72 Mbit NoBL SRAM — 200 MHz, 3 ns access, 209-BGA
The Cypress CY7C1474BV33-200BGCT is a 72 Mbit synchronous SRAM organized as 1M x 72, built on the NoBL (No Bus Latency) architecture that eliminates dead cycles between reads and writes on consecutive clock edges. Clocked at 200 MHz with a 3 ns access time, it delivers sustained back-to-back throughput for high-bandwidth data buffers in networking, telecom, and compute applications. Supply range is 3.135 V to 3.6 V, and the part is housed in a 209-ball FBGA (14x22 mm) for surface-mount assembly. Temperature grade is commercial: 0 °C to 70 °C.
Obsolete — sourcing through independent channels
This part is marked Obsolete by Cypress (now Infineon). No factory last-time-buy window remains. The only supply path is the surplus and broker market.
209-BGA — layout and assembly considerations
The 209-ball FBGA (14x22 mm) is a fine-pitch BGA. The 0 °C to 70 °C commercial temperature range limits deployment to indoor, climate-controlled environments.
