CMOS 16,384-Word by 8-Bit
LSI Static ROM
Features:
• Asynchronous operation
• Fast access time - 250 ns max.
• Low standby and operating power -
158Y2=2 pA typical
IOPER2=10 mA max. at tcyc=1 ps;
=30 mA max. at tcyc=250 ns
• Automatic power-down
• Mask-programmable chip enables
and output enable
• TTL input and output compatIble
• 28-pin JEDEC standard pin out
The RCA-COM53128 is a 131 ,072-bit asynchronous mask-
programmable CMOS REAO-ONL Y memory organized as
16,384 eight-bit words. The COM53128 is designed to be
used with a wide range of general-purpose microprocessor
systems, including the RCA COP1800 series system. Two
chip-enable inputs and an output enable function are
provided for memory expansion and output buffer control.
Either chip enable (CE1 or CE2) can gate the address and
output buffers and power down the chip to the standby
mode. The output enable (OE) controls the output buffers
to eliminate bus contention. The polarity of each chip
enable and the output enable are user mask-programmable.
The COM53128 is supplied in 28-lead, hermetic, dual-in-
line sLde-braze<L~elamic (0 suff.!&.. and in 28~jeaddual~
in-line plastic (E suffix) packages.
