W9864G6JT-6

DRAM Chip SDRAM 64Mbit 4Mx16 3.3V 54Pin TFBGA

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.
