Obsolete — what that means for your BOM
Infineon lists the CY7C1270V18-400BZC as Obsolete. For existing designs, the part is sourced through independent distribution — confirmed per RFQ, with availability and pricing quoted at order time.
36 Mbit DDR II SRAM at 400 MHz
The parallel bus delivers double-data-rate throughput — the memory transfers data on both edges of the clock, so the effective data rate is 800 MT/s per pin. That bandwidth suits high-speed cache, network buffers, and telecom line-card applications where latency must stay deterministic.
Package and supply rails
Housed in a 165-ball LBGA (15x17 mm) — the 1.0 mm ball pitch demands a multi-layer PCB for fan-out, and the core supply runs on 1.7 V to 1.9 V. The commercial temperature range (0 °C to 70 °C) limits it to indoor, controlled environments; no industrial or automotive grade here.
