CY7C263-45DMB

The CY7C263-45DMB is designed as one kind of high-performance 8192-word by 8-bit CMOS PROMs. The CY7C263-45DMB  is packaged in a 300-mil-wide package. The CY7C263-45DMB  is packaged in 300-mil-wide and 600-mil-wide packages respectively, and do not power down when deselected. The reprogrammable packages are equipped with an erasure window; when exposed to UV light, these PROMs are erased and can then be reprogrammed. The memory cells utilize proven EPROM floating-gate technology and byte-wide intelligent programming algorithms.
The CY7C263-45DMB has ten features. (1)CMOS for optimum speed/power. (2)Windowed for reprogrammability. (3)High speed 20ns (commercial) and 25ns (military). (4)Low power 660mW (commercial) and 770mW (military). (5)EPROM technology 100% programmable. (6)Slim 300-mil or standard 600-mil packaging available. (7)5V±10% Vcc, commercial and military. (8)Capable of withstanding greater than 2001V static discharge. (9)TTL-compatible I/O. (10)Direct replacement for bipolar PROMs. Those are all the main features.

Some absolute maximum ratings of CY7C263-45DMB have been concluded into several points as follow. (1)Its storage temperature range would be from -65°C to 150°C. (2)Its ambient temperature with power applied would be from -55°C to 125°C. (3)Its supply voltage to ground potential pin 24 to pin 12 would be from -0.5V to 7.0V. (4)Its DC voltage applied to outputs in high Z state would be from -0.5V to 7.0V. (5)Its DC input voltage would be from -3.0V to 7.0V. (6)Its DC program voltage (pin 19 DIP, pin 23 PLCC) would be 13.0V. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of CY7C263-45DMB are concluded as follow. (1)Its output high voltage would be min 2.4V. (2)Its output low voltage would be max 0.4V. (3)Its input high level would be min 2.0V. (4)Its input low level would be max 0.8V. (5)Its input current would be min -10uA and max +10uA. And so on.
