DESCRIPTION

The TC5563APL is 65,536 bit static random

access memory organized as 8,192 words by 8 bits

using CMOS technology, and operates from a single

5V supply. Advanced circuit techniques provide both

high speed and low power features with a maximum

operating current of 5mA/MHz and maximum

access time of 100ns/120ns/150ns. When CE2 is a

logical low or CE? is a logical high, the device is

placed in low power standby mode in which standby

current is 0.6μA typically. The TC5563APL has three

control inputs. Two chip enables (CE1, CE2) allow for

device selection and data retention control, and an

output enable input (OE) provides fast memory

access. Thus the TC5563APL is suitable for use in

various microprocessor application systems where

high speed, low power, and battery back up are

required.

The TC5563APL also features pin compatibility

with the 64k bit EPROM (TMM2764D). RAM and

EPROM are then interchangeable in the same

socket, resulting in flexibility in the definition of the

quantity of RAM versus EPROM in microprocessor

application systems.

The TC5563APL is offered in a dual-in-line 28 pin

0.3 inch width plastic package.
