TOSHIBA MOS MEMORY PRODUCT
TC5518CP-15/CPL-15/CP-20/CPL-20
2,048 WORD X 8 BIT CMOS STATIC RAM TC5518CF -15/CFL -15/CF -20/CFL -20
DESCRIPTION
The TC551 8CP/CF is a 16384-bit high speed and
low power sully static random access memory orga-
nized as 2048 words by a 8 bits using CMOS tech-
nology, and operates from a single 5 volt supply.
The TC5518CP/CF has two chip enable inputs, CE1
and CE2, which are used for device selection and
can be used in order to achieve minimum standby
current mode easily for battery back up. Also the
high speed and low power characteristics which
maximum access time is 150ns, 200ns and maxi-
mum operating current is 5mA/MHz are achieved.
Thus the TC5518CP/CF is most suitable for use in .
low power applications where battery operation or
battery back up for nonvolatility are required.
Furthermore the TC5518CPL/CFL guaranteed a·
standby current epual to or less than 1,uA at 60·C
ambient temperature available. And the TC5518CP/
CPL is pin compatible with 2716 type EPROM. This
means that the TC5518CP/CPL and EPROM can be
interchanged in the same socket, and the flexibility in
the definition of the quantity of RAM versus EPROM
allows the wide application in microcomputer system.
