Preliminary
EMP216MFAF Series
2Mx16 Pseudo Static RAM
GENERAL DESCRIPTION
The EMP216MFAF series is 33,554,432 bits of Pseudo SRAM which uses DRAM type memory cells, but
this device has refresh-free operation and extreme low power consumption technology. Furthermore the
interface is compatible to a low power Asynchronous type SRAM. The EMP216MFAF is organized as
2,097,152 Words x 16 bit.
