Functional Description
The CY7C0430V is a 1-Mb synchronous true four-port Static RAM. This is a high-speed, low-power 3.3V CMOS dual-port static RAM. Four ports are provided, permitting independent, simultaneous access for reads from any location in memory.

Features
• True four-ported memory cells which allow simultaneous 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
