CY7C198

7c198: 10/25/89 Revision: February 29, 1996 Features D D D D D D D High speed Ċ 15 ns CMOS for optimum speed/power Low active power Ċ 990 mW Low standby power Ċ 195 mW Easy memory expansion with CE and OE features TTLĆcompatible inputs and outputs Automatic powerĆdown when deselected The CY7C198 is a highĆperformance CMOS static RAM organized as 32,768 words by8bits.Easymemoryexpansionis provided by an active LOW chip enable (CE)andactiveLOWoutputenable(OE) and threeĆstate drivers. This device has an automatic powerĆdown feature, reducing the power consumption by 80% when deĆ selected. The CY7C198 is available in a 600ĆmilĆwide cerDIP and LCC package and a 32Ćlead TSOP package. An active LOW write enable signal (WE) controls the writing/reading operation of the memory. When CE and WE inputs arebothLOW,dataontheeightdatainput/ Functional Description output pins (I/O0 through I/O7) is written intothememorylocationaddressedbythe address present on the address pins (A0 through A14). Reading the device is acĆ complishedbyselectingthedeviceandenĆ abling the outputs, CE and OE active LOW, while WE remains inactive or HIGH. Under these conditions, the conĆ tents of the location addressed by the inĆ formationonaddresspinsispresentonthe eight data input/output pins. Theinput/outputpinsremaininahighĆimĆ pedance state unless the chip is selected, outputs are enabled, and write enable (WE) is HIGH. A die coat is used to ensure alpha immunity. 32K x 8 Static RAM CY7C198 Logic Block...
