Obsolete — the procurement reality for this 600 MHz DDR II SRAM
The CY7C1270XV18-600BZXC: The 600 MHz clock rate and 36Mbit (1M x 36) organization place this in the high-bandwidth synchronous SRAM class, typically used in network buffers, test equipment, or high-speed data acquisition where the parallel interface and DDR II throughput are fixed in the BOM. Sourcing this part today means working through independent distribution — surplus or last-time-buy inventory, with date-code provenance and lot traceability confirmed at RFQ.
600 MHz clock, 1.7V-1.9V supply, 165-FBGA footprint
The 600 MHz clock frequency is the headline performance spec — the DDR II interface transfers data on both clock edges, so the effective data rate is 1.2 Gbps per pin. The 36-bit-wide data bus delivers a peak bandwidth of 43.2 Gbps. The 165-ball FBGA package (13x15 mm body) uses a 1.0 mm ball pitch typical of high-density SRAMs from this era. The mounting is surface-mount, and the tray packaging is the standard shipping medium for BGA devices — no tape-and-reel option is listed.
