3 / 43 page  W9825G6JH Publication Release Date: Dec. 24, 2013 - 3 - Revision A07 1. GENERAL DESCRIPTION W9825G6JH is a high-speed synchronous dynamic random access memory (SDRAM), organized as 4M words 4 banks 16 bits. W9825G6JH delivers a data bandwidth of up to 200M words per second (-5). To fully comply with the personal computer industrial standard, W9825G6JH is sorted into the following speed grades: -5, -5I, -6, -6I, -6A, -6K, -6L, -75 and 75L. The -5/-5I grade parts are compliant to the 200MHz/CL3 specification (the -5I industrial grade, which is guaranteed to support -40°C ≤ TA ≤ 85°C). The -6 grade parts is compliant to the 166MHz/CL3 or 133MHz/CL2 specification. The -6I/-6A/-6K/-6L grade parts are compliant to the 166MHz/CL3 specification (the -6I industrial grade, -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. The -75/75L is compliant to the 133MHz/CL3 specification. The -6L and 75L parts support self refresh current IDD6 max. 1.5 mA. Accesses to the SDRAM are burst oriented. Consecutive memory location in one page can be accessed at a burst length of 1, 2, 4, 8 or full page when a bank and row is selected by an ACTIVE command. Column addresses are automatically generated by the SDRAM internal counter in burst operation. Random column read is also possible by providing its address at each clock cycle. The multiple bank nature enables interleaving among internal banks to hide the precharging time. By having a programmable Mode Register, the system can change burst length, latency cycle, interleave or sequential burst to maximize its performance. W9825G6JH is ideal for main memory in high performance applications. 2.
