GENERAL DESCRIPTION

W9864G6JT is a high-speed synchronous dynamic random access memory (SDRAM), organized as 1M words ? x 4 banks x 16 bits. W9864G6JT delivers a data bandwidth of up to 166M words per second. For different application, W9864G6JT is sorted into the following speed grades: -6, -6I, -6A and -6K. They are compliant to the 166MHz/CL3 specification. -6I industrial grade and -6A automotive grade which is guaranteed to support -40°C ≤ TA ≤ 85°C. The -6K automotive grade, if offered, has two simultaneous requirements: ambient temperature (TA) surrounding the device cannot be less than -40°C or greater than +105°C, and the case temperature (TCASE) cannot be less than -40°C or greater than +105°C.
