Description
The HM66WP18513 is a synchronous fast static RAM organized as 512-Kword
×
18-bit. The
HM66WP36257 is a synchronous fast static RAM organized as 256-Kword
×
36-bit. It has realized high
speed access time by employing the most advanced CMOS process and high speed circuit designing
technology. It is most appropriate for the application which requires high speed, high density memory and
wide bit width configuration, such as cache and buffer memory in system. It is packaged in standard 100-
pin LQFP and 119-pin BGA.
Note : All power supply(V
DD
,V
DDQ
) and ground(V
SS
) pins must be connected for proper operation of the
device.
