The 633 MHz clock rate is the headline performance spec. In a DDR II+ SRAM, data is transferred on both edges of the clock, so the effective data rate is 1.266 G transfers per second per pin. For a 36-bit-wide bus, that translates to roughly 45.6 Gbps of raw bandwidth — enough to keep a high-end FPGA or network processor fed without wait states. The trade-off is tighter signal-integrity requirements on the PCB: the 165-ball FBGA (13x15 mm) demands controlled-impedance routing and adequate decoupling close to the supply balls. ## Package and footprint — 165-FBGA (13x15 mm) The 1.7V to 1.9V core supply means the PCB power plane should be sized for the peak current draw at 633 MHz — a typical DDR II+ SRAM at this speed pulls several hundred mA during active bursts.","metaTitle":"Infineon CY7C1570XV18-633BZXC 72Mbit DDR II+ SRAM, 633 MHz","metaDescription":"Infineon CY7C1570XV18-633BZXC 72Mbit synchronous SRAM, DDR II+ architecture, 633 MHz clock, 2M x 36 organization, 165-FBGA, 1.7V-1.9V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, DDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"633 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1570","Memory Organization":"2M x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$409.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/42851f5347eacf4cdc7850e4ea4c568c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1570XV18-633BZXC/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy CY7C1570XV18-633BZXC available via RFQ confirmation?","answer":"The CY7C1570XV18-633BZXC is available to order through independent distribution."},{"question":"What is the clock frequency of CY7C1570XV18-633BZXC?","answer":"The clock frequency is 633 MHz.
