The 5V configuration (direct replacement of the previous AL422V5) is as follows:
The 3.3V configuration (direct replacement of the previous AL422V3) is as follows:
8.3 Application Notes
8.3.1 Irregular Read/Write
It is recommended that the WCK and RCK are kept running at least 1MHz at all times. The faster one
of WCK and RCK is used as the DRAM refresh timing clock and has to be kept free running. When
irregular FIFO I/O control is needed, keep the clock free running and use /WE or /RE to control the
I/O as follows:
The following drawing shows irregular clock and should be avoided:
