DESCRIPTION
The TC55416P/J is a 65,536 bit high speed static random access memory organized as
16,384 words by 4 bits using CMOS technology, and operated from a single 5-volt supply.
Toshiba's high performance device technology provides both high speed and low power
features with a maximum access time of 25ns/35ns/45ns and maximum operating current of
120mA/100mA/100mA at minimum cycle time.
The TC55416P/J also features an automatic stand-by mode. When deselected by Chip Enable
(CE), the operating current is reduced to 20mA.
The TC55416P/J is suitable for use in cache memory and high speed storage, where high
speed/high density are required.
The TC55416P/J is moulded in a 22 pin standard plastic DIP and a 24 pin plastic SOJ,
with 0.3 inch width for high density assembly.
The TC55416P/J is fabricated with ion implanted CMOS silicon gate MOS technology for
high performance and high reliability.
