30V
PRELIMINARY
CY7C0430V
3.3V 64K x 18
Synchronous QuadPort™ Static RAM
Features
• True four-ported memory cells which allow simulta-
neous access of the same memory location
• Synchronous Pipelined device
— 64K x 18 organization
• Pipelined output mode allows fast 133-MHz operation
• High Bandwidth up to 10 Gbps (133 MHz x 18 bits wide
x 4 ports)
• 0.25-micron CMOS for optimum speed/power
• High-speed clock to data access 4.7 ns (max.)
• 3.3V Low operating power
— Active = 750mA (maximum)
— Standby = 1mA (maximum)
• Counter wrap-around control
— Internal mask register controls counter wrap-around
— Counter-Interrupt flags to indicate wrap-around
• Counter readback on address lines
• Mask register readback on address lines
• Interrupt flags for message passing
• Master reset for all ports
• Width and depth expansion capabilities
• Dual Chip Enables on all ports for easy depth expansion
• Separate upper-byte and lower-byte controls on all
ports
• 272-BGA package (27 mm x 27 mm 1.27 mm ball pitch)
• Commercial and Industrial temperature ranges
• IEEE 1149.1 JTAG boundary scan
• BIST (Built In Self Test) controller
