Description
The EM42BM1684LBA is high speed Synchronous
graphic RAM fabricated with ultra high performance
CMOS process containing 536,870,912 bits which
organized as 8Meg words x 4 banks by 16 bits.
The 512Mb DDR SDRAM uses a double data rate
architecture to accomplish high-speed operation.
The data path internally prefetches multiple bits and
It transfers the datafor both rising and falling edges
of the system clock.It means the doubled data
bandwidth can be achieved at the I/O pins.
Available packages:FBGA-60B(12mmx10mm).
