Functional Description
The CYM1851V33 is a 3.3V high-performance 32-megabit static RAM module organized as 1,024K words by 32 bits. This module is constructed from eight 1,024K x 4 SRAMs in SOJ
packages mounted on an epoxy laminate substrate. Four chip selects are used to independently enable the four bytes. Reading or writing can be executed on individual bytes or any combination of multiple bytes through proper use of selects.
