Additional Details:

The IS42S32800D-7TLI/TL operates at a clock frequency of up to 143 MHz, indicated by the '-7' in the part number. The 'TLI' and 'TL' suffixes refer to the package type, which is usually TSOP (Thin Small Outline Package). It supports various burst lengths (1, 2, 4, 8, and full page) and burst types (sequential and interleaved). The device incorporates auto precharge and auto refresh functions to simplify memory management and maintain data integrity. It is commonly used as system memory or graphics memory, depending on the application's requirements.
