CY7C149規(guī)格書詳情
Functional Description
The CY7C148 and CY7C149 are high-performance CMOS static RAMs organized as 1024 by 4 bits. Easy memory expansion is provided by an active LOW chip select (CS) input and three-state outputs. The CY7C148 remains in a low-power mode as long as the device remains unselected; i.e., (CS) is HIGH, thus reducing the average power requirements of the device. The chip select (CS) of the CY7C149 does not affect the power dissipation of the device.
Features
? Automatic power-down when deselected (7C148)
? CMOS for optimum speed/power
? 25-ns access time
? Low active power
— 440 mW (commercial)
— 605 mW (military)
? Low standby power (7C148)
— 82.5 mW (25-ns version)
— 55 mW (all others)
? 5-volt power supply ± 10 tolerance, both commercial and military
? TTL-compatible inputs and outputs
