The CY7C1393KV18-250BZI: It operates at a 250 MHz clock frequency, delivering high burst throughput for pipelined read-write operations in networking, telecom, and high-speed data acquisition systems.
A 250 MHz DDR II SRAM delivers a peak data rate of 500 million transfers per second on an 18-bit bus. That bandwidth matters when you are feeding a high-port-count switch ASIC or a real-time radar processor that cannot stall for DRAM refresh cycles. The synchronous pipeline means the address is latched on one edge and data appears on the next — you budget one clock cycle of latency for reads, which is predictable for timing closure. At this speed, PCB layout needs matched trace lengths and controlled impedance on the data and clock lines; the 165-ball FBGA package (13x15 mm) keeps signal paths short.
Obsolete — what it means for procurement
For existing BOM lines, procurement must source from surplus inventory or the independent broker channel. Availability and pricing vary by lot and date code — we quote each request individually against an RFQ, confirming current availability and market pricing at the time of quote. No last-time-buy window remains; what is on the open market is the only supply.
The device comes in a 165-ball LBGA (13x15 mm FBGA) package, surface-mount only. The Tray shipping medium is standard for BGA devices.
