Features
Functional Description
The CY62128V family is composed of three high-performance
CMOS static RAMs organized as 131,072 words by 8 bits.
Easy memory expansion is provided by an active LOW Chip
Enable (CE
Cypress Semiconductor Corporation
• Low voltage range:
• Low active power and standby power
• Easy memory expansion with CE and OE features
• TTL-compatible inputs and outputs
• Automatic power-down when deselected
• CMOS for optimum speed/power
