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
