CY7C187-20VC

The CY7C187-20VC is designed as high performance CMOS static RAM organized as 65,536 words x1 bit. Easy memory expansion is provided by an active chip enable and three-state drivers. It has an automatic power-down feature, reducing the power consumption by 56% when deselected. Writing to the  CY7C187-20VC  is accomplished when the chip enable and write enable inputs are both low. Data on the input pin (Din) is written into the memory location specified on the address pins (A0 through A15).

The  CY7C187-20VC has six features. (1)High speed 15ns. (2)CMOS for optimum speed/power. (3)Low active power 495mW. (4)Low standby power 220mW. (5)TTL compatible inputs and outputs. (6)Automatic power-down when deselected. Those are all the main features.

Some absolute maximum ratings of  CY7C187-20VC have been concluded into several points as follow. (1)The  CY7C187-20VC's 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 22 to pin 11 would be -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 -0.5V to +7.0V. (6)Its output current into outputs low would be 20mA. (7)Its static discharge voltage would be >2001V. (8)Its latch-up current would be >200mA. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of  CY7C187-20VC 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 voltage would be min 2.2V and max Vcc. (4)Its input low voltage would be min -0.5V and max 0.8V. (5)Its input load current would be min -5uA and max +5uA. (6)Its output leakage current would be min -5uA and max +5uA. (7)Its output short circuit current would be max -350mA. And so on.
