Infineon CY7C1480BV33-250BZI

2M x 363 нс-40°C ~ 85°C (TA)

Overview

The CY7C1480BV33-250BZI 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 CY7C1480BV33-250BZI 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.

• 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
