CY7C192 64 K x 4 Static RAM with Separate IO 64 K x 4 Static RAM with Separate IO • High speed 15 ns • CMOS for optimum speed/power • Low active power 860 mW • Low standby power 55 mW • TTL-compatible inputs and outputs • Automatic power down when deselected • Available in Pb-free 28-pin Molded SOJ package Functional Description The CY7C192 is a high performance CMOS static RAM organized as 65,536 x 4 bits with separate IO. Easy memory expansion is provided by active LOW Chip Enable CE and tri-state drivers. It has an automatic power down feature that reduces power consumption by 75% when deselected. Writing to the device is accomplished when the Chip Enable CE and Write Enable WE inputs are both LOW. Data on the four input pins I0 through I3 is written into the memory location specified on the address pins A0 through A15 . Reading the device is accomplished by taking the Chip Enable CE LOW while the Write Enable WE remains HIGH. Under these conditions, the contents of the memory location specified on the address pins appears on the four data output pins. The output pins stay in high impedance state when Write Enable WE is LOW or Chip Enable CE is HIGH. A die coat ensures alpha immunity.
