GENERAL DESCRIPTION


W9864G6KH is a high-speed synchronous dynamic random access memory (SDRAM), organized as  1M words  4 banks  16 bits. W9864G6KH delivers a data bandwidth of up to 200M words per  second. For different application, W9864G6KH is sorted into the following speed grades: -5, -6, -6I and  -7. The -5 parts can run up to 200MHz/CL3. The -6 and -6I parts can run up to 166MHz/CL3 (the -6I  industrial grade which is guaranteed to support -40°C ~ 85°C). The -7 parts can run up to 143MHz/CL3  and with tRP = 18nS.


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. W9864G6KH is ideal for main memory in high  performance applications.

DUAL/QUAD SPI For Industrial & Industrial Plus Grade The W25Q256JV supports standard SPI, Dual SPI and Quad SPI operation. Standard SPI instructions use the unidirectional DI (input) pin to serially write instructions, addresses or data to the device on the rising edge of the Serial Clock (CLK) input pin. Standard SPI also uses the unidirectional DO (output) to read data or status from the device on the falling edge of CLK.
