Functional Description
The CYM1831V33 is a high-performance 3.3V 2-megabit stat-
ic RAM module organized as 64K words by 32 bits. This mod-
ule is constructed from two 64K x 16 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.
The CYM1831V33 is designed for use with standard 64-pin
ZIP sockets. The pinout is compatible with the 64-pin JEDEC
ZIP module family (CYM1821, CYM1831, CYM1836, and
CYM1841). Thus, a single motherboard design can be used to
accommodate memory depth ranging from 16K words
(CYM1821) to 256K words (CYM1841). The CYM1831V33 is
offered in a vertical ZIP configuration.
Presence detect pins (PD
0
PD
1
) are used to identify module
memory density in applications where modules with alternate
word depths can be interchanged.
