It operates from a 1.7V to 1.9V supply and is housed in a 165-ball FBGA (15x17 mm) for surface-mount assembly. This is a volatile, high-speed memory part designed for applications that demand back-to-back read/write throughput without bus-turnaround dead cycles — think network packet buffers, telecom line cards, or high-end test equipment where the data pipeline cannot stall. The 250 MHz clock rating sets the timing closure target for the controller interface. At this speed, trace-length matching and signal-integrity margins on the parallel bus become design-critical — the FBGA package helps keep inductance low, but the PCB layout still needs controlled impedance and matched-length routes to the memory controller. For a design already running a 250 MHz memory bus, this part drops in without a speed-grade penalty. This part is officially obsolete per the manufacturer — Cypress has discontinued the CY7C1420BV18-250BZC. No last-time-buy window remains open through the original channel. There is no pin-compatible direct replacement listed by the manufacturer, so a drop-in swap will require validating an alternative SRAM against the existing board layout and timing budget. The 1M x 36 organization provides a 36-bit word width.","metaTitle":"Cypress CY7C1420BV18-250BZC SRAM, 36Mbit DDR II, 250 MHz","metaDescription":"Cypress CY7C1420BV18-250BZC synchronous DDR II SRAM, 36Mbit (1M x 36), 250 MHz clock, 1.7-1.9V supply, 165-FBGA.
