• Faster Data Access: Synchronous operation allows for quicker data access compared to asynchronous DRAM.
• Adequate Memory Capacity: 256Mb density provides sufficient memory for many embedded and graphics applications.
• Compatibility: LVTTL compatible inputs and outputs ensure easy integration with various systems.
• Improved Performance: Multiple banks and programmable burst lengths contribute to improved overall memory performance.
• Cost-Effective: SDRAM offers a cost-effective memory solution for applications that do not require the high bandwidth of more modern memory types.

Additional Details

The K4S280832I-UC75 typically operates at a specific clock frequency determined by the -UC75 suffix (likely 133MHz). It supports various SDRAM features like auto-refresh and self-refresh modes. Key specifications to consider include the operating temperature range, refresh rate, and access times. The device is usually packaged in a TSOP (Thin Small Outline Package) for space-efficient board mounting. Datasheets contain detailed information on timing characteristics, power consumption, and other electrical parameters.
