27C16
16,384-Bit (2048 x 8) UV Erasable CMOS PROM
Military Qualified
General Description
Features
Y
Access time down to 450 ns
The 27C16 is a high speed 16K UV erasable and electrically
reprogrammable CMOS EPROM, ideally suited for applica-
tions where fast turnaround, pattern experimentation and
low power consumption are important requirements.
Y
Low CMOS power consumption
Ð Active Power: 26.25 mW max
Ð Standby Power: 0.53 mW max (98% savings)
Performance compatible to NSC800TM CMOS micro-
processor
Y
The 27C16 is packaged in a 24-pin dual-in-line package with
transparent lid. The transparent lid allows the user to ex-
pose the chip to ultraviolet light to erase the bit pattern. A
new pattern can then be written into the device by following
the programming procedure.
